Hope Revived for Storing Hydrogen in Nanocarbon

by Philip Ball Nature Materials Update, 21 Jul 2005 Could carbon nanostructures really be used to store hydrogen, for example in fuel-cell-powered electric vehicles? This enticing prospect was suggested eight years ago, when high storage densities were reported in carbon nanotubes. But researchers have struggled subsequently to reproduce those findings, and neither experiments nor theoretical calculations have convincingly shown that the target storage capacity specified by the US Department of Energy for practical applications can be reliably reached.
