在这项研究中，一个独立的能源系统，在寒冷地区的住宅使用的小型天然气CGS（热电联产），空气源热泵，蓄热罐，和GHB（气体水合物电池）。伽马-羟丁酸的热源是寒冷地区的环境空气和地热资源。对CO2水合物作为能源的热循环进行了实验研究。为了提高CO2水合物的生成速度，采用了氧化亚铁-石墨体系催化剂。寒冷地区的环境空气被用作伽马-羟丁酸形成过程（充电）的热源，地热换热器提供的热量被用于离解过程（放电）。使用地热热源，燃料消耗量减少了一半，因为伽马-羟丁酸中水合物形成的能力增加，充放电周期缩短，水合物形成空间的冻结速度降低。此外，当伽马-羟丁酸被引入到寒冷地区的房子，可再生能源的应用率在冬季为47-71%。伽马--羟丁酸的扩散可大大减少化石燃料的消耗和寒冷地区房屋释放的相关温室气体。

In this study, an independent energy system for houses in cold regions was developed using a small-scale natural gas CGS (cogeneration), air-source heat pump, heat storage tank, and GHB (gas hydrate battery). Heat sources for the GHB were the ambient air and geothermal resources of the cold region. The heat cycle of CO2hydrate as a source of energy was also experimentally investigated. To increase the formation speed of CO2hydrates, a ferrous oxide–graphite system catalyst was used. The ambient air of cold regions was used as a heat source for the formation process (electric charge) of the GHB, and the heat supplied by a geothermal heat exchanger was used for the dissociation process (electric discharge). Using a geothermal heat source, fuel consumption was halved because of an increased capacity for hydrate formation in the GHB, a shortening of the charging and discharging cycle, and a decrease in the freeze rate of hydrate formation space. Furthermore, when the GHB was introduced into a cold region house, the application rate of renewable energy was 47–71% in winter. The spread of the GHB can greatly reduce fossil fuel consumption and the associated greenhouse gases released from houses in cold regions.
