【Abstract】 1: Currently, hydrogen storage research is generally on-board-application oriented. However, the scenario of grid-scale hydrogen energy storage is remarkably different from on-board application, thus leading to diversity of performance requirements for hydrogen storage. In this paper, technical indicators of solid-state hydrogen storage systems and hydrogen storage materials for grid-scale hydrogen energy storage were studied. Firstly, performance requirements of hydrogen uptake and release for the hydrogen storage system were obtained by analyzing technical characteristics of electrolysis system and fuel cell system. Then, the technical targets of the solid-state hydrogen storage system and hydrogen storage materials for grid-scale application were put forwards, taking into account research and development status of hydrogen storage technology. The technical targets will guide research and development of solid-state hydrogen storage technology and materials for grid-scale application in the future.更多还原
