The Beijing Municipal People's Government issued the “Beijing New Energy System Plan for the Fifteenth Five-Year Plan Period”. Among them, it is pointed out that diversification and low-carbon upgrading of heat sources will be further promoted. Build a multi-energy complementary, green and low-carbon heating system. Strictly control fossil energy heating, encourage the integration and integration of existing boiler houses and improve quality and efficiency, implement thermoelectric decoupling and transformation of gas units in an orderly manner, speed up the layout of green electricity heat storage peak-shaving projects, carry out technical demonstrations on the feasibility of blending green hydrogen and flexible transformation, and promote the transformation of gas boilers from basic heat sources to peak shaving guarantee. Dig deep into waste heat resources and build multi-energy coupled integrated energy stations. Explore the use of deep geothermal resources from Tianjin and Hebei to replace gas boilers imported to Beijing for a long time. Promote the conversion of coal to clean energy according to local conditions, and insist that coal is not used under unnecessary conditions.
