Direct air capture (DAC) has emerged as an essential, emissions source independent pathway toward global net-zero targets. Compared to solvent-based systems, solid adsorbent-based DAC holds distinct advantages due to its broader material versatility, modular scalability, and streamlined equipment architecture. However, transitioning from laboratory-scale material discovery to commercial deployment requires a holistic, system-level engineering approach. Because intrinsic adsorbent properties dictate the design of scalable structured contactors, the selection of energy-efficient regeneration methods, and the ultimate techno-economic and environmental viability of the process, these interdependent components must be synergistically co-optimized. To address this co-optimization challenge, the authors provide a critical, integrated evaluation of solid adsorbent DAC.
