We will do a good job in heating with renewable energy according to local conditions

Third, continue to promote pilot demonstration work and the construction of major projects

Pilot demonstration work and major project construction will be carried out in areas where conditions are met, and experience in the operation and management of renewable energy heating projects will be explored. The construction and promotion of major geothermal heating projects can be implemented in areas with good geothermal resource endowments. We will encourage demonstration work on the centralized use of geothermal energy in medium and deep layers, demonstrate heating utilization models and application ranges of different geothermal resource grades, and explore new management technologies and market operation models conducive to the development and utilization of geothermal energy. It is appropriate to adopt the overall development of geothermal blocks to promote geothermal heating, and mobilize the enthusiasm of enterprises to protect resources and sustainable development. Encourage the county as a unit to promote the operation and management of biomass clean heating, a county by a project unit unified promotion, overall planning layout, improve the construction plan, strengthen project operations, coordinate resource collection and storage, improve terminal services, crack the problem of biomass heating small and scattered, standardize the management system, enhance economic competitiveness. Actively explore the decentralized rural biomass resource utilization and management model, encourage rural areas with dispersed housing, central heating and gas supply difficulties, and abundant biomass resources, take the county as a unit to consider the pilot construction of biomass processing stations, implement unified development, operation, service and management of local biomass resources, and effectively reduce the cost of biomass energy heating in rural areas. Improve the comprehensive utilization of rural biomass resources. We will encourage the development of local power grids and microgrids with clean energy as the main body, and support the use of wind power, photovoltaic, energy storage and microgrids for heating in northern China.

Fourth, do a good job of renewable energy heating support policy guarantee

Comprehensive consideration of renewable energy and conventional energy heating costs, residents' affordability and other factors, reasonable pricing of heating, explore the establishment of renewable energy heating investment and operation mode in line with market-oriented principles. Local governments are encouraged to actively support renewable energy heating projects such as geothermal energy heating and clean biomass heating. We will encourage priority construction of biomass cogeneration projects and strictly control projects that only generate electricity but not heat. Under the same conditions, biomass power generation subsidies give priority to support biomass cogeneration projects. Residential heating methods such as geothermal energy and household shaped fuel stoves are not subject to the restrictions of heating concessions. Support enterprises participating in geothermal exploration and evaluation to obtain geothermal resource franchise qualifications. Biomass molding fuel standards and biomass stoves product standards reflecting the characteristics of biomass and clean heating requirements have been introduced.

Fifth, strengthen research and development support for key technology and equipment

Support the reliable operation of high-temperature heat pumps, efficient underground heat transfer, the development and utilization technology of medium and deep geothermal energy "heat without water", the balance of medium and deep underground hot water production and irrigation, the analysis and environmental impact assessment of environmental geological problems that may be caused by geothermal water exploitation and cold water recharge, geothermal tail water recharge and water treatment, the safe use of biomass boilers, feeding systems and household stoves, and denitrification Research and development of key technologies and equipment such as solar energy seasonal heat storage and heating. Pay attention to the integration of renewable energy and conventional energy systems, research and development demonstration of integrated technologies, and improve the acceptance capacity of conventional energy systems for renewable energy.

Sixth, improve the renewable energy heating government management system

Clarify the division of responsibilities between the competent authorities and various departments of renewable energy heating work in various places to avoid the phenomenon of absence management, multiple management and repeated management. Strengthen the supervision of renewable energy heating work, establish and improve the supervision mechanism of the pre-project, approval and operation process, and ensure the standardized management of the industry. In terms of geothermal energy, an enterprise recharge credit system should be established to support the sustainable development and utilization of geothermal energy.
