Hydrogen is considered to be the critical path for energy transformation,and deep decarbonization in industry and transportation aspects.This paper reviews the present status and development trend of solid-state hydrogen storage technology,summarizes the main technical routes such as physical adsorption,chemical hydrogen storage materials,and metal hydride materials,and introduces the development goals of key technical parameters such as gravimetric hydrogen storage density,volumetric hydrogen storage density,cycle life and system cost proposed by the U.S.Department of Energy and other institutions.The existing technical and economic problems,as well as the improvement directions are proposed.The application scenario and potential of solid-state hydrogen storage are analyzed,and some suggestions on future technology development,system integration optimization and application direction are put forward.
