Description

[Technical Field]

[0001] The present invention relates to a mobile hydrogen supply system. [Background technology]

[0002] Hydrogen is used in a variety of fields, such as the semiconductor manufacturing industry, the petrochemical industry, and power generation.

[0003] A conventional technology for using hydrogen as an energy source is to operate a fixed hydrogen supply device using electricity generated from natural energy sources such as sunlight, and generate electricity using hydrogen supplied from the hydrogen supply device as fuel in a power generation device such as a fixed fuel cell (Patent Document 1).

[0004] Another conventional technology for using hydrogen as an energy source involves mounting a hydrogen supply device and a power generation device such as a fuel cell on a mobile object such as a forklift, and using the electricity generated by the power generation device to move the mobile object (Patent Document 2).

[0005] [Patent Document 1] Japanese Patent Publication No. 2020-47417 [Patent Document 2] Japanese Patent Application Publication No. 2019-7609 Summary of the Invention [Problem to be solved by the invention]

[0006] Conventionally, hydrogen supply systems that supply hydrogen have generally been installed in fixed locations. However, if there is a shortage of hydrogen in a hydrogen demand area due to a disaster or other cause, there is a problem that the shortage cannot be resolved in a short period of time. Therefore, if a mobile hydrogen supply system can be installed and moved to a hydrogen demand area and hydrogen can be supplied from the hydrogen supply system, it is thought that it will be possible to resolve short-term hydrogen shortages.

[0007] However, when a portable hydrogen supply system is transported to a hydrogen demand area and installed there, the following problems may arise.

[0008] A problem with mobile hydrogen supply systems is that even if the hydrogen supply system can be transported, it will be difficult to supply hydrogen to hydrogen demand areas unless available energy sources such as electricity required to supply hydrogen can be secured at the hydrogen demand areas to which the hydrogen supply system is transported.

[0009] An object of the present invention is to provide a mobile hydrogen supply system that can ensure a usable energy source in a hydrogen demand area where the system is transported and installed to supply hydrogen. [Means for solving the problem]

[0010] A mobile hydrogen supply system according to the present disclosure comprises a power generation device that generates electricity using natural energy and a hydrogen generation device that generates hydrogen, the hydrogen generation device being operable using the electricity generated by the power generation device, and the power generation device and the hydrogen generation device being transportable. [Effects of the Invention]

[0011] According to the mobile hydrogen supply system of the present disclosure, when the hydrogen generator supplies hydrogen, it is possible to ensure an energy source that can be used in the hydrogen demand area to which the hydrogen supply system is delivered.

[0013] The following describes embodiments of the present invention with reference to the drawings. While several embodiments will be described below, it is anticipated from the beginning that the configurations described in each embodiment may be combined as appropriate. In the following drawings, the same or corresponding parts are designated by the same reference numerals, and their description will not be repeated.

[0014] First Embodiment [Configuration of the mobile hydrogen supply system 100] Fig. 1 is a diagram showing a hydrogen generator 1 and a natural energy power generator 12 of a mobile hydrogen supply system 100 according to the first embodiment. Figs. 1(A-1), (A-2), and 1(B) show variations in the configuration of the hydrogen generator 1 and the natural energy power generator 12 included in the hydrogen supply system 100.

[0015] The hydrogen supply system 100 includes at least a hydrogen generator 1 and a natural energy power generation device 12 as shown in Fig. 1. The hydrogen generator 1 is installed inside a box-shaped mobile structure 10 and generates hydrogen. The hydrogen generator 1 and the natural energy power generation device 12 can be transported to any location by a transport vehicle such as transport vehicles 15, 15a, and other transport devices such as railway vehicles and airplanes may also be used during the transport process.

[0016] 1(A-1) and (A-2) show an example of a hydrogen supply system 100 in which a natural energy power generation device 12 and a hydrogen generation device 1 are mounted on a transport vehicle 15 in an attachable and detachable manner.

[0017] The hydrogen generation device 1 includes a mobile structure 10, a generation unit 11, a power storage unit 13, and a control unit 14. The natural energy power generation device 12 is a device that generates power using natural energy, which will be described later. The natural energy power generation device 12 is mounted on the outside or inside of the mobile structure 10.

[0018] The natural energy power generation device 12 supplies the electric power generated from natural energy to the power storage unit 13 via an electric cable 92. The power storage unit 13 includes a storage battery, and stores the electric power supplied from the natural energy power generation device 12.

[0019] The generator 11 is a device that operates using electricity stored in the power storage unit 13 and generates hydrogen by electrolyzing water. The water to be electrolyzed is stored in a tank included in the generator 11.

[0020] The control unit 14 operates using the power stored in the power storage unit 13, and is a device that controls each device in the hydrogen generation device 1, such as controlling the generation of hydrogen in the generation unit 11 and controlling the storage and discharge of electricity in the power storage unit 13. The control unit 14 is configured to include a CPU (Central Processing Unit), memory (including volatile memory and non-volatile memory), and an input / output buffer for inputting and outputting various signals. The CPU controls each device in the hydrogen generation device 1 by executing a program stored in the memory.

[0021] The hydrogen generated by the generation unit 11 of the hydrogen generator 1 is supplied to the outside of the hydrogen generator 1 via a pipe 8 connected to the generation unit 11 .

[0022] The hydrogen generator 1 may be provided with a storage unit for storing hydrogen generated by the generator 11, and the hydrogen stored in the storage unit may be supplied to the outside of the hydrogen generator 1 via a pipe 8. The storage unit is controlled by a controller 14 to adjust the temperature of the stored hydrogen. The storage unit may also have a function of changing the pressure of the stored hydrogen.

