| Summary: | Membrane-based CO<sub>2</sub> capture has emerged as a promising technology for industrial decarbonization, offering advantages in energy efficiency, modularity, and environmental performance. This review presents a comprehensive assessment of membrane processes applied across major emission-intensive sectors, including power generation, cement, steelmaking, and biogas upgrading. Drawing from pilot-scale demonstrations and simulation-based studies, we evaluate how flue gas characteristics, such as CO<sub>2</sub> concentration, pressure, temperature, and impurity composition, govern membrane selection, process design, and operational feasibility. Case studies highlight the technical viability of membrane systems under a wide range of industrial conditions, from low-CO<sub>2</sub> NGCC flue gas to high-pressure syngas and CO<sub>2</sub>-rich cement emissions. Despite these advances, this review discusses the key remaining challenges for the commercialization of membrane-based CO<sub>2</sub> capture and includes perspectives on process design and techno-economic evaluation. The insights compiled in this review are intended to support the design of application-specific membrane systems and guide future efforts toward scalable and economically viable CO<sub>2</sub> capture across industrial sectors. |
