Abstract
At introductory stage, the hydrogen energy is promised to be provided for fuel cell vehicles (FCV) as well as proton exchange membrane fuel cell-combined heat and power plant (PEFC-CHP) in residential areas for accelerating the hydrogen infrastructures. The objective of this paper is to clarify that the hydrogen provision method for the FCV and the PEFC-CHP affects the primary energy consumption reduction comparing with the hydrogen provision for only FCV. The operation method of the PEFC by using demand data for electric power and hot water in Japanese residential areas was numerically studied. The hydrogen production process was numerically studied, and benefit of hydrogen energy system was compared with the conventional energy supply system. The hydrogen provision for the FCV and the PEFC-CHP was better than only for FCV provision system from the energy consumption point of view.
