COAWAY use a unique process for removing CO2 from the air and propose using existing power plant cooling towers that already move large quantities of air to create the necessary throughput for the carbon capture process.

By surrounding the inlet of cooling towers with their CO2 absorption apparatus, large amounts of air can be processed quickly, driving down costs. Coaway captures the CO2 in a chemical reaction with an aqueous solution. The resulting material is ‘regenerated’ in a thermal process that also releases the captured CO2 as a concentrated stream ready for commercial use or sequestration.
