ー Vol.46 No.11(1994) p22、等）。2. Description of the Related Art Conventionally, there has been a method of circulating a heat medium such as water vapor for transporting heat over a long distance. Furthermore, in recent years, a method utilizing a chemical reaction has been proposed to suppress the heat loss of heat transport. Among them, the most prominent one utilizes hydrogen and a hydrogen storage alloy, and a number of methods have been proposed (Japanese Patent Publication No. 3-16596, Japanese Patent Publication No.
No. 41271). This long-distance heat transfer method using hydrogen and a hydrogen storage alloy is one of the “New Sunshine Projects” implemented by the Ministry of International Trade and Industry of Japan, the “Global Energy Network System” (Eco Energy City System).

Two types of hydrogen pipelines will be installed, connecting high-pressure hydrogen pipelines and low-pressure hydrogen pipelines, connecting the heat source and the heat utilization site. In the heat source, when a hydrogen storage alloy suitable for the temperature of heat is selected and heat is applied thereto, the hydrogen storage alloy releases the stored hydrogen to a high-pressure hydrogen pipeline. The alloy that has finished releasing hydrogen is connected to a low-pressure hydrogen pipeline,
It absorbs low-pressure hydrogen and generates heat. This heat is lower than the initial heat temperature due to the pressure difference between the high and low pressure hydrogen pipelines. This heat is used again for another hydrogen storage alloy or the like, or is released to the atmosphere. By repeating this, the pressure of the hydrogen in the low-pressure hydrogen pipeline is increased by the heat of the heat source, and is pumped into the hydrogen in the high-pressure hydrogen pipeline. The hydrogen in the high-pressure hydrogen pipeline flows to a heat utilization site, where it is absorbed by another hydrogen storage alloy and generates heat, which is used for heating and hot water supply. When the hydrogen storage amount of the hydrogen storage alloy reaches saturation, the hydrogen is released to the low-pressure hydrogen pipeline. There is endotherm accompanying this release, which is used for cooling. The hydrogen released to the low-pressure hydrogen pipeline returns to the heat source side, is pressurized again by heat, and is pumped to the high-pressure hydrogen pipeline. By repeating the above, heat is transported over a long distance.

行うことは、事実上困難であった。The above-mentioned method is a very high-efficiency method. However, two types of hydrogen pipelines, a high-pressure hydrogen pipeline and a low-pressure hydrogen pipeline, connecting a heat source and a heat utilization site are used. Because of the need for facilities, large-scale civil works and extensive land must be expropriated.
That is a huge expense. Therefore, it was practically difficult to do it on a small scale.

Embodiment 1 FIG. 1 is a conceptual view of a hydrogen transport trailer according to a first embodiment of the present invention. In FIG. 1, a hydrogen transport trailer 10 includes a low-pressure hydrogen storage container 12 containing a first hydrogen storage alloy (hereinafter abbreviated as MH1) 11 and a second hydrogen storage alloy having an equilibrium hydrogen pressure higher than that of MH1. (Hereinafter abbreviated as MH2). Two high-pressure hydrogen storage containers 14 having a built-in 13 are mounted. These low-pressure hydrogen storage container 12 and high-pressure hydrogen storage container 14 include:
A hydrogen supply / discharge connector 15 is provided.
1 or MH213 can be supplied with hydrogen or released. The hydrogen supply / discharge connector 15 has a known valve structure that is closed unless connected to a hydrogen supply / discharge connector such as another hydrogen storage container.
The high-pressure hydrogen storage container 14 is closed when the hydrogen supply / discharge connector 15 is not connected. Further, the hydrogen trailer has a pump 16 and a circulating water channel 17 provided along the outer walls of the low-pressure hydrogen storage container 12 and the high-pressure hydrogen storage container 14. The water (not shown) pumped from the circulating water inlet 18 by the pump 16 heats or cools the low-pressure hydrogen storage container 12 and the high-pressure hydrogen storage container 14 and is discharged from the circulating water outlet 19. The device that circulates water in the circulation channel 17 in this way serves as a means for stabilizing the temperature of the hydrogen storage containers 12 and 14. This circulating water may be tap water or the like, but if river water or sewage is used, the water temperature is stable and inexpensive. In the present embodiment, a circulating water system is used, but other temperature stabilizing means such as a radiation fin or a heat pipe may be used.