[0023] The electric power stored in the power storage unit 13 can be supplied to the outside of the hydrogen generation apparatus 1 via an electric cable 9 connected to the power storage unit 13. In addition, the power storage unit 13 can be supplied with electric power via the electric cable 9 from various power supply devices provided outside the hydrogen generation apparatus 1, and the supplied electric power can be stored.

[0024] In the hydrogen supply system 100 shown in FIGS. 1(A-1) and (A-2), a natural energy power generation device 12 and a hydrogen generation device 1 are mounted on a transport vehicle 15. The transport vehicle 15 can be self-propelled by driving a plurality of wheels 16 with a drive unit including an internal combustion engine such as a gasoline engine or a diesel engine. The transport vehicle 15 can be self-propelled by a driver who sits in a driver's cab 17 and operates the vehicle. The hydrogen generation device 1 may also be mounted in a fixed position on the transport vehicle 15.

[0025] With this configuration, in the hydrogen supply system 100 shown in Figures 1 (A-1) and (A-2), the hydrogen generation device 1 with the natural energy power generation device 12 mounted thereon, or the hydrogen generation device 1 and the natural energy power generation device 12 mounted separately, can be transported to a destination by a transport vehicle 15.

[0026] The natural energy power generation device 12 and the hydrogen generation device 1 may be mounted on a mobile structure 10 housing the hydrogen generation device 1 as shown in Figure 1 (A-1), or may be mounted separately on a single transport vehicle 15 as shown in Figure 1 (A-2).

[0027] The hydrogen supply system 100 shown in Figures 1 (A-1) and (A-2) can supply hydrogen and electricity outside the hydrogen generation device 1 when the hydrogen generation device 1 and the natural energy power generation device 12 are loaded onto a transport vehicle 15 at the destination, or when either the hydrogen generation device 1 or the natural energy power generation device 12 is unloaded from the transport vehicle 15.

[0028] 1(B) shows an example of a hydrogen supply system 100 in which the hydrogen generator 1 is mounted on a transport vehicle 15 so as to be attachable and detachable, and the natural energy power generation device 12 is mounted on a transport vehicle 15a different from the transport vehicle 15 so as to be attachable and detachable. The transport vehicle 15a has the same configuration as the transport vehicle 15.

[0029] With this configuration, in the hydrogen supply system 100 shown in FIG. 1(B), the two transport vehicles 15 and 15a can transport the hydrogen generator 1 and the natural energy power generator 12 to a destination.

[0030] The hydrogen supply system 100 shown in Figure 1(B) is capable of supplying hydrogen and electricity to the outside of the hydrogen generation device 1 by connecting the hydrogen generation device 1, which is mounted on or removed from the transport vehicle 15, and the natural energy power generation device 12, which is mounted on or removed from the transport vehicle 15a, via an electric cable 92 at the destination.

[0031] The hydrogen generation device 1 and natural energy power generation device 12 of the hydrogen supply system 100 shown in Figure 1(B) are similar to those shown in Figures 1(A-1) and (A-2) except that they are mounted on different transport vehicles 15, 15a, and supply hydrogen and electricity in the same manner.

[0032] In addition, the mobile structure 10 may be configured integrally with the transport vehicle 15, and the natural energy power generation device 12, which is separate from the mobile structure 10, may be configured integrally with the transport vehicle 15, 15a.

[0033] As shown in Figures 1(A-1), (A-2), and 1(B), the hydrogen supply system 100 can move the hydrogen generator 1 and the natural energy power generation device 12 using one or more transport vehicles. This allows the entire hydrogen supply system 100 to be easily moved.

[0034] [Configuration of natural energy power generation equipment] Next, the configuration of the natural energy power generation device 12 will be described.

[0035] FIG. 2 is a side view of the mobile structure 10 showing the configuration of the natural energy power generation device 12 according to the first embodiment shown in FIG. 1(A-1).

[0036] Referring to Fig. 2, doors 10A and 10B in a double door style are provided on the side of the mobile structure 10. Fig. 2 shows the state in which the doors 10A and 10B provided on the side of the mobile structure 10 are open.

[0037] The aforementioned generation unit 11, storage unit 13, and control unit 14 included in the hydrogen generation device 1, as well as a part of the natural energy power generation device 12, are configured to be able to be housed inside the mobile structure 10, and can be transported to any location by the aforementioned transport vehicle 15.

[0038] A solar power generation device 72 including a solar cell module 721 is provided in the center of the top surface of the mobile structure 10. The solar power generation device 72 generates electricity in response to sunlight received by the solar cell module 721. The electricity generated by the solar power generation device 72 is supplied to and stored in the power storage unit 13 shown in FIG. 1 via an electric cable 92.

[0039] A wind power generation device 73 including a windmill 731 and a generator 732 is provided on the outside of the side wall surface of the mobile structure 10. In the wind power generation device 73, the generator 732 generates electricity as the windmill 731 rotates in response to wind. The power generated by the wind power generation device 73 is supplied to and stored in the power storage unit 13 shown in FIG. 1 via an electric cable 92. The power generated by the wind power generation device 73 is supplied to and stored in the power storage unit 13 shown in FIG. 1. The wind power generation device 73 may be configured to change its vertical position using an elevator device (not shown) as necessary. For example, when generating electricity using the wind power generation device 73, the wind power generation device 73 is positioned in an elevated position as shown in FIG. 2 so that the windmill 731 can rotate in response to wind. On the other hand, when not generating electricity using the wind power generation device 73 or during transportation, the elevator device may be used to lower the windmill 731 to a position lower than the height of the mobile structure 10. When the wind power generation device 73 is transported by the transport vehicle 15 and arrives at its destination, it is attached to the outside of the side wall of the mobile structure 10 so that the position of the wind power generation device 73 is higher than the height of the mobile structure 10 as shown in Figure 2, and is in a state where it can generate electricity.

