在含盐含水层中储存二氧化碳，是实现全球温室气体排放量每年大幅减少数十亿吨的现实手段。我们通过一系列实验室分析、实地研究和流程模拟，回顾了工业规模项目中涉及的过程。我们讨论的主要主题是(a)重要的物理化学过程，(b)限制二氧化碳储存能力的因素，以及(c)全球规模扩大的要求。虽然二氧化碳捕集与封存（CCS）技术可以被认为是成熟的和经过验证的，但它需要大规模和快速地扩大规模，以实现《巴黎气候协定》的目标。预计所需的二氧化碳注入井数量的增长明显低于历史上石油工业的钻井速度，这表明通过CCS进行脱碳是现代人类社会高度可信和负担得起的目标。为了降低部署成本并促进该技术的广泛采用，需要开发一些技术，这些技术应该集中在证明二氧化碳储存的长期保留和安全性，开发处理注入井和压力的智能方法，具有成本效益的监测解决方案，以及部署CCS中心与相关基础设施。预计《化学与生物分子工程年度评论》第12卷的最终在线出版日期为2021年6月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。
CO2 storage in saline aquifers offers a realistic means of achieving globally significant reductions in greenhouse gas emissions at the scale of billions of tonnes per year. We review insights into the processes involved using well-documented industrial-scale projects, supported by a range of laboratory analyses, field studies, and flow simulations. The main topics we address are (a) the significant physicochemical processes, (b) the factors limiting CO2 storage capacity, and (c) the requirements for global scale-up. Although CO2 capture and storage (CCS) technology can be considered mature and proven, it requires significant and rapid scale-up to meet the objectives of the Paris Climate Agreement. The projected growth in the number of CO2 injection wells required is significantly lower than the historic petroleum industry drill rates, indicating that decarbonization via CCS is a highly credible and affordable ambition for modern human society. Several technology developments are needed to reduce deployment costs and to stimulate widespread adoption of this technology, and these should focus on demonstration of long-term retention and safety of CO2 storage and development of smart ways of handling injection wells and pressure, cost-effective monitoring solutions, and deployment of CCS hubs with associated infrastructure. Expected final online publication date for the Annual Review of Chemical and Biomolecular Engineering, Volume 12 is June 2021.
