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.

Abstract: A method for generating carbon monoxide includes: a generation step of generating carbon monoxide by supplying carbon dioxide to a first material containing a first element included in elements of group 11 and a second element included in elements of groups 8 to 10, 12, and 13; and a reduction step of reducing the second element oxidized in the generation step by supplying hydrogen to a second material containing the oxidized second element and the first element. The generation step and the reduction step are repeated a plurality of times.

Abstract: An organic hydride generation system includes an electrolytic bath, a main power supplier, an auxiliary power supplier, a detector to detect a voltage of the electrolytic bath, a potential of an anode electrode, or a potential of a cathode electrode, and a controller to control the supply of power to the electrolytic bath. When it is detected that the voltage or the potential has changed to a specified value during operation stop of the organic hydride generation system in which the power from the main power supplier is not supplied to the electrolytic bath, the controller controls the auxiliary power supplier so as to supply the power to the electrolytic bath.

Abstract: A hydrocarbon production apparatus includes a synthesis gas production unit structured to produce a synthesis gas containing carbon monoxide and hydrogen by using carbon dioxide and hydrogen, a hydrocarbon production unit structured to produce a hydrocarbon by using the synthesis gas, and a first separator structured to separate a recycle gas containing a light hydrocarbon having 4 or less carbon atoms from an effluent from the hydrocarbon production unit. The synthesis gas production unit is structured to receive supply of the recycle gas and also use the recycle gas for production of the synthesis gas.
