摘要
CCUS是实现碳中和目标的重要技术手段,目前中国正处于“双碳”目标的落实阶段,在CO_(2)地质封存的经济界限评价、源汇优化和安全监测方面还缺乏成熟的技术体系。从封存技术经济界限、源汇匹配技术、封存安全性及监测3个方面总结了中国CO_(2)地质封存技术发展历程。回顾了CCUS技术在捕集、运输、注入封存阶段的经济成本,进一步总结了目前各阶段的技术经济界限及其影响因素。此外,通过总结国内外CCUS源汇匹配技术发展现状,明确了中国源汇特征及其分布,提出了进一步开展源汇匹配优化技术的发展方向。最后,通过总结CO_(2)地质封存安全风险评价及封存监测技术,明确了经济高效、有效、定量的监测方法是未来的研究重点。
CCUS is an important technical means to achieve the carbon neutrality goal.At present,China is in the implementation stage of the“dual carbon”goal,and there is still a lack of mature technical system in the economic boundary assessment,sourcesink optimization and safety monitoring of geological sequestration of CO_(2).This paper summarizes the development process of China’s CO_(2) geological sequestration technique from three aspects,economic boundaries of sequestration technology,source-sink matching technology,and sequestration safety and monitoring,reviews the economic costs of CCUS technology in the capture,transportation,injection and burial period,and further summarizes the current technical and economic boundaries and influencing factors of each period.In addition,by summarizing the current development status of CCUS source-sink matching technology at home and abroad,the source-sink characteristics and distribution of China have been clarified,and further development directions for source sink matching optimization technology have been proposed.Finally,by summarizing the safety risk assessment and burial monitoring techniques for geological sequestration of CO_(2),it is clear that economically efficient,effective,and quantitative monitoring methods are the focus of future research.
