Overview of Geothermal Power Generation and Joint Power Generation With Other New Energy Sources

Abstract

Geothermal resources are abundant and widely distributed in China. With the emergence of energy shortage and environmental deterioration, geothermal energy, as a renewable and clean energy source, has been widely focused and used in power generation to reduce the emission of pollutants, mitigate the greenhouse effect caused by fossil fuels such as coal and realize the optimization of energy structure. This paper introduced the working principle of geothermal steam power generation technology, geothermal hydropower generation technology, dry heat rock power generation technology and magma power generation technology, and compared them in terms of scope of application, power generation efficiency, power generation cost, advantages and disadvantages, etc. In addition, joint power generation technology with solar power and biomass power was suggested, the problems of geothermal power generation were points out, in order to provide a theoretical basis for the practical application of geothermal energy in China and even in the world.
