Solar-Powered Direct Air Capture: Techno-Economic and Environmental Assessment.

ABSTRACT: Direct air capture (DAC) of CO₂ has gained attention as a sustainable carbon source. One of the most promising technologies currently available is liquid solvent DAC (L-DAC), but the significant fraction of fossil CO₂ in the output stream hinders its utilization in carbon-neutral fuels and chemicals. Fossil CO₂ is generated and captured during the combustion of fuels to calcine carbonates, which is difficult to decarbonize due to the high temperatures required. Solar thermal energy can provide green high-temperature heat, but it flourishes in arid regions where environmental conditions are typically unfavorable for L-DAC. This study proposes a solar-powered L-DAC approach and develops a model to assess the influence of the location and plant capacity on cap
