The CO_2 hydrate is a potential phase change material for the thermal energy storage. High-pressure conditions are generally required for the production of the simple CO_2 hydrate, while CO_2+hydrocarbon hydrates can generate under moderate pressure conditions. The enthalpy of fusion depends on the partial pressure of CO_2 and hydrocarbons. Some surfactants and ionic liquids are effective in the suppression of supercooling during the CO_2 hydrate production.

CO_2水合物是一种潜在的热能储存相变材料。简单CO_2水合物的生成一般需要高压条件，而CO_2+烃类水合物在中等压力条件下即可生成。熔化焓取决于CO_2和碳氢化合物的分压。一些表面活性剂和离子液体可以有效抑制CO_2水合物生产过程中的过冷。
