Fundamental examination on the dissociation and expansion characteristics of CO2 hydrate using the gas-hydrate generator

Focused on the differential pressure at the time of generation of gas hydrate dissociation, we develop a power generator by the high-pressure gas. CO₂ hydrate generates from fluid mixture of pure water and CO₂. Furthermore, heating of CO₂ hydrate will generate the high pressure gas by dissociation. Filling 3 MPa CO₂ gas poured into 50ml water as an initial condition, repeating the cooling and heating between -5 °C and 30 °C it, can be obtained continuously a pressure differential of about 0.7 MPa.