[0040] The wind power generation device 73 may also be storable inside the mobile structure 10. If the wind power generation device 73 is storable inside the mobile structure 10 in this way, it is possible to avoid the mobile structure 10 violating regulations regarding size restrictions on packaging size during transportation, such as when transporting by sea. Furthermore, since the wind power generation device 73 can be stored inside the mobile structure 10 during transportation, it is possible to avoid damage during transportation.

[0041] Furthermore, an opening / closing door (not shown) that opens and closes to allow the wind turbine 731 to appear and disappear between the inside and outside of the mobile structure 10 may be provided on the top surface of the mobile structure 10. The opening / closing door is opened when the wind turbine 731 is raised and lowered and when the wind turbine 731 is protruding above the mobile structure 10, and closed when the wind turbine 731 is stored inside the mobile structure 10. In such a configuration, the wind power generation device 73 can be stored inside the mobile structure 10, and is raised and lowered when necessary by a lifting device (not shown) provided inside the mobile structure 10.

[0042] Inside the mobile structure 10, a hydroelectric power generating device 74 is held on the inner wall surface of the door 10B. The hydroelectric power generating device 74 has a water wheel 741 mounted on the bottom of a base 743, and a generator 742 mounted inside the base 743. The generator 742 generates electricity based on the rotation of the water wheel 741. The hydroelectric power generating device 74 is mounted so as to be easily removable from the inner wall surface of the door 10B.

[0043] The hydroelectric power generation device 74 is removed from the interior wall surface of the door 10B, and a base 743 is installed above any waterway so that the waterwheel 741 can receive the water flow in the waterway. The hydroelectric power generation device 74 generates electricity as the waterwheel 741 rotates in response to the water flow within the waterway. The electricity generated by the hydroelectric power generation device 74 is supplied to the power storage unit 13 shown in FIG. 1 via an electric cable 92 and stored therein. The hydroelectric power generation device 74 may be mounted on a cart, such as a hand-operated cart or a self-propelled cart, and stored inside the mobile structure 10. In this case, the hydroelectric power generation device 74 is transported to the destination while stored inside the mobile structure 10, and upon arrival at the destination, it is loaded onto the cart and pulled out from the interior of the mobile structure 10 to be installed in a location where it can generate electricity. The hydroelectric power generation device 74 may be attached to at least one of the exterior and interior walls of the door 10A or door 10B.

[0044] The natural energy power generation system 12 can generate power using at least one of the natural energy sources of solar power, wind power, and hydropower using at least one of the solar power generation system 72, wind power generation system 73, and hydropower generation system 74. This allows the natural energy power generation system 12 to generate power according to the environment, such as the weather and topography at the target value. The natural energy power generation system 12 can also generate power by combining all or some of the solar power generation system 72, wind power generation system 73, and hydropower generation system 74 depending on the environment. This allows power to be generated to the extent possible even in environments where a power supply is unavailable.

[0045] The solar power generation device 72 can generate power even during transportation by keeping the solar cell module 721 exposed at the top of the mobile structure at all times during transportation. This allows power generation using natural energy more effectively, and ensures a stable amount of power stored in the power storage unit 13.

[0046] The natural energy power generation device 12 is provided with a control unit (not shown). The control unit is configured similarly to the control unit 14, and controls power generation devices such as the solar power generation device 72, the wind power generation device 73, and the hydroelectric power generation device 74 by executing a program stored in memory. The control unit may be configured with one control unit that comprehensively controls the power generation devices 72, 73, and 74, or may be configured with three control units that are individually provided for the power generation devices 72, 73, and 74. [Other configurations of the mobile hydrogen supply system 100] FIG. 3 is a diagram showing another configuration of the hydrogen supply system 100 according to the first embodiment.

[0047] The hydrogen supply system 100 shown in Fig. 3 includes the hydrogen generation device 1 and natural energy power generation device 12 described above, as well as a hydrogen storage device 2, a hydrogen transport device 3, a hydrogen power generation device 4, and natural energy power generation devices 22, 32, and 42. The hydrogen generation device 1 and the natural energy power generation device 12 may have any of the configurations shown in Fig. 1(A), Fig. 1(B), and Fig. 1(C). Fig. 3 shows the hydrogen generation device 1 and the natural energy power generation device 12 having the configuration shown in Fig. 1(A) as a representative example.

[0049] The hydrogen storage device 2 is a device that stores the hydrogen generated by the hydrogen generation device 1. The hydrogen transport device 3 is a device that seals the hydrogen stored in the hydrogen storage device 2 in a cartridge, which is a container, and houses and transports the cartridge. Such a cartridge is called a hydrogen cartridge. The hydrogen power generation device 4 is a device that generates power using the hydrogen stored in the hydrogen storage device 2 as fuel.

[0050] Similar to the hydrogen generation device 1, the hydrogen storage device 2, the hydrogen delivery device 3, and the hydrogen power generation device 4 are each mounted in a removable and attachable manner on the corresponding transport vehicles 25, 35, and 45. The transport vehicles 25, 35, and 45 each have a corresponding plurality of wheels 26, 36, and 46, and have a configuration similar to that of the transport vehicle 15. Note that similar to the hydrogen generation device 1, the hydrogen storage device 2, the hydrogen delivery device 3, and the hydrogen power generation device 4 may each be fixedly mounted on the corresponding transport vehicles 25, 35, and 45.

