| Outline of Final Research Achievements |
In this study, a carbon dioxide hydrate power generation system was investigated. The hydrate has a unique property which formation and dissociation is occured due to a slight temperature difference around normal temperature and a large amount of carbon dioxide is absorbed and released .
In this study, I carried out experiments and numerical analysis on the effect of Cyclopentan as a formation promotor on the energy storage rate and energy storage capacity of the power generation system.
As a result of the experiment, it was revealed that the rate of hydrate formation was increased seven times when the formation promoter was used. In addition, as a result of analysis on a detached houses introdused the power generation system, it was revealed that the reduction amount of purchased electricity is increased by 1.8 times when using the formation promotor.

| Academic Significance and Societal Importance of the Research Achievements |
二酸化炭素ハイドレートに生成促進剤を加えると相平衡圧力が高温かつ低圧力側にシフトすることは既に知られていたが，生成速度への影響は不明だった．本研究では，生成速度が増加することを実験的に明らかにした点で学術的意義がある．また，生成速度の増加が発電システムに及ぼす影響を解析的に明らかにした．これは未利用エネルギーを活用した新たな発電システムの実現性を高めた点で社会的意義がある．
