[Figure 3] 1 is a block diagram showing a configuration of a hydrogen fuel utilization system according to at least one embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings, etc. However, the present invention is not limited to the following embodiments as long as they do not contradict the spirit of the present invention.
[0010] (Hydrogen generation system) 1 is a block diagram showing the configuration of a hydrogen generation system according to at least one embodiment of the present invention. As shown in the figure, the hydrogen generation system 1 includes a raw water supply unit 10, a pure water generation unit 11 (11a, 11b, 11c, 11d), a hydrogen generation unit 12 (12a, 12b, . . . , 12j), and a hydrogen storage unit 13.
[0011] First, raw water is supplied from raw water supply unit 10 to pure water production unit 11. Then, pure water is produced from the supplied raw water in pure water production unit 11. The produced pure water is supplied from pure water production unit 11 to hydrogen production unit 12. Then, hydrogen is produced from the supplied pure water in hydrogen production unit 12. The produced hydrogen is supplied from hydrogen production unit 12 to hydrogen storage unit 13 and stored in hydrogen storage unit 13.
[0012] The raw water supply unit 10 and the pure water production unit 11, the pure water production unit 11 and the hydrogen production unit 12, and the hydrogen production unit 12 and the hydrogen storage unit 13 may be connected by pipes or the like, as shown by the arrows in Fig. 1. The raw water, pure water, and hydrogen may be supplied via these pipes or the like.
[0013] The raw water supply unit 10 supplies raw water to the pure water production unit 11. The raw water is used to produce pure water. The raw water may be industrial water, tap water, rainwater, well water, seawater, lake water, river water, or the like.
[0014] The raw water may be stored in a container such as a tank. The raw water supply unit 10 may then supply the raw water stored in the tank to the pure water production unit 11. Alternatively, the raw water supply unit 10 may supply raw water directly from a river or the like to the pure water production unit 11 without passing through a container such as a tank.
[0015] The raw water supply unit 10 is not particularly limited as long as it can supply raw water to the pure water production unit 11. The raw water supply unit 10 can be designed appropriately depending on the surrounding environment of the facility where the hydrogen generation system 1 is installed.
[0016] The pure water producing section 11 produces pure water from raw water.
[0017] 1, the hydrogen generation system 1 includes four pure water generators 11, ie, pure water generators 11a to 11d. The number of pure water generators 11 included in the hydrogen generation system 1 is not particularly limited, and can be appropriately designed depending on the size of the facility where the hydrogen generation system 1 is installed. For example, the number may be one, two, or five.
[0018] By having two or more pure water generating units 11 in the hydrogen generation system 1, even if some of the pure water generating units 11 in the hydrogen generation system 1 become unusable due to a malfunction or require replacement due to long-term use, the hydrogen generation system 1 can continue to operate by using the other pure water generating units 11.
[0019] The method by which the pure water generator 11 generates pure water from raw water is not particularly limited, and any known method can be used. For example, pure water may be generated by distillation, ion exchange resin, reverse osmosis membrane, electrical demineralization device (EDI device), etc.
[0020] The pure water generator 11 is not particularly limited as long as it can generate pure water from raw water. The pure water generator 11 can be designed appropriately depending on the type of raw water, the purity of the pure water suitable for generating hydrogen by the hydrogen generator 12, the desired amount of pure water to be generated, etc.
[0021] The hydrogen generating unit 12 generates hydrogen from the pure water generated by the pure water generating unit 11. The hydrogen generating unit 12 generates gaseous hydrogen by electrolyzing the pure water.
[0022] 1, the hydrogen generation system 1 includes ten hydrogen generation units 12, ie, hydrogen generation units 12a to 12j. The number of hydrogen generation units 12 included in the hydrogen generation system 1 is not particularly limited, and can be appropriately designed depending on the size of the facility in which the hydrogen generation system 1 is installed. For example, the number may be one, five, or 20.
[0023] By providing the hydrogen generation system 1 with two or more hydrogen generation units 12, even if some of the hydrogen generation units 12 provided in the hydrogen generation system 1 become unusable due to a malfunction or require replacement due to long-term use, the hydrogen generation system 1 can continue to operate by using the other hydrogen generation units 12.
[0024] The amount of gaseous hydrogen produced by the hydrogen producing unit 12 is 40 m 3 / h or more is preferable, and 50m 3 / h or more is more preferable, and 60m 3 / h or more is more preferable.
