Abstract Liquid‐based CO 2 direct air capture (DAC) is a pivotal technology for mitigating climate change. Energy‐intensive desorption, high regeneration temperatures, and solvent degradation are key challenges. Here, low‐temperature catalytic membrane vacuum (C‐MVR) as promising approach sustainable energy‐efficient DAC developed evaluated. Noncatalytic experiments conducted using three commercial modules four green amino acid salts under varying conditions (e.g., temperatures flowrates). Based on transfer rates, ultra‐thin dense composite membranes aqueous potassium taurinate (TauK) the most MVR in applications. For C‐MVR trials, ion‐exchange resin improves desorption fluxes by up to 64.4% reduces thermal energy requirements 39.1%. TauK demonstrates highest flux lowest consumption. Parametric analysis of catalyst performance amount, concentrations also performed. To minimize any potential precipitation TauK, carbonate (K 3 ) added, showing minimal impact kinetics improvement. The findings this study highlight practical applicability boost rate reduce input.
