Comprehensive review of experimental studies, numerical modeling, leakage risk assessment, monitoring, and control in geological storage of carbon dioxide: Implications for effective CO2 deployment strategies

Abstract

The geological storage of carbon dioxide (CO₂) represents a promising strategy for mitigating climate change by securely sequestering CO₂ emissions. This review article aims to provide a comprehensive overview of the current state of research and development in the field of geological carbon dioxide (CO₂) sequestration. We systematically examined a wide range of recent literature, focusing on advancements in numerical simulations, experimental studies, risk assessments, and monitoring techniques related to CO₂ sequestration. Literature was selected based on relevance, recency, and contribution to the understanding of key challenges and solutions in CO₂ storage, with sources spanning peer-reviewed journals, conference proceedings, and significant technical reports. Our review highlights several key themes: the integration of machine learning and advanced numerical models in predicting CO₂ behavior in subsurface formations; innovative experimental approaches to understanding the physicochemical interactions between CO₂, brine, and geological substrates; and the development of robust risk assessment frameworks to address potential leakage and induced seismicity. We also explore recent advancements in monitoring technologies, emphasizing their critical role in ensuring the long-term integrity and effectiveness of CO₂ storage sites. Overall, this review synthesizes the latest findings and identifies gaps in current knowledge, providing a roadmap for future research directions. Our aim is to enhance the understanding of CO₂ sequestration processes, support the development of safer and more efficient storage methods, and contribute to the global effort in mitigating climate change through effective carbon management strategies. © 2024 Society of Chemical Industry and John Wiley & Sons, Ltd.
