Composition and method for hydrogen storage

摘要

A method for hydrogen storage includes providing water and hydrogen gas to a containment volume, reducing the temperature of the water and hydrogen gas to form a hydrogen clathrate at a first cryogenic temperature and a first pressure and maintaining the hydrogen clathrate at second cryogenic temperature within a temperature range of up to 250 K to effect hydrogen storage. The low-pressure hydrogen hydrate includes H2O molecules, H2 molecules and a unit cell including polyhedron cages of hydrogen-bonded frameworks of the H2O molecules built around the H2 molecules.
