Abstract: Greenhouse gas emissions are causing global mean temperatures to rise, and the most promising carbon capture, utilization, and storage (CCUS) and carbon capture and storage (CCS) technologies under the current system involve CO2 storage in clastic rocks. This review elucidates the mechanism of CO2 geo-storage (CGS) in clastic rocks, summarizes the storage conditions and methods, analyzes the storage potential assessment in detail, highlights the problems and risks, and discusses the future development directions. Although numerous studies have explored CO2 storage in depleted oil and gas reservoirs associated with clastic rocks and saline aquifers, systematic and comprehensive research remains scarce. This study offers the first comprehensive overview of all CO2 geological storage technologies related to clastic rocks and introduces a new and more robust set of storage potential assessment formulas based on previous studies. By analyzing the international theoretical and research results on clastic CGS, this study could enhance the understanding of the field and significantly contribute to achieving global carbon reduction targets.
