Benefits Analysis and Utilization Strategy for Development of Shallow Geothermal Energy: A Case Study of Tianjin

As a renewable energy, shallow geothermal energy has received extensive concerns in China, and is regarded as an important means to relieve the pressure in energy supply, meet the greenhouse gas control obligations and establish a low-carbon economy system. In recent years, a series of policies and regulations for promoting the utilization of shallow geothermal energy has been issued. This paper firstly makes an analysis of the patterns and the growing trend of shallow geothermal energy utilization, and then establishes the analysis paradigms of the economic, environmental and social benefits of its utilization, taking Tianjin as a case. Finally, a policy system to promote the utilization of shallow geothermal energy is proposed.
