Abstract

original image

Cold as ice: Inspired by a computational discovery, aqueous-valve-equipped nanocontainers fabricated from fine pieces of ice and single-walled carbon nanotubes enable the storage and release of pressurized hydrogen. Hydrogen at 1 GPa locked in these nanocontainers already corresponds to a weight storage efficiency of approximately 9 %, close to the 2015 target from the US Department of Energy.
