Abstract

Shallow geothermal energy and hot dry rock have the most utilization potential among geothermal energy. The former is used to offer indoor heating or cooling to reduce the country's energy demands, and the latter is used to generated electricity to increase the national renewable energy supply. Both of them have tremendous potentials and are environmentally friendly, and the development technology named ground source heat pump and enhanced geothermal systems share some similarities. This paper compares the basic concept, resource potential, energy-saving effects, economic benefit and environmental impacts between shallow geothermal energy and hot dry rock, discussing their advantages and disadvantages and development prospects. Based on the characteristics of geothermal resources in China and the national planning on energy development, geothermal development is suggested to go deeper in the future.
