CO2 hydrates is a promising storage method for high-density, high-pressure CO2 gas because it is formed at around 0°C and dissociates at 10-20°C under high pressure of several MPa. As a way to increase the storage efficiency of the proposed CO2 hydrate storage system, if the temperature conditions during CO2 hydrates generation can be shifted to the room temperature side, more CO2 hydrates can be generated with less cold heat, and energy-efficient high-pressure CO2 gas storage will become possible. In this study, we report the results of a CO2 hydrates generation experiment in which the generation temperature was shifted to the room temperature side when cyclopentane was added.