[0051] The hydrogen storage device 2 includes a mobile structure 20, a storage unit 21, a power storage unit 23, and a control unit 24. The natural energy power generation device 22 is configured similarly to the natural energy power generation device 12. The natural energy power generation device 22 is mounted on the outside or inside of the mobile structure 20. The power storage unit 23 includes a storage battery and stores the electricity generated by the natural energy power generation device 22.

[0052] The storage unit 21 can be connected to the generation unit 11 of the hydrogen generation device 1 via a pipe 8. When the pipe 8 is not used, such as when the hydrogen storage device 2 is being transported, the pipe 8 is stored in the hydrogen storage device 2 or another device. When the storage unit 21 is connected to the generation unit 11 via the pipe 8, hydrogen generated in the generation unit 11 is supplied via the pipe 8. The storage unit 21 operates using electricity stored in the power storage unit 23, and stores the hydrogen supplied from the generation unit 11. The storage unit 21 has a function to adjust the temperature of the stored hydrogen. The storage unit 21 may also have a function to change the pressure of the stored hydrogen.

[0053] Control unit 24 is a device that operates using the power stored in power storage unit 23 and controls hydrogen storage device 2, and is configured similarly to control unit 14. The CPU of control unit 24 controls each device in hydrogen storage device 2, such as controlling the storage temperature in storage unit 21 and controlling the storage and discharge of electricity in power storage unit 23.

[0054] The hydrogen transport device 3 includes a mobile structure 30, a storage unit 31, a power storage unit 33, and a control unit 34. The natural energy power generation device 32 is configured similarly to the natural energy power generation device 12, and is a device that generates power using natural energy. The natural energy power generation device 32 is mounted on the mobile structure 30. The power storage unit 33 includes a storage battery, and stores the power generated by the natural energy power generation device 32.

[0055] The accommodation unit 31 can be connected to the storage unit 21 of the hydrogen storage device 2 via a pipe 8. When the pipe 8 is not used, such as when the hydrogen transportation device 3 is being transported, the pipe 8 is stored in the hydrogen transportation device 3 or another device. When the accommodation unit 31 is connected to the storage unit 21, hydrogen stored in the storage unit 21 is supplied to the accommodation unit 31 via the pipe 8. The accommodation unit 31 operates using electricity stored in the electricity storage unit 33, and stores the hydrogen supplied from the storage unit 21 in a plurality of cartridges.

[0056] The control unit 34 is a device that operates using the power stored in the power storage unit 33 and controls the hydrogen transportation device 3, and is configured similarly to the control unit 14. The CPU of the control unit 34 controls each device in the hydrogen transportation device 3, such as control related to the storage of hydrogen, such as temperature control in the storage unit 31, control related to the sealing of hydrogen into the cartridges stored in the storage unit 31, and control related to the storage and discharge of electricity in the power storage unit 33.

[0057] The hydrogen power generation device 4 includes a mobile structure 40, a fuel cell unit 41, a power storage unit 43, and a control unit 44. The natural energy power generation device 42 is configured similarly to the natural energy power generation device 12. The natural energy power generation device 42 is mounted on the mobile structure 40. The power storage unit 43 includes a storage battery and stores the electricity generated by the natural energy power generation device 42.

[0058] The fuel cell unit 41 can be connected to the storage unit 21 of the hydrogen storage device 2 via piping 8. When the piping 8 is not in use, such as when the hydrogen power generation device 4 is being transported, the piping 8 is stored in the hydrogen power generation device 4 or another device. When the fuel cell unit 41 is connected to the storage unit 21 via piping 8, hydrogen stored in the storage unit 21 is supplied to the fuel cell unit 41 via piping 8. The fuel cell unit 41 operates using electricity stored in the electricity storage unit 43, and generates electricity using hydrogen supplied from the storage unit 21 as fuel. The electricity generated by the fuel cell unit 41 is supplied to the outside of the hydrogen power generation device 4.

[0059] The control unit 44 is a device that operates using the power stored in the power storage unit 43 and controls the hydrogen power generation system 4, and is configured similarly to the control unit 14. The CPU of the control unit 44 controls each device in the hydrogen power generation system 4, such as control related to power generation in the fuel cell unit 41 and control related to power storage and discharge in the power storage unit 43.

[0060] 3, in the hydrogen generation device 1, hydrogen storage device 2, hydrogen transportation device 3, and hydrogen power generation device 4, power storage units 13, 23, 33, and 43 are interconnected by electric cables 9, making it possible to transmit and receive stored electric power. Such control of power transmission and reception is performed by control units 14, 24, 34, and 44. This allows power to be supplied to power storage units with insufficient stored power, thereby mutually complementing the stored power amounts, thereby stabilizing the operation of the hydrogen supply system 100.

[0061] In the hydrogen supply system 100, the hydrogen generation device 1, the hydrogen storage device 2, the hydrogen transport device 3, and the hydrogen power generation device 4 are transported individually, so the system can be easily dispersed and moved.

[0062] Furthermore, since each of the natural energy power generation devices 12, 22, 32, and 42 can generate electricity using multiple power generation devices that use multiple types of natural energy, the amount of electricity supplied to the corresponding storage units 13, 23, 33, and 43 can be adjusted by changing the number of power generation devices used for power generation.

[0063] [Transportation of the mobile hydrogen supply system 100] In the hydrogen generation device 1, hydrogen storage device 2, hydrogen transportation device 3, and hydrogen power generation device 4, it is possible to generate electricity in the corresponding natural energy power generation devices 12, 22, 32, 42 using a solar power generation device such as solar power generation device 72 during transportation, and store the electricity in the corresponding storage units 13, 23, 33, 43.

