抄録

When the mixed fluid of gas and water is pressurized and cooled to a given pressure and temperature, the generation of a gas-hydrate occurs. By heating, a very high pressure is obtained from the dissociated gas from the gas-hydrate. The purpose of this study is to investigate the operation of a high-pressure gas engine generator for distributed power supplies using the high pressure obtained though the dissociation of a gas-hydrate. A gas-hydrate functions as a working fluid and as a form of energy storage. However, until now, an actuator that uses the dissociation inflation characteristics of a gas-hydrate has not been examined. Therefore, the generation rate of CO<SUB>2</SUB> hydrate and the quantity to be stored from the dissociation expansion energy of CO<SUB>2</SUB> hydrate were investigated. As a result, when 1 m<SUP>3</SUP> of water was used to generate CO<SUB>2</SUB> hydrate for 480 minutes, the result was that electric power corresponding to approximately 45% of the daily power consumption (4.5 kWh of generator outputs) of an individual house can be stored.
