| Outline of Final Research Achievements |
Temperature-pressure phase diagram of carbon dioxide gas-hydrate is confirmed by experiment, the theoretical heat cycle obtained from this diagram was clarified. Moreover, in the heat cycle described in the top, the response time of phase change is indefinite. Therefore, it clarified by experiment also about reaction velocity. Although the phase change of gas-hydrate consists of dissociative reaction and generation reaction, this result of study has realized improvement in the speed of the generation response that requires long time.

| Academic Significance and Societal Importance of the Research Achievements |
二酸化炭素ハイドレートによるエネルギー貯蔵密度とエネルギー輸送量の実験を行い、エネルギー貯蔵密度が見積もりできるようになった。この結果、十数度の温度差で得られる二酸化炭素ハイドレートによるエネルギー貯蔵量と、ガスハイドレート熱サイクルを示すことができるようになった。大気の熱と未利用廃熱で駆動する電力変換システムは、これまでにないエネルギー変換経路である。
