CO2 Storage in Natural-Gas-Hydrate Reservoirs Benefits From Associated Methane Production

Carbon dioxide (CO2) sequestration in natural-gas-hydrate reservoirs may offer stable long-term storage of a greenhouse gas with the additional benefit of methane (CH4) production. The sequestration process may thus offer large amounts of energy for the future while providing a more thermodynamically stable gas hydrate that is less sensitive to global temperature changes.
