Carbon dioxide capture at its most basic form is the selective removal of CO2 from a mixture of gases. Current technology uses amines to react with CO2 to form carbamates. CO2 is then released by heating the carbamates to break the covalent bond with the nitrogen. The amine-based technology has high adsorption capacities and good selectivity for CO2 but there is a large energy demand to reverse the process meaning new technologies are needed. This led to recent interest in electrochemical carbon capture. Instead of relying on temperature swings to reverse the capture of CO2, and regenerate the sorbent, an electrochemical swing is applied by changing the potential difference in an electrochemical cell. This can range from using redox-active molecules such as quinones to reversibly bind to CO2 to electrochemically mediated pH swings using molecules such as phenazines or Neutral Red. As the process can be driven solely by renewable electricity, this can further decrease the environmental footprint of the operation of electrochemical carbon capture.
