中国碳捕集、利用与封存技术发展与展望

Development and Prospect of Carbon Capture,Utilization and Storage Technology in China

实现“双碳”目标是我国应对气候变化的重大决策,也是我国生态文明建设的重要内容。碳捕集、利用与封存(Carbon Capture,Utilization and Storage,CCUS)技术是实现“双碳”目标的关键性技术,也是我国达成二氧化碳零排放的保障性措施。本文简要介绍了CCUS主要环节的技术流程,概括了我国CCUS技术的发展历程。从技术水平、国家政策、示范项目情况等多个角度,总结了现阶段我国CCUS技术的整体研究与发展水平。并根据我国能源供给模式、工业发展水平等因素,分析并阐明了我国CCUS技术发展的必要性,以及现阶段CCUS技术发展所面临的挑战。最后本文还从行业角度出发,将CCUS技术与油气、建筑、农业、化工多种重点行业结合,提出了具体可行、互促互利的CO_(2)转化利用模式,为实现CCUS的商业化运行、保证CCUS技术的可持续发展提供了思路。

Achieve carbon peaking and carbon neutrality goals is the major policy decisions to respond to climate change, is also the important content of ecological civilization construction in China. Carbon capture, utilization and storage(CCUS) is a key technology to achieve carbon peaking and carbon neutrality goals, and also a guarantee measure to realize zero CO_(2) emission in China. This paper briefly introduces the technical process of the main links of CCUS, sums up the development process of CCUS in China, and gives a summary of the overall research and development level of CCUS technology in China at the present stage from the perspectives of technology level, national policy, and demonstration projects. In addition, according to China’s energy supply mode, industrial development level and other factors, this paper analyzes and expounds the necessity and challenges of developing CCUS technology in China. Moreover, this paper combines CCUS technology with key industries, such as oil and gas, construction, agriculture and chemical industry, and proposes a feasible and mutually beneficial CO_(2) conversion and utilization model. It provides ideas for realizing the commercial operation of CCUS and ensuring the sustainable development of CCUS technology.
