Project Title: A Solvent/Membrane Hybrid Post-combustion CO₂ Capture Process for Existing Coal-Fired Power Plants

The University of Kentucky is developing a hybrid approach to capturing CO₂ from the exhaust gas of coal-fired power plants. In the first, CO₂ is removed as flue gas is passed through an aqueous ammonium-based solvent. In the second, carbon-rich solution from the CO₂ absorber is passed through a membrane that is designed to selectively transport the bound carbon, enhancing its concentration on the permeate side. The team’s approach would combine the best of both membrane- and solvent-based carbon capture technologies. Under the ARPA-E award, the team is enabling the membrane operation to be a drop-in solution.