[0025] The hydrogen generator 12 is not particularly limited as long as it can generate hydrogen from pure water. The hydrogen generator 12 can be designed appropriately depending on the purity of the supplied pure water, the desired amount of hydrogen to be generated, and the like.
[0026] The hydrogen storage unit 13 stores the hydrogen generated by the hydrogen generation unit 12. The hydrogen storage unit 13 may include a mechanism for adjusting the pressure of the stored hydrogen.
[0027] 1, the hydrogen generation system 1 includes one hydrogen storage unit 13. The number of hydrogen storage units 13 included in the hydrogen generation system 1 is not particularly limited, and can be appropriately designed depending on the size of the facility where the hydrogen generation system 1 is installed. For example, the number may be one, two, or three.
[0028] There are no particular limitations on the hydrogen storage unit 13, and it may be any unit capable of storing hydrogen. For example, the hydrogen storage unit 13 may be a hydrogen storage alloy tank, a high-pressure gas tank, a gas tank, or the like.
[0029] A hydrogen storage alloy tank is a tank for storing hydrogen that is filled with an alloy that retains hydrogen as a hydride upon contact with hydrogen molecules. Compared to high-pressure gas tanks, hydrogen storage alloy tanks are able to store hydrogen at lower internal pressures, making them safer.
[0030] Although not shown, the hydrogen generation system 1 also includes a control unit that comprehensively controls the raw water supply unit 10, the pure water generation unit 11, the hydrogen generation unit 12, and the hydrogen storage unit 13. The control unit can also control the hydrogen generation system 1 so that it operates in conjunction with other systems.
[0031] In this way, the hydrogen generation system 1 can generate hydrogen from raw water by generating pure water from raw water, generating hydrogen from the generated pure water, and storing the generated hydrogen. Generating hydrogen from raw water reduces costs compared to purchasing commercially produced and sold hydrogen. In addition, it is possible to configure a hydrogen generation system that is suited to the surrounding environment and size of the facility where the hydrogen generation system 1 is installed.
[0032] Furthermore, since the hydrogen generator 12 generates hydrogen by electrolysis of pure water, gaseous oxygen is also generated when generating hydrogen. The oxygen generated by the hydrogen generator 12 can be stored in the same manner as hydrogen.
[0033] Fig. 2 is a block diagram showing the configuration of a hydrogen generation system corresponding to at least one embodiment of the present invention. The hydrogen generation system 1 shown in Fig. 2 is composed of a raw water supply unit 10, a pure water generation unit 11 (11a, 11b, 11c, 11d), a hydrogen generation unit 12 (12a, 12b, ..., 12j), a hydrogen storage unit 13, and an oxygen storage unit 14.
[0034] Regarding the manner in which hydrogen is generated from raw water and the generated hydrogen is stored, the above description can be adopted to the extent necessary. In the hydrogen generation system 1 shown in Figure 2, oxygen generated in the hydrogen generation unit 12 is supplied from the hydrogen generation unit 12 to the oxygen storage unit 14 and stored in the oxygen storage unit 14.
[0035] The raw water supply unit 10 and the pure water production unit 11, the pure water production unit 11 and the hydrogen production unit 12, the hydrogen production unit 12 and the hydrogen storage unit 13, and the hydrogen production unit 12 and the oxygen storage unit 14 may be connected by pipes or the like, as shown by the arrows in Fig. 2. The raw water, pure water, hydrogen, and oxygen may be supplied via these pipes or the like.
[0036] With regard to the raw water supply unit 10, the pure water production unit 11, the hydrogen production unit 12, and the hydrogen storage unit 13, the above descriptions can be adopted to the extent necessary.
[0037] The oxygen storage unit 14 stores the oxygen generated by the hydrogen generation unit 12.
[0038] 2, the hydrogen generation system 1 includes one oxygen storage unit 14. The number of oxygen storage units 14 included in the hydrogen generation system 1 is not particularly limited, and can be appropriately designed depending on the size of the facility where the hydrogen generation system 1 is installed. For example, the number may be one, two, or three.
[0039] The oxygen storage unit 14 is not particularly limited as long as it can store oxygen. For example, the oxygen storage unit 14 may be a high-pressure gas tank, a gas tank, etc. The oxygen storage unit 14 may be equipped with a mechanism for adjusting the pressure of the stored oxygen.
[0040] 2, the hydrogen generation system 1 is also equipped with a control unit that comprehensively controls the raw water supply unit 10, the pure water generation unit 11, the hydrogen generation unit 12, the hydrogen storage unit 13, and the oxygen storage unit 14. The control unit can also control the hydrogen generation system 1 so that it operates in conjunction with other systems.
