Method for gas storage, transport, and energy generation

摘要

The invention provides semi-clathrate hydrate compositions formed from water, a semi-clathrate hydrate forming compound and a gas. The semi-clathrate hydrate forming compounds can be ammonium salts, sulphonium salts, phosphonium salts or amines. The semi-clathrate hydrate compositions can be used to store gases including hydrogen, methane and carbon dioxide. Methods of manufacture of the compositions and their uses in energy storage and generation, and for the separation of gases are also described.
