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



First, scientific overall planning of renewable energy heating work

Renewable energy heating as an important part of regional energy planning, in the renewable energy development goals should be clear heating development goals, according to the local resource endowment and energy demand to promote renewable energy heating technology, reasonable layout of renewable energy heating projects. Do a good job of connecting renewable energy heating with other heating methods, and support the construction of complementary heating systems that combine renewable energy and other heating methods. In the planning and construction process of urban renewal, new urban areas, and industrial parks (districts), do a good job of connecting renewable energy heating and urban development planning, and promote the integration of renewable energy and conventional energy heating systems. Focus on the planning, design and transformation of urban heating systems and thermal pipe networks, and optimize the design of heating pipe networks according to the characteristics of renewable energy. In the process of implementing the rural revitalization strategy, do a good job in the connection of renewable energy heating and rural revitalization strategic planning, and take renewable energy as one of the important ways to meet the needs of rural heating.

Second, promote all kinds of renewable energy heating technology according to local conditions

1. Actively promoting the development and utilization of geothermal energy. Focus on the promotion of medium and deep geothermal energy heating, in accordance with the principles of "fixed mining by irrigation, balanced mining and irrigation, and balanced water and heat", according to the formation mechanism of geothermal energy, the grade and amount of geothermal resources, and the ecological environment conditions of groundwater, the implementation of total control, zoning and classified management, and the combination of centralized and decentralized ways to promote medium and deep geothermal energy heating. The popularization and application of "underground heat transfer" technology should be intensified in areas with suitable conditions. Actively develop shallow geothermal energy heating, economically and efficiently replace loose coal heating, and develop surface water source, soil source, underground water source heating and cooling in areas where conditions exist. Encourage the use of oilfield produced water to develop geothermal energy heating, groundwater resources and the comprehensive utilization of mineral resources. Within the groundwater drinking water source and its protected area, it is prohibited to use the protected target aquifer as the source of heat pump water. It is prohibited to use groundwater as a source of heat pump water in areas where groundwater mining is prohibited, deep (confined) aquifers, and areas or corresponding aquifers where geothermal water cannot be effectively recharge. Groundwater recharge shall not cause groundwater pollution.

(2) Rationally develop biomass heating. We will develop biomass cogeneration in an orderly manner, accelerate the transformation and upgrading of biomass power generation to cogeneration in light of local conditions, and provide domestic heating for counties with resource conditions and rural areas with concentrated population, as well as central heating for small and medium-sized industrial parks. We will rationally develop biomass heating fueled by agricultural and forestry biomass, biomass molding fuel, and biological natural gas, and encourage the use of large and medium-sized boilers for regional central heating in rural, urban and other populated areas. Biomass boilers shall not be mixed with coal, garbage, industrial solid waste and other materials, supporting the construction of efficient pollution control facilities such as cloth bag dust removal, to ensure emissions standards, and encourage ultra-low emissions. In rural areas where air pollution prevention is not a key area, household biomass heating can be promoted according to local conditions in accordance with the principle of local materials.

(3) Continue to promote solar and wind power heating. Encourage large and medium-sized urban civil buildings with heating needs to give priority to the use of solar heating systems; Encourage the use of solar heating systems in small towns and rural areas; Make full use of solar heating in industries with large heat demand and matching solar energy characteristics such as agricultural greenhouses and aquaculture; In areas where the central heating network is not covered and there is demand for dual supply of cold and hot, the solar water, heating and cooling triple supply system is used on a pilot basis. Encourage the use of complementary heating systems that combine solar heating with other heating methods. Build a wind power heating cooperation mechanism involving the government, power grid enterprises, power generation enterprises and users, and realize clean wind power heating through the joint scheduling and operation of heat storage boilers at thermal stations and wind farms, so as to improve the overall operation efficiency and economy of wind power heating projects.

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.
