规模化集群化部署是CCUS技术发展方向和化石能源低碳化利用的国家重大需求，CO2地质封存潜力与能源资源协同关系及机制是实现CCUS技术规模化、集群化部署的理论基础。系统梳理评述了国内外CO2地质封存潜力及其评价方法、CCUS源汇匹配与管网设计模型、CO2地质封存潜力与能源资源协同关系、CCUS集群部署技术基础与模式等领域的主要进展，讨论展望了我国CO2地质封存潜力与能源资源协同理论方法体系的研究思路。研究工作取得以下认识：CO2地质封存潜力制约着CCUS技术的发展潜力与应用规模，适宜性评价方法、封存容量评估方法和封存选址方法所构成的CO2地质封存潜力评价方法体系已初步建立，但亟待完善发展；源汇匹配是CO2运输管网设计与CCUS技术集群化部署的重要直接依据，完善建立CCUS源汇匹配规划优化模型与CCUS集群管网设计模型是技术关键，从单阶段静态规划模型向多阶段动态规划模型发展是方向；CO2地质封存潜力与能源资源协同关系构成了CCUS技术的约束条件，CCUS技术与可再生能源、氢能、储能等新能源技术的协同有望形成实现能源系统脱碳的新路径、新模式和新方向，CO2地质封存潜力与生物质、水资源协同关系约束了CCUS技术规模化部署地域和BECCS技术发展应用潜力，基于CCUS源汇匹配模型的能源资源系统优化模型研究也成为新的技术需求；CO2地质封存潜力、能源系统约束的CCUS源汇匹配优化方案和CCUS全流程技术体系构成CCUS集群化部署的重要技术基础，近源输送陆上封存CCUS集群部署模式应是我国优先考虑发展方向，远源输送陆上封存CCUS集群部署模式和离岸封存CCUS集群部署模式在我国长三角、大湾区等区域也有发展前景。

Large-scale cluster deployment is the development direction of the CCUS (Carbon Capture, Utilization and Storage) technology and the national major demand of fossil energy low-carbon utilization. The synergistic relationship and mechanism between CO2 geological storage potential and energy resources are the theoretical basis of the CCUS large-scale cluster deployment. In this study, the major progress in the fields of CO2 geological storage potential and its evaluation methods, the CCUS source-sink matching and pipe network design model, the synergistic relationship between CO2 geological storage potential and energy resources, and the technical basis and mode of the CCUS cluster deployment are systematically reviewed. The research ideas on the theoretical methodology of synergy between CO2 geological storage potential and energy resources in China are discussed and envisioned. The main conclusions of the research are as follows. The CO2 geological storage potential restricts the development potential and application scale of the CCUS technology. The evaluation method system of CO2 geological storage potential is preliminarily established, which is composed of suitability evaluation method, storage capacity evaluation method, and storage site selection method. However, the evaluation method system of CO2 geological storage potential urgently needs to be improved and developed in future research. Source-sink matching is the important direct basis for the CO2 transportation pipeline network design and the CCUS large-scale cluster deployment. The improvement and establishment of the optimization model between the CCUS source-sink matching and the CCUS cluster pipe network model is the key technology for the CCUS source-sink matching, and the transformation from single-stage static planning model to multi-stage dynamic planning model is the development direction. The synergy between CO2 geological storage potential and energy resources constitutes the constraint condition of the CCUS technology. The synergy between the CCUS technology and new energy technology, e.g., renewable energy, hydrogen energy, energy storage, etc. will be expected to form a new path, new mode, and new direction to achieve energy system decarbonization. The synergistic relationships between CO2 geological storage potential and biomass and water resources restrict the large-scale deployment area of the CCUS technology and the application potential of the BECCS (Bioenergy with Carbon Capture and Storage) technology. Therefore, the research on the optimization model of energy and resources system based on the CCUS source-sink matching model will be a new technical requirement. The CO2 geological storage potential, energy-system constrained CCUS source-sink matching optimization scheme, and full flowsheet CCUS technology constitute the key technical basis for the CCUS cluster deployment. The CCUS cluster deployment mode of onshore storage with near-source transportation should be the priority development direction in China. The CCUS cluster deployment mode of onshore storage and offshore storage with remote-source transmission also have development prospects in Yangtze River Delta and Great Bay Area.
