Carbon – the best solution for storing hydrogen?


A new method of layering graphite has been discovered, which could lead to storing hydrogen in a vehicle safely and efficiently.

The scientists who discovered the method claim carbon based storage may have the most potential to make fuel-cell vehicles commercially viable and that previous research has underestimated the potential capacity of the material to absorb and store hydrogen.

One of the scientists, John Tse, says graphite nanomaterial can be layered to absorb hydrogen at higher volumes and by controlling the spacing of layers of graphitic plates to maximize adsorption, a graphite storage system could meet the US Department of Energy’s milestones for both weight and volume of a hydrogen storage system.

The graphitic material is lighter than metal hydrides storage solutions currently being explored, and is relatively cheap to create.
