The application of membranes in the DAC process (m-DAC) is still in its infancy, owing to the low CO₂ concentration (400 ppm) in air. However, simulations and laboratory studies have demonstrated the feasibility of m-DAC. With the development of high-performance membrane materials and the design of multistage membrane processes, the implementation of m-DAC will be a promising strategy for the efficient reduction of CO₂ concentration in air. This review presents current studies on the m-DAC process and recently developed membranes for CO₂/N₂ separation which could be potentially used in that process, as well as highlighting research gaps that currently represent obstacles to the wider use of membranes for m-DAC.
