Direct air capture (DAC) of CO₂ has emerged as a complementary mitigation strategy. However, current DAC technologies are limited by the high energy requirements inherent to the thermal release of captured CO₂, which are caused by the low thermodynamic efficiency of heat-driven processes, as constrained by Carnot principles. Redox-mediated electrochemical carbon capture (RMECC) offers a promising pathway to overcome these limitations. RMECC with DAC application remains in an early developmental stage and requires further optimization to enable energy-efficient, cost-effective, and scalable deployment. In this perspective the design of sorbents, electrolytes, and electrochemical cell configurations in the field of RMECC are discussed with an emphasis on sustainable approaches for the demands of DAC applications.
