Membrane gas separation is a promising next-generation technology for post-combustion CO2 capture that can significantly reduce energy consumption, instrument, and chemical footprint relative to mature amine scrubbing that is in widespread use. Nevertheless, despite many studies commercially viable membranes are not widely implemented at a large scale. This review presents a systematic overview of the current status and advances of membrane technologies for CO2 capture from post-combustion flue gas. In particular, the potential for recent developments in membranes for scale-up based upon required performance parameters in these settings will be reviewed. The challenges and barriers to the upscale of membrane technologies are discussed with respect to both materials and engineering perspectives. The technology readiness level of various technologies and remaining barriers to their implementation are provided.
