Summary of the Invention

Problems to be Solved by the Invention

[0004] However, there is a risk that cooling may not be sufficient when the power supply from the commercial power source is interrupted.

[0005] Therefore, an object of the present invention is to provide a computer cooling device and the like that can perform cooling even without power supply from a commercial power source.

Means for Solving the Problems

[0006] The cooling device according to the present invention includes an output terminal portion, a power generation device that generates power based on hydrogen, a computer, a liquid tank that holds a heat medium for cooling the computer, a heat exchange portion that performs heat exchange of the heat medium in the liquid tank, a liquid transfer portion that circulates the heat medium between the liquid tank and the heat exchange portion, a first power storage portion, a second power storage portion that stores the power obtained by the power generation device, a hydrogen generation device that performs electrolysis of an electrolytic solution based on the power from the first power storage portion and generates hydrogen, a hydrogen storage portion that includes a storage portion that stores the hydrogen obtained by the hydrogen generation device, and a switching device that controls the power supply to the computer. The power generation device generates electricity based on at least one of the hydrogen obtained from the hydrogen generator and the hydrogen stored in the storage unit. The power stored in the second energy storage unit is supplied to the first energy storage unit. The electricity generated by the power generation device is supplied to the heat exchange unit and the liquid supply unit via the first energy storage unit and the output terminal unit. When the power supply from the commercial power source to the computer via the switching device is interrupted, the power generated by the power generator is supplied to the computer via the first energy storage unit, the output terminal unit, and the switching device.

[0007] Because a liquid is used as the heat transfer medium, it is possible to cool computers such as servers more efficiently compared to cooling methods that use gases such as air. Cooling using a heat transfer medium circulation is performed based on electricity from two types of power generation devices (the first power generation device and the second power generation device). Therefore, compared to systems where cooling using a heat transfer medium circulation is performed based on electricity from the commercial power supply, the possibility of a cooling failure due to a power outage or other interruption of power supply from the commercial power supply can be reduced.

[Modes for carrying out the invention]

[0017] This embodiment will be described below with reference to the figures. Furthermore, the embodiments are not limited to those described below. In principle, the contents described in one embodiment also apply to other embodiments. Moreover, each embodiment and each variation can be combined as appropriate.

[0018] (Power and hydrogen supply system 1) The power and hydrogen supply system 1 of the first embodiment includes a first power and hydrogen supply station 10a, a second power and hydrogen supply station 10b, a third power and hydrogen supply station 10c, a server 100, electric vehicles (first electric vehicle c1 to fourth electric vehicle c4), power sources under test (first power source under test G1, second power source under test G2), load test devices (rechargeable load test device LB1, electrolytic load test device LB2), and load test mobile devices (first load test mobile device t1, second load test mobile device t2) (see Figures 1 to 3).

[0019] (Electricity and hydrogen supply stations 10a to 3rd electricity and hydrogen supply stations 10c) Each of the first to third power and hydrogen supply stations 10a to 10c has a first power generator 11, a second power generator 12, a control device 13, a charger 14, a station-side display unit 15, a station-side operation unit 16, a fixed energy storage unit 17, a portable energy storage unit 18, loads (first load 19a, second load 19b, third load 19c, fourth load 19d), and a hydrogen storage unit 21 (see Figure 4).

[0020] (First power generator 11) The first power generation device 11 is a power generation device (renewable energy-derived power generation device) that generates electricity based on natural energy (renewable energy), such as a solar power generation device or a wind power generation device. The first power generator 11 is kept in a state where it can generate power at all times. However, if the first power generation device 11 is a wind power generation device and the wind force acting on the first power generation device 11 exceeds a predetermined wind force, the first power generation device 11 will be rendered unable to generate power. The first power generator 11 is installed on the rooftop (enclosure) 25 or similar location. The electricity generated by the first power generator 11 is supplied via the control device 13 to the charger 14, the fixed energy storage unit 17, the portable energy storage unit 18, the loads (first load 19a to fourth load 19d), the hydrogen storage unit 21, and the like.

[0021] (Second power generator 12) The second power generation device 12 is a power generation device (fuel cell) that generates electricity based on hydrogen. The second power generator 12 is made ready to generate power when the power supplied from the first power generator 11 is insufficient. The second power generator 12 is installed inside the building 25 or on the roof of the building 25, etc. The power generated by the second power generator 12 is supplied to the loads (first load 19a to fourth load 19d) via the control device 13. In other words, under normal circumstances, the electricity generated by the second power generator 12 is not supplied to the hydrogen storage unit 21. However, when a load test of the second power generator 12 is performed, as described later, the electricity generated by the second power generator 12 is also supplied to the hydrogen generator 21b and other components of the hydrogen storage unit 21. Furthermore, the water discharged during power generation by the second power generation device 12 may be supplied to the electrolyte supply unit 21a, as shown in the fourth embodiment described later.

[0022] (Control device 13) The control device 13 includes a power conditioner, a distribution board, etc., and performs switching control of the power supply source and switching control of the power supply destination. Specifically, the control device 13 is connected on the input side to the first power generator 11, the second power generator 12, the fixed energy storage unit 17, and the portable energy storage unit 18. Furthermore, the control equipment 13 may be connected to a commercial power receiving device (not shown) on the input side. The control device 13 connects to the charger 14, station-side display unit 15, fixed energy storage unit 17, portable energy storage unit 18, loads (first load 19a, second load 19b, third load 19c, fourth load 19d), hydrogen storage unit 21 (hydrogen generator 21b, heat retention / cooling unit 21c, detection device 21f, hydrogen supply unit 21g), and communication unit 23 on the output side. However, the first power generation device 11 may be directly connected to the portable energy storage unit 18, the hydrogen generator 21b, etc., without going through the control device 13. The control device 13 is installed inside the building 25, or in a similar location.

[0023] (Input switching control) If the power P supplied from the first power generator 11 is less than the power threshold Thp, and the state of charge R1 of the fixed energy storage unit 17 is lower than the first state of charge threshold Thr1, and / or the state of charge R2 of the portable energy storage unit 18 is lower than the second state of charge threshold Thr2, the control device 13 determines that the power supplied from the first power generator 11 etc. is insufficient and connects to the second power generator 12 to receive power from the second power generator 12. In this case, the second power generator 12 receives hydrogen from the hydrogen tank 21d of the hydrogen storage unit 21 and generates electricity. In this case, the hydrogen generator 21b will also be shut down. In this case, the control device 13 may maintain its connection with the first power generator 11, or it may disconnect its connection with the first power generator 11.

[0024] The charge level R2 of the portable energy storage unit 18 refers to the lowest charge level R2 of any of the portable energy storage devices 18b attached to the holding portion 18a of the portable energy storage unit 18.

[0025] However, if the hydrogen filling rate R3 of the hydrogen storage unit 21 is lower than the first hydrogen filling rate threshold Thr3, power will not be supplied from the second power generator 12 to the control device 13. In this case, the control device 13 will receive power from the fixed energy storage unit 17 or the portable energy storage unit 18. The hydrogen filling rate R3 of the hydrogen storage unit 21 shall be the highest value among the hydrogen filling rates R3 of any of the hydrogen tanks 21d attached to the heat retention / cooling unit 21c of the hydrogen storage unit 21. Furthermore, the hydrogen filling rate R3 is defined as the ratio of the amount of hydrogen stored (cc / g or wt%) filled in the hydrogen tank 21d (absorbed by the hydrogen storage alloy) to the maximum amount of hydrogen that can be stored in the hydrogen tank 21d. The hydrogen filling rate R3 is calculated based on the expansion rate of the hydrogen storage alloy, etc., detected by a detection device 21f, such as a strain sensor, attached to the hydrogen storage alloy of the hydrogen tank 21d. Furthermore, the hydrogen filling rate R3 may be calculated based on the amount of hydrogen flowing into the hydrogen tank 21d and the amount of hydrogen being discharged, as detected by a detection device 21f such as a flow sensor installed in the connecting pipe 21e. The connecting pipe 21e communicates with the second power generation device 12 and the hydrogen generator 21b, the hydrogen tank 21d, and the hydrogen supply unit 21g.

[0026] (Priority order for using power supply equipment (1)) In the first embodiment, power from the first power generator 11 is supplied with first priority, power from the fixed energy storage unit 17 with second priority, power from the portable energy storage unit 18 with third priority, and power from the second power generator 12 with fourth priority, to the first loads 19a to the fourth loads 19d, etc.

[0027] In this case, power from the first power generator 11 is supplied via the control device 13 to the station-side display unit 15, the fixed energy storage unit 17, the portable energy storage unit 18, the loads (first load 19a to fourth load 19d), the hydrogen storage unit 21, and the communication unit 23. If the power P supplied from the first power generator 11 is less than the power threshold Thp, power from the fixed energy storage unit 17 is supplied via the control device 13 to the station-side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23. However, power is not supplied from the fixed energy storage unit 17 to the portable energy storage unit 18 and the hydrogen storage unit 21. If the charge rate R1 of the fixed energy storage unit 17 is lower than the first charge rate threshold Thr1, power from the portable energy storage unit 18 is supplied via the control device 13 to the station-side display unit 15, loads (first load 19a to fourth load 19d), and communication unit 23. However, power is not supplied from the portable energy storage unit 18 to the fixed energy storage unit 17 and the hydrogen storage unit 21. If the charge rate R2 of the portable energy storage unit 18 is lower than the second charge rate threshold Thr2, power from the second power generator 12 is supplied via the control device 13 to the station-side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23. However, power is not supplied from the second power generator 12 to the fixed energy storage unit 17, the portable energy storage unit 18, and the hydrogen storage unit 21.

[0028] (Priority of use for power supply equipment (2)) However, the priority order for use of the power supply equipment (first power generator 11, second power generator 12, fixed energy storage unit 17, portable energy storage unit 18) is not limited to the priority order (1) described above. For example, power from the first power generator 11 may be supplied to the first load 19a to the fourth load 19d with first priority, power from the second power generator 12 with second priority, power from the fixed energy storage unit 17 with third priority, and power from the portable energy storage unit 18 with fourth priority.

[0029] In this case, power from the first power generator 11 is supplied via the control device 13 to the station-side display unit 15, the fixed energy storage unit 17, the portable energy storage unit 18, the loads (first load 19a to fourth load 19d), the hydrogen storage unit 21, and the communication unit 23. If the power P supplied from the first power generator 11 is less than the power threshold Thp, power from the second power generator 12 is supplied via the control device 13 to the station-side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23. However, power is not supplied from the second power generator 12 to the fixed energy storage unit 17, the portable energy storage unit 18, and the hydrogen storage unit 21. If the hydrogen filling rate R3 of the hydrogen storage unit 21 is lower than the first hydrogen filling rate threshold Thr3, power from the fixed energy storage unit 17 is supplied to the station-side display unit 15, loads (first load 19a to fourth load 19d), and communication unit 23 via the control device 13. However, power is not supplied from the fixed energy storage unit 17 to the portable energy storage unit 18 and the hydrogen storage unit 21. If the charge rate R1 of the fixed energy storage unit 17 is lower than the first charge rate threshold Thr1, power from the portable energy storage unit 18 is supplied via the control device 13 to the station-side display unit 15, loads (first load 19a to fourth load 19d), and communication unit 23. However, power is not supplied from the portable energy storage unit 18 to the fixed energy storage unit 17 and the hydrogen storage unit 21.

[0030] (Priority order for using power supply equipment (3)) Alternatively, for example, power from the first power generator 11 may be supplied to the first loads 19a to 4th loads 19d with first priority, power from the fixed energy storage unit 17 with second priority, power from the second power generator 12 with third priority, and power from the portable energy storage unit 18 with fourth priority.

[0031] In this case, power from the first power generator 11 is supplied via the control device 13 to the station-side display unit 15, the fixed energy storage unit 17, the portable energy storage unit 18, the loads (first load 19a to fourth load 19d), the hydrogen storage unit 21, and the communication unit 23. If the power P supplied from the first power generator 11 is less than the power threshold Thp, power from the fixed energy storage unit 17 is supplied via the control device 13 to the station-side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23. However, power is not supplied from the fixed energy storage unit 17 to the portable energy storage unit 18 and the hydrogen storage unit 21. If the charge rate R1 of the fixed energy storage unit 17 is lower than the first charge rate threshold Thr1, power from the second power generator 12 is supplied to the station-side display unit 15, loads (first load 19a to fourth load 19d), and communication unit 23 via the control device 13. However, power is not supplied from the second power generator 12 to the fixed energy storage unit 17, the portable energy storage unit 18, and the hydrogen storage unit 21. If the hydrogen filling rate R3 of the hydrogen storage unit 21 is lower than the first hydrogen filling rate threshold Thr3, power from the portable energy storage unit 18 is supplied via the control device 13 to the station-side display unit 15, loads (first load 19a to fourth load 19d), and communication unit 23. However, power is not supplied from the portable energy storage unit 18 to the fixed energy storage unit 17 and the hydrogen storage unit 21.

[0032] In other words, the control device 13 adjusts the power supplied from the first power generator 11, the second power generator 12, and the energy storage devices (fixed energy storage unit 17, portable energy storage unit 18) based on the usage priority set using the station-side operation unit 16 or the like.

[0033] However, the control device 13 may determine the priority order of use according to the usage status of the second power generator 12, the fixed energy storage unit 17, and the portable energy storage unit 18, and adjust the power supplied from the first power generator 11, the second power generator 12, and the energy storage devices (fixed energy storage unit 17, portable energy storage unit 18) based on the priority order of use determined by the control device 13.

