- W2566826939 abstract "Geothermal and other renewable energy resources are becoming attractive solutions for clean and sustainable energy needs of China. There are rich geothermal resources in China which have been proven equivalent to 8.6×10 15 tons of coal. However, the main way of utilizing geothermal energy is district heating in some big cities in north China. The utilizing scale is quite small and still has certain gap with the size of the market. The main purpose of this study is to investigate the potential of geothermal energy market in China including calculation of economic efficiency and the environmental impact on northern China. Based on the characteristics of low temperature geothermal resources, we built a comprehensive evaluation system. First, we set up a file to do basic financial evaluation of geothermal engineering operational data for Xianyang, Xiongxian and Tianjin; second, we used super-efficient DEA model to evaluate the economic efficiency in northern China from the large regional perspective; Then, we used LCA method to calculate the environmental impact potentials during geothermal development process; Catastrophe progression method was finally used to integrate economic and environmental indicators objectively and systematically, which can be used to predict the potential of the geothermal energy market in China. The results show that (i) The geothermal heating project is economically viable in northern China. Economic analysis suggested that average payback period is from four to eight years. Compared to the heat pump, hydrothermal geothermal resources is more efficient; (ii) Geothermal energy contributes a lot to greenhouse gas reduction target, although about 95.98% of total environmental impact occurs in the construction period; (iii) All the efficiency index is more than 0.8, which means there is a huge potential of geothermal energy market in China." @default.
