A small-scale seasonal energy storage system - comprising an electrolyser, metal hydride hydrogen store, and fuel cell - has been studied. According to the feasibility study, solid polymer electrolysers and fuel cells are the best options for the electrolyser metal hydride - fuel cell energy storage system. The round-trip efficiency of 30 % has already been demonstrated, and the next target is to reach the round-trip efficiency close to 40 %. The electrolyser - metal hydride - fuel cell systems are suitable for small-scale applications locating far away from electric grid, where high volumetric capacity is needed and safety aspects are appreciated
