The reason why the dry hot rock reserves are not significantly affected by resource factors may be that the dry hot rock reserves are nearly 30 times of the global fossil energy, and the distribution of dry hot rock is relatively concentrated, especially in southwest, northeast and southeast coastal areas of China. Binary plants they draw hot water from underground and pass it through a secondary fluid with a lower boiling point than water. With any geothermal heat pump you have a heat source and a cold sink. Structural improvement and thermodynamic optimization of a novel supercritical CO2 cycle driven by hot dry rock for power generation. U.S. Energy Information Administration (EIA) (2022) Monthly Energy Review April 2022. Total Site Heat Integration benefiting from geothermal energy for heating and cooling implementations. 2. In this paper, the validity test method is structural validity, and the judgment methods generally include KMO sample measure (as shown in. In order to reduce emissions effectively, clean energy must be used to replace the traditional fossil energy. Contingent on the applications, geothermal energy can be employed for cooling and heating, power and But how does it actually work? Finally, some suggestions to promote the development of dry hot rocks in China are proposed.
