Amine solutions for CO2-capture: how to get from PCC to DAC?

Year: 2026

Type: review

Abstract: The use of amine solutions for direct air capture (DAC) can draw on the extensive experience from post-combustion CO 2 -capture (PCC) applications. The low CO 2 concentration in air, however, results in the need for significantly altered process designs, different equipment and new liquid absorbents, while retaining the overall process essentials of the thermal swing-driven CO 2 -capture process. Here, we explore several DAC process design considerations and formulate key DAC process attributes, using publicly available results from DAC process modelling.
