Hydrogen storage for off-grid power supply

摘要: The use of intermittent renewable energy sources for power supply to off-grid electricity consumers depends on storage technology guarantee continuous supply. Potential applications storage-guaranteed systems range from small installations remote telecoms, water-pumping and single dwellings, farms whole communities whom grid connection is too expensive or otherwise infeasible, industrial, military humanitarian uses. In this paper we explore some the technical issues surrounding hydrogen storage, in conjunction with a PEM electrolyser fuel cell, when source intermittent, most typically solar photovoltaic. We advocate metal-hydride compare its density that Li-ion battery concluding significantly smaller package possible storage. A simple approach match output photovoltaic array an presented. properties required material interface cell are discussed detail. It concluded relatively conventional Mischmetal-based AB5 alloys suitable application.
