        作为应对气候变化和实现碳中和必不可少的技术，碳捕集、利用与封存 （CCUS） 技术研发和应用受到全球主要国家高度重视。文章梳理近年来美国、欧盟、英国、日本等主要国家和地区CCUS发展战略，并采用文献计量、文本聚类等方法对全球CCUS科技研发态势进行分析。研究发现，这些主要国家和地区相继出台CCUS相关战略，将发展CCUS上升到国家战略高度，明确提出到2030年、2040年、2050年不同发展阶段的目标和重点攻关方向。CCUS技术领域的研究产出呈现快速增长趋势，研究主要集中在新一代低能耗与低成本CO₂捕集技术、安全可靠的地质利用与封存技术及CO₂高效转化利用制高价值化学品/燃料等方向。

        In the context of carbon neutrality, carbon capture, utilization, and storage (CCUS) technology has emerged as a critical focus for policymakers worldwide. Recognized as a critical tool for combating climate change and achieving carbon neutrality, CCUS has gained widespread endorsement from major nations and international organizations. Through methods such as bibliometrics, text clustering, and comprehensive research involving foreign official institutions and authoritative websites, this study delves into the technology strategy and development trends of CCUS. It is found that various countries，including the United States, Europe, and Japan, have sequentially rolled out CCUS strategies, elevating CCUS to a pivotal national strategic initiative. Moreover, they have delineated explicit objectives and emphasized research directives for diverse developmental phases leading up to 2030, 2040, and 2050. At present, the arena of CCUS technology is marked by swift expansion, with the relevant core technologies concentrating on low-energy and cost-effective CO₂ capture, dependable geological utilization and storage, and advanced CO₂ conversion processes aimed at yielding high-value chemicals and fuels.
