随着全球气候变化问题的加剧,减少二氧化碳排放、实现低碳经济转型已成为各国应对气候危机的共同目标。二氧化碳捕集利用与封存(CCUS)作为目前实现化石能源低碳化利用的唯一技术选择,被视为实现碳减排的重要路径之一。然而,CCUS大规模部署面临诸多挑战,其中跨区域碳运输成本高、捕集源与封存汇的空间匹配不平衡是关键难题。为此,此次研究通过建立源汇匹配模型,结合Delaunay三角剖分算法构建候选管道网络,并通过管道共享策略优化运输路径,力求在多情景捕集规模下,构建出兼顾经济性与可操作性的全国性CCUS部署方案。研究结果显示,在各捕集规模情景下,CCUS部署的重点逐渐由中东部的经济和工业发达省份向资源丰富的内蒙古、新疆等地区转移,在全国范围内形成多个集群。分阶段的区域布局策略为政府提供了差异化的政策支持路径,有助于在全国范围内逐步推广CCUS改造。该研究为未来大规模的CCUS部署提供了科学依据和技术路径,揭示了通过合理的网络构建与共享机制,可以实现较低成本的碳捕集与运输。同时,该方法可为实现全国碳达峰和碳中和目标提供长期的支持。

As global climate change intensifies,reducing carbon dioxide emissions and achieving a low-carbon economic transition have become common goals for countries in addressing the climate crisis. Carbon Capture,Utilization and Storage(CCUS),as the only current technological option for low-carbon utilization of fossil energy,is seen as a critical pathway for carbon reduction. However,the large-scale deployment of CCUS faces numerous challenges,with high inter-regional carbon transport costs and spatial mismatches between capture sources and storage sinks being key issues. To address these challenges,this study establishes a source-sink matching model and uses the Delaunay triangulation algorithm to construct a candidate pipeline network. A pipeline-sharing strategy is also employed to optimize transport routes,aiming to develop a national CCUS deployment plan that balances economic efficiency and operational feasibility across multiple capture scale scenarios. The results indicate that under various capture scale scenarios,the focus of CCUS deployment gradually shifts from the economically and industrially developed provinces in central and eastern China to resource-rich regions such as Inner Mongolia and Xinjiang,forming multiple clusters nationwide. This phased regional layout provides differentiated policy support pathways for the government,facilitating the gradual national rollout of CCUS retrofitting. The study provides a scientific basis and technical roadmap for large-scale CCUS deployment in the future,revealing that reasonable network construction and sharing mechanisms can achieve low-cost carbon capture and transport. Additionally,this approach offers long-term support for China's national goals of achieving carbon peaking and carbon neutrality.