[0064] In addition, while the hydrogen generation device 1, hydrogen storage device 2, hydrogen transportation device 3, and hydrogen power generation device 4 are being transported, it is possible to use a wind power generation device such as wind power generation device 73 to generate electricity using the corresponding natural energy power generation devices 12, 22, 32, and 42.

[0065] The hydrogen supply system 100 is a system that generates hydrogen and supplies it to the outside, and is configured by combining at least a hydrogen generation device 1 and a natural energy power generation device 12. The hydrogen supply system 100 may be configured by combining the hydrogen generation device 1 and the natural energy power generation device 12 with a hydrogen storage device 2. The hydrogen supply system 100 may also be a system that combines the hydrogen generation device 1, the natural energy power generation device 12, and the hydrogen storage device 2 with a hydrogen transport device 3 or a hydrogen power generation device 4.

[0066] The hydrogen supply system 100 may also be a system in which the hydrogen generator 1 and the natural energy power generator 12 are combined with one or both of the hydrogen transport device 3 and the hydrogen power generator 4. [Basic layout example of the mobile hydrogen supply system 100 after transportation] After the hydrogen supply system 100 is transported to the destination, the hydrogen generation device 1, the hydrogen storage device 2, the hydrogen transport device 3, and the hydrogen power generation device 4 are arranged in a grouped or distributed manner, and are connected using piping 8 and electric cables 9. This allows the hydrogen supply system 100 to be operated.

[0067] The basic arrangement of such a hydrogen supply system 100 is when the hydrogen demand area where hydrogen is supplied in cartridges from the hydrogen transport device 3, the electricity demand area where electricity is supplied from the hydrogen power generation device 4, and the hydrogen generation area where the hydrogen generation device 1 can stably generate hydrogen due to environmental factors such as natural energy are all the same. [Example of remote installation of the mobile hydrogen supply system 100 after transportation] Next, an example will be described in which at least some of the hydrogen generation device 1, the hydrogen storage device 2, the hydrogen transport device 3, and the hydrogen power generation device 4 that constitute the hydrogen supply system 100 are arranged separately.

[0068] In the hydrogen supply system 100, when the area where hydrogen is demanded by the hydrogen transport device 3, the area where electricity is demanded by the hydrogen power generation device 4, and the hydrogen generation area where the hydrogen generation device 1 can stably generate hydrogen are at least partially different due to environmental factors, at least some of the devices are located separately.

[0069] In this way, in the hydrogen supply system 100, by arranging at least some of the devices separately in multiple different locations, it is possible to stabilize the generation of hydrogen in the hydrogen generation device 1, and to stabilize the supply of hydrogen by the hydrogen transport device 3 and the supply of electricity by the hydrogen power generation device 4.

[0070] According to the hydrogen supply system 100, the transported hydrogen generator 1 can be operated using electric power generated from natural energy in the transported natural energy power generation device 12. As a result, when the hydrogen generator 1 supplies hydrogen, the hydrogen supply system 100 can secure an energy source that can be used in the hydrogen demand area to which the hydrogen supply system 100 is transported.

[0071] 3 and other figures, the hydrogen storage device 2, the hydrogen transport device 3, and the hydrogen power generation device 4 are also equipped with corresponding natural energy power generation devices 22, 32, and 42. As a result, when supplying hydrogen, the hydrogen supply system 100 can secure an energy source that can be used in areas where hydrogen is consumed, the hydrogen being transported by the hydrogen supply system 100.

[0072] Furthermore, since the hydrogen generation device 1, the hydrogen storage device 2, the hydrogen transportation device 3, and the hydrogen power generation device 4 are equipped with corresponding natural energy power generation devices 12, 22, 32, and 42, the hydrogen storage device 2, the hydrogen transportation device 3, and the hydrogen power generation device 4, as well as the natural energy power generation devices 12, 22, 32, and 42, can be easily transported.

[0073] 3, the hydrogen generation device 1 can be installed in a location where the natural energy power generation device 12 can easily generate electricity using natural energy, thereby ensuring an energy source regardless of the natural environment, such as weather, in the hydrogen demand area, or the social environment, such as the presence or absence of an energy source. Furthermore, since the hydrogen generation device 1 and the hydrogen storage device 2 can be installed in separate locations, it is easier to secure an installation location for the hydrogen supply system 100 than if these devices were integrated. This makes it possible to make the hydrogen supply system 100 less susceptible to environmental factors, such as the size of the installation location at the delivery destination.

[0074] Since each device in the hydrogen supply system 100 can be transported individually, the hydrogen supply system 100 can be transported along unpaved roads, making it easy to move the hydrogen supply system 100 to demand areas where paved roads are difficult to use, such as areas affected by natural disasters.

[0075] In the hydrogen supply system 100 shown in Figure 3, each device can be transported individually, so the hydrogen generation device 1 can be installed in a location where hydrogen can be easily generated, the hydrogen storage device 2 can be installed in a location where hydrogen can be easily stored, the hydrogen transportation device 3 can be installed in a location where hydrogen can be easily transported, and the hydrogen power generation device 4 can be installed in a location where it is easy to generate power.

[0076] In the hydrogen supply system 100 shown in FIG. 3, each device can be transported individually, so the hydrogen supply system 100 can be organized into a system in which devices are combined according to the demand at the demand location. [Hydrogen supply system 100 including power supply device] The hydrogen supply system 100 may further include a power supply device 5 enclosed by a two-dot chain line in FIG.

[0077] The power supply device 5 is provided inside the mobile structure 50. The mobile structure 50 is a mobile structure similar to the mobile structure 10. The power supply device 5 is a device that can supply power to the hydrogen generation device 1, the hydrogen storage device 2, the hydrogen transportation device 3, and the hydrogen power generation device 4 from an external source.