[0034] For example, if the time Ta during which power is supplied from the portable energy storage unit 18 during the first hour TT1 (for example, TT1 = 24 hours) from the present is shorter than the time threshold Tht, the control device 13 determines the priority order of use so that power from the first power generator 11 is supplied with first priority, power from the fixed energy storage unit 17 with second priority, power from the portable energy storage unit 18 with third priority, and power from the second power generator 12 with fourth priority, to the first load 19a to the fourth load 19d, etc.

[0035] Furthermore, for example, if the time Tb during which power is supplied from the fixed energy storage unit 17 during the first time period TT1 from the present is longer than the time Tc during which power is supplied from the second power generator 12, the control device 13 determines the priority order of use so that power from the first power generator 11 is supplied with first priority, power from the second power generator 12 with second priority, power from the fixed energy storage unit 17 with third priority, and power from the portable energy storage unit 18 with fourth priority, to the first load 19a to the fourth load 19d.

[0036] Furthermore, for example, if the time Tb during which power is supplied from the fixed energy storage unit 17 during the first time period TT1 from the present is shorter than the time Tc during which power is supplied from the second power generator 12, the control device 13 determines the priority order of use so that power from the first power generator 11 is supplied with first priority, power from the fixed energy storage unit 17 with second priority, power from the second power generator 12 with third priority, and power from the portable energy storage unit 18 with fourth priority, to the first load 19a to the fourth load 19d.

[0037] In any of the above-mentioned priority order (1), priority order (2), and priority order (3), a configuration was described in which power is not supplied from the fixed energy storage unit 17 to the portable energy storage unit 18 and the hydrogen storage unit 21, power is not supplied from the portable energy storage unit 18 to the fixed energy storage unit 17 and the hydrogen storage unit 21, and power is not supplied from the second power generation device 12 to the fixed energy storage unit 17, the portable energy storage unit 18, and the hydrogen storage unit 21. However, taking into consideration the supply and demand balance of electricity, hydrogen, portable energy storage device 18b, and hydrogen tank 21d supplied to the first electric vehicle c1, at least one of the following may be performed: supplying electricity from the fixed energy storage unit 17 to the portable energy storage unit 18 and the hydrogen storage unit 21; supplying electricity from the portable energy storage unit 18 to the fixed energy storage unit 17 and the hydrogen storage unit 21; and supplying electricity from the second power generation device 12 to the fixed energy storage unit 17, the portable energy storage unit 18, and the hydrogen storage unit 21.

[0038] (Output switching control) The control device 13 is connected to the fixed energy storage unit 17. However, if the charge rate R1 of the fixed energy storage unit 17 is close to a fully charged state, and the power P supplied from the first power generator 11 is greater than or equal to the power threshold Thp, then sufficient power can be supplied from the first power generator 11 to the loads (first load 19a to fourth load 19d), the portable energy storage unit 18, and the hydrogen storage unit 21 without using the power stored in the fixed energy storage unit 17. For this reason, in such cases, the control device 13 disconnects the connection with the fixed energy storage unit 17.

[0039] The portable energy storage unit 18 and the control device 13 are permanently connected. However, if the charge levels R2 of all portable energy storage devices 18b attached to the holding portion 18a of the portable energy storage unit 18 are close to a fully charged state, the control device 13 disconnects the connection with the portable energy storage unit 18. In this case, the control device 13 displays a first replacement notice on the station-side display unit 15 indicating that the fully charged portable energy storage device 18b should be removed from the holding unit 18a and the uncharged portable energy storage device 18b should be attached to the holding unit 18a, or the first replacement notice is displayed on the user's mobile terminal at the first power / hydrogen supply station 10a via the communication unit 23. After the replacement of the portable energy storage device 18b, the control device 13 connects to the portable energy storage unit 18.

[0040] The control device 13 is connected to the load (first load 19a, second load 19b, third load 19c, fourth load 19d) that has been turned ON by the user or other party.

[0041] The hydrogen storage unit 21 and the control device 13 are always connected. However, if the hydrogen filling rate R3 of all hydrogen tanks 21d attached to the heat retention / cooling section 21c of the hydrogen storage section 21 is higher than or equal to the second hydrogen filling rate threshold Thr4 (Thr4 > Thr3), the control device 13 will consider the hydrogen tanks 21d to be sufficiently filled with hydrogen and will disconnect the connection to the hydrogen storage section 21. In this case, the control device 13 displays a second replacement notice on the station-side display unit 15 indicating that the hydrogen-filled hydrogen tank 21d will be removed from the heat insulation / cooling unit 21c and the hydrogen tank 21d that has not yet been filled with hydrogen will be attached to the heat insulation / cooling unit 21c, or the second replacement notice will be displayed on the mobile terminal of the user of the first power / hydrogen supply station 10a via the communication unit 23. After the replacement of the hydrogen tanks 21d, the control device 13 connects to the hydrogen storage unit 21.

[0042] The control device 13 is connected to the communication unit 23.

[0043] (Conversion between AC and DC) In the first embodiment, the power passing through the control device 13 is assumed to be alternating current. Therefore, a device (not shown) that converts power from DC to AC is provided between the DC power generating device and the control device 13 of the first power generation device 11 and the second power generation device 12. Furthermore, a device (first converter 13a) is provided between the fixed energy storage unit 17 and the control device 13 to convert power from alternating current to direct current, or to convert it to a predetermined current and voltage. Furthermore, a device (second converter 13b) is provided between the portable power storage unit 18 and the control device 13 to convert power from alternating current to direct current, or to convert it to a predetermined current and voltage. Furthermore, between the station-side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23, which is driven by DC, and the control device 13, a device (not shown) is provided that converts power from AC to DC, or converts it to a predetermined current and voltage. Furthermore, a device (not shown) is provided between the hydrogen generator 21b and the control device 13 to convert power from alternating current to direct current, or to convert it to a predetermined current and voltage.

[0044] However, the power passing through the control device 13 may be DC. In this case, a device for converting power from AC to DC is provided between the device that generates AC power in the first power generation device 11 and the control device 13 in the second power generation device 12. Furthermore, a device for converting power from DC to AC is provided between the station-side display unit 15, the loads (first load 19a to fourth load 19d), and the communication unit 23, specifically between the AC-driven components and the control device 13. In this case, the first converter 13a and the second converter 13b function as devices that convert to predetermined current and voltage.

[0045] (Charger 14) The charger 14 is connected to the first electric vehicle c1 in a detachable manner and supplies power from the first power generator 11 to the first electric vehicle c1. Alternatively, the charger 14 may supply power from the first electric vehicle c1 to a fixed energy storage unit 17. In this case, the charger 14 has a charging device (first converter 14a) that is connected to the charging terminal of the first electric vehicle c1 and charges the in-vehicle energy storage device 31a of the first electric vehicle c1, and a V2H device (second converter 14b) that is connected to the power supply terminal of the first electric vehicle c1 and discharges the in-vehicle energy storage device 31a of the first electric vehicle c1.

[0046] (Station-side display unit 15, station-side operation unit 16) The station-side display unit 15 displays charging information for the fixed energy storage unit 17, charging information for the portable energy storage device 18b attached to the holding unit 18a of the portable energy storage unit 18, hydrogen filling rate information for the hydrogen tank 21d attached to the heat retention / cooling unit 21c of the hydrogen storage unit 21, information regarding the priority of use of the power supply equipment (first power generator 11, second power generator 12, fixed energy storage unit 17, portable energy storage unit 18), reservation information from the first electric vehicle c1, etc. The station-side control unit 16 is used for setting the usage priority, etc.

[0047] The station-side display unit 15 and the station-side operation unit 16 may be integrated as a single unit, such as a touch panel, or they may be configured as separate units. Furthermore, the station-side display unit 15 and the station-side operation unit 16 may be fixed to the building 25 of the first power and hydrogen supply station 10a, or they may be fixed in a manner that allows them to be attached and detached. Furthermore, a user's mobile device or the like at least one of the station-side display unit 15 and the station-side operation unit 16 may function as the user's mobile device or the like at the station-side display unit 15 and the station-side operation unit 16.

[0048] (Fixed energy storage unit 17) The fixed energy storage unit 17 has an energy storage device that stores electricity from the first power generation device 11 and the like. The energy storage device of the fixed energy storage unit 17 is fixed in a predetermined location inside the building 25 without consideration for attachment or detachment.

[0049] The fixed energy storage unit 17 supplies stored power to loads (first load 19a to fourth load 19d) via the control device 13 when the power supply from the first power generator 11 is insufficient. Furthermore, the fixed energy storage unit 17 also supplies power to the electrical equipment (such as the station-side display unit 15) that constitutes the first power and hydrogen supply station 10a, as an auxiliary power source. However, a separate energy storage device for this auxiliary power source may be provided in addition to the fixed energy storage unit 17.

[0050] The first converter 13a and the fixed energy storage unit 17 may be used as a rechargeable load test area for performing load tests on power supply devices such as the first power generator 11. In this case, at least one of the first converter 13a and the fixed energy storage unit 17 has a first variable structure for adjusting the load amount when performing an electrolytic load test.

[0051] For example, the first variable structure includes a first converter 13a which has multiple AC / DC converters. These multiple AC / DC converters are connected in parallel and connected to one of the energy storage devices of the fixed energy storage unit 17. The load is adjusted by changing the number of AC / DC converters used when power is supplied from the power source under test (power supply device such as the first power generator 11) to the fixed energy storage unit 17 via the control device 13.

[0052] Furthermore, for example, the fixed energy storage unit 17 as the first variable structure has multiple energy storage devices. These multiple energy storage devices are connected in parallel and connected to one AC / DC converter of the first converter 13a. The load is adjusted by changing the number of these multiple energy storage devices that receive power from the power source under test (power supply device such as the first power generator 11) via the control device 13 and the first converter 13a.

[0053] Furthermore, for example, in the first variable structure, the first converter 13a has multiple AC / DC converters, and the fixed energy storage unit 17 has multiple energy storage devices. The multiple AC / DC converters are connected in parallel. The multiple energy storage devices are connected in parallel. Each of the multiple AC / DC converters is connected to the multiple energy storage devices. Therefore, multiple sets of AC / DC converters and energy storage devices connected in series are provided. The load is adjusted by changing the number of sets of multiple AC / DC converters and energy storage devices that receive power from the power source under test (power supply device such as the first power generator 11) via the control device 13.

[0054] (Portable energy storage unit 18) The portable energy storage unit 18 has a holding unit 18a and a portable energy storage device 18b. The holding part 18a holds the portable energy storage device 18b in a detachable state. The portable energy storage device 18b is an energy storage device that stores electricity from the first power generation device 11 and the like. The portable energy storage device 18b is detachable from the holding part 18a and can be attached to other electrical equipment, such as the second electric vehicle c2 described later, in a detachable manner, and drives said other electrical equipment. The portable energy storage device 18b supplies stored power to loads (first load 19a to fourth load 19d) via the control device 13 when the power supply from the first power generator 11 is insufficient.

[0055] Furthermore, the storage of electricity in the portable energy storage device 18b may not only be performed at the first power and hydrogen supply station 10a, but may also be performed outside of the first power and hydrogen supply station 10a. For example, a portable energy storage device 18b mounted on the first load test mobile device t1 together with the rechargeable load test device LB1 can be configured to store power supplied from the first test target power source G1 via the rechargeable load test device LB1 (see Figure 3). The rechargeable load test device LB1 performs a load test on the first test target power source G1 by charging the portable energy storage device 18b with power from the first test target power source G1. Furthermore, the portable energy storage device 18b can be held in the holding section 18a of the second power and hydrogen supply station 10b, and can be configured to store electricity supplied from the first power generation device 11 of the second power and hydrogen supply station 10b.

[0056] In the first embodiment, three holding units 18a are provided, and an example is shown in which three portable energy storage devices 18b can be charged simultaneously. However, the number of holding units 18a is not limited to three.

[0057] The holding part 18a of the portable power storage unit 18 is installed inside the building 25 or the like.

[0058] The second converter 13b and the portable energy storage unit 18 may be used as a rechargeable load test area for performing additional tests on power supply devices such as the first power generator 11. In this case, at least one of the second converter 13b and the portable energy storage unit 18 has a second variable structure for adjusting the load amount when performing an electrolytic load test.

[0059] For example, the portable energy storage unit 18 as the second variable structure has a plurality of portable energy storage devices 18b. These plurality of portable energy storage devices 18b are connected in parallel and connected to one AC / DC converter of the second converter 13b. The load is adjusted by changing the number of these plurality of portable energy storage devices 18b that receive power from the power source under test (power supply device such as the first power generator 11) via the control device 13 and the second converter 13b.

[0060] Furthermore, for example, in the second variable structure, the second converter 13b has multiple AC / DC converters, and the portable energy storage unit 18 has multiple portable energy storage devices 18b. The multiple AC / DC converters are connected in parallel. The multiple portable energy storage devices 18b are connected in parallel. Each of the multiple AC / DC converters is connected to the multiple portable energy storage devices 18b. Therefore, multiple sets of AC / DC converters and portable energy storage devices 18b connected in series are provided. The load is adjusted by changing the number of sets of multiple AC / DC converters and portable energy storage devices 18b that receive power from the power source under test (power supply device such as the first power generator 11) via the control device 13.

[0061] (1st load 19a~4th load 19d) The first load 19a to the fourth load 19d are electrical appliances installed inside or near the building 25, such as light bulbs, elevators, refrigerators, air conditioners, and televisions. Of the first load 19a to the fourth load 19d, power is supplied via the control device 13 to the load that the user has operated to turn on. At least one of the first load 19a to the fourth load 19d may be a load testing device for performing load testing on a power supply device such as the first power generator 11.

