To promote the large-scale development of geothermal power generation in China

the data of geothermal resources in China is collected and arranged in this paper. The characteristics of geothermal resources

relevant policies and development status of geothermal power generation in China are summarized. Five typical geothermal power generation technologies are reviewed

which are steam Rankine cycle

flash cycle

organic Rankine cycle

Kalina cycle and full-flow power system. Key factors affecting the development of geothermal power generation are discussed and summarized. The geothermal resources in China are mainly medium-to-low temperature geothermal energy(below 150 ℃)

and the organic Rankine cycle and Kalina cycle have greater development space in the field of geothermal power generation. Higher geothermal temperature

larger flow rate

higher geothermal fluid dryness and better water quality conditions will result in lower local ambient temperature

higher well completion rate and greater development potential of geothermal power generation. Abundant water resources and high on-grid price and investment subsidies are also conducive to the growth of geothermal power generation industry.