[0078] The power supply device 5 is mounted on a transport vehicle 55 so as to be attachable and detachable. The transport vehicle 55 has a plurality of wheels 56 and has a configuration similar to that of the transport vehicle 15. Note that, like the hydrogen generation device 1, the power supply device 5 may be fixedly mounted on the corresponding transport vehicle 55.

[0079] The power supply device 5 includes a mobile structure 50, a power storage unit 53, and a control unit 54. The natural energy power generation device 52 is configured similarly to the natural energy power generation device 12 shown in FIG. 2. The natural energy power generation device 52 is mounted on the mobile structure 50. The power storage unit 53 includes a storage battery and stores the power generated by the natural energy power generation device 52.

[0080] The power storage unit 53 includes a storage battery having a larger capacity than the storage batteries of the power storage units 13, 23, 33, and 43. The power storage unit 53 may include a storage battery having the same capacity as the storage batteries of the power storage units 13, 23, 33, and 43.

[0081] The control unit 54 is a device that operates using the power stored in the power storage unit 53 and controls the power supply device 5, and is configured similarly to the control unit 14 shown in Fig. 3. The CPU of the control unit 54 controls each device in the power supply device 5, such as control related to the storage and discharge of power in the power storage unit 53.

[0082] In the hydrogen supply system 100 including the power supply device 5, the power storage unit 53 of the power supply device 5 is connected to the power storage unit 13 of the hydrogen generation device 1, the power storage unit 23 of the hydrogen storage device 2, the power storage unit 33 of the hydrogen transportation device 3, and the power storage unit 43 of the hydrogen power generation device 4 by electric cables 91, and it is possible to transmit the electricity stored in the power storage unit 53. The control of such power transmission is performed by the control unit 54.

[0083] In the hydrogen supply system 100 including the power supply device 5, in addition to the effects obtained by the hydrogen supply system 100 not including the power supply device 5, the following effects can be obtained: By receiving a supply of power from the power storage device 53 of the power supply device 5, the power storage unit 13 of the hydrogen generation device 1, the power storage unit 23 of the hydrogen storage device 2, the power storage unit 33 of the hydrogen transportation device 3, and the power storage unit 43 of the hydrogen power generation device 4 can each replenish power to a power storage unit that has insufficient stored power, thereby stabilizing the operation of the hydrogen supply system 100.

[0084] Second Embodiment [Configuration of a mobile hydrogen supply system 101] In the second embodiment, an example is shown in which the hydrogen generation device 1 and the hydrogen storage device 2 are mounted on one transport vehicle 15c. The natural energy power generation device 12 is mounted on the outside or inside of the mobile structure 10 of the hydrogen generation device 1.

[0085] 4 is a diagram showing the configuration of a mobile hydrogen supply system 101 according to the second embodiment. The hydrogen supply system 101 differs from the hydrogen supply system 100 of the first embodiment in that the hydrogen generation device 1 and the hydrogen storage device 2 are mounted on a single transport vehicle 15c in an attachable and detachable manner.

[0086] As shown in FIG. 4, the hydrogen supply system 101 includes at least a hydrogen generator 1, a natural energy power generation device 12, and a hydrogen storage device 2.

[0087] The transport vehicle 15c has the same configuration as the transport vehicle 15. The hydrogen generation device 1 and the hydrogen storage device 2 may be fixedly mounted on the transport vehicle 15c.

[0088] The hydrogen supply system 101 includes at least a hydrogen generator 1, a natural energy power generation device 12, and a hydrogen storage device 2. The natural energy power generation device 12 is mounted on the outside or inside of the mobile structure 10 of the hydrogen generator 1.

[0089] With this configuration, in the hydrogen supply system 101 shown in FIG. 4, the hydrogen generation device 1 and the hydrogen storage device 2 can be transported to a destination by a single transport vehicle 15c.

[0090] The hydrogen supply system 101 shown in Figure 4 can connect, at the destination, the hydrogen generation device 1 mounted on or unloaded from the transport vehicle 15c to the hydrogen storage device 2 mounted on or unloaded from the transport vehicle 15c via piping 8 and electrical cable 9.

[0091] The hydrogen storage device 2 does not include a natural energy power generation device. Electric power stored in the power storage device 13 of the hydrogen generation device 1 is supplied to the power storage device 23 of the hydrogen storage device 2 via an electric cable 9. The hydrogen storage device 2 stores the electric power supplied from the power storage device 13 in the power storage device 23 and operates using the stored electric power.

[0092] In this way, when the hydrogen supply system 101 is configured to provide natural energy power generation devices for some of the devices, it is possible to reduce the number of natural energy power generation devices provided in the hydrogen supply system 101, thereby reducing the number of devices provided in the system. Furthermore, by providing natural energy power generation devices for some of the devices, the system configuration can be simplified.

[0093] The natural energy power generation device 12 may be provided separately from the hydrogen generation device 1 and may be transported by being loaded on a transport vehicle different from the transport vehicle 15c as shown in Fig. 1(B). The natural energy power generation device 12 may be transported by being loaded separately from the hydrogen generation device 1 and the hydrogen storage device 2 on a single transport vehicle 15c as shown in Fig. 1(A-2). [Other configurations of the hydrogen supply system 101] The hydrogen supply system 101 shown in Fig. 4 may include, in addition to the hydrogen generation device 1 and the hydrogen storage device 2, a transportable hydrogen delivery device 3 and a hydrogen power generation device 4, as in the configuration shown in Fig. 3. The hydrogen supply system 101 shown in Fig. 4 may further include a power supply device 5, which is surrounded by a two-dot chain line in Fig. 3.