[0062] (Hydrogen storage unit 21) The hydrogen storage unit 21 includes an electrolyte supply unit 21a including a water intake unit 21a1, a hydrogen generator 21b, a heat retention / cooling unit 21c, a hydrogen tank 21d, a connecting pipe 21e, a detection device 21f, and a hydrogen supply unit 21g.

[0063] The electrolyte supply unit 21a supplies an electrolyte such as water to the hydrogen generator 21b for electrolysis.

[0064] The electrolyte is collected at the water intake section 21a1. The water intake section 21a1 is a dehumidifier that condenses moisture from the air and collects the condensed water as an electrolyte. The dehumidifying device is composed, for example, of a cooling plate, a heat sink plate, and a thermoelectric element (Peltier element) placed between them. In the first embodiment, the cooling plate is installed inside the building 25 to condense moisture contained in the air inside the building 25. However, the cooling plate may also be installed outside the building 25 to condense moisture in the air outside the building 25. Furthermore, some of the air conditioners in building 25 may function as dehumidifiers, and the water produced by condensation during the operation of these air conditioners may be collected as an electrolyte. Furthermore, the water intake section 21a1 may be configured to collect rainwater from above the building 25, water stored around the building 25, and water from rivers flowing around it. Furthermore, the dehumidifier may also be used to extract moisture contained in the gas (oxygen, hydrogen) generated by electrolysis in the hydrogen generator 21b.

[0065] The hydrogen generator 21b generates hydrogen by performing electrolysis based on electricity supplied from the first power generator 11 and the like. The electrolyte supply unit 21a and the hydrogen generator 21b may be configured as separate units or as an integrated unit.

[0066] The hydrogen generator 21b may also be used as an electrolytic load test area for performing load tests on power supply devices such as the first power generator 11. The load amount in the electrolytic load test area is adjusted by controlling the supply of electrolyte from the electrolyte supply unit 21a to the hydrogen generator 21b, controlling the movement of at least one electrode in the hydrogen generator 21b, and controlling the movement of the insulator between one electrode and the other in the hydrogen generator 21b. In other words, at least one of the electrolyte supply unit 21a and the hydrogen generator 21b has a third variable structure for adjusting the load amount when performing an electrolysis load test.

[0067] For example, in the third variable structure, multiple electrodes (e.g., cathodes) are provided. The load is adjusted by changing the number of cathodes among the multiple electrodes through which current from the power supply under test (e.g., the first power generator 11) flows.

[0068] Furthermore, as a third variable structure, for example, at least one of the electrodes (e.g., cathode 21b1) is configured to be movable in the vertical direction. The load is adjusted by changing the contact area between the at least one electrode that is movable in the vertical direction and the electrolyte (electrode movement control, see Figure 7). Figure 7 shows an example in which a container holding the electrolyte constitutes the anode 21b2, a cathode 21b1 is provided inside the container, and the cathode 21b1 is held in a state in which it is movable in the vertical direction by a holding mechanism 21b3, that is, in a state in which the contact area with the electrolyte can be varied.

[0069] Furthermore, for example, the third variable structure is configured to adjust the amount of electrolyte supplied to the hydrogen generator 21b. By changing the amount of electrolyte, the contact area between the electrode and the electrolyte is changed, thereby adjusting the load (electrolyte supply control).

[0070] Furthermore, as the third variable structure, an insulator 21b4 is provided that is configured to be movable between one electrode (e.g., cathode 21b1) and the other electrode (e.g., anode 21b2). The load is adjusted by changing the degree of shielding between the electrodes by the insulator 21b4 (insulator movement control, see Figure 8). Figure 8 shows an example in which a cathode 21b1 and an anode 21b2 are provided inside a container that holds an electrolyte, an insulator 21b4 is provided between the cathode 21b1 and the anode 21b2, and the insulator 21b4 is held in a state that it can move vertically by a holding mechanism 21b3.

[0071] The third variable structure allows for easier fine-tuning of the load compared to the rechargeable load test region. Therefore, the rechargeable load test region is used for adjusting large loads, while the electrolytic load test region is used for adjusting small loads.

[0072] The heat retention / cooling unit 21c holds the hydrogen tank 21d in a detachable state and heats or cools the held hydrogen tank 21d. Specifically, when storing hydrogen generated by the hydrogen generator 21b, the heat retention and cooling unit 21c cools the hydrogen tank 21d that it holds. When hydrogen is released from the hydrogen tank 21d, the heat retention and cooling unit 21c either heats the hydrogen tank 21d it holds or stops cooling it. However, as shown in the fourth embodiment described later, the hydrogen tank 21d may be heated using heat obtained from a device other than the heat retention / cooling unit 21c, such as a solar water heater 20.

[0073] The hydrogen tank 21d has a hydrogen storage alloy that absorbs hydrogen and a container that holds the hydrogen storage alloy. The container of the hydrogen tank 21d holds the hydrogen storage alloy inside. The hydrogen tank 21d absorbs hydrogen under high pressure or low temperature, and releases the absorbed hydrogen when the high pressure or low temperature conditions are not met. The hydrogen tank 21d is connected to the second power generation device 12, the hydrogen generator 21b, and the hydrogen supply unit 21g via a connecting pipe 21e. Furthermore, moisture (such as drain water) contained in the gas of the hydrogen generator 21b, hydrogen tank 21d, and connecting pipe 21e may be supplied to the electrolyte supply unit 21a, as shown in the fourth embodiment described later.

[0074] A detection device 21f, such as a strain sensor or a flow sensor, is provided in at least one of the hydrogen tank 21d and the connecting pipe 21e. The detection device 21f is used to calculate the degree of hydrogen filling in the hydrogen tank 21d (hydrogen filling rate R3).

[0075] In the first embodiment, the hydrogen tank 21d is described as portable, detachable from the heat-insulating / cooling unit 21c, and capable of being mounted on the fourth electric vehicle c4 and the second load test mobile device t2, which will be described later. However, at least one of the hydrogen tanks 21d may be fixed to the heat-insulating / cooling unit 21c or the like without regard to detachment. Furthermore, in the first embodiment, a configuration is described in which the hydrogen tank 21d stores hydrogen by adsorption into an adsorption alloy. However, the hydrogen tank 21d may also store hydrogen in the form of an organic hydride containing hydrogen, liquefied hydrogen, or compressed gaseous hydrogen.

[0076] The hydrogen supply unit 21g is connected to the third electric vehicle c3 in a detachable manner and supplies hydrogen from the hydrogen tank 21d or the like to the in-vehicle fixed hydrogen storage device 31c of the third electric vehicle c3. Furthermore, a high-pressure hydrogen tank or the like may be connected to the hydrogen supply unit 21g in a detachable manner. In this case, hydrogen from the high-pressure hydrogen tank or the like may be supplied to the hydrogen tank 21d or the like.

[0077] Furthermore, the storage (absorption) of hydrogen into the hydrogen tank 21d may not only be carried out at the first power and hydrogen supply station 10a, but may also be carried out outside of the first power and hydrogen supply station 10a. For example, the hydrogen tank 21d mounted on the second load test mobile device t2, along with the electrolytic load test device LB2, can be configured to store hydrogen generated from the second test target power source G2 via the electrolytic load test device LB2 (see Figure 3). The electrolytic load test device LB2 uses electricity from the second test target power supply G2 to electrolyze an electrolyte such as water, and then absorbs the hydrogen obtained from the electrolysis into the hydrogen tank 21d, thereby performing a load test on the second test target power supply G2. Furthermore, the hydrogen tank 21d is held in the heat retention / cooling section 21c of the second power / hydrogen supply station 10b, and a configuration is conceivable in which hydrogen based on electricity supplied from the first power generator 11 of the second power / hydrogen supply station 10b is stored.

[0078] (Buffer tank) Furthermore, a buffer tank 21d1 for temporarily storing hydrogen may be provided in the connecting pipe 21e between the hydrogen generator 21b and the hydrogen tank 21d, and between the hydrogen tank 21d and the hydrogen supply unit 21g.

[0079] (Depressurization device) Furthermore, the connecting pipe 21e may be provided with a pressure reducing device 21d2 for adjusting the pressure.

[0080] (Communications Section 23) The communication unit 23 transmits to the server 100 location information of the first power and hydrogen supply station 10a, including the communication unit 23, business information, charging information of portable energy storage devices 18b attached to the holding unit 18a of the portable energy storage unit 18, and hydrogen filling rate information of the hydrogen tank 21d attached to the heat retention / cooling unit 21c of the hydrogen storage unit 21. The charging information and hydrogen refueling rate information are transmitted via server 100 to the first electric vehicle c1, which will be described later. The communication unit 23 receives information from the server 100 regarding the power stored in the fixed energy storage unit 17 and other devices, the charged portable energy storage device 18b, the filled hydrogen tank 21d, and reservations for the purchase or exchange of hydrogen filled in the hydrogen tank 21d.

Furthermore, the in-vehicle energy storage device 31a supplies power to the fixed energy storage unit 17 and the like via the second converter 14b of the charger 14.

[0085] (1st communication department 33a) The first communication unit 33a transmits location information of the first electric vehicle c1 and other data to the server 100. The first communication unit 33a receives charging information for the fixed energy storage units 17 at each of the first power and hydrogen supply stations 10a to the third power and hydrogen supply stations 10c from the server 100.

[0086] (First display section 35a) The first display unit 35a displays charging information including the operating hours of the first power and hydrogen supply stations 10a to the third power and hydrogen supply stations 10c, the time required from the current location of the first electric vehicle c1, the charging status of the fixed energy storage unit 17, and whether reservations are possible (see Figure 5).

[0087] The charging information will display the reservation instruction button 35a1 if it is possible to reserve the purchase of electricity from a fully charged fixed energy storage unit 17 among the first to third power and hydrogen supply stations 10a to 10c. When a predetermined first operation is performed, such as touching the reservation instruction button 35a1, information regarding the reservation is transmitted or a call is made to the power and hydrogen supply station corresponding to the reservation instruction button 35a1 via the server 100. The transmission of reservation information includes information about the first electric vehicle c1 or the user of the first electric vehicle c1, estimated arrival time, and information about purchasing electricity. If a call is initiated, a call will be initiated via the first communication unit 33a, followed by a call between the user of the first electric vehicle c1 and the user of the corresponding power / hydrogen supply station.

The route Ru may be a route calculated with the power and hydrogen supply station corresponding to the route guidance button 35a2 as the final destination Dp, or, if a route to another destination has been set before the second operation, the route Ru may be a route calculated with that other destination as the final destination and the power and hydrogen supply station corresponding to the route guidance button 35a2 as an intermediate stop.

[0089] Furthermore, when the first operation is performed, the route Ru to the power / hydrogen supply station corresponding to the reservation instruction button 35a1 may be displayed (see Figure 6). Figure 6 shows an example in which, before the first operation is performed, no route settings have been made to any other destination, a reservation has been made to purchase or replace a portable energy storage device 18b at the second power / hydrogen supply station 10b, and the route Ru from the current location Cp is displayed on the first display unit 35a with the second power / hydrogen supply station 10b as the final destination Dp.

[0119] (4th Communications Section 33d) The fourth communication unit 33d transmits location information of the fourth electric vehicle c4 and other data to the server 100. The fourth communication unit 33d receives from the server 100 information such as hydrogen refueling information for hydrogen tanks 21d at each of the first power and hydrogen supply stations 10a to the third power and hydrogen supply stations 10c.

[0120] (Fourth display section 35d) The fourth display unit 35d displays charging information including the operating hours of the first power and hydrogen supply stations 10a to the third power and hydrogen supply stations 10c, the time required from the current location of the fourth electric vehicle c4, the hydrogen refueling status of the hydrogen tank 21d, and whether reservations are possible (not shown).

[0121] If each of the first to third power and hydrogen supply stations 10a to 10c is filling multiple types of hydrogen tanks 21d with hydrogen, it is desirable that only the information related to the hydrogen tank holding section 31d of the fourth electric vehicle c4 among the multiple types of hydrogen tanks 21d be displayed as hydrogen filling information.

[0122] The hydrogen refueling information will display a reservation button if it is possible to reserve a hydrogen-filled hydrogen tank 21d at one of the first to third power and hydrogen supply stations 10a to 10c, or to exchange it for a hydrogen tank 21d held by the fourth electric vehicle c4. When a predetermined first operation is performed, such as touching the reservation instruction button on the fourth display unit 35d, reservation information is transmitted or a call is made to the power and hydrogen supply station corresponding to the reservation instruction button via the server 100. The transmission of reservation information includes information about the fourth electric vehicle c4 or the user of the fourth electric vehicle c4, the estimated time of arrival, and the type of hydrogen tank 21d to be purchased or replaced. If a call is initiated, the call will begin via the fourth communication unit 33d, followed by a call between the user of the fourth electric vehicle c4 and the user of the corresponding power / hydrogen supply station.

[0123] The hydrogen refueling information displays route guidance buttons from the current location of the fourth electric vehicle c4 to each of the power and hydrogen supply stations 10a, 10a, 2010, and 10c. When a predetermined second operation is performed, such as touching the route guidance button on the fourth display unit 35d, the route Ru from the current location of the fourth electric vehicle c4 to the power / hydrogen supply station corresponding to the route guidance button is displayed. The route Ru may be a route calculated with the power and hydrogen supply station corresponding to the route guidance button as the final destination Dp, or, if a route to another destination has been set before the second operation, the route Ru may be a route calculated with that other destination as the final destination and the power and hydrogen supply station corresponding to the route guidance button as an intermediate stop.

[0124] Furthermore, when the first operation is performed, the route Ru to the power / hydrogen supply station corresponding to the reservation instruction button may be displayed (not shown).

[0125] The calculations related to the display of the fourth display unit 35d, such as route calculation, may be performed by the control unit of the fourth electric vehicle c4 or by the server 100.

