The sub-center of the city is geothermal transported, and the Beijing heat pipe network is transmitted
Adjust the energy structure and increase the source of heat supply. Recently, Beijing issued the "Implementation Opinions on Comprehensively Promoting the High-quality Development of New Energy Heating", supporting the application of various new energy heating technologies in public buildings, residential buildings, industrial parks, agriculture and rural areas, and encouraging the expansion of the application of new energy heating technologies in new infrastructure and other scenarios. By 2025, we will strive to account for 10% of the city's heating area with new energy heating area.
Beijing's new energy heating will reduce carbon emissions by 1.7 million tons per year
In the upcoming heating season, the geothermal heating project of the 01 block of the 07 group of the sub-center of Beijing is expected to be completed and put into use, and the medium and deep geothermal heat from the sub-center of the city will be transported to the thermal pipe network of Beijing.
"As a pilot demonstration project of medium and deep geothermal heating, plots D and F will have a heating area of more than 350,000 square meters, which can reduce 7,650 tons of carbon dioxide emissions and save 1.98 million standard cubic meters of natural gas every year after completion. The person in charge said.
Beijing is one of the few capitals with geothermal resources, with abundant reserves of new energy heating resources. In recent years, Beijing's new energy heating has entered a period of rapid development, with continuous enrichment of application forms, gradual improvement of management mechanisms, and steady improvement of heating scale, and a number of demonstration projects such as ground source heat pump heating (cooling) project of Beijing Daxing International Airport, ground source heat pump heating (refrigeration) project of administrative office area of Beijing city sub-center, and ground source heat pump heating (refrigeration) of three major buildings of Beijing city sub-center have been built. It is worth mentioning that the first successful construction of the medium and deep geothermal (underground heat exchange) heat pump heating system test well in Beijing is in the sub-center of Beijing, which can provide winter heating for about 1.89 million square meters of buildings in the comprehensive transportation hub of the sub-center station, and can reduce the consumption of 8,000 tons of standard coal per year compared with the traditional coal-fired heating method.
According to statistics, by the end of 2022, the city's new energy heating area has reached 106 million square meters, which can replace about 800 million cubic meters of gas every year and reduce carbon dioxide emissions by 1.7 million tons. Based on the average carbon emission of 3 tons of private cars in Beijing with an annual mileage of 11,000 kilometers, this figure can offset the carbon emissions of more than 560,000 private cars in a year, and the effect of energy saving and emission reduction is remarkable.
The low-carbon transformation of the "stock" of heat demand and the "incremental" low-carbon heat supply will help to further adjust the energy structure. To this end, the Beijing Municipal Development and Reform Commission, the Municipal Planning and Natural Resources Commission and other ten departments have studied and formulated the "Implementation Opinions on Comprehensively Promoting the High-quality Development of New Energy Heating", promoting the high-quality development of new energy heating in Beijing, and accelerating the construction of a green, low-carbon, multi-energy coupling, interconnected, intelligent and efficient heating system based on energy resource endowment.
Encourage the application of new energy heating technology in multiple scenarios
The implementation opinions clearly put forward that the city encourages the use of shallow ground source heat pumps, reclaimed water (sewage) source heat pumps, medium and deep geothermal, biomass heating, urban and industrial waste heat utilization and other new energy heating technologies, and supports the application of various new energy heating technologies in public buildings, residential buildings, industrial parks, agriculture and rural areas. At the same time, we will encourage the expansion of the application of new energy heating technologies in new infrastructure and new infrastructure scenarios, and support the pilot application of new technologies such as carbon dioxide ice making and hydrogen energy cogeneration.
The reporter noted that the implementation opinions also clarified the appropriate forms of new energy heating technology for different building types in public buildings, residential buildings, industrial parks, and rural areas. For example, public buildings are suitable for technologies such as shallow ground source heat pumps and reclaimed water source heat pumps, and residential buildings are suitable for medium and deep geothermal heat, green electricity heat storage, biomass heating and other technologies.
The implementation opinions are aimed at reclaimed water (sewage) source heat pump heating projects, medium and deep hydrothermal geothermal heating projects, Medium and deep underground heat exchange geothermal heating projects and other types of new energy heating projects, put forward clear management requirements; strengthen the effective connection between the development goals of new energy heating and planning at all levels, and promote the proportion of new energy heating applications into the land space planning and comprehensive implementation plan of land plots and other planning documents; it is also proposed to optimize the project approval process, innovate the development and utilization mode, guide and support social capital to actively participate in the construction of new energy heating projects, and stimulate the vitality of the new energy heating market.
Invest in and support technological innovation in new energy heating projects
Technological innovation is a major starting point to promote the upgrading of the city's heating system. The implementation opinions encourage the in-depth integration of industry, university and research, support the construction of an innovation consortium led by enterprises, supported by universities and scientific research institutes, and coordinated by various innovation subjects, and jointly carry out research and development of key equipment;
"In accordance with the installed capacity of new energy heating, the application of new energy heating technologies, the construction of multi-energy coupled integrated energy stations and other different forms, the qualified new energy heating projects will be given certain fixed asset investment support of the municipal government, so as to further reduce the investment cost of enterprises and meet the new requirements of large-scale development and high-quality application of new energy heating. The relevant person in charge of the Municipal Development and Reform Commission said.
For new energy heating projects supported by the municipal government's fixed asset investment, Beijing will encourage professional institutions with corresponding credit to manage the whole process of project construction, and improve the technical standards and safety standards in the city's new energy heating related fields such as geothermal energy, reclaimed water (sewage) resources, biomass energy, air energy and new comprehensive energy infrastructure.
Strive to account for 10% of the new energy heating area by 2025
The implementation opinions encourage the expansion of the application of new energy heating technology in new infrastructure, new infrastructure and other scenarios. Anchored to the goal of building a thousand-year-old city, Beijing's urban sub-center maintains an annual investment scale of more than 100 billion yuan, and the new infrastructure scene is abundant. The reporter learned that the sub-center of the city is gradually changing the current heating pattern, striving to establish a safe and efficient green energy demonstration, and orderly promoting the integration of regional scattered heat sources and the replacement of heat pumps. By the end of the 14th Five-Year Plan, 80% of the usable area of new buildings will be equipped with photovoltaic solar thermal equipment, and the geothermal heating area will reach 12.8 million square meters.
"Vigorously developing new energy heating is an important starting point for achieving the goal of carbon peaking, and with the implementation of the "Implementation Opinions", it will further promote the progress of new energy heating technology and market improvement, and the capacity and scale of new energy heating are also expected to be further improved. The relevant person in charge of the Municipal Development and Reform Commission said. According to the implementation opinions, by 2025, Beijing will strive to account for 10% of the city's heating area with new energy heating, and by 2030, it will strive to account for 15% of the city's heating area, which can reduce carbon emissions by about 3.3 million tons.