[0041] By providing the hydrogen generation system 1 with the hydrogen storage unit 13 and the oxygen storage unit 14, it becomes easier to utilize hydrogen and oxygen in a hydrogen fuel utilization system, which will be described later.
[0042] (Hydrogen fuel system) 3 is a block diagram showing the configuration of a hydrogen fuel utilization system corresponding to at least one embodiment of the present invention. As shown in the figure, the hydrogen fuel utilization system 2 is composed of a solar panel 20, a power conditioner 21, commercial power 22, a switching device 23, a UPS with power storage function 24, a water buffer tank 25, a hydrogen generation system 26, a hydrogen pressurization device 27, a hydrogen buffer tank 28, an oxygen pressurization device 29, an oxygen buffer tank 30, and a hydrogen burner system 31. Here, the hydrogen generation system 26 refers to the hydrogen generation system 1 equipped with the hydrogen storage unit 13 and the oxygen storage unit 14 shown in FIG. 2.
[0043] The water buffer tank 25 and the hydrogen generation system 26, the hydrogen generation system 26 and the hydrogen pressurizer 27, the hydrogen pressurizer 27 and the hydrogen buffer tank 28, the hydrogen buffer tank 28 and the hydrogen burner system 31, the hydrogen generation system 26 and the oxygen pressurizer 29, the oxygen pressurizer 29 and the oxygen buffer tank 30, and the oxygen buffer tank 30 and the hydrogen burner system 31 may be connected by pipes or the like, as shown by the arrows in Fig. 3. The raw water, hydrogen, and oxygen may be supplied via these pipes or the like.
[0044] The solar panel 20 and the power conditioner 21, the power conditioner 21 and the switching device 23, the commercial power 22 and the switching device 23, the switching device 23 and the UPS 24 with power storage function, and the UPS 24 with power storage function and the pure water production unit 11, the hydrogen production unit 12, the hydrogen storage unit 13, and / or the oxygen storage unit 14 in the hydrogen production system 26 may each be electrically connected by a conductor or the like. Furthermore, the UPS 24 with power storage function and the water buffer tank 25, the hydrogen pressurizer 27, the hydrogen buffer tank 28, the oxygen pressurizer 29, the oxygen buffer tank 30, and / or the hydrogen burner system 31 may each be electrically connected by a conductor or the like. Electric power may be supplied via the conductor or the like.
[0045] The hydrogen fuel utilization system 2 generates electricity by converting sunlight into electricity using a solar panel 20. Hereinafter, the electricity generated by the solar panel 20 will be referred to as solar power generation. The electricity generated by solar power generation is converted by a power conditioner 21 into a state suitable for the environment in which the electricity will be used. For example, electricity generated by solar power generation is often direct current, so it is converted into alternating current so that it can be used in a general environment. There are no particular limitations on the power conditioner 21, as long as it can convert the electricity into a state suitable for the environment in which it will be used.
[0046] The hydrogen fuel utilization system 2 also includes commercial power 22. A switching device 23 switches between the supply of solar-generated power and the supply of commercial power 22. The switching device 23 preferentially supplies solar-generated power to the UPS 24 with power storage function, and when there is a shortage of solar-generated power, supplies commercial power 22 to the UPS 24 with power storage function. In this case, the switching device 23 may switch from the supply of solar-generated power to the supply of commercial power 22 when the amount of solar-generated power supply falls below a predetermined value. The switching device 23 may also switch from the supply of commercial power 22 to the supply of solar-generated power when the amount of solar-generated power supply exceeds a predetermined value.
[0047] By preferentially supplying solar-generated power to the UPS 24 with power storage function, it is possible to reduce the cost of supplying power compared to when prioritizing the supply of power from the commercial power 22. Furthermore, it is possible to operate the hydrogen fuel utilization system 2 even when the supply of power from the commercial power 22 is interrupted due to a disaster or other reason.
[0048] The UPS 24 with power storage function has the functions of receiving power supplied by solar power generation or commercial power 22, storing the supplied power, and supplying the supplied or stored power to external devices, etc. If the supplied power is interrupted, the UPS 24 with power storage function supplies the stored power to the external devices, etc., thereby preventing voltage drops or power outages in the external devices, etc. The hydrogen fuel utilization system 2 supplies power to the pure water generation unit 11, the hydrogen generation unit 12, the hydrogen storage unit 13, the oxygen storage unit 14, and / or the hydrogen burner system 31 using the UPS 24 with power storage function.
