Improved Hydrogen Storage Through Advances in Carbon

A group of researchers has developed a new method of layering graphite that could be used someday to efficiently and safely store hydrogen in a vehicle. If their preliminary findings hold up under more experimentation, carbon-based storage may have the most potential, among several technologies now being considered, to make fuel-cell vehicles commercially viable.
Published in the July 26 issue of the Proceedings of the National Academy of Sciences, the study claims that earlier research underestimated the potential capacity of carbon materials to store hydrogen. According to John Tse, one of the authors of the study and a professor of physics at the University of Saskatchewan, graphite nanomaterial can be layered to adsorb hydrogen gas at higher volumes and densities than previously thought possible.
