碳中和目标下中国碳捕集、利用与封存源汇匹配与集群布局研究
Source-sink matching and cluster layout of Carbon Capture,Utilization and Storage in China towards carbon neutrality
摘要
Abstract
Solving the problem of source-sink matching of Carbon Capture,Utilization and Storage(CCUS)can provide scientific support for the optimal layout of CCUS clusters.Based on the full consideration of transport distance,capture-transport-storage and utilization costs,a CCUS source-sink matching model was constructed with the carbon neutrality target as the emission reduction constraint and based on the principle of minimizing the cost of CCUS deployment.A comparative analysis was conducted on the optimal CCUS source-sink matching pathways and the economic costs of cluster layout options before and after considering the carbon utilization scenarios.The results show that achieving the carbon neutrality target requires the annual capture scale of CCUS to reach 513.33 Mt CO2.Compared with the scenario that only considers CO2 sequestration in saline aquifer,gas field and CO2-EOR,the number of carbon sources that need to be transformed by CCUS will increase from 332 to 434,the number of carbon sinks involved will increase from 49 to 276,and the length of the transport pipeline construction will increase from 21237.96 km to 31473.33 km,assuming the consideration of the mineralization of steel slag and the chemical conversion technology using CO2.The total abatement cost of deploying CCUS over the 30-year planning period would decrease from $760.4 billion to $514.1 billion,and the unit abatement cost would decrease from $49.38/t CO2 to $33.38/t CO2.The demonstration of carbon utilization technology can optimize the cluster layout options,play the cluster scale advantage,reduce the layout cost,and help form characteristic clusters.The Su-Lu cluster and Meng-Ning-Shaan-Jin-Ji cluster are the primary regions for CCUS deployment in the future,and the deployment of CCUS in the Bohai Bay and Northeast clusters is the most feasible.关键词