[0126] The hydrogen refueling information may include all power and hydrogen supply stations, but may also include only those within a first distance d1 from the current location of the fourth electric vehicle c4, and / or, if the fourth electric vehicle c4 has set a route, only those within a first distance d1 from that route.

[0127] Furthermore, the hydrogen refueling information may be displayed in order of proximity to the power and hydrogen supply stations, based on the straight-line distance or road distance from the current location of the fourth electric vehicle c4, or, if the fourth electric vehicle c4 has set a route, in order of proximity to the straight-line distance or road distance from that route.

[0128] Furthermore, the hydrogen refueling information may display only those that meet specific conditions, such as hydrogen refueling information corresponding to hydrogen tanks 21d that have been filled with hydrogen among the first to third power and hydrogen supply stations 10a to 10c, hydrogen refueling information corresponding to those for which purchase or exchange reservations are possible, and hydrogen refueling information corresponding to those with a short travel time from the current location.

[0129] (Server 100) Server 100 communicates with the first power and hydrogen supply stations 10a to the third power and hydrogen supply stations 10c, and the first electric vehicle c1 to the fourth electric vehicle c4 via the network. As will be described later, if the server 100 is located adjacent to the first power and hydrogen supply station 10a, the server 100 may be cooled based on the power supplied from the first power and hydrogen supply station 10a (see Figure 10).

[0130] (Operating procedure for load testing) When a load test is performed on the first power generator 11, the second power generator 12 is turned off, and power is supplied from the first power generator 11 to the fixed energy storage unit 17, the portable energy storage unit 18, and the hydrogen generator 21b. When a load test of the second power generator 12 is performed, the first power generator 11 is turned off, and power is supplied from the second power generator 12 to the fixed energy storage unit 17, the portable energy storage unit 18, and the hydrogen generator 21b. When the second power generator 12 is used for purposes other than load testing, the operation is controlled so that power is not supplied from the second power generator 12 to the hydrogen generator 21b. When performing a load test on an external power source under test connected to the first power and hydrogen supply station 10a, the external power source under test is connected to the control device 13, the first power generator 11 and the second power generator 12 are turned off, and power is supplied from the external power source under test to the fixed energy storage unit 17, the portable energy storage unit 18, and the hydrogen generator 21b.

[0131] (Effects of using multiple power generation devices, energy storage devices, and hydrogen storage units) By using the first power generator 11 and the second power generator 12, during the time when the first power generator 11 is able to generate electricity, electricity and hydrogen are stored using the power generated by the first power generator 11. During the time when the first power generator 11 is not able to generate electricity, electricity from the second power generator 12 and the energy storage units (fixed energy storage unit 17, portable energy storage unit 18) is used to drive electrical equipment such as the first load 19a and the first electric vehicle c1. The first power generator 11 generates electricity based on renewable energy, while the second power generator 12 generates electricity based on hydrogen. The hydrogen used in the second power generator 12 is obtained from the hydrogen storage unit 21. Therefore, even without an external power supply, it becomes possible to obtain and store electricity and hydrogen within the first power and hydrogen supply station 10a. The power stored in the energy storage units (fixed energy storage unit 17, portable energy storage unit 18) may decrease due to discharge. The hydrogen stored in the hydrogen tank 21d of the hydrogen storage unit 21 is unlikely to be released spontaneously. Therefore, by using the storage units (fixed storage unit 17, portable storage unit 18) for short-term storage and hydrogen storage in the hydrogen tank 21d for long-term storage, the electricity generated by the first power generator 11 can be efficiently stored. Furthermore, the system supports various forms of supplying electricity and hydrogen to electrical equipment, including direct power supply, direct hydrogen supply, supply of a portable energy storage unit 18, and supply of a hydrogen-containing container (portable hydrogen tank 21d). Furthermore, by using water obtained based on humidity in the air as the electrolyte, it becomes possible to continue accumulating hydrogen even when there is little supply of external components.

[0132] (Effects of using energy storage devices and hydrogen generators as load test areas) Within the first power and hydrogen supply station 10a, it becomes possible to perform load tests on the power generator (first power generator 11, etc.) under both large and small loads using both the power storage device (fixed energy storage unit 17, etc.) and the hydrogen storage device (hydrogen generator 21b, etc.). Since the electricity generated during the load test can be stored as either electricity or hydrogen, there is little energy loss.

[0133] (The effect of using the electrolytic load test area for fine-tuning the load) By controlling the movement of electrolysis electrodes or the supply of electrolyte, it becomes possible to adjust the load amount to a much smaller degree than by switching the number of energy storage devices used in the rechargeable load test area.

[0134] (The effect of being able to adjust the usage priority) Even during periods when the first power generator 11 is unable to generate electricity, power can be supplied using multiple power supply devices, namely the energy storage units (fixed energy storage unit 17, portable energy storage unit 18) and the second power generator 12. On the other hand, it is possible that the power supply devices required and those actually used may not match. By setting an optimal usage priority, it becomes possible to use the stored electricity and hydrogen efficiently.

[0135] (The effect of the control device 13 determining the usage priority based on the usage status of the energy storage unit, etc.) By maintaining a certain level of usage frequency for the fixed energy storage unit 17 and the portable energy storage unit 18, losses due to natural discharge can be reduced. Furthermore, by maintaining a certain level of usage frequency for the second power generation device 12, it is possible to reduce the possibility of deterioration of the second power generation device 12 due to non-use, and the possibility of deterioration of the fixed energy storage unit 17 and the portable energy storage unit 18 due to excessive charging and discharging.

[0136] (Effects of using strain sensors) By using a strain sensor to measure strain as a detection device 21f, the degree of hydrogen filling can be obtained from the degree of strain of the hydrogen storage alloy that has expanded due to absorption. This makes it possible to obtain a more accurate degree of hydrogen filling compared to a method that calculates it based on the flow rate of hydrogen flowing into the hydrogen tank 21d.

[0137] (The effects of directly supplying hydrogen, etc., to electrical equipment) The energy storage unit will be able to supply power via cables to electrical equipment that directly charges the vehicle's battery, such as plug-in hybrid cars (first electric vehicle c1). The hydrogen tank 21d, etc., will be able to supply hydrogen via flexible pipes, etc., to electrical equipment that directly fills the vehicle's fixed in-vehicle hydrogen storage device 31c, such as fuel cell vehicles (third electric vehicle c3).

[0138] (The effect of using the power obtained from load testing) The power obtained from the load test of the power supply under test can be used to store energy in the portable energy storage device 18b and to fill the portable hydrogen tank 21d with hydrogen.

[0139] (The effect of notifying the charging status) In the first electric vehicle c1, which uses electricity stored in the in-vehicle power storage device 31a, it is desirable to be able to obtain information on stores and other places where electricity can be purchased from a fully charged fixed power storage unit 17 or the like. Charging information, including the charging status of the fixed energy storage unit 17, is displayed on the first display unit 35a of the first electric vehicle c1 using the in-vehicle energy storage device 31a. This will make it possible for users of the first electric vehicle c1 to see nearby stores that handle purchasable electricity (electricity and hydrogen supply stations).

[0140] (The effect of providing information on the charging status of multiple power and hydrogen supply stations) By providing information on multiple stores (electricity and hydrogen supply stations) that handle purchasable electricity, it becomes easier for users of the first electric vehicle C1 to choose the most suitable store. By showing the route Ru to the selected store (electricity / hydrogen supply station), it becomes easier to travel to the store.

[0141] (The effect of notifying the charging status) In the second electric vehicle c2 using the portable energy storage device 18b, it is desirable to be able to obtain information about stores where a pre-charged portable energy storage device 18b can be purchased. Charging information, including the charging status of the portable energy storage device 18b, is displayed on the second display unit 35b of the second electric vehicle c2 using the portable energy storage device 18b. This makes it possible for the user of the second electric vehicle c2 to see a store (electricity / hydrogen supply station) that handles portable energy storage devices 18b that can be purchased or exchanged, located near the second electric vehicle c2.

[0142] (The effect of providing information on the charging status of multiple power and hydrogen supply stations) By providing information on multiple stores (electricity and hydrogen supply stations) that handle portable energy storage devices 18b that can be purchased or exchanged, it becomes easier for users of the second electric vehicle c2 to select the most suitable store. By showing the route Ru to the selected store (electricity / hydrogen supply station), it becomes easier to travel to the store.

[0143] (The effect of informing about the hydrogen refueling status) In the third electric vehicle c3, which uses hydrogen stored in an in-vehicle fixed hydrogen storage device 31c, it is desirable to be able to obtain information on stores where hydrogen can be purchased from hydrogen-filled hydrogen tanks 21d, etc. Hydrogen refueling information, including the hydrogen refueling status of the hydrogen tank 21d, is displayed on the third display unit 35c of the third electric vehicle c3, which uses an in-vehicle fixed hydrogen storage device 31c. This will make it possible for users of the third electric vehicle C3 to see nearby stores that handle purchasable electricity (electricity and hydrogen supply stations).

[0144] (The effect of providing information on the charging status of multiple power and hydrogen supply stations) By providing information on multiple locations (electricity and hydrogen supply stations) that handle hydrogen for purchase, it becomes easier for users of the third electric vehicle C3 to choose the most suitable location. By showing the route Ru to the selected store (electricity / hydrogen supply station), it becomes easier to travel to the store.

[0145] (The effect of informing about the hydrogen refueling status) For the fourth electric vehicle C4, which uses hydrogen tank 21d, it would be desirable to be able to obtain information on stores where hydrogen-filled hydrogen tank 21d can be purchased. Hydrogen refueling information, including the hydrogen refueling status of the hydrogen tank 21d, is displayed on the fourth display unit 35d of the fourth electric vehicle c4 that uses the hydrogen tank 21d. This makes it possible for users of the fourth electric vehicle c4 to see stores (electricity and hydrogen supply stations) that handle hydrogen tanks 21d that can be purchased or exchanged near the fourth electric vehicle c4.

[0146] (The effect of providing information on the charging status of multiple power and hydrogen supply stations) By providing information on multiple stores (electricity and hydrogen supply stations) that handle hydrogen tanks 21d that can be purchased or exchanged, it becomes easier for users of the fourth electric vehicle c4 to choose the most suitable store. By showing the route Ru to the selected store (electricity / hydrogen supply station), it becomes easier to travel to the store.

[0147] (The hydrogen generator 21b is not limited to electrolysis.) In the first embodiment, the hydrogen generator 21b was described as a device that generates hydrogen by electrolysis of an electrolyte. However, the method of generating hydrogen is not limited to the electrolysis of an electrolyte. For example, the hydrogen generator 21b may be a device that heats an organic hydride that reversibly releases hydrogen as a catalytic reaction. In this case, an organic hydride supply unit is provided instead of the electrolyte supply unit 21a.

[0148] (Application example of a power and hydrogen supply station, second embodiment) Next, a second embodiment will be described. The first power and hydrogen supply station 10a of the second embodiment differs from the first power and hydrogen supply station 10a of the first embodiment in that the fixed energy storage unit 17 has two energy storage units (first energy storage unit 17a, second energy storage unit 17b), and the hydrogen storage unit 21 has a hydrogen tank 21d and a liquid tank 21i for storing hydrogen as an organic hydride. The following explanation will focus on the differences from the first embodiment. Furthermore, the second power and hydrogen supply station 10b and the third power and hydrogen supply station 10c of the second embodiment may have the same configuration as the first power and hydrogen supply station 10a of the second embodiment.

[0149] (First Electricity / Hydrogen Supply Station 10a) The first power and hydrogen supply station 10a of the second embodiment includes a first power generation device 11, a second power generation device 12, a control device 13, a first converter 13a, a fixed energy storage unit 17, a hydrogen storage unit 21, a switching unit 22, and an input / output terminal unit 24 (see Figure 9). In addition, the first power and hydrogen supply station 10a of the second embodiment may have a charger 14, a station-side display unit 15, a station-side operation unit 16, and a communication unit 23, similar to the first embodiment. The switching unit 22 includes a first switching unit 22a and a second switching unit 22b.

[0150] (First power generator 11) The first power generation device 11 of the second embodiment includes a DC power generator 11a and an AC power generator 11b.

[0151] (DC power generator 11a) The DC power generator 11a is a power generation device (first renewable energy-derived power generator) that generates electricity based on natural energy (renewable energy), such as a solar power generation device or a wind power generation device. The DC power generator 11a is kept in a state where it can generate power at all times. The DC power generator 11a is installed on the rooftop of the building 25 or similar location. The power obtained from the DC power generator 11a is supplied to the first energy storage unit 17a and the second energy storage unit 17b via the first conversion unit 13a1 and the first switching unit 22a.

[0152] (AC power generator 11b) AC power generator 11b is a power generation device (second renewable energy-derived power generation device) that generates electricity based on natural energy (renewable energy), such as a wind power generation device. The AC power generator 11b is kept in a state where it can generate power at all times. However, if the wind force acting on the AC power generator 11b exceeds a predetermined wind force, the AC power generator 11b will be rendered unable to generate power. The AC power generator 11b is installed on the rooftop of the building 25, or similar location. The power obtained from the AC power generator 11b is supplied to the first energy storage unit 17a and the second energy storage unit 17b via the second conversion unit 13a2 and the second switching unit 22b.

[0153] (Second power generator 12) The second power generation device 12 is a power generation device (fuel cell) that generates electricity based on hydrogen. The second power generator 12 is installed inside the building 25 or on the roof of the building 25, etc. The electricity generated by the second power generator 12 is supplied to the second energy storage unit 17b.

