Abstract

The community system includes a hydrogen source, a hydrogen storage, an FC power generating facility, a house group that uses hydrogen supplied from at least one of the hydrogen source and the hydrogen storage, and a management system that manages hydrogen in the community system. The management system manages hydrogen possession allocated to each house in the house group.

First claim

What is claimed is:

1. A community system that uses hydrogen, comprising:
a hydrogen source;
a hydrogen storage storing hydrogen supplied from the hydrogen source;
a house group with multiple houses that use hydrogen supplied from at least one of the hydrogen source and the hydrogen storage; and
a management system that manages hydrogen in the community system, wherein
the management system manages hydrogen possession allocated to each house in the house group.

2. The community system according to claim 1 , wherein
the hydrogen storage includes one hydrogen storage unit provided in the house group, and
hydrogen possession at each house in the house group is stored in the hydrogen storage unit in the house group.

3. The community system according to claim 2 , wherein
the hydrogen storage unit in the house group is connected to a different hydrogen storage unit in a different house group through a pipeline.

4. The community system according to claim 1 , wherein
the hydrogen storage includes multiple hydrogen storage units allocated to corresponding houses in the house group, and
hydrogen possession at each house in the house group is stored in the hydrogen storage unit allocated to the same house.

5. The community system according to claim 4 , wherein
the multiple hydrogen storage units in the house group are connected to each other through a pipeline and are connected to multiple different hydrogen storage units in a different house group through the pipeline.

6. The community system according to claim 1 , wherein
the management system reflects, in the hydrogen possession at each house in the house group, a hydrogen transfer amount transferred from the same house.

7. The community system according to claim 6 , wherein
when hydrogen is transferred from each house in the house group, the management system moves hydrogen of the hydrogen transfer amount to the hydrogen storage provided in the house group.

8. The community system according to claim 6 , wherein
when hydrogen is transferred from each house in the house group, the management system hands over a hydrogen ownership without actually moving hydrogen.

9. A management method of managing a community system comprising a hydrogen source, a hydrogen storage storing hydrogen supplied from the hydrogen source, and a house group that uses hydrogen supplied from at least one of the hydrogen source and the hydrogen storage, the method comprising:
a management step of managing hydrogen possession allocated to each house in the house group, wherein
the management step comprises a step of reflecting, in the hydrogen possession at each house in the house group, a hydrogen transfer amount transferred from the same house.

10. The management method according to claim 9 , wherein
the management step comprises a step of moving hydrogen of the hydrogen transfer amount to the hydrogen storage provided in the house group when hydrogen is transferred from each house in the house group.

11. The management method according to claim 9 , wherein
the management step comprises a step of handing over a hydrogen ownership without actually moving hydrogen when hydrogen is transferred from each house in the house group.
