Although direct air capture (DAC) is a promising negative-emission technology, its widespread deployment remains hindered by high energy requirements and unfavorable economics. This paper presents a novel configuration integrating DAC with a chlor–alkali (CA) process referred to as the CADAC system. Key innovation involves directly supplying Ca(OH)₂ from the CA process to the DAC unit, eliminating the energy-intensive calciner–slaker loop required in conventional DAC configurations.
