Techno-economic study of an innovative PV-hydrogen-biomass system for off-grid power supply

摘要

Hybrid Renewable Energy Systems (HRES) can be considered as an alternative energy option to provide off-grid power generation. In this study, the development of an innovative HRES based on the integration of hydrogen generation from biomass gasification, renewable energy power generation, hydrogen generation from water electrolysis, and a fuel cell providing combined heat and power was proposed. The Techno-Economic study of the proposed system was carried out in order to support the annual electricity demand of a selected household in shinchi-machi in Fukushima prefecture. As indicated by results of the model in this study, the total annual electricity generation by the proposed HRES was estimated about 48 MWh with a total annual hydrogen generation of 2.7 ton. The Levelized Cost of Energy of the system, including both electricity and thermal energy, was estimated at about 0.49 $/kWh.
