Carbonate Regeneration Using a Membrane Electrochemical Cell for Efficient CO Capture.

The use of atmospheric CO as a chemical feedstock is a promising way to decarbonize the chemical and transportation sectors, which currently rely heavily on fossil fuels. This transition demands new technologies to reduce the energy required to capture and separate CO. Here, we develop and demonstrate an alternative method of carbonate solution regeneration using an anion exchange membrane electrochemical cell.
