Molecular Fuel Tanks

Abstract
If a future hydrogen economy is to be realized, safe storage and delivery materials must be available. In his Perspective, Ward highlights the report by Rosi et al., whose porous metal-organic framework materials show promise for hydrogen storage. The materials do not yet show sufficiently high storage capacities for practical applications, but can easily be modified to increase uptake. Furthermore, their high crystallinity allows the hydrogen absorption sites to be identified. This knowledge may be helpful in designing future hydrogen-storage materials.
