Abstract

Carbon capture and storage (CCS) is widely regarded as a critical technology for achieving deep decarbonization and global net-zero emissions. However, despite its significant potential, large-scale deployment of CCS remains limited, primarily due to high economic costs that hinder commercialization. This paper provides a comprehensive review of the technological and economic challenges associated with post-combustion amine-based carbon capture, which is currently the most mature and widely applied capture approach. A systematic analysis of the cost distribution across the CCS value chain reveals that the capture stage contributes approximately 60–80% of the total lifecycle cost, mainly due to high capital and operational expenditures. The substantial energy demand for solvent regeneration is identified as a major factor contributing to the high cost of amine-based systems. The paper further compares various cost-reduction strategies, including process optimization, advanced solvent development (such as mixed amines, phase-change solvents, and ionic liquids), and emerging technologies including solid adsorption and membrane separation. The analysis indicates that conventional process improvements generally achieve limited cost reductions, whereas advanced solvent systems and alternative capture technologies offer greater potential for future cost optimization. Additional barriers, including limited economies of scale, underdeveloped industrial infrastructure, and the lack of standardized techno-economic assessment frameworks, are also discussed. Finally, the paper proposes future research directions to reduce CCS costs and promote its broader industrial application.
