浙江省固定源CO2排放量空间分布与源汇匹配特征
Spatial distribution and source-sink matching of stationary CO2 emissions in Zhejiang Province
摘要
Abstract
[Objective]Carbon capture,utilization,and storage(CCUS)is supposed to become an essential technology for the consumption of fossil fuels under the background of achieving carbon neutrality.Delving into the spatial distribu-tion of regional CO2 stationary sources and the source-sink matching characteristics will contribute to more rational de-cision-making in CCUS deployment and promote the development of carbon sequestration technology.[Methods]This study investigated the spatial distribution of CO2 stationary sources in Zhejiang Province and,using the carbon emission factor method,assessed their CO2 emissions based on their scales.Furthermore,it analyzed the geological features of both onshore and offshore basins in the province and evaluated the conditions and potential for CO2 sequestration of pos-sible target basins.The cluster division of CO2 stationary sources in the province was conducted through cluster analysis.Using the minimal transportation cost as the objective function,the optimal source-sink matching was explored under the assumption that coastal transfer hubs were available for onshore-offshore CO2 pipeline transportation.[Results and Conclusions]There existed 198 CO2 stationary sources in Zhejiang Province in 2024,including thermal power plants,steel mills,cement plants,and synthetic ammonia plants,with total annual CO2 emissions of approximately 297 39.73×104 t.Among these,thermal power plants released 82.96%of CO2 emissions.These sources included 21 CO2 stationary sources with annual emissions exceeding 500×104 t,accounting for 63.87%of the total annual emissions,and 157 sources with annual emissions exceeding 10×104 t,totaling about 29 512.52×104 t per year.In Zhejiang Province,on-shore basins are characterized by limited areas and poor conditions for CO2 sequestration.In contrast,the offshore East China Sea Shelf Basin exhibits favorable sequestration conditions,a high degree of hydrocarbon exploration,and consid-erable potential for CO2 sequestration,capable of storing the CO2 emissions of 196 years in the province.In this off-shore basin,the Yangtze,Qiantang,and Oujiang sags,located near coasts,can collectively offer a sequestration capacity of the CO2 emissions of 54 years in the province.The matched CO2 sources and sinks show a parallel distribution over-all.Under varying distance thresholds for the cluster division of CO2 sources,shifts in cluster centers or the proximity of CO2 sources to multiple carbon sinks might cause a CO2 source to match different carbon sinks.The results of this study will provide a theoretical basis for scientific decision-making and rational planning of CCUS in Zhejiang Province in the future,thereby contributing to the low-carbon utilization of fossil fuels and the achievement of carbon neutrality in the province.关键词
