Technology: Hydrogen and hydrates
Ferdi Schüth1
Abstract
It's a potentially explosive issue. How can hydrogen be stored cleanly, efficiently and, above all, safely? One answer would appear to be: take a cage made of water, and add just a little organic solvent.
Finding cheap and easy storage methods will be crucial to establishing hydrogen as a fuel of the future. Clathrates — in which hydrogen molecules are encapsulated or 'occluded' in a cage-like lattice of water molecules — are one option, but until now the pressure required to maintain the stability of such systems has been too high.
