It changes every day and is not always constant. The controller C measures the amount of hydrogen generated during the day by the flow meter F1, and if it is determined that the hydrogen storage amount does not satisfy the planned hydrogen storage amount, the controller C recognizes the shortage amount and inputs it in advance. Based on the obtained power rate data, a time zone in which the power rate is the lowest is selected, and the water electrolysis apparatus E is activated so as to generate enough hydrogen to compensate for the shortage. If the commercial power G is set in three stages, for example, daytime, nighttime, and midnight, depending on the time zone, hydrogen is stored by preferentially selecting the cheapest time zone.

Further, when the hydrogen storage device is switched and used every day, the amount of hydrogen remaining in the hydrogen storage device is estimated by measuring the amount of hydrogen used the day before using the flow meter F2. The minimum time for operating the water electrolysis apparatus the next day can be obtained. For example, if the amount of hydrogen used on the previous day is 60% of the hydrogen storage amount, it is estimated that about 40% of the hydrogen remains in the hydrogen storage device. Hydrogen is needed to fill the storage volume. Therefore, it is possible to select the time with the lowest cost and perform the operation after recognizing the required operation time of the water electrolysis apparatus in advance.
