Hydrogen storage is one of the main problems, to push forward wide hydrogen usage in transport technology an energetics. Composites involving nanostructured carbon species could help to find 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. Mainly heat conductivity and large surface area of graphene-like materials can endorse research for hydrogen storage in low pressures and close to RT conditions - increasing possibility for RT-range devices in hydrogen energetics. For increased hydrogen storage investigations, we propose Rare-earth metal intercalated graphene structures, acquired during synthesis of graphene sheets.
