Carbon dioxide emissions to the atmosphere are major drivers for climate change. In this project, different promoters including carbonic anhydrase, amino acids and a carbonic anhydrase inspired polymer were examined in potassium carbonate solvents for enhancing the carbon dioxide absorption kinetics. Results indicate that the addition of effective promoters can significantly increase the carbon dioxide absorption rate by more than ten times and this can reduce the capital costs and operation costs of a carbon capture plant.
