Abstract: The method for controlling an organic hydride generation system includes controlling potentials in an anode electrode and a cathode electrode such that a potential change in an electrode having a higher deterioration rate among the anode electrode and the cathode electrode included in an electrolytic bath is smaller than a potential change in an electrode having a lower deterioration rate.

Abstract: A device for supporting deterioration determination includes: a first calculating unit that: acquires a dataset including a plurality of reaction condition values and a voltage in a first period and in a second period; and uses the dataset and a calculation formula to calculate a parameter group of the calculation formula for each period; a second calculating unit that substitutes a reaction condition value in the calculation formula in which the parameter group is incorporated to calculate a comparison target value for each period; and a third calculating unit that calculates a deterioration degree of the water electrolysis module based on a difference between a first comparison target value and a second comparison target value.

Abstract: A hydrogen production system includes a hydrogen production facility and a management server. The management server includes an operation plan creation unit and an operation plan output unit. The operation plan creation unit creates an operation plan for the hydrogen production facility. The operation plan output unit outputs data including the operation plan created by the operation plan creation unit. The operation plan creation unit creates an operation plan for the hydrogen production facility including a demand response possible amount for each unit time based on a demand response consideration for each unit time determined in advance.

Abstract: A method for controlling a hydrogen generation system includes controlling the potentials of an electrode for oxygen generation and an electrode for hydrogen generation included in an electrolyzer so that the potential change is smaller in the electrode for oxygen generation or the electrode for hydrogen generation having a larger deterioration rate than in the electrode having a smaller deterioration rate.
