High-Flux Direct Air Capture Contactor

A novel high flux direct air capture (HiDAC) contactor is developed by using materials to increase the effective surface area for CO2-solvent contact. The HiDAC contactor was used to demonstrate ~2 times higher CO2 capture efficiency (i.e., ~60%) compared to that of a reference packing (i.e., ~30%, Brentwood structured packing). As a potential breakthrough strategy, the highly efficient CO2-capture HiDAC contactor can be employed to significantly reduce capital cost using a compact system.
