Hydrogen storage is one of the main problems, to catalyse wide hydrogen use in transportation, technology and energetics. Composites involving nanostructured carbon species could be the solution for hydrogen storage problem because of their promising surface/volume relation. Not only catalysis and gas sensing on graphene basis should be considered, but also metal decorated graphene structures for use in hydrogen storage should be an active field for research and development. Heat conductivity and large surface area of graphene-like materials can endorse research for hydrogen storage in low pressures and close to room temperature (RT) conditions - increasing possibility for RT-range devices in hydrogen energetics. For increased hydrogen storage investigations, we propose metal intercalated graphene structures, acquired during synthesis of graphene sheets.
