Elucidating the mechanisms of self-preservation and control of dissociation of gas hydrates is crucial for developing technologies facilitating high-stability and long-term storage of natural gas using gas hydrate crystals. Direct measurements of the dissociation behavior of pressurized and nonpressurized methane hydrate grains in a temperature ramping test were conducted. We revealed that a pressurized process is effective for enhancing self-preservation and that it is useful to store methane gas while maintaining a submillimeter-sized hydrate material under high temperature conditions.