[0094] In the hydrogen supply system 101, any two or three of the hydrogen transport device 3, the hydrogen power generation device 4, and the power supply device 5 may be mounted on one transport vehicle.

[0095] In the second embodiment, as shown in FIG. 4, multiple devices, namely, a hydrogen generation device 1 and a hydrogen storage device 2, which operate using electricity generated by a natural energy power generation device 12, can be transported together on a single transport vehicle 15c, thereby facilitating transportation of the hydrogen supply system 101.

[0096] Third Embodiment [Overall configuration of the mobile hydrogen supply system 102] 5 is a diagram showing the configuration of a hydrogen supply system 102 according to the third embodiment. In the third embodiment, a hydrogen supply system 102 that does not include a hydrogen storage device 2 will be described.

[0097] The hydrogen supply system 102 in FIG. 5 differs from the hydrogen supply systems 100 and 101 shown in FIGS. 1 to 4 in that it does not include the hydrogen storage device 2.

[0098] 5 includes a hydrogen generation device 1, a hydrogen delivery device 3, and a hydrogen power generation device 4. The hydrogen generation device 1, the hydrogen delivery device 3, and the hydrogen power generation device 4 are each equipped with a corresponding natural energy power generation device 12, 32, 42. [Connection example of the mobile hydrogen supply system 102 after transportation] When the hydrogen supply system 102 is deployed at the destination, it is connected, for example, as follows: The hydrogen generation device 1 and the hydrogen delivery device 3 are connected using piping 8 and an electric cable 9. The hydrogen generation device 1 and the hydrogen power generation device 4 are connected using piping 8 and an electric cable 9. The hydrogen delivery device 3 and the hydrogen power generation device 4 are connected using an electric cable 9.

[0099] The hydrogen transport device 3 has a storage unit 31 that can be connected to the generation unit 11 of the hydrogen generation device 1 via a pipe 8. When the storage unit 31 is connected to the generation unit 11 via the pipe 8, hydrogen generated in the generation unit 11 is supplied to the storage unit 31 via the pipe 8, and the hydrogen is sealed and stored in a plurality of cartridges.

[0100] In the hydrogen power generation device 4, the fuel cell unit 41 can be connected to the generation unit 11 of the hydrogen generation device 1 via piping 8. When the fuel cell unit 41 is connected to the generation unit 11 via piping 8, hydrogen generated in the generation unit 11 is supplied to the fuel cell unit 41 via piping 8, and the fuel cell unit 41 generates electricity using the hydrogen as fuel.

[0101] In the hydrogen supply system 102 of Figure 5, the hydrogen generation device 1, the hydrogen transportation device 3, and the hydrogen power generation device 4 have the power storage units 13, 33, and 43 interconnected by electric cables 9, making it possible to transmit and receive stored electricity.

[0102] In the third embodiment, the hydrogen supply system 102 does not include a hydrogen storage device, so the number of devices included in the system can be reduced, and the system configuration can be simplified. [Hydrogen supply system 102 including power supply device] The hydrogen supply system 102 may further include a power supply device 5 enclosed by a two-dot chain line in Fig. 5. The power supply device 5 has the same functions as those described in the first embodiment.

[0103] In a hydrogen supply system 102 including a power supply device 5, an electric cable 91 connects the power storage unit 53 of the power supply device 5 to the power storage units 13, 33, and 43 corresponding to the hydrogen generation device 1, hydrogen transportation device 3, and hydrogen power generation device 4, and electricity stored in the power storage unit 53 can be transmitted.

[0104] In the hydrogen supply system 102 including the power supply device 5, in addition to the effects obtained with the hydrogen supply system 102 not including the power supply device 5, it is possible to replenish power from the power supply device 5 to a storage unit that has insufficient stored power, thereby stabilizing the operation of the hydrogen supply system 102.

[0105] <Fourth embodiment> [Overall configuration of the mobile hydrogen supply system 103] 6 is a diagram showing the configuration of a hydrogen supply system 103 according to the fourth embodiment. The hydrogen supply system 103 differs from the hydrogen supply system 100 of the first embodiment in that, instead of the hydrogen storage device 2 and the hydrogen transport device 3, a hydrogen storage device 6 having the functions of storing and transporting hydrogen is provided.

[0106] The hydrogen storage device 6 is provided inside the mobile structure 60. The hydrogen storage device 6 stores the hydrogen generated by the hydrogen generation device 1, and transports the stored hydrogen sealed in a cartridge.

[0107] The hydrogen storage device 6 is mounted on a transport vehicle 65 so as to be attachable and detachable. The transport vehicle 65 has a plurality of wheels 66 and has a configuration similar to that of the transport vehicle 15. Note that the hydrogen storage device 6 may be fixedly mounted on the corresponding transport vehicle 65.

[0108] The hydrogen storage device 6 includes a mobile structure 60, a storage unit 61A, a housing unit 61B, a power storage unit 63, and a control unit 64. The natural energy power generation device 62 is configured similarly to the natural energy power generation device 12. The natural energy power generation device 62 is mounted on the mobile structure 60. The power storage unit 63 includes a storage battery and stores the electricity generated by the natural energy power generation device 62.

[0109] The storage unit 61A can be connected to the generation unit 11 of the hydrogen generation device 1 by a pipe 8. When the pipe 8 is not used, such as when the hydrogen storage device 6 is being transported, the pipe 8 is stored in the hydrogen storage device 6 or another device. When the storage unit 61A is connected to the generation unit 11 by the pipe 8, hydrogen generated in the generation unit 11 is supplied to the storage unit 61A via the pipe 8. The storage unit 61A operates using power stored in the power storage unit 63, and stores the hydrogen supplied from the generation unit 11.

