GAS STORAGE METHOD AND SYSTEM, AND GAS OCCLUDING MATERIAL

WIPO Patent Application WO2000001980

A3

The gas storage method comprises a step of keeping a gas to be stored and an adsorbent in a vessel at a low temperature below the liquefaction temperature of the gas to be stored so that the gas to be stored is adsorbed onto the adsorbent in a liquefied state, a step of introducing into the vessel kept at the low temperature a gaseous or liquid medium with a freezing temperature that is higher than the above-mentioned liquefaction temperature of the gas to be stored, for freezing of the medium, so that the gas to be stored which has been adsorbed onto the adsorbent in a liquefied state is encapsulated by the medium which has been frozen, and a step of keeping the vessel at a temperature higher than the liquefaction temperature and below the freezing temperature.
