Direct Air Capture (DAC) is a promising negative emission technology with the potential to remove excess CO₂ from the atmosphere. The levelized cost of solid sorbent (S-DAC) and liquid solvent DAC (L-DAC) is highly region-specific, driven by variability in weather conditions and renewable energy potential. This necessitates a holistic, global assessment that combines these two advanced technologies to identify cost-optimal technology-specific locations for DAC deployment. The authors identified optimal global locations for the S-DAC and L-DAC using an hourly cost optimization model that incorporates weather-driven performance and region-specific solar, wind, and geothermal energy resources under fully electric and hybrid energy configurations.