[0154] (First converter 13a) The first conversion device 13a of the second embodiment includes a first conversion unit 13a1, a second conversion unit 13a2, a third conversion unit 13a3, a fourth conversion unit 13a4, and a fifth conversion unit 13a5.

[0155] (First conversion unit 13a1) The first conversion unit 13a1 is located between the DC power generator 11a and the first energy storage unit 17a. The first conversion unit 13a1 includes a power conditioner and a DC / DC converter. The power obtained from the DC power generator 11a is converted to a predetermined voltage and current in the first conversion unit 13a1 and supplied to the first energy storage unit 17a or the second energy storage unit 17b.

[0156] (Second conversion unit 13a2) The second conversion unit 13a2 is located between the AC power generator 11b and the first energy storage unit 17a. The second conversion unit 13a2 includes a power conditioner and an AC / DC converter. The power obtained from the AC power generator 11b is converted to a predetermined voltage and current in the second conversion unit 13a2 and supplied to either the first energy storage unit 17a or the second energy storage unit 17b.

[0157] (Third conversion unit 13a3) The third conversion unit 13a3 is provided between the input terminal unit 24a and the first energy storage unit 17a. The third conversion unit 13a3 includes an AC / DC converter. Power from a power supply device (e.g., the second energy storage unit 17b) connected to the input terminal unit 24a is converted to a predetermined voltage and current by the third conversion unit 13a3 and supplied to the first energy storage unit 17a.

[0158] (Fourth conversion unit 13a4) The fourth conversion unit 13a4 is provided between the first energy storage unit 17a and the first output terminal unit 24b1. The fourth conversion unit 13a4 includes a DC / AC inverter. The power stored in the first energy storage unit 17a is converted to a predetermined voltage and current in the fourth conversion unit 13a4 and supplied to electrical equipment (for example, loads within the building 25) connected to the first output terminal unit 24b1.

[0159] (Fifth conversion section 13a5) The fifth conversion unit 13a5 is provided between the second energy storage unit 17b and the second output terminal unit 24b2. The fifth conversion unit 13a5 includes a DC / AC inverter. The power stored in the second energy storage unit 17b is converted to a predetermined voltage and current in the fifth conversion unit 13a5 and supplied to the electrical equipment connected to the second output terminal unit 24b2.

[0160] (Other conversion parts) Furthermore, a conversion unit (such as a DC / DC converter) may be provided between the second power generation device 12 and the second energy storage unit 17b to convert the power obtained by the second power generation device 12 into a predetermined voltage and a predetermined current.

[0161] (Control device 13) The control device 13 controls the operation of each part. The control device 13 is installed inside the building 25, or in a similar location.

[0162] (Control of hydrogen supply to hydrogen tank 21d) For example, if the charge rate R1a of the first energy storage unit 17a is higher than or equal to the full charge threshold Thlf (Thrf>Thr1), and the power P supplied from the first power generation device 11 (DC power generator 11a, AC power generator 11b) is greater than or equal to the power threshold Thp, then the control device 13 assumes that surplus power is being generated and drives the hydrogen storage unit 21. Specifically, the control device 13 drives the hydrogen generator 21b to generate hydrogen. The control device 13 also drives the heating and cooling unit 21c to fill the hydrogen tank 21d with the generated hydrogen.

[0163] (Control of hydrogen supply to liquid tank 21i) If the hydrogen filling rate R3 of the hydrogen tank 21d is higher than or equal to the second hydrogen filling rate threshold Thr4, the control device 13 determines that the hydrogen tank 21d is sufficiently filled with hydrogen and drives the hydrogen addition device 21h to add the generated hydrogen to aromatic compounds such as toluene to produce organic hydrides (saturated condensed ring hydrocarbons) such as methylcyclohexane, which are then stored in the liquid tank 21i. However, hydrogen generated in the hydrogen generator 21b may be supplied to the hydrogen addition device 21h before it is supplied to the hydrogen tank 21d.

[0164] (Control of hydrogen supply to the second power generation device 12) If the hydrogen filling rate R3 of the hydrogen tank 21d is higher than or equal to the second hydrogen filling rate threshold Thr4, and the liquid volume Q of the liquid tank 21i is higher than or equal to the tank capacity threshold Thq, the control device 13 drives the heat retention / cooling unit 21c to supply hydrogen from the hydrogen tank 21d to the second power generation unit 12, and / or drives the dehydrogenation unit 21j to separate hydrogen from the organic hydride in the liquid tank 21i and supply the separated hydrogen to the second power generation unit 12. The control device 13 also drives the second power generation unit 12.

[0165] (Switching control of switching unit 22) However, if the hydrogen filling rate R3 of the hydrogen tank 21d is higher than or equal to the second hydrogen filling rate threshold Thr4, and the liquid volume Q of the liquid tank 21i is higher than or equal to the tank capacity threshold Thq, and the charge rate R1a of the first energy storage unit 17a is higher than or equal to the full charge threshold Thrf, and the power P supplied from the first power generator 11 (DC power generator 11a, AC power generator 11b) is greater than or equal to the power threshold Thp, then the control device 13 drives the first switching unit 22a and the second switching unit 22b to switch the destination of the power supply from the first power generator 11 from the first energy storage unit 17a to the second energy storage unit 17b.

[0166] (Power supply control from the second energy storage unit 17b to the first energy storage unit 17a) Furthermore, if the charge level R1a of the first energy storage unit 17a is lower than the full charge threshold Thrf, and the charge level R1b of the second energy storage unit 17b is higher than or equal to the full charge threshold Thrf, the control device 13 will supply power from the second energy storage unit 17b to the first energy storage unit 17a via the second output terminal 24b2 and the input terminal 24a.

[0167] (Fixed energy storage unit 17) The fixed energy storage unit 17 of the second embodiment has a first energy storage unit 17a and a second energy storage unit 17b.

[0168] (First power storage unit 17a) The first energy storage unit 17a has an energy storage device that stores power from a DC power generator 11a and the like. The first energy storage unit 17a is fixed in a predetermined position in the building 25 without consideration for attachment or detachment. However, the first energy storage unit 17a may be held in a predetermined position in the building 25 in a detachable state.

[0169] The first energy storage unit 17a supplies the stored power to electrical equipment (for example, the first load 19a, etc.) connected to the first output terminal unit 24b1 and to the hydrogen generator 21b.

[0170] (Second power storage unit 17b) The second energy storage unit 17b has an energy storage device that stores power from the DC power generator 11a and the like. Furthermore, the energy storage device of the second energy storage unit 17b stores power from the second power generator 12. Therefore, the second energy storage unit 17b can also be used as an energy storage unit for a fuel cell. The second energy storage unit 17b is fixed in a predetermined position in the building 25 without consideration for attachment or detachment. However, the second energy storage unit 17b may be held in a predetermined position in the building 25 in a detachable state.

[0171] The power stored in the second energy storage unit 17b is supplied to the electrical equipment connected to the second output terminal unit 24b2 (for example, the first load 19a, the input terminal unit 24a, etc.) and the hydrogen generator 21b. However, the power supply from the second energy storage unit 17b to the hydrogen generator 21b may be omitted. The charging capacity of the energy storage device in the first energy storage unit 17a is greater than (approximately three times) the charging capacity of the energy storage device in the second energy storage unit 17b.

[0172] In addition, a portable energy storage unit 18, as described in the first embodiment, may be provided separately from the first energy storage unit 17a and the second energy storage unit 17b. In this case, the portable energy storage unit 18 receives power from at least one of the first energy storage unit 17a and the second energy storage unit 17b.

[0173] (Hydrogen storage unit 21) The hydrogen storage unit 21 of the second embodiment includes an electrolyte supply unit 21a including a water intake unit 21a1, a hydrogen generator 21b, a heat retention / cooling unit 21c, a hydrogen tank 21d, a connecting pipe 21e, a detection device 21f, a hydrogen supply unit 21g, a hydrogen addition device 21h, a liquid tank 21i, and a dehydrogenation device 21j. Of these, the hydrogen tank 21d and the liquid tank 21i function as storage units.

[0174] (Electrolyte supply section 21a) The configuration of the electrolyte supply unit 21a is the same as that of the electrolyte supply unit 21a in the first embodiment. That is, the electrolyte supply unit 21a is provided with a water intake unit 21a1, which is not shown in Figure 9.

[0175] (Hydrogen generator 21b) The hydrogen generator 21b consists of a water electrolysis device and other components, and generates hydrogen by performing electrolysis based on electricity supplied from the DC power generator 11a and other components. The electrolyte supply unit 21a and the hydrogen generator 21b may be configured as separate units or as an integrated unit.

[0176] The hydrogen generator 21b is connected to the second power generator 12, the hydrogen tank 21d, the hydrogen supply unit 21g, the hydrogen addition device 21h, and the hydrogen supply unit 21g via a connecting pipe 21e. The connecting pipe 21e is equipped with a valve (flow rate control device for the connecting pipe 21e) that controls the flow of hydrogen, such as the amount of hydrogen supplied from the hydrogen generator 21b. Figure 9 shows an example in which the connecting pipe 21e is equipped with an 11th valve b1 between the hydrogen generator 21b and the hydrogen addition device 21h, a 12th valve b2 between the hydrogen generator 21b and the hydrogen supply unit 21g, a 13th valve b3 between the hydrogen generator 21b and the dehydrogenation device 21j, a 14th valve b4 between the hydrogen generator 21b and the hydrogen tank 21d, and a 15th valve b5 between the second power generation device 12 and the hydrogen generator 21b. The valves (11th valve b1 to 15th valve b5) of the connecting pipe 21e function as a flow rate control device (first flow rate control device) for the connecting pipe 21e, controlling the amount of hydrogen supplied by the hydrogen generator 21b. However, the first flow rate control device may be composed of other components. When supplying hydrogen from the hydrogen generator 21b to the hydrogen addition device 21h, the 11th valve b1 in the connecting pipe 21e is opened, and the other valves (12th valve b2 to 15th valve b5) are closed. The opening and closing of the valves (11th valve b1 to 15th valve b5) installed in the connecting pipe 21e are performed electrically, for example, by control by the control device 13.

[0177] (Thermal insulation cooling part 21c) The configuration of the heat retention and cooling section 21c is the same as that of the heat retention and cooling section 21c in the first embodiment.

[0178] (Hydrogen tank 21d) The configuration of the hydrogen tank 21d is the same as that of the hydrogen tank 21d in the first embodiment. In the second embodiment, an example is shown in which only one hydrogen tank 21d is provided, but as in the first embodiment, multiple hydrogen tanks 21d may be provided. Although not shown in Figure 9, etc., a buffer tank 21d1 and a pressure reducing device 21d2 may also be provided. The configuration of the detection device 21f is the same as that of the detection device 21f in the first embodiment.

[0179] (Hydrogen supply unit 21g) The hydrogen supply unit 21g is connected to the third electric vehicle c3 in a detachable manner, similar to the hydrogen supply unit 21g in the first embodiment, and supplies hydrogen from the hydrogen tank 21d or the like to the in-vehicle fixed hydrogen storage device 31c of the third electric vehicle c3. Furthermore, similar to the first embodiment, a high-pressure hydrogen tank or the like may be connected to the hydrogen supply unit 21g in a detachable manner. In this case, hydrogen from the high-pressure hydrogen tank or the like may be supplied to the hydrogen tank 21d or the like.

[0180] (Hydrogen addition device 21h) The hydrogenation device 21h produces an organic hydride by adding hydrogen to an aromatic compound in a hydrogenation reaction. The catalyst used to activate the hydrogenation reaction (first catalyst 21h1, see Figure 13) is heated by a catalyst heating device for the hydrogenation reaction. However, as shown in the fourth embodiment described later, the first catalyst 21h1 may also be heated using heat obtained from a device other than the catalyst heating device for the hydrogenation reaction, such as a solar water heater 20.

[0181] (Liquid Tank 21i) Liquid tank 21i stores the organic hydride produced in the hydrogenation unit 21h. The liquid tank 21i is equipped with a liquid volume detection device (not shown) that detects the liquid volume Q in the tank.

[0182] (Dehydrogenator 21j) The dehydrogenation apparatus 21j separates hydrogen from the organic hydride in a dehydrogenation reaction. The catalyst used to activate the dehydrogenation reaction (second catalyst 21j1, see Figure 13) is heated by a catalyst heating device for the dehydrogenation reaction (not shown). However, as shown in the fourth embodiment described later, the second catalyst 21j1 may also be heated using heat obtained from a device other than the catalyst heating device for the dehydrogenation reaction, such as a solar water heater 20.

[0183] (Aromatic compound tank) The hydrogen storage section is equipped with a tank (not shown) for storing aromatic compounds to be supplied to the hydrogenation unit 21h, and a tank (not shown) for storing aromatic compounds that have been purified by the separation of hydrogen in the dehydrogenation unit 21j.

[0184] The material to which hydrogen is added (hydrogenated material) is not limited to aromatic compounds; it may also be an aldehyde, ketone, or the like.

[0185] (Switching section 22) The switching unit 22 of the second embodiment has a first switching unit 22a and a second switching unit 22b.

[0186] (First switching section 22a) The first switching unit 22a switches the destination of the power supply from the DC power generator 11a between the first energy storage unit 17a and the second energy storage unit 17b.

[0187] (Second switching section 22b) The second switching unit 22b switches the destination of the power supply from the AC power generator 11b between the first energy storage unit 17a and the second energy storage unit 17b.

