In one embodiment of the present disclosure, a process for cyclic dehydrogenation and rehydrogenation of hydrogen storage materials is provided. The process includes liberating hydrogen from a hydrogen storage material comprising hydrogen atoms chemically bonded to one or more elements to form a dehydrogenated material and contacting the dehydrogenated material with a solvent in the presence of hydrogen gas such that the solvent forms a reversible complex with rehydrogenated product of the dehydrogenated material wherein the dehydrogenated material is rehydrogenated to form a solid material containing hydrogen atoms chemically bonded to one or more elements.
