Global geothermal is "hot" green future will come

How does the development of geothermal industry take advantage of the trend

Clarify the development route of geothermal energy and explore "multiple" paths for the utilization of geothermal energy. It is suggested that all provinces and cities should build geothermal key projects according to local conditions according to the characteristics of geothermal resources and actual energy demand, and put forward specific and feasible safeguard measures, further refine the planning and implementation of geothermal industry development routes based on the current guiding policies, and position geothermal energy as one of the key factors in achieving climate goals. The benefits of geothermal energy should be promoted to provide opportunities to use it in a sustainable and climate-friendly way, and policy development should focus on multiple ways to promote clean power generation, clean heating and cooling.

Step up resource evaluation efforts to develop and utilize all available geothermal energy. Detailed investigation and fine evaluation of geothermal resources in key areas should be carried out, and special attention should be paid to the "2+26" cities in the Beijing-Tianjin-Hebei air pollution transmission channel and the resource evaluation of 11 cities in the Fenwei Plain at this stage. The scale and grade of high-temperature geothermal resources in the "Xizang - Sichuan - Yunnan" area are investigated in detail to accelerate the promotion of Yunnan Zangchuan geothermal power generation and support China's high-temperature geothermal power generation. In China, the medium and low temperature geothermal resources are the main, supplemented by high temperature geothermal resources, and the current development and utilization of medium and low temperature geothermal resources is far from enough. It is necessary to intensify geothermal exploration and development in tectonic zones and sedimentary basins, effectively utilize abandoned mines, oil and gas Wells, and shallow geothermal energy, and form a new industrial development model of "deep and shallow combination, heating + cooling + power generation + other".

Improve the geothermal industry support framework and improve the economy of geothermal projects. Establishing a risk mitigation program for upfront investment at the national level will help developers reduce subsurface risks in geothermal geological exploration. In addition, harmonizing and simplifying the licensing process for geothermal energy projects will promote the efficient development of projects, and introduce relevant policies to promote the development of the geothermal industry according to the characteristics of geothermal utilization. In terms of economy, on the one hand, the low-carbon heating and cooling technology for new large commercial buildings is subject to rigid policy constraints, and on the other hand, heating and cooling projects are supported to establish a pricing system based on market supply and demand. In terms of technical specifications for geothermal heating and cooling, the integration of geothermal heating and cooling should be advocated to improve the economy of geothermal projects by extending the cycle. Drawing on the initial development subsidy policy of Fengguang project, the geothermal power generation project shall be supported in terms of land use, financing, subsidies and on-grid electricity price, so as to promote the commercial development of geothermal power generation projects.

We will promote technological innovation and research and development to support large-scale geothermal development and utilization. Keeping up with the pace of geothermal power generation technology research and development in developed countries, China needs to carry out forward-looking scientific and technological research on a series of bottleneck technologies such as high-temperature geothermal resource exploration, dry hot rock power generation, ultra-high temperature critical drilling engineering, geothermal power generation, and explore the technical feasibility of closed-loop geothermal system development and utilization in China. Strengthen the scientific and technological research and development of shallow geothermal energy development and utilization, carry out shallow geothermal energy technology research in the aspects of operation and strategy optimization of compound ground source heat pump system, and improve the efficiency of heat pump localization, establish a shallow geothermal energy development evaluation index system, and guide the government and investors to develop and utilize shallow geothermal energy according to local conditions. Build a typical dry hot rock demonstration test project, provide policy support for related technical research, prove the feasibility of the project technology, and enhance the confidence of decision makers and other stakeholders. We will continue to develop technologies and materials for geothermal resource evaluation, high-efficiency drilling, and high-efficiency buried pipelines to improve the efficiency of geothermal energy development and utilization. Improve the technical level of mineral extraction from geothermal brine, explore the feasibility of geothermal hydrogen production, and expand the application of geothermal energy.
