れがあると言う問題がある。Conventionally used economic methods for transporting hydrogen include transporting it in high-pressure gas cylinders and using pipelines. The problem with the pipeline method is that it can only be used for transportation within a very limited range due to the cost of installing the pipeline. Another problem with the method of using high-pressure gas cylinders is that if a transport vehicle collides and the cylinder receives an impact, the cylinder tends to explode, causing a major disaster.

経済性を高めることもできる。That is, in the hydrogen transport method of the present invention, hydrogen is stored in a hydrogen storage alloy in a hydrogen storage alloy storage container (hereinafter referred to as alloy storage container) and transported by means of transportation such as a truck. The range is not limited, and the pressure applied to the alloy storage container is the equilibrium hydrogen pressure of the hydrogen storage alloy, so there is less risk of an explosion like in a high-pressure gas cylinder. Then, by increasing the number of hydrogen storage devices on the hydrogen delivery station side and hydrogen release devices on the hydrogen receiving station side to increase the transportation cycle of the alloy storage container, the amount of hydrogen transported can be increased accordingly. The heat transfer fluid used in the hydrogen storage device can be used as a heat transfer fluid to utilize the heat removed from the alloy storage container, or the hydrogen release device can use other cooling waste water as the heat transfer fluid to heat the alloy storage container. By doing so, it is possible to improve the overall economic efficiency of transportation.

1 is attached to the reaction accelerating tank 6, and the connecting joint 7 is connected to the connecting joint 7 in the reaction accelerating tank 6, and the valve 8 is opened to close the opening/closing door 6.
1 is closed, then valve 5 is opened, and hydrogen gas from storage tank 3 is transferred by compressor 4 to valve 5. Connection joint 7. It is supplied into the alloy storage container 12 through the valve 8 and the check valve 10. At that time, the pump 13 sends a cooling heat medium liquid into the reaction accelerating tank 6 from the inlet 62 and
3, the reaction heat is removed from the alloy storage container 12 and the hydrogen storage of the hydrogen storage alloy is promoted. When the hydrogen storage of the hydrogen storage alloy reaches saturation and the compressor 4 hardly works, the valve 5 is closed to stop the pump 13, and then the air valve 14 is opened to supply air with the compressor 15. The heat transfer liquid is fed into the reaction accelerating tank 6 through the port 64 and pushed out from the outlet 63.
When the heat medium liquid in the reaction accelerating tank 6 is exhausted, the compressor 15 is stopped, the opening/closing door 61 of the reaction accelerating tank 6 is opened, the valve 8 is closed, the connecting joint 7 is disconnected, and the alloy storage container 12 is removed from the reactor. It is taken out from the accelerator tank 6 and placed on a transport means such as a truck and sent out. In this example, the valve 9 provided in the alloy storage container 12 is closed. Further, the valve 8 is provided for the safety of the check valve 10, and can be omitted since the inside of the alloy storage container 12 will not become negative pressure under normal conditions. Furthermore, instead of the valve 8.9 or the check valves 10, 11, a single valve may be used. The reaction accelerator tank 6 is provided with a rail 65 at the bottom so that the alloy storage container 12 can be easily fed in and taken out, and the connecting joint 7 can be aligned naturally.

タンク１８からバルブ１９を介し熱媒液が補給される。In order to save energy, the hydrogen delivery station shown in FIG. The heat is used for other purposes by the radiator 17. In this case, the heat medium liquid is partially evaporated in the flash evaporator 16 and cooled, and accumulates at the bottom, and the accumulated heat medium liquid is sent by the pump 13 as described above. The flash evaporator 16 is supplied with heat medium liquid from a heat medium liquid supply tank 18 via a valve 19 .

ましい。The alloy storage container 12 may be a single piece as shown in FIG. 1, but if it is made thicker in order to store a large amount of hydrogen storage alloy, it will be necessary to increase the heat transfer rate without interfering with the flow of hydrogen. Even if a partition is provided, the reaction rate will be slow, so the configurations shown in FIGS. 2 and 3 are preferable.

The hydrogen inlet/outlet of each partial container 121 is connected to one hydrogen inlet/outlet pipe 12.
3, and at the end of the pipe 123 there is a connecting joint 7 for connecting the valve 22 to the hydrogen storage device and the hydrogen release device.
It consists of a configuration with By using such an alloy storage container 12, even if the overall amount of hydrogen storage alloy stored is increased, the thickness of each partial container 121 becomes thinner, and the hydrogen storage alloy inside can be quickly cooled and heated. Therefore, the reaction rate of hydrogen storage and release in the hydrogen storage device and the hydrogen desorption device becomes faster.

Reference numeral 2a denotes hanging engagement holes for lifting and lowering the entire alloy storage container 12.Three holes are provided in the circumferential direction to adjust the diameter of each partial container 121 by changing the hanging position. This is to correct the uneven distribution of the hydrogen storage alloy at the bottom of the container, which tends to occur when the hydrogen storage alloy is thick. Further, the notch 122b on the peripheral edge of the baffle plate 122 is a drain for preventing the heat medium liquid from being accumulated by the heat transfer tank 122 when the heat medium liquid is removed from the reaction accelerating tank 6. Instead of connecting each partial container 121 directly to the hydrogen inlet/output pipe 123, only one partial container 121 is connected to the hydrogen inlet/outlet pipe 123.
3, and a hydrogen flow pipe may be provided between that partial container 121 and other partial containers 121.

The heating medium liquid is fed into the reaction accelerating tank ε from the inlet 62 to heat the alloy storage container 12 and release hydrogen from the hydrogen storage alloy, and also flows up to the compressor 4 to release hydrogen from the hydrogen storage alloy. The hydrogen released by the tank is temporarily stored in a storage tank 3. Here, high-temperature cooling wastewater is preferably used as the heating heat medium liquid from the economic point of view, and the pump 13 feeds the heat medium liquid while releasing hydrogen from the hydrogen storage alloy, and the alloy storage container 12 The heat medium liquid whose temperature has been lowered by heating is sequentially discharged from the outlet 63.
なお、熱媒液の代わりに燃焼排ガス等を用いてもよい。Note that combustion exhaust gas or the like may be used instead of the heat transfer liquid.
