According to the development plan proposed by the National Development and Reform Commission, the geothermal heating area in China will reach 1.6 billion m2 by 2020. Geothermal power generation capacity will reach 530 MW, and the annual utilization of geothermal energy in the Beijing-Tianjin-Hebei region will be equal to 20 million standard coal. This is the first national plan promoting the development of geothermal energy.
China has abundant geothermal resources and great market potential. Speeding up the development of geothermal energy is important for energy saving and environmental protection. Heat pump technology has been applied mainly for developing the shallow type geothermal energy, with an annual increase of more than 30% since 2004. By the end of 2015, the total heating/ cooling area using shallow and hydrothermal type geothermal energy reached 392 million m2 and 102 mil-lion m2, respectively.
