Energy functional materials
Under certain temperature and pressure conditions, hydrogen is stored in the hydrogen storage alloy in the form of solid metal hydride, and when the conditions are changed (heating or depressurization), the hydride can decompose to release hydrogen.
Using hydrogen storage alloys, which can reversibly absorb and release a large amount of hydrogen, solid storage of hydrogen can be workable.