[0110] The hydrogen stored in the storage unit 61A is supplied to the storage unit 61B via the pipe 8. The storage unit 61B operates using the electricity stored in the power storage unit 63, and stores the hydrogen supplied from the storage unit 61A in a plurality of hydrogen cartridges.

[0111] Control unit 64 is a device that operates using the power stored in power storage unit 63 and controls hydrogen storage device 6, and is configured similarly to control unit 14. The CPU of control unit 64 controls each device in hydrogen storage device 6, such as control related to hydrogen storage in storage unit 61A, such as storage temperature control, control related to hydrogen storage in storage unit 61B, such as temperature control, and control related to storage and discharge in power storage unit 63.

[0112] In the hydrogen supply system 103, similar to the hydrogen supply system 100, the hydrogen generation device 1, the hydrogen storage device 6, and the hydrogen power generation device 4 can supply power to the storage unit that has insufficient stored power, thereby mutually complementing the stored power, thereby stabilizing the operation of the hydrogen supply system 103.

[0113] [Basic layout example of the mobile hydrogen supply system 103 after transportation] After the hydrogen supply system 103 is transported to the destination, the hydrogen generation device 1, the hydrogen storage device 6, and the hydrogen power generation device 4 are arranged in a grouped or distributed manner, and are connected using piping 8 and electric cables 9. This allows the hydrogen supply system 103 to be operated.

[0114] [Example of transportation after placement of hydrogen storage device 6 in hydrogen supply system 103] In the hydrogen supply system 103, the hydrogen storage device 6 has the function of storing and transporting hydrogen. The hydrogen storage device 6 is placed near the hydrogen generation device 1, and stores the hydrogen supplied from the hydrogen generation device 1 in storage section 61A. When the installation location of the hydrogen generation device 1 is far from the hydrogen demand area, the hydrogen storage device 6 is disconnected from the hydrogen generation device 1 as necessary and transported to the hydrogen demand area by transport vehicle 65, and supplies the hydrogen cartridges stored in storage section 61B to the hydrogen demand area.

[0115] In the hydrogen supply system 103 of the fourth embodiment, in addition to the effects obtained by the hydrogen supply system 100 of the first embodiment, the following effects are obtained: The hydrogen storage device 6 has the function of storing hydrogen and the function of sealing, storing, and transporting hydrogen in hydrogen cartridges, so the number of devices constituting the hydrogen supply system 103 can be reduced compared to the hydrogen supply system 100. [Hydrogen supply system 103 including power supply device] The hydrogen supply system 103 may further include a power supply device 5 enclosed by a two-dot chain line in Fig. 6. The power supply device 5 has the same functions as those described in the first embodiment.

[0116] In a hydrogen supply system 103 including a power supply device 5, the power storage unit 53 of the power supply device 5 is connected to the power storage unit 13 of the hydrogen generation device 1, the power storage unit 63 of the hydrogen storage device 6, and the power storage unit 43 of the hydrogen power generation device 4 by electric cables 91, and the electricity stored in the power storage unit 53 can be transmitted.

[0117] In the hydrogen supply system 103 including the power supply device 5, in addition to the effects obtained with the hydrogen supply system 103 not including the power supply device 5, it is possible to replenish power from the power supply device 5 to a storage unit that has insufficient stored power, thereby stabilizing the operation of the hydrogen supply system 103.

[0118] Fifth Embodiment [Overall configuration of the mobile hydrogen supply system 104] In the fifth embodiment, an example will be described in which natural energy power generation devices are provided in correspondence with some of the devices included in a hydrogen supply system. In the fifth embodiment, as a representative example, a hydrogen supply system 104 will be described in which natural energy power generation devices are provided in correspondence with some of the devices in the hydrogen supply system 100 of the first embodiment shown in Figure 3.

[0119] Fig. 7 is a diagram showing the configuration of a hydrogen supply system 104 according to the fifth embodiment. The hydrogen supply system 104 of the fifth embodiment differs from the hydrogen supply system 100 shown in Fig. 3 in that natural energy power generation devices are provided in correspondence with some of the hydrogen generation device 1, hydrogen storage device 2, hydrogen transport device 3, hydrogen power generation device 4, and power supply device 5.

As a result, power is stored in the power storage unit 23 of the hydrogen storage device 2 and the power storage unit 33 of the hydrogen transport device 3.

[0122] In the hydrogen supply system 104, when a natural energy power generation device is provided in correspondence with some of the devices, it is sufficient to provide a natural energy power generation device in correspondence with at least one of the devices, such as providing the natural energy power generation device 12 only in the hydrogen generation device 1.

Furthermore, by providing natural energy power generation devices to some of the devices, the system configuration can be simplified.

[0125] The configuration in which a natural energy power generation device is provided as part of the multiple types of devices included in the hydrogen supply system as shown in FIG. 7 may be applied to all of the hydrogen supply systems 100, 101, 102, and 103 described above.

[0126] The hydrogen supply systems 100, 101, 102, 103, and 104 shown in the first to fifth embodiments are configured to allow the hydrogen generation device 1 and the natural energy power generation device to be transported, and may further include at least one transportable device selected from the hydrogen storage devices 2 and 6, the hydrogen transport device 3, the hydrogen power generation device 4, and the power supply device 5.

For example, the natural energy power generation devices 12, 22, 32, 42, 52, and 62 described above may be configured as movable devices that allow the solar power generation device 72 to be extended and retracted. This configuration also includes a configuration in which the solar panel is simply removed during transportation.
