A fluid mixture of gas and water, pressurized and cooled to a certain pressure and temperature, gas hydrate is produced. By heating the gas hydrate after the formation, extremely high pressure gas can be obtained by hydrate dissociation. This study aims the pressure obtained by dissociation of gas hydrate, drives a high-pressure gas engine generators as distributed power. Gas hydrate has a function of the energy storage capabilities and the working fluid. However, the actuator using the expansion properties dissociation of gas hydrate does not have any examples for previous discussion. This paper focuses on CO_2 hydrate. Then the expansive energy dissociation of CO_2 hydrate formation rate of hydrates storage capacity is investigated. As a result, it is proved an electric power corresponding to approximately 45% of the daily power consumption (4.5 kWh of generator outputs) of an individual house is stored, when 1 m^3 of water is used to generate CO_2 hydrate for 480 minutes.
