Therefore, even if there is no power supply from the outside, it is possible to obtain power and hydrogen and store them in the power / hydrogen supply station.
As for the electric power stored in the power storage unit, the electric power stored by the discharge may decrease.
Hydrogen stored in the hydrogen tank of the hydrogen storage section is unlikely to be released naturally.
Therefore, the electric power obtained by the first power generation device can be efficiently stored by using the electric power stored in the power storage unit for the short-term storage and by using the hydrogen tank for the long-term storage.