[0049] 3, power is supplied to the pure water generator 11, the hydrogen generator 12, the hydrogen storage unit 13, the oxygen storage unit 14, and / or the hydrogen burner system 31 by solar power generation, but the hydrogen fuel utilization system 2 need only be able to supply power to the pure water generator 11, the hydrogen generator 12, the hydrogen storage unit 13, the oxygen storage unit 14, and / or the hydrogen burner system 31 by renewable energy. There are no particular limitations on the renewable energy, and it may be energy that is naturally regenerated at a rate greater than the rate at which it is utilized. Examples of renewable energy include solar power generation, wind power generation, hydroelectric power generation, geothermal power generation, and microbial power generation.
[0050] In addition, the hydrogen fuel utilization system 2 can also supply electricity generated by a fuel cell system, which may be different from or the same as the fuel cell system described below, to the pure water generation unit 11, the hydrogen generation unit 12, the hydrogen storage unit 13, the oxygen storage unit 14, and / or the hydrogen burner system 31.
[0051] The amount of electricity supplied from renewable energy is not particularly limited, as long as it is enough to supply the electricity necessary to operate the pure water production unit 11, the hydrogen production unit 12, the hydrogen storage unit 13, the oxygen storage unit 14, and / or the hydrogen burner system 31. For example, 500 Wh of electricity may be supplied from renewable energy to operate the pure water production unit 11, and 5.5 to 6.5 kWh of electricity may be supplied to operate the hydrogen production unit 12.
[0052] The water buffer tank 25 stores raw water to be supplied to the pure water production unit 11 in the hydrogen generation system 26. For the water buffer tank 25, the description of the raw water supply unit 10 can be adopted to the extent necessary.
[0053] In the hydrogen generation system 26, pure water is produced from raw water supplied from the water buffer tank 25, and hydrogen and oxygen are produced from the pure water. The hydrogen and oxygen are then stored in the hydrogen generation system 26. With regard to the hydrogen generation system 26, the description of the hydrogen generation system 1 having the hydrogen storage unit 13 and the oxygen storage unit 14 shown in FIG. 2 can be adopted to the extent necessary.
[0054] The hydrogen stored in the hydrogen generation system 26 is supplied to a hydrogen pressurization device 27. There are no particular limitations on the hydrogen pressurization device 27, as long as it can pressurize hydrogen. The hydrogen pressurization device 27 can pressurize the hydrogen sealed inside the device by compressing it using a piston or the like. The pressurized hydrogen is supplied to a hydrogen buffer tank 28 while maintaining its high pressure state.
[0055] The hydrogen buffer tank 28 stores the high-pressure hydrogen supplied from the hydrogen pressurization device 27. There are no particular limitations on the hydrogen buffer tank 28, as long as it is capable of storing pressurized hydrogen. It is preferable that the hydrogen buffer tank 28 has high pressure resistance and high airtightness. The hydrogen stored in the hydrogen buffer tank 28 is supplied to the hydrogen burner system 31 as needed.
[0056] The supply of hydrogen from the hydrogen buffer tank 28 to the hydrogen burner system 31 may be continuous or intermittent.
[0057] The amount of hydrogen supplied from the hydrogen buffer tank 28 to the hydrogen burner system 31 may also be controlled by a control unit, which will be described later. In this case, the amount of hydrogen supplied to the hydrogen burner system 31 can be changed depending on the amount of hydrogen consumed and the remaining amount of hydrogen in the hydrogen burner system 31. In this case, the amount of hydrogen consumed and the remaining amount of hydrogen in the hydrogen burner system 31 are estimated, and the measured information is sent to the control unit. The control unit calculates the amount of hydrogen to be supplied from the hydrogen buffer tank 28 based on the amount of hydrogen consumed and the remaining amount of hydrogen in the hydrogen burner system 31.
[0058] The oxygen stored in the hydrogen generation system 26 is supplied to an oxygen pressurization device 29. There are no particular limitations on the oxygen pressurization device 29, as long as it can pressurize oxygen. The oxygen pressurization device 29 can pressurize the oxygen sealed inside the device by compressing it using a piston or the like. The pressurized oxygen is supplied to an oxygen buffer tank 30 while maintaining the high pressure state.
[0059] The oxygen buffer tank 30 stores the high-pressure oxygen supplied from the oxygen pressurizer 29. The oxygen buffer tank 30 is not particularly limited as long as it can store high-pressure oxygen. The oxygen buffer tank 30 preferably has high pressure resistance and high airtightness. The oxygen stored in the oxygen buffer tank 30 is supplied to the hydrogen burner system 31 as needed.