[0188] (Switching control) Normally, power from the DC power generator 11a is supplied to the first power storage unit 17a via the first conversion unit 13a1 and the first switching unit 22a, and power from the AC power generator 11b is supplied to the first power storage unit 17a via the second conversion unit 13a2 and the second switching unit 22b. However, when the first power storage unit 17a is in a fully charged state and the degree of hydrogen filling in the subsequent hydrogen tank 21d and liquid tank 21i is high, power from the DC power generator 11a is supplied to the second power storage unit 17b via the first conversion unit 13a1 and the first switching unit 22a, and power from the AC power generator 11b is supplied to the second power storage unit 17b via the second conversion unit 13a2 and the second switching unit 22b.

[0189] Specifically, when the hydrogen filling rate R3 of the hydrogen tank 21d is higher than the second hydrogen filling rate threshold value Thr4, the liquid volume Q of the liquid tank 21i is higher than the tank capacity threshold value Thq, the charging rate R1a of the first power storage unit 17a is higher than the full charge threshold value Thrf, and the power P supplied from the first power generator 11 is more than the power threshold value Thp, the supply destination of the power from the first power generator 11 is switched from the first power storage unit 17a to the second power storage unit 17b.

[0190] (Input / output terminal unit 24) The input / output terminal unit 24 includes an input terminal unit 24a, a first output terminal unit 24b1, and a second output terminal unit 24b2.

[0191] (Input terminal unit 24a) The input terminal unit 24a is detachably connected to an external power source (e.g., commercial power source) or an internal power source (second power storage unit 17b). Power from the external power source connected to the input terminal unit 24a is supplied to the first power storage unit 17a via the input terminal unit 24a and the third conversion unit 13a3. Note that the input terminal unit 24a may be connected to the second output terminal unit 24b2 via a cable. FIG. 9 shows an example in which the input terminal unit 24a is connected to the second output terminal unit 24b2 via a cable. The input terminal section 24a may be connected to the first electric vehicle c1 as an external power source. In this case, the third conversion section 13a3 and the input terminal section 24a function as the second converter 14b of the charger 14 described in the first embodiment.

[0192] (1st output terminal section 24b1) The first output terminal 24b1 is connected to an external electrical device (e.g., a first electric vehicle c1) or an internal electrical device (e.g., a first load 19a). Power from the first energy storage unit 17a is supplied to the electrical equipment connected to the first output terminal unit 24b1 via the fourth conversion unit 13a4 and the first output terminal unit 24b1. When the first output terminal section 24b1 is connected to the first electric vehicle c1, the fourth conversion section 13a4 and the first output terminal section 24b1 function as the first converter 14a of the charger 14 described in the first embodiment. Note that power supply from the first energy storage unit 17a to internal electrical equipment such as the first load 19a may be performed without going through the first output terminal unit 24b1. In this case, power from the first energy storage unit 17a is supplied to the first load 19a, etc., via the fourth conversion unit 13a4.

[0193] (Second output terminal section 24b2) The second output terminal section 24b2 is connected to an external electrical device (for example, a first electric vehicle c1) or an internal electrical device (for example, a first load 19a). The power from the second energy storage unit 17b is connected to the electrical equipment connected to the second output terminal unit 24b2 via the fifth conversion unit 13a5 and the second output terminal unit 24b2. The second output terminal 24b2 may be connected to the input terminal 24a via a cable. When the second output terminal section 24b2 is connected to the first electric vehicle c1, the fifth conversion section 13a5 and the second output terminal section 24b2 function as the charger 14 described in the first embodiment. In addition, power supply from the second energy storage unit 17b to internal electrical equipment such as the first load 19a may be performed without going through the second output terminal unit 24b2. In this case, power from the second energy storage unit 17b is supplied to the first load 19a, etc., via the fifth conversion unit 13a5.

[0194] (Building 25) Building 25 is a building equipped with the first load 19a, etc., similar to the first embodiment. The second power generator 12, the first energy storage unit 17a, the second energy storage unit 17b, the hydrogen generator 21b, the hydrogen tank 21d, the hydrogen addition device 21h, the liquid tank 21i, the dehydrogenation device 21j, etc., are located inside the building 25.

[0195] (Effects of providing the first energy storage unit 17a, the second energy storage unit 17b, and the hydrogen storage unit 21) Power from the first energy storage unit 17a is supplied to the hydrogen generator 21b. The hydrogen produced by the hydrogen generator 21b is stored in the storage section (hydrogen tank 21d, liquid tank 21i) and used for power generation by the second power generator 12. The power generated by the second power generator 12 is not supplied directly to the first energy storage unit 17a, but is supplied to the second energy storage unit 17b, and then, after conversion from DC to AC and from AC to DC via the fifth conversion unit 13a5 and the like, it is supplied to the first energy storage unit 17a. Therefore, compared to a configuration in which the power obtained from the second power generator 12 is directly supplied to the first energy storage unit 17a, it is possible to easily control (voltage, current, timing, etc.) the power to be returned to the first energy storage unit 17a.

[0196] (The effect of installing two types of hydrogen storage devices) A device that stores energy obtained from the first power generation device 11 and other sources as electricity (first energy storage unit 17a, second energy storage unit 17b) and a device that stores energy as hydrogen (hydrogen tank 21d, liquid tank 21i) are used in combination. Therefore, even when the first energy storage unit 17a and other components are fully charged, it becomes possible to convert excess power into hydrogen and store a large amount of energy. Furthermore, if the power supply from the first power generator 11 is insufficient, and the power stored in the first energy storage unit 17a, etc., is also insufficient, the hydrogen in the storage unit (hydrogen tank 21d, liquid tank 21i) can be converted into electricity to supply power to electrical equipment such as the first load 19a. The storage unit for accumulating hydrogen can have its capacity increased relatively easily compared to batteries and other devices that store electricity. Therefore, surplus electricity can be easily stored as hydrogen using storage units (hydrogen tank 21d, liquid tank 21i) of appropriate size based on the difference between the power obtained from the first power generator 11 and the power required by electrical equipment such as the first load 19a. Furthermore, it can not only supply power to external devices but also supply hydrogen.

[0197] (Effects of controlling energy storage and hydrogen storage) Depending on the charge levels of the first energy storage unit 17a and the second energy storage unit 17b, the hydrogen filling level of the hydrogen tank 21d, and the liquid volume of the liquid tank 21i, it becomes possible to control charging, hydrogen generation, hydrogen storage, and hydrogen-based power generation.

[0198] In the second embodiment, a photovoltaic power generation device having a power generation capacity of 1.5 kW is used as the DC power generation device 11a. Furthermore, a wind power generator with a power generation capacity of 300W is used as the AC power generator 11b. Furthermore, as the second power generation device 12, a fuel cell with a rated output power of 3kW, a rated output voltage of DC48V, a hydrogen supply capacity of 2670SL (Standard Litter) / h, and a hydrogen pressure of 0.06~0.07MPa is used. Furthermore, a DC / DC converter with an output voltage of 48V is used as the first conversion unit 13a1. Furthermore, an AC / DC converter with an output voltage of 48V is used as the second conversion unit 13a2. Furthermore, as the third conversion unit 13a3, an AC / DC converter is used with an input voltage of three-phase 200V, an input power of 3kW to 7.5kW, and an output power of 15kWh or less. In addition, as the fourth conversion unit 13a4, a DC / AC inverter with an output voltage of three-phase 200V and an output power of 12kW is used. In addition, as the fifth conversion unit 13a5, a DC / AC inverter with an output voltage of three-phase 200V and an output power of 3kW is used. In addition, as the first power storage unit 17a, a lithium-ion battery with a voltage of 48V and an electric energy of 5kWh, in which three are connected in series or parallel, is used. In addition, as the second power storage unit 17b, a lithium-ion battery with a voltage of 48V and an electric energy of 5kWh, in which one is provided, is used. In addition, as the hydrogen generation device 21b, a water electrolysis device with a hydrogen generation amount of 183NL / h, a hydrogen pressure of 0.45MPa, an electrolysis voltage of DC48V, a supply power of 1500W, and an input voltage of DC48V is used. In addition, as the hydrogen tank 21d, a hydrogen storage alloy container with a capacity of 10000NL is used.

[0199] In this case, with one first power and hydrogen supply station 10a, power supply to one apartment building or the like can be performed independently without power supply from a commercial power source. Also, since the numerical values of the specifications (capacity, pressure, etc.) of each part are relatively small, compared with the form in which the numerical values of the specifications of each part are large, the application to each institution when installing the hydrogen tank 21d or the like in the building 25 is simple. However, the numerical values such as the capacity of each part are just examples and are not limited to these.

[0200] Next, an example of cooling the server 100 based on the power from the first power and hydrogen supply station 10a will be described (see the third embodiment and FIG. 10). In the third embodiment, an example is shown in which power is supplied from the first output terminal portion 24b1 of the first power and hydrogen supply station 10a to the heat exchange portion 130 or the like. However, power may be supplied from the second output terminal portion 24b2 of the first power and hydrogen supply station 10a to the heat exchange portion 130 or the like.

[0201] The first power and hydrogen supply station 10a of the third embodiment includes a first power generation device 11, a second power generation device 12, a control device 13, a first converter 13a, a fixed energy storage unit 17, a hydrogen storage unit 21, a switching unit 22, and an input / output terminal unit 24. In the third embodiment, the first power and hydrogen supply station 10a is connected to a heat transfer medium circulation device (liquid tank 110, liquid delivery unit 120, heat exchange unit 130, switching device 140). In the third embodiment, the first power and hydrogen supply station 10a and the heat transfer medium circulation device constitute a cooling device for cooling a computer such as a server 100.

[0202] Furthermore, the configuration of the first power generation device 11, second power generation device 12, control device 13, first converter 13a, fixed energy storage unit 17, hydrogen storage unit 21, switching unit 22, and input / output terminal unit 24 in the third embodiment is the same as that of the first power generation device 11, second power generation device 12, control device 13, first converter 13a, fixed energy storage unit 17, hydrogen storage unit 21, switching unit 22, and input / output terminal unit 24 in the second embodiment.

[0203] The following will explain the differences from the second embodiment, focusing on the configuration of the heat transfer medium circulation device. In addition, the first power and hydrogen supply station 10a of the third embodiment may have a charger 14, a station-side display unit 15, a station-side operation unit 16, and a communication unit 23, similar to the first embodiment. Furthermore, the second power and hydrogen supply station 10b and the third power and hydrogen supply station 10c of the third embodiment may have the same configuration as the first power and hydrogen supply station 10a of the third embodiment.

[0204] (liquid tank 110) The liquid tank 110 holds at least the heat-generating components (CPU, storage, etc.) of a computer such as a server 100 in a state where they are immersed in the first heat transfer medium. In other words, the liquid tank 110 holds the computer and the first heat transfer medium (cooling solution) for cooling the computer. The first heat transfer medium consists of an insulating liquid, such as a fluorinated inert liquid or pure water.

[0205] (Liquid transport section 120) The liquid transfer unit 120 includes a pump, compressor, etc., and is used to circulate the first heat transfer medium between the liquid tank 110 and the heat exchange unit 130.

[0206] (Heat exchange part 130) The heat exchange unit 130 includes a fan 130a, a spray unit 130b, etc., and cools the first heat transfer medium from the liquid tank 110 by heat exchange. Fan 130a supplies cooling air to the tube through which the high-temperature first heat transfer medium passes. The spray unit 130b sprays mist-like cooling water onto at least one of the pipe through which the high-temperature first heat transfer medium passes and the fan 130a. However, the heat exchange unit 130 may be configured to cool the first heat transfer medium using a cooling tower or the like, instead of a fan 130a, by using a refrigerant such as water.

[0207] The liquid tank 110, liquid supply unit 120, and heat exchange unit 130 constitute a heat transfer medium circulation device (chiller) for cooling the server 100.

[0208] (Switching device 140) Server 100 is connected to the commercial power supply and the first output terminal section 24b1 via the switching device 140. The switching device 140 normally supplies power to the server 100 from the commercial power supply, and when the power supply from the commercial power supply is interrupted, it performs timing synchronization and switches the power supply so that power from the first output terminal 24b1 is supplied to the server 100.

[0209] (The effect of a cooling device, including the liquid transfer unit 120, performing cooling of the server 100, etc.) Since a liquid is used as the first heat transfer medium, it becomes possible to cool the server 100 more efficiently compared to cooling methods that use gases such as air. Cooling using a heat transfer medium circulation is performed based on electricity from two types of power generation devices (first power generation device 11, second power generation device 12). Therefore, compared to a system where cooling using a heat transfer medium circulation is performed based on electricity from the commercial power supply, the possibility of a cooling failure due to a power outage or other interruption of power supply from the commercial power supply can be reduced.

[0210] (Cooling effect using spray unit 130b) By spraying the mist-like cooling water from the spray unit 130b into the pipe through which the first heat transfer medium passes, it becomes possible to perform cooling using the heat of vaporization.

[0211] (Effects of supplying power to the server 100, etc., via the switching device 140) For computers such as server 100, which normally operate based on power from the commercial power supply, it becomes possible to maintain the operation of the computer using the power from the first energy storage unit 17a, etc., even when the power supply from the commercial power supply is interrupted, such as in a power outage.

[0212] Furthermore, the objects to be cooled by the heat transfer medium circulation device of the third embodiment are not limited to the server 100 of the power and hydrogen supply system 1, that is, the server 100 that communicates with the first power and hydrogen supply stations 10a to the third power and hydrogen supply stations 10c and the first electric vehicle c1 to the fourth electric vehicle c4 via the network. The heat transfer medium circulation device of the third embodiment may also be used to cool a server or computer other than the power and hydrogen supply system 1.