Collected in H341. At this time, since the temperature of the MH111 decreases due to endotherm during the release of hydrogen and the reaction speed decreases, river water is passed through the circulation channel 17 to maintain the temperature of the MH111 at about 25 ° C. When the MH11 has completely released hydrogen, the valve 44 is closed, and steam at 160 ° C., which is waste heat of the factory, is passed through the heat exchanger 42 through the steam inlet 45. Heat exchanger 4
The steam passing through 2 heats MH 341 to 150 ° C. and is discharged from steam outlet 46. At this time, MH34
The high pressure hydrogen of 3 MPa released from 1 is stored in the MH 213 in the high pressure hydrogen storage container 14 by operating the valve 47. Also, at this time, the temperature of the MH213 rises due to the heat generated at the time of occlusion, and the reaction speed decreases. Therefore, river water is passed through the circulation channel 17 to maintain the temperature of the MH213 at about 25 ° C. When the MH213 is filled with hydrogen, the valve 47 is closed and the hydrogen supply connector 15 is disconnected. The separated hydrogen transport trailer 10 transports high-pressure hydrogen to urban areas.

The method of utilizing heat in an urban area converts and uses the pressure of hydrogen into heat by a completely opposite operation to the method of recovering exhaust heat in a factory area. Therefore, it is very similar to the configuration of FIG. The pressure-heat converter 36 is composed of a hydrogen storage container 53 containing a hydrogen storage alloy (hereinafter abbreviated as MH4) 51 and a heat exchanger 52, and valves 54 and 57.

る。First, the valve 54 is operated, and the high-pressure hydrogen stored in the MH213 in the high-pressure hydrogen storage
Absorb in H451. At this time, since the temperature of the MH213 decreases due to the endotherm during the release of hydrogen and the reaction rate decreases, the river water is passed through the circulation channel 17 to maintain the temperature of the MH213 at about 25 ° C. Therefore, the pressure of high-pressure hydrogen is about 2MP
a. The MH 451 absorbs the high-pressure hydrogen and reaches about 50 ° C. to generate heat. The heat is exchanged with the water put in the heat exchanger 52 from the water inlet 55 and is taken out from the water outlet 56 as warm water. This hot water is used in a heating device such as a fan coil. When the MH 213 has completely released hydrogen, the valve 54 is closed, and the hydrogen stored in the MH 451 is now stored in the MH 111 in the low-pressure hydrogen storage container 12 by operating the valve 57. Also at this time, the temperature of the MH111 rises due to the heat generated during the occlusion of hydrogen, and the reaction speed decreases. Therefore, the river water is passed through the circulation channel 17 to maintain the temperature of the MH111 at about 25 ° C. For this reason, the pressure of hydrogen stored by the MH111 becomes low-pressure hydrogen of about 0.2 MPa. M
H451 releases this low pressure hydrogen to about 4 ° C,
Absorbs heat. The heat is exchanged with the water put in the heat exchanger 52 from the water inlet 55 and is taken out as cold water from the water outlet 56. This cold water is used in a cooling device such as a fan coil.

Thus, the cycle of high-pressure hydrogen transport from the factory zone to the urban area and low-pressure hydrogen transport from the urban area to the industrial zone are repeated. The trailer of the present embodiment described above is supposed to be 20 t in the regulation, and heat transfer of 480 Mcal is possible by storing 8 t of the hydrogen storage alloy in each of the low-pressure hydrogen storage container and the high-pressure hydrogen storage container.
