Abstract

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

First claim

What is claimed is:

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

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

3 . The hydrogen release and storage system according to claim 2 ,
wherein an element other than the hydrogen element is boron.

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

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

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

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

8 . 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 hydrogen release step of heating the inside of the container so as to reach 150° C. or higher and releasing hydrogen from the hydrogen compound member, and
a hydrogen absorption step of supplying water to the inside of the container while cooling the inside of the container so as to reach lower than 150° C. and absorbing the hydrogen into the hydrogen compound member.

9 . The hydrogen release and storage method according to claim 8 ,
wherein the inside of the container is cooled so as to reach 80° C. or higher and lower than 150° C. in the hydrogen absorption step.
