"一带一路"沿线主要国家碳捕集、利用和封存潜力与前景研究

碳捕集、利用和封存（CCUS）技术是世界公认的最有前景的碳减排技术之一,它在不改变能源结构的前提下,实现碳的有效封存,是协调经济发展和环境可持续的双赢策略。为了探讨“一带一路”沿线主要国家CCUS技术的发展前景,文中基于CO₂封存机理和CO₂在油藏和气藏中理论封存量的评估方法,分析了“一带一路”沿线主要国家CO₂的封存潜力。结果表明,“一带一路”沿线主要国家有较高的CO₂封存潜力, 在油藏和气藏中的理论封存量达到6200亿t。虽然目前沿线大部分国家CCUS技术都处于起步阶段,但在政府投资和政策的支持下,CCUS技术将为“一带一路”沿线主要国家碳减排目标的实现做出重要贡献。

Potential and prospect of carbon capture,utilization and storage (CCUS) in the main Belt and Road Initiative countries

Carbon capture, utilization and storage (CCUS) is regarded as a very promising technology to reduce CO₂ emission worldwide. It is a win-win strategy to coordinate economic development and environment to achieve effective carbon storage without changing the energy structure. The potential and prospects of CCUS technology are analyzed in the main Belt and Road Initiative (BRI) countries in this paper, based on the mechanism of CO₂ storage in different formation, and a new evaluation method of CO₂ storage capacity. The result shows that the main BRI countries have great CO₂ storage potential of around 620 Gt. Currently, although CCUS technology is in the initial stage, with the support of government investment and policies, it will make a great contribution to the development of green and low-carbon economy in these countries.
