Abstract

A hydrogen release and storage system ( 100 ) of the present invention includes a first hydrogen release and storage unit ( 100 A) composed of a first hydrogen compound member ( 101 A), a first container ( 102 A) that accommodates the first hydrogen compound member ( 101 A), a first heating apparatus ( 103 A) configured to heat an inside of the first container ( 102 A), a first cooling apparatus ( 104 A) configured to cool the inside of the first container ( 102 A), a first water supply apparatus ( 105 A) configured to supply water to the first container ( 102 A), a second hydrogen release and storage unit ( 100 B) composed of a second hydrogen compound member ( 101 B), a second container ( 102 B) that accommodates the second hydrogen compound member ( 101 B), a second heating apparatus ( 103 B) configured to heat an inside of the second container ( 102 B), a second cooling apparatus ( 104 B) configured to cool the inside of the second container ( 102 B) and a second water supply apparatus ( 105 B) configured to supply water to the second container ( 102 B).

First claim

What is claimed is:

1 . A hydrogen release and storage system comprising:
a first hydrogen release and storage unit composed of a first hydrogen compound member, a first container that accommodates the first hydrogen compound member, a first heating apparatus configured to heat an inside of the first container, a first cooling apparatus configured to cool the inside of the first container, a first water supply apparatus configured to supply water to the first container, a second hydrogen release and storage unit composed of a second hydrogen compound member, a second container that accommodates the second hydrogen compound member, a second heating apparatus configured to heat an inside of the second container, a second cooling apparatus configured to cool the inside of the second container, and a second water supply apparatus configured to supply water to the second container, and a switching apparatus configured to switch between a first state and a second state, the first state is a state where, in the first hydrogen release and storage unit, the first heating apparatus is driven and the first cooling apparatus and the first water supply apparatus are stopped, and in the second hydrogen release and storage unit, the second heating apparatus is stopped and the second cooling apparatus and the second water supply apparatus are driven, and the second state is a state where, in the first hydrogen release and storage unit, the first heating apparatus is stopped and the first cooling apparatus and the first water supply apparatus are driven, and in the second hydrogen release and storage unit, the second heating apparatus is driven and the second cooling apparatus and the second water supply apparatus are stopped.

2 . The hydrogen release and storage system according to claim 1 ,
wherein the first heating apparatus and the second heating apparatus are a same heating apparatus that is shared by the first hydrogen release and storage unit and the second hydrogen release and storage unit.

3 . The hydrogen release and storage system according to claim 1 ,
wherein the first cooling apparatus and the second cooling apparatus are the same cooling apparatus that is shared by the first hydrogen release and storage unit and the second hydrogen release and storage unit.

4 . The hydrogen release and storage system according to claim 1 ,
wherein the first water supply apparatus and the second water supply apparatus are the same water supply apparatus that is shared by the first hydrogen release and storage unit and the second hydrogen release and storage unit.

5 . The hydrogen release and storage system according to claim 1 ,
wherein a stoichiometric ratio between an element other than a hydrogen element that configures each of the first hydrogen compound member and the second hydrogen compound member and the hydrogen element is 1:1 to 3:4.

6 . The hydrogen release and storage system according to claim 5 ,
wherein the element other than the hydrogen element is boron.

7 . A hydrogen release and storage method in which the hydrogen release and storage system according to claim 1 is used as a hydrogen supply source, the method alternately comprising:
a first step of heating the inside of the first container so as to reach 150° C. or higher, releasing hydrogen from the first hydrogen compound member and supplying water to the inside of the second container while cooling the inside of the second container so as to reach lower than 150° C. and absorbing the hydrogen into the second hydrogen compound member; and
a second step of supplying water to the inside of the first container while cooling the inside of the first container so as to reach lower than 150° C., absorbing the hydrogen into the first hydrogen compound member and heating the inside of the second container so as to reach 150° C. or higher and releasing hydrogen from the second hydrogen compound member.

8 . An ammonia production apparatus comprising:
the hydrogen release and storage system according to claim 1 as a hydrogen supply source.

9 . A gas turbine comprising:
the hydrogen release and storage system according to claim 1 as a hydrogen supply source.

10 . A fuel cell comprising:
the hydrogen release and storage system according to claim 1 as a hydrogen supply source.

11 . A steel mill comprising:
the hydrogen release and storage system according to claim 1 as a hydrogen supply source.

12 . The hydrogen release and storage method according to claim 7 ,
wherein the inside of the second container is cooled so as to reach 80° C. or higher and lower than 150° C. in the first step.

13 . The hydrogen release and storage method according to claim 7 ,
wherein the inside of the first container is cooled so as to reach 80° C. or higher and lower than 150° C. in the second step.
