Therefore, even when the first storage unit 17a or the like is in a fully charged state, it is possible to convert surplus electric power into hydrogen and store a large amount of energy.
If the power supply from the first power generation device 11 is not sufficient and the power stored in the first power storage unit 17a or the like is not sufficient, the hydrogen in the storage units (hydrogen tank 21d, liquid tank 21i) is used as power.

In this case, one first electric power / hydrogen supply station 10a can independently supply electric power to one condominium or the like without supplying electric power from a commercial power source. In addition, since the numerical values of the specifications (capacity, pressure, etc.) of each part are relatively small, it is easier to apply to each organization when installing the hydrogen tank 21d etc. in the building 25 compared to the form in which the numerical values of the specifications of each part are large.