[0060] The supply of oxygen from the oxygen buffer tank 30 to the hydrogen burner system 31 may be continuous or intermittent.
[0061] The amount of oxygen supplied from the oxygen buffer tank 30 to the hydrogen burner system 31 may also be controlled by a control unit, which will be described later. In this case, the amount of oxygen supplied to the hydrogen burner system 31 can be changed depending on the amount of oxygen consumed and the remaining amount of oxygen in the hydrogen burner system 31. In this case, the amount of oxygen consumed and the remaining amount of oxygen in the hydrogen burner system 31 are estimated, and the measured information is sent to the control unit. The control unit calculates the amount of oxygen to be supplied from the oxygen buffer tank 30 based on the amount of oxygen consumed and the remaining amount of oxygen in the hydrogen burner system 31.
[0062] In Figure 3, the hydrogen fuel utilization system 2 is equipped with one each of a hydrogen pressurizer 27, a hydrogen buffer tank 28, an oxygen pressurizer 29, and an oxygen buffer tank 30. There is no particular limit to the number of hydrogen pressurizers 27, hydrogen buffer tanks 28, oxygen pressurizers 29, and oxygen buffer tanks 30 that the hydrogen fuel utilization system 2 is equipped with, and these can be designed appropriately depending on factors such as the size of the facility in which the hydrogen fuel utilization system 2 is installed. For example, there may be one, two, or three of them. Furthermore, the hydrogen fuel utilization system 2 may not be equipped with some or all of the hydrogen pressurizers 27, hydrogen buffer tanks 28, oxygen pressurizers 29, and oxygen buffer tanks 30.
[0063] The hydrogen supplied from the hydrogen buffer tank 28 to the hydrogen burner system 31 is used as fuel in the hydrogen burner system 31. Specifically, for example, the hydrogen supplied from the hydrogen buffer tank 28 can be mixed with oxygen supplied from the oxygen buffer tank 30 and burned. The hydrogen burner system 31 includes an incinerator, a boiler, a stove, a gas welding blowpipe, a gas burner, etc.
[0064] Alternatively, the hydrogen fuel utilization system 2 may use hydrogen supplied from the hydrogen buffer tank 28 as fuel for the fuel cell system. Specifically, for example, hydrogen supplied from the hydrogen buffer tank 28 may be reacted with oxygen supplied from the oxygen buffer tank 30 to generate electricity.
[0065] 3, the hydrogen fuel utilization system 2 also includes a control unit that comprehensively controls the solar panel 20, power conditioner 21, commercial power 22, switching device 23, UPS with power storage function 24, water buffer tank 25, hydrogen generation system 26, hydrogen pressurization device 27, hydrogen buffer tank 28, oxygen pressurization device 29, oxygen buffer tank 30, and hydrogen burner system 31. The control unit can also control the hydrogen fuel utilization system 2 so that it operates in conjunction with other systems. The control unit of the hydrogen fuel utilization system 2 may also serve as the control unit of the hydrogen generation system 26.
[0066] The control unit of the hydrogen generation system 26 and / or the hydrogen fuel utilization system 2 may be supplied with electricity from renewable energy.
[0067] In the above, the hydrogen generation system 26 refers to the hydrogen generation system 1 equipped with the hydrogen storage unit 13 and the oxygen storage unit 14 shown in Fig. 2, but it may also refer to the hydrogen generation system 1 equipped with the hydrogen storage unit 13 shown in Fig. 1. In that case, the hydrogen fuel utilization system 2 may not include the oxygen pressurization device 29 and the oxygen buffer tank 30.
[0068] In this way, the hydrogen fuel utilization system 2 produces pure water from raw water, produces hydrogen from the produced pure water, stores the produced hydrogen, uses the stored hydrogen as fuel, and supplies electricity from renewable energy, thereby producing hydrogen from raw water using renewable energy and using the produced hydrogen as fuel. In other words, if there is renewable energy and raw water, it is possible to use hydrogen as fuel.
[0069] Furthermore, if there is a surplus of hydrogen and / or oxygen produced in the hydrogen fuel utilization system 2, the surplus hydrogen and / or oxygen can be stored in a container such as a gas cylinder. The hydrogen and / or oxygen stored in a container such as a gas cylinder can then be supplied to another system. Alternatively, the hydrogen and / or oxygen stored in a container such as a gas cylinder can also be sold. [Explanation of symbols]
