Abstract: The research progress of solid-state hydrogen storage technology is reviewed,including hydrogen storage materials,hydrogen storage devices and application status. Some hydrogen storage alloys have been successfully used in solid-state hydrogenstorage devices. The high-capacity reversible hydrogen storage materials under mild hydrogen absorption and desorption conditions is thefocus of current research and development. The optimized design of the hydrogen storage device effectively improves the rapid heattransfer characteristics and the safety performance. Hydrogen storage devices have been applied in the fields of distributed energy supplyand motor vehicles. However,it is still necessary to further realize the coordination of rapid response,safety,reliability,and highhydrogen storage density of the hydrogen storage system.