[0213] (Examples of applications for the arrangement of heat transfer fluid circulation systems) In the third embodiment, an example was described in which the heat transfer medium circulation device, including the heat exchange unit 130, is configured separately from the first power and hydrogen supply station 10a. However, the components constituting the first power and hydrogen supply station 10a (other than the first power generator 11) and the components constituting the heat transfer medium circulation device may be provided inside a single enclosure 25 (for example, a 20-foot container) (see Figure 11). In this case as well, the first power generator 11 is placed on the top surface of the enclosure or the like. In this case, by carrying the single enclosure 25, the server 100 can be operated in various locations without relying on external power supply such as commercial power.

[0214] (Application example of power and hydrogen supply station, fourth embodiment) Next, a fourth embodiment will be described. The first power and hydrogen supply station 10a of the fourth embodiment differs from the first power and hydrogen supply station 10a of the third embodiment in that it has a solar water heater 20. Furthermore, heat is supplied from heat-generating parts such as the solar water heater 20 to parts that require heat, such as the hydrogen tank 21d. The following explanation will focus on the differences from the third embodiment.

[0215] The first power and hydrogen supply station 10a of the fourth embodiment includes a first power generation device 11, a second power generation device 12, a control device 13, a first converter 13a, a fixed energy storage unit 17, a solar water heater 20, a hydrogen storage unit 21, a switching unit 22, and an input / output terminal unit 24 (see Figure 12). In the fourth embodiment, the first power and hydrogen supply station 10a is connected to a heat transfer medium circulation device (liquid tank 110, liquid delivery unit 120, heat exchange unit 130, switching device 140). Similar to the third embodiment, the first power and hydrogen supply station 10a and the heat transfer medium circulation device may be configured as separate units or may be configured inside a single housing 25.

[0216] Furthermore, the configuration of the first power generation device 11, second power generation device 12, control device 13, first converter 13a, fixed energy storage unit 17, hydrogen storage unit 21, switching unit 22, input / output terminal unit 24, building 25, server 100, liquid tank 110, liquid transfer unit 120, heat exchange unit 130, and switching device 140 in the fourth embodiment is the same as that of the first power generation device 11, second power generation device 12, control device 13, first converter 13a, fixed energy storage unit 17, hydrogen storage unit 21, switching unit 22, input / output terminal unit 24, building 25, server 100, liquid tank 110, liquid transfer unit 120, heat exchange unit 130, and switching device 140 in the third embodiment.

[0217] Furthermore, the first power and hydrogen supply station 10a of the fourth embodiment may also have a charger 14, a station-side display unit 15, a station-side operation unit 16, and a communication unit 23, similar to the first embodiment. Furthermore, the second power and hydrogen supply station 10b and the third power and hydrogen supply station 10c of the fourth embodiment may have the same configuration as the first power and hydrogen supply station 10a of the fourth embodiment. Furthermore, in the fourth embodiment, an example is shown in which power is supplied to the heat exchange unit 130 and the like from the first output terminal 24b1 of the first power and hydrogen supply station 10a. However, power may be supplied to the heat exchange unit 130 and the like from the second output terminal 24b2 of the first power and hydrogen supply station 10a.

[0218] (Solar water heater 20) The solar water heater 20 is a device that heats cold water using solar heat, and includes a solar collector that collects solar heat to produce hot water, and a hot water storage tank that stores the hot water produced by the solar collector. The solar water heater 20's collector is installed on the upper part of the building 25, etc.

[0219] The water obtained at the water intake section 21a1 is supplied to the solar water heater 20 either via the electrolyte supply section 21a or directly without going through the electrolyte supply section 21a. The hot water in the storage tank of the solar water heater 20 (hot water obtained from the solar water heater 20) is supplied to the hydrogen generator 21b. Therefore, in the fourth embodiment, hot water is supplied to the hydrogen generator 21b instead of cold water.

[0220] By using hot water, it becomes possible to increase the reaction rate of electrolysis and reduce the power consumption required to obtain the desired hydrogen, compared to using cold water. Furthermore, the hot water obtained from the solar water heater 20 may be used not only for supplying to the hydrogen generator 21b, but also for showers, etc.

[0221] When moisture in the air is condensed and the condensed water is heated by the solar water heater 20, it becomes possible to operate each part of the first power and hydrogen supply station 10a with minimal reliance on the supply of a second heat transfer medium from an external source.

[0222] Furthermore, the hot water in the storage tank of the solar water heater 20 (hot water obtained from the solar water heater 20), or the heat transferred from said hot water, is supplied to components in the first power and hydrogen supply station 10a that require heating (hydrogen tank 21d, catalyst of hydrogen addition device 21h, catalyst of dehydrogenation device 21j). In other words, the heat from the hot water obtained from the solar water heater 20 is used to release the hydrogen stored in the hydrogen tank 21d. Furthermore, the heat from the hot water obtained from the solar water heater 20 is used to heat the catalyst in at least one of the hydrogenation unit 21h and the dehydrogenation unit 21j. Details regarding the transfer of heat obtained from the solar water heater 200 to the hydrogen tank 21d and other components will be described later.

[0223] This makes it possible to reduce the energy consumption of other heating devices, such as the heat retention and cooling section 21c, compared to a configuration that does not use the heat from the hot water obtained by the solar water heater 20.

[0224] (Timing of heat supply) When the power supplied from the DC power generator (photovoltaic power generator) 11a of the first power generation device 11 is less than the power threshold Thp, it is desirable that the heat generated during power generation by the second power generation device 12 be used to release the hydrogen stored in the hydrogen tank 21d. When the power supplied from the DC power generator (photovoltaic power generator) 11a of the first power generation device 11 is greater than or equal to the power threshold Thp, it is desirable that the heat from the hot water obtained from the solar water heater 20 be mainly used to release the hydrogen stored in the hydrogen tank 21d.

[0225] As a result, during the time periods when hot water can be generated using the solar water heater 20, the second power generation device 12 can be used as much as possible without using the second power generation device 12, thereby reducing the load on the second power generation device 12 and conserving the hydrogen stored in the liquid tank 21i.

[0226] (Examples of applications for heat supply sources) The supply of heat to components requiring heating at the first power and hydrogen supply station 10a (hydrogen tank 21d, catalyst for hydrogen addition device 21h, catalyst for dehydrogenation device 21j) is not limited to using hot water obtained from the solar water heater 20. For example, at least one of the heat generated during power generation in the second power generation device 12, the heat generated during the hydrogenation reaction in the hydrogenation device 21h, and the heat obtained in the heat exchange unit 130 may be used. In this case, the release of hydrogen stored in the hydrogen tank 21d utilizes at least one of the following: the heat generated during power generation by the second power generator 12, the heat from the hot water obtained by the solar water heater 20, the heat generated during the hydrogenation reaction in the hydrogenation device 21h, and the heat obtained by the heat exchange unit 130. Details regarding the transfer of heat generated during power generation by the second power generator 12 to the hydrogen tank 21d and other components will be described later.

[0227] (Examples of applications of heat-utilizing components) Furthermore, the heat generated during power generation by the second power generation device 12 may be used to heat the catalyst in at least one of the hydrogenation device 21h and the dehydrogenation device 21j.

[0228] (Specific examples of heat transfer structures) The following describes a configuration in which the heat generated during power generation by the second power generation device 12, the heat obtained from the solar water heater 20, the heat generated during the hydrogenation reaction in the hydrogenation device 21h, and the heat obtained from the heat exchange unit 130 are supplied to the hydrogen generator 21b and the like (see Figure 13).

[0229] The second heat transfer medium (hot water), heated by the heat generated during power generation in the second power generation device 12, the heat obtained in the solar water heater 20, the heat generated during the hydrogenation reaction in the hydrogenation device 21h, and the heat obtained in the heat exchange unit 130, is supplied to the hydrogen generator 21b and the like via the circulation path 200.

[0230] (Circulation route 200) The circulation path 200 is equipped with a pump 210 and valves 1 through 8 (valves 221 through 228). To supply the second heat transfer medium, the electrolyte supply unit 21a is connected to the circulation path 200. Pump 210 and valves 221 to 228 function as a flow control device (second flow control device) for the circulation path 200. However, the second flow control device may be composed of other components.

[0231] (Pump 210) Pump 210 circulates hot water inside the circulation path 200.

[0232] (Valve 1, 221) The first valve 221 is installed between the solar water heater 20 and the circulation path 200. The first valve 221 controls at least one of the supply of the second heat transfer medium to the solar water heater 20 and the discharge of the second heat transfer medium from the solar water heater 200. During the daytime, when the solar water heater 20 is generating hot water, the first valve 221 is kept open, and at night, when the solar water heater 20 is not generating hot water, the first valve 221 is kept closed.

[0233] (Valve 222) The second valve 222 is located between the second power generator 12 and the circulation path 200. The second valve 222 controls the passage of the second heat transfer medium to the vicinity of the heat-generating region in the second power generator 12. When the second power generator 12 is generating power, the second valve 222 is in an open state, and when it is not generating power, the second valve 222 is in a closed state. The water discharged during power generation in the second power generation device 12 is supplied to the electrolyte supply unit 21a. The discharged water to the electrolyte supply unit 21a may be supplied via the circulation path 200, or via another flow path (see dashed arrow in Figure 13).

[0234] (3rd valve 223) The third valve 223 is located between the hydrogenation device 21h and the circulation path 200. The third valve 223 controls the passage of the second heat transfer medium to the vicinity of the heat-generating region in the hydrogenation device 21h. When the hydrogenation device 21h is performing a hydrogenation reaction, the third valve 223 is in an open state, and when the hydrogenation reaction is not performing, the third valve 223 is in a closed state.

[0235] (Valve 4, 224) The fourth valve 224 is located between the hydrogenation device 21h and the circulation path 200. The fourth valve 224 controls the passage of the second heat transfer medium to the vicinity of the first catalyst 21h1 in order to heat the first catalyst 21h1 in the hydrogenation unit 21h. In the stage before the hydrogenation reaction in the hydrogenation device 21h is activated, when the second heat transfer medium in the circulation path 200 is above a predetermined temperature, the fourth valve 224 is opened, and at other times, the fourth valve 224 is closed. However, while the hydrogenation reaction is taking place, the catalyst in the hydrogenation device 21h is also likely to be at a high temperature, and the fourth valve 224 may be kept open.

[0236] (5th valve 225) The fifth valve 225 is located between the heat exchange section 130 and the circulation path 200. The fifth valve 225 controls the passage of the second heat transfer medium into the region of the heat exchange section 130 that is in contact with the area where the first heat transfer medium from the liquid tank 110 passes, prior to the cooling by the spray section 130b. When server 100 is running, the fifth valve 225 is in the open position, and when server 100 is not running, the fifth valve 225 is in the closed position. The second heat transfer medium also functions as a coolant for the first heat transfer medium.

[0237] (Valve 6, 226) The sixth valve 226 is located between the dehydrogenation unit 21j and the circulation path 200. The sixth valve 226 controls the passage of the second heat transfer medium to the vicinity of the second catalyst 21j1 in order to heat the second catalyst 21j1 in the dehydrogenation unit 21j. In the pre-activation stage of the dehydrogenation reaction in the dehydrogenation unit 21j, when the second heat transfer medium in the circulation path 200 is above a predetermined temperature, the sixth valve 226 is opened, and at all other times, the sixth valve 226 is closed.

[0238] (Valve 7, 227) The seventh valve 227 is located between the hydrogen tank 21d and the circulation path 200. The seventh valve 227 controls the passage of the second heat transfer medium to the vicinity of the hydrogen tank 21d in order to heat the hydrogen tank 21d. When releasing hydrogen stored in the hydrogen tank 21d, the seventh valve 227 is opened, and when not releasing hydrogen stored in the hydrogen tank 21d, the seventh valve 227 is closed.

[0239] (8th valve 228) The eighth valve 228 is located between the hydrogen generator 21b and the circulation path 200. The eighth valve 228 controls the supply of the second heat transfer medium to the hydrogen generator 21b in order to supply the second heat transfer medium to the hydrogen generator 21b. When hydrogen is generated in the hydrogen generator 21b, the eighth valve 228 is opened, and when hydrogen is not generated in the hydrogen generator 21b, the eighth valve 228 is closed. Moisture (such as drain water) contained in the gas from the hydrogen generator 21b, hydrogen tank 21d, and connecting pipe 21e is supplied to the electrolyte supply unit 21a. The supply of moisture contained in the gas to the electrolyte supply unit 21a may be carried out via the circulation path 200 or via another flow path (see dashed arrow in Figure 13).

[0240] (The main entity controlling the motion) The control device 13 controls the operation of the pump 210 and the opening and closing of the first valve 221 to the eighth valve 228 according to the operating status of the station-side operating unit 16.

[0241] Furthermore, a heat transfer device (such as a Peltier element) may be provided between the heat-generating device, such as the second power generator 12, and the circulation path 200, which can be electrically controlled to transfer heat to the circulation path 200 when necessary. Furthermore, a heat transfer device may be provided between the heat-receiving device, such as the hydrogen tank 21d, and the circulation path 200, which can be electrically controlled to transfer heat from the circulation path 200 when necessary. Alternatively, a heat transfer device may be provided between a heat-generating device such as the second power generator 12 and a heat-receiving device such as the hydrogen tank 21d, without providing a circulation path 200.

[0242] Figure 14 shows an example in which heat transfer devices (first heat transfer device 231 to sixth heat transfer device 236) are installed in place of the second valve 222 to the seventh valve 227. The first heat transfer device 231 is installed between the region where heat is generated in the second power generation device 12 and the circulation path 200. The second heat transfer device 232 is located between the region where heat is generated in the hydrogenation device 21h and the circulation path 200. The third heat transfer device 233 is installed between the first catalyst 21h1 and the circulation path 200 in the hydrogenation device 21h. The fourth heat transfer device 234 is a pipe through which the first heat transfer medium from the liquid tank 110 in the heat exchange section 130 passes, and is installed between the section before cooling by the spray section 130b takes place and the circulation path 200. The fifth heat transfer device 235 is installed between the second catalyst 21j1 and the circulation path 200 in the dehydrogenation device 21j. The sixth heat transfer device 236 is installed between the hydrogen tank 21d and the circulation path 200.

