CCUS项目运行的经济性不足和激励政策体系不健全是限制煤电CCUS项目发展的重要瓶颈。运用ITEAM-CCUS模型评估CCUS项目运行的全流程经济特征，并以锦界电厂150 kt/a的CCUS示范项目为案例进行深度解析，识别单一激励政策需求强度和组合政策综合效果的差异化策略及其对CCUS项目运行的经济可行性。研究发现：(1) ITEAM-CCUS模型评估结果表明煤电CCUS项目具有较大的减排潜力，且在地区和企业层面上均具有良好的减排规模效应；(2)案例解析表明，CCUS项目在早期示范阶段，宜实行发电小时数补偿、上网电价补贴等确定性的激励政策，而在运行推广阶段，实行碳交易和绿色电力交易等市场化政策；(3)不同的政策组合对CCUS项目平准化捕集成本影响存在差异性，综合性政策体系对CCUS项目运行有极大的支撑作用。建议增加对CCUS项目运行的经济政策配套，并注重在不同阶段采取差异化的政策，以期推动煤电CCUS运行的经济可行性。
Abstract：The insufficient economic viability of CCUS project operations and the inadequate incentive policy system are significant bottlenecks hindering the development of coal-based CCUS projects. This study employs the ITEAM-CCUS model to evaluate the comprehensive economic characteristics of CCUS project operations and conducts an in-depth analysis using the Jinjie Power Plant 150 kt/a CCUS demonstration project as a case study. The research identifies differentiated strategies for the required intensity of single incentive policies and the comprehensive effects of policy combinations, as well as their impact on the economic feasibility of CCUS project operations. The findings reveal that:(1) the ITEAM-CCUS model assessment indicates that coal-based CCUS projects possess substantial emission reduction potential and demonstrate favorable economies of scale at both regional and enterprise levels;(2) the case analysis suggests that during the early demonstration phase of CCUS projects, deterministic incentive policies such as generation hour compensation and feed-in tariff subsidies should be implemented. In contrast, market-oriented policies like carbon trading and green power trading are more suitable for the operational promotion phase;(3) different policy combinations exhibit varying impacts on the levelized capture cost of CCUS projects, with a comprehensive policy system significantly supporting CCUS project operations.The study recommends enhancing economic policy support for CCUS project operations and adopting differentiated policies at various stages to improve the economic feasibility of coal-fired CCUS operations.
