Geothermal power generation

as one of the main ways to develop and utilize geothermal resources

is of great significance to promote the low-carbon and clean energy structure and the realization of the “dual carbon”. Firstly

the development history of geothermal resources in the world is analyzed. Then

main geothermal power generation technologies such as dry steam power generation

flash steam power generation

binary cycle power generation and wellhead power generation technology are overviewed. On this basis

the hot dry rock power generation

thermovoltaic power generation

supercritical CO2 cycle power generation

combined power generation technology and multi-energy eomplementary power generation technologies such as geothermal-solar

geothermal-wind

geothermal-biomass

and geothermal-ocean energy

are elaborated in detail. Finally

combining with the current situation and existing problems of geothermal power generation in China

some suggestions for the development of geothermal power generation are put forward

to provide reference for the future development of geothermal power generation.
