"双碳"目标下河北省农村取暖的低碳转型实施路径研究OA

Under the goal of emission peak and carbon neutrality,rural heating is facing a low-carbon transformation.On the basis of analyzing the current situation of rural heating in Hebei Province,this paper summarizes the demand for low-carbon heating in rural areas under the goal of emission peak and carbon neutrality.Taking rural residential in Zhangjiakou,Tangshan,and Shijiazhuang areas of Hebei Province as examples,compares and analyzes the heat demand,energy consumption,pollutant emissions,heating costs,and initial investment of six heating methods during the heating season,including traditional coal heating,natural gas heating,biomass formed fuel heating,electric direct heating,air-source heat pump heating,and"PV + air-source heat pump"heating.It also explores the low-carbon transformation implementation path suitable for rural heating in Hebei Province.The research results show that:1)Among different heating methods,"PV + air-source heat pump"heating has the best comprehensive performance in terms of cleanliness,low-carbon,and sustainability,but its initial investment is relatively high.It can be promoted in the form of"government subsidies + bank loans".2)With the basic completion of clean heating renovation in rural areas of Hebei Province,the specific implementation path for low-carbon transformation of heating is as follows:in the area where gas replacing coal and electricity replacing coal are not covered,priority should be given to promoting the use of"PV + air-source heat pump"heating for buildings with a remaining service life of 20 years or more.For old buildings,promote the use of air-source heat pump heating or biomass formed fuel heating.In the area where electricity replacing coal,roof distributed PV power generation can be developed to solve the problems of high heating costs and high carbon footprint of the heating method of electricity replacing coal.In the area where gas replacing coal,the original gas transmission and distribution pipeline will still be retained to deliver gas to users for cooking,and then combined with local economic and social characteristics,and resource endowments,green and low-carbon technologies and energy-saving equipment will be promoted and applied.At present,the application of roof distributed PV power generation can be promoted first,and then the use of air-source heat pumps for heating can be gradually promoted.Then,the collaborative application of natural gas heating and"PV + air-source heat pump"heating gradually moves towards a single heating method using"PV + air-source heat pump".
