我国目前是世界第一大碳排放国，煤炭占我国能源消费碳排放的75%以上，面临较大的减排压力。本文提出了碳捕获和埋存/碳捕获、利用和埋存（CCS/CCUS）技术发展方向，按时间节点制定了我国CO₂捕集技术和输送技术发展路线图、CO₂化工、微藻生物制油和矿化等利用技术发展路线图；对2020、2030、2050年可能达到的全国碳排放量进行测算，对节能降耗、调整能源结构、CCS/CCUS技术对CO2减排的贡献度进行了评估，并提出了推广应用建议。

China is currently the world's largest carbon emitter, and faces great pressure in emission reduction, with coal accounting for more than 75% of China's carbon emissions in energy consumption. In this paper, development directions of a carbon capture and storage (CCS) / carbon capture, utilization and storage (CCUS) technology in China are researched and proposed, roadmaps for CO₂ capture technologies and transportation technologies, CO₂ chemical industry, and micro-algae bio-oil production and mineralization technology are developed by time nodes, national carbon emissions that may be achieved by 2020, 2030, and 2050 are calculated, contributions of energy saving and consumption reduction, energy structure adjustment, the CCS/CCUS technology to CO₂ emission reduction are evaluated, and recommendations for popularization and application of the CCS/CCUS technology are proposed.
