我国燃煤发电CCS/CCUS技术发展方向及发展路线图研究

Research on Technology Directions and Roadmap of CCS/CCUS for Coal-Fired Power Generation in China

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CO_2捕集技术和输送技术发展路线图、CO_2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CO_2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.
