Abstract
We report a very fast method for hydrogen clathrate production. The formation of hydrogen clathrate from H 2 gas and ice-Ih at 77 – 273 K occurs at least 100 times faster compared to the reaction with water. This effect is probably the result of a partial penetration of hydrogen into the ice-Ih body, which favors clathrate formation. With the ice method, the ice - Ih ∕ 48 H 2 * 136 H 2 O system can quickly trap and release up to 3.77 mass % of hydrogen, which gives it an advantage over other chemical-bonding hydrogen storage technologies. New data on the hydrogen-water phase diagram are presented and discussed.Keywords
