| Outline of Final Research Achievements |
CO2 hydrate is formed and dissociated by a slight temperature difference in the ambient temperature, it has the unique property of absorbing and releasing large amounts of CO2. Therefore focusing on this characteristic, for power generation by driving the gas turbine by CO2 gas pressure released, the attempted development of a power generator (CO2-H generator) that uses natural energy as a heat source.
In this study, experiments of formation and dissociation of CO2 hydrate were caried out. Then the feasibillity of the cold heat recovery by small power generation system were investigated. Based on the results of these studies, numerical analyses of the CO2-H generator were caried out. As a result, the relationship between the amount of electrical energy, which was stored in 1 m3 water, and heat source temperature was revealed.
