Abstract: Methods for enzyme-enhanced CO 2 capture include contacting a CO 2 -containing gas with an aqueous absorption solution at process conditions-such as high temperature, high pH, and/or using carbonate-based solutions-in the presence of Thermovibrio ammonificans carbonic anhydrase (TACA) or functional derivative thereof for catalyzing the hydration reaction of CO 2 into bicarbonate and hydrogen ions and/or catalyzing the desorption reaction to produce a CO 2 gas. The TACA may be provided to flow with the solution to cycle through a CO 2 capture system that includes an absorber and a stripper.
