摘要梳理了碳捕集、利用和封存（CCUS）技术各关键环节的发展概况，阐述了全球和我国现阶段CCUS技术应用进展和挑战.结果表明，在当前的经济技术水平下，CCUS项目难以实现成本效益的平衡，因此必须转变思路，将CO₂视为一种基础工业原料，加快CO₂资源化利用布局.基于此，提出CO₂转化利用金字塔模型，通过优化组合高附加值碳基材料、化工利用、生物合成等CO₂转化利用路径，形成兼具减排和商业价值的新型碳经济.最后，根据我国未来在能源领域的领先性和电网的灵活度的实际需要，提出了加快我国CCUS技术布局和应用的政策建议，以期助力CCUS技术产业化落地与可持续发展.

关键词 ：碳中和, 碳捕集、利用和封存, 碳经济, CO₂利用路径

Abstract：The development of various key links in carbon capture, utilization, and storage (CCUS) technology was reviewed, and the current progress and challenges of CCUS technology application globally and in China were analyzed. The results indicate that at the current economic and technological level, it is difficult for CCUS projects to achieve a cost-effective balance. Therefore, it is necessary to make changes and consider CO₂ as a basic industrial raw material to accelerate the layout of CO₂ resource utilization. Based on this, a pyramid model for CO₂ conversion and utilization was proposed, which optimized the combination of high-value-added carbon-based materials production, chemical utilization, biosynthesis, and other CO₂ conversion and utilization paths to form a new carbon economy balancing emissions reduction and commercial value. Finally, based on the practical needs of China's future leadership in the energy field and the flexibility of power grids, policy recommendations were proposed to accelerate the layout and application of CCUS technology in China, with the aim of assisting the industrialization and sustainable development of CCUS technology.
