Review of Technical Analysis and Application Status of Hydrogen Energy Storage System

Under the background of "dual carbon" goal, the development of hydrogen energy storage technology is helpful to slow down carbon emissions and promote the large-scale utilization of renewable energy. Through in-depth summary of the development status of hydrogen and hydrogen energy, key technologies of hydrogen energy storage system and their application status, three hydrogen production methods including wind power hydrogen production, photoelectric hydrogen production and electrolytic water hydrogen production are analyzed. Four hydrogen storage methods, including high pressure gaseous hydrogen storage, low temperature liquid hydrogen storage, metallic organic hydrogen storage and organic liquid hydrogen storage, and hydrogen power generation technology, and the application status of hydrogen storage system in renewable energy, natural gas, hydrogen fuel cells, and clean utilization of fossil energy are described, in order to provide reference for related research in the field of hydrogen energy storage.