[0243] (Examples of applications using auxiliary power) In the fourth embodiment, power is supplied to the electrical equipment constituting the first power and hydrogen supply station 10a, such as the control device 13, the water intake unit 21a1, the flow rate control device for the connecting pipe 21e (e.g., the 11th valve b1 of the connecting pipe 21e), and the flow rate control device for the circulation path 200 (e.g., the pump 210, the first valve 221), from the first energy storage unit 17a or the second energy storage unit 17b. However, a third energy storage unit 17c separate from the first energy storage unit 17a and the second energy storage unit 17b may also be provided (see Figure 15).

[0244] The third energy storage unit 17c supplies power to the electrical equipment constituting the first power and hydrogen supply station 10a as an auxiliary power source. In this case, the switching unit 22 has a first switching unit 22a, a second switching unit 22b, and a third switching unit 22c. The third switching unit 22c switches the destination of the power supplied from the DC power generator 11a between the third energy storage unit 17c and the fifth conversion unit 13a5 (or the second energy storage unit 17b).

[0245] The power obtained from the DC power generator 11a is supplied to the third energy storage unit 17c via the first conversion unit 13a1, the first switching unit 22a, and the third switching unit 22c. However, the power supply to the third energy storage unit 17c may be performed from either the first energy storage unit 17a or the second energy storage unit 17b. Although the connections are not shown in Figure 15, the power obtained from the AC power generator 11b or power from an external power source connected to the input terminal unit 24a may also be supplied to the third energy storage unit 17c.

[0246] The charging capacity of the energy storage device in the second energy storage unit 17b is greater than the charging capacity of the energy storage device in the third energy storage unit 17c. For example, the first energy storage unit 17a uses a lithium-ion battery with a voltage of 48V and an energy capacity of 15kWh, the second energy storage unit 17b uses a lithium-ion battery with a voltage of 48V and an energy capacity of 10kWh, and the third energy storage unit 17c uses a lithium-ion battery with a voltage of 48V and an energy capacity of 4.8kWh.

[0247] (Examples of applications of power output) In the fourth embodiment, when power from the DC power generator 11a is output from the second output terminal 24b2, the power from the DC power generator 11a is first stored in the second energy storage unit 17b, and then output from the second output terminal 24b2. However, as shown in Figure 15, the power from the DC power generator 11a may be output via the first conversion unit 13a1, the first switching unit 22a, the third switching unit 22c, the fifth conversion unit 13a5, and the second output terminal 24b2 without going through the second energy storage unit 17b.

[0248] Furthermore, when power from the AC power generator 11b is output from the second output terminal 24b2, the power from the AC power generator 11b is first stored in the second energy storage unit 17b, and then output from the second output terminal 24b2. However, as shown in Figure 15, the power from the AC power generator 11b may be output via the second conversion unit 13a2, the second switching unit 22b, the fifth conversion unit 13a5, and the second output terminal 24b2 without going through the second energy storage unit 17b.

[0249] (Two enclosures) The components constituting the first power and hydrogen supply station 10a may be housed in one enclosure (building 25), or they may be housed in two enclosures (first enclosure 25a, second enclosure 25b). For example, the first enclosure 25a includes a DC power generator 11a, an AC power generator 11b, and a first energy storage unit 17a (the area to the upper right of the dotted line in Figure 15). The second enclosure 25b includes a second power generator 12, a second energy storage unit 17b, a third energy storage unit 17c, a solar water heater 20, and a hydrogen storage unit 21.

[0250] (Effects of supplying power to the first flow control device (such as the 11th valve b1 of the connecting pipe 21e) with an auxiliary power source (3rd energy storage unit 17c) separate from the fuel cell energy storage unit (2nd energy storage unit 17b)) The auxiliary power supply (third energy storage unit 17c) operates the inside of the power supply station (first power / hydrogen supply station 10a), making it possible to use the auxiliary power supply as a starting power source for supplying hydrogen to the fuel cell. In other words, it becomes possible to efficiently store electricity obtained from hydrogen.

[0251] (Effects of using a renewable energy-derived power generation device (first power generation device 11)) It will become possible to convert surplus electricity generated from renewable energy sources, such as solar power, into hydrogen and store it. Storing hydrogen allows for energy storage in a smaller volume than storing electricity, and it degrades less over long periods of storage.

[0252] (Effects of using water obtained from a fuel cell (second power generation device 12), etc., as the electrolyte) By utilizing the water generated in the second power generation device 12 and the hydrogen storage unit 21 as an electrolyte, hydrogen can be produced even when the supply of water from an external source is limited.

[0253] (Effects of supplying power to the second flow control device (such as the pump 210 in the circulation path 200) with an auxiliary power source (third energy storage unit 17c) separate from the fuel cell energy storage unit (second energy storage unit 17b)) The auxiliary power supply (third energy storage unit 17c) operates the inside of the power supply station (first power and hydrogen supply station 10a), and the auxiliary power supply can be used as a starting power source for supplying water to the solar water heater 20 and the like.

[0254] (Application example of the first power and hydrogen supply station 10a, fifth embodiment) The first power and hydrogen supply station 10a of the fourth embodiment can be applied to charging and power supply stations for electric mobile devices such as the first electric vehicle c1 (see fifth embodiment, Figure 16). The following description will focus on the differences from the fourth embodiment. The switching unit 22 of the first power and hydrogen supply station 10a in the fifth embodiment further includes a fourth switching unit 22d between the third conversion unit 13a3 and the first energy storage unit 17a. In the fifth embodiment, as shown in Figure 16, the solar water heater 20, the first output terminal section 24b1, and the like may be omitted.

[0255] Furthermore, the third energy storage unit 17c may be omitted. In this case, the first energy storage unit 17a or the second energy storage unit 17b functions as an auxiliary power source. In the fifth embodiment, the first energy storage unit 17a functions as an auxiliary power source and supplies power to electrical equipment constituting the first power and hydrogen supply station 10a, such as the control device 13.

[0256] Furthermore, the second power generation device 12 and the hydrogen storage unit 21 may also be omitted. If the hydrogen storage unit 21 is omitted, the first power and hydrogen supply station 10a will omit its functions for supplying hydrogen to the outside and inside, and will function as a power supply station.

[0257] (Storage capacity of the first energy storage unit 17a and the second energy storage unit 17b) In the fifth embodiment, the charging capacity of the energy storage device in the first energy storage unit 17a is smaller than the charging capacity of the energy storage device in the second energy storage unit 17b. For example, the first energy storage unit 17a is a lithium-ion battery with a voltage of 48V and an energy capacity of 10kWh, and the second energy storage unit 17b is a lithium-ion battery with a voltage of 48V and an energy capacity of 120kWh.

[0258] (1st load 19a~4th load 19d) In the fifth embodiment, the first energy storage unit 17a supplies power to the first load 19a to the fourth load 19d. In the fifth embodiment, the first load 19a to the fourth load 19d are electrical equipment of the first power and hydrogen supply station 10a. The first load 19a includes a lighting device that illuminates the area around the first power and hydrogen supply station 10a. The second load 19b includes an imaging device that acquires image information of the surrounding area. The third load 19c includes a locking control device for a luggage storage area 29 (such as a delivery box) and a temperature control device for cooling or heating the luggage storage area, both of which are installed at the first power and hydrogen supply station 10a. The fourth load 19d includes a display device (such as a station-side display unit 15) that outputs information regarding the charging status of the first energy storage unit 17a and the second energy storage unit 17b.

[0259] (Fourth switching section 22d) The fourth switching unit 22d switches the destination of the power supply from the input terminal unit 24a between the first energy storage unit 17a and the second energy storage unit 17b.

[0260] (Input terminal section 24a) The input terminal 24a of the fifth embodiment is connected to an external power source (for example, a commercial power source or the first electric vehicle c1) in a detachable manner. Power from an external power source connected to the input terminal 24a is supplied to the first energy storage unit 17a or the second energy storage unit 17b via the input terminal 24a and the third conversion unit 13a3.

[0261] (Switching control of the first switching unit 22a, the second switching unit 22b, and the fourth switching unit 22d) Normally, the control device 13 controls the first switching unit 22a and the second switching unit 22b so that power from the DC power generator 11a and the AC power generator 11b is supplied to the first energy storage unit 17a. If the charge rate R1a of the first energy storage unit 17a is higher than or equal to the full charge threshold Thrf, and the power P supplied from the first power generator 11 (DC power generator 11a, AC power generator 11b) is greater than or equal to the power threshold Thp, then the control device 13 determines that surplus power is being generated and controls the first switching unit 22a and the second switching unit 22b so that power from the DC power generator 11a and the AC power generator 11b is supplied to the second energy storage unit 17b.

[0262] Power from the commercial power source is mainly supplied to the first energy storage unit 17a. When a commercial power supply is connected to the input terminal 24a, the control device 13 controls the fourth switching unit 22d so that power from the commercial power supply is supplied to the first energy storage unit 17a. However, if the charge rate R1a of the first energy storage unit 17a is higher than or equal to the full charge threshold Thlf, the control device 13 determines that surplus power is being generated and controls the fourth switching unit 22d so that power from the commercial power supply is supplied to the second energy storage unit 17b.

[0263] The electricity from the electric vehicle is mainly supplied to the second energy storage unit 17b. When the power supply terminal of the first electric vehicle c1 is connected to the input terminal section 24a, the control device 13 controls the fourth switching section 22d so that power from the first electric vehicle c1 is supplied to the second energy storage section 17b. However, if the charge rate R1b of the second energy storage unit 17b is higher than or equal to the full charge threshold Thlf, the control device 13 assumes that surplus power is being generated and controls the fourth switching unit 22d so that power from the first electric vehicle c1 is supplied to the first energy storage unit 17a.

[0264] The control device 13 or the like automatically determines whether commercial power is connected to the input terminal 24a or whether the power supply terminal of the first electric vehicle c1 is connected. The control device 13 makes the decision based on information from the detection unit 13c provided around the input terminal 24a. The detection unit 13c detects the voltage value of the power supplied to the input terminal 24a, the current value, etc., or takes an image of the area around the equipment connected to the input terminal 24a.

[0265] Furthermore, separate input terminals 24a for connecting to a commercial power supply and input terminals 24a for connecting to the electric vehicle's power supply unit may be provided. In this case, separate third conversion units 13a3 for AC / DC conversion of power from the commercial power supply and third conversion units 13a3 for AC / DC conversion of power from the electric vehicle's power supply unit are provided. Also, the fourth switching unit 22d is omitted.

[0266] In the fifth embodiment, the first power and hydrogen supply station 10a was described as being fixed to the ground as a charging and power supply stand. However, the first power and hydrogen supply station 10a may also be provided with a mobile unit 50 (see Figure 17). The mobile unit 50 moves the housing 25 that holds the various parts of the first power and hydrogen supply station 10a through at least one of the following environments: on land, on water, underwater, or in the air. While the mobile unit 50 is moving, power may be supplied from the second power storage unit 17b to the electric mobile device c5 connected to the second output terminal unit 24b2. Examples of electric mobility devices c5 include electric vehicles, as well as ships and airplanes that can be powered by electricity. The mobile unit 50 is driven by power from the second energy storage unit 17b or the first energy storage unit 17a.

[0267] (Effects of supplying power from and charging the electric mobility device) Power can be supplied from the electric mobility device c5 (such as the first electric vehicle c1) via the input terminal 24a, and the electric mobility device c5 can be charged via the second output terminal 24b2, making it possible to use the first power and hydrogen supply station 10a as a charging and power supply station for the electric mobility device c5. The first energy storage unit 17a can be used to drive the internal loads of the first power and hydrogen supply station 10a, and the second energy storage unit 17b can be used to charge the electric mobile device c5 or to supply power from the electric mobile device c5.

[0268] (The effect of providing a luggage storage area on the charging / power supply stand) The luggage storage area 29 of the charging / power supply station (first power / hydrogen supply station 10a) can be used as a delivery box. Furthermore, by having the first power storage unit 17a drive the locking control device (third load 19c) of the luggage storage area 29, it becomes possible to operate the charging / power supply station and the delivery box without relying on an external power supply.

[0269] (The benefits of having mobile power and hydrogen supply stations) After the mobile unit 50 has moved to a predetermined location, or while the mobile unit 50 is moving, it becomes possible to supply power from the second power storage unit 17b to the electric mobile device c5 connected to the second output terminal unit 24b2.

[0270] (Example of application of power supply to hydrogen generator 21b) In the second to fifth embodiments, an example was described in which power to the hydrogen generator 21b is supplied from the first energy storage unit 17a. However, power may also be supplied directly to the hydrogen generator 21b from the first power generator 11 or an external power source connected to the input terminal unit 24a, without going through the first energy storage unit 17a. In this case, the hydrogen generator 21b performs electrolysis of the electrolyte based on power from the first power generator 11, the first energy storage unit 17a, and at least one of the external power source.

[0271] (An example of an application that omits the supply of hydrogen to an external source) In the first to fifth embodiments, the hydrogen obtained from the hydrogen generator 21b was described as being supplied to the outside via the hydrogen supply unit 21g. However, this hydrogen may also be used solely for supplying the second power generator 12. In this case, the hydrogen supply unit 21g is omitted, and the first power and hydrogen supply station 10a omits its function of supplying hydrogen to the outside and functions as a power supply station.

[0272] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These embodiments can be carried out in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims and their equivalents. [Explanation of Symbols]
