Electrochemically driven carbon dioxide capture is emerging as an energy-efficient alternative to thermally driven processes. Electrochemical systems can be operated under isothermal conditions, limiting energy loss via heat. A range of electrochemical carbon dioxide capture systems have been reported, including those based on electrochemically driven pH swings, capacitive systems, and systems that employ redox-active molecules such as quinones, both in protic and aprotic electrolytes. Using redox-active quinone molecules is one of the largest areas of research for new technologies due to their highly reversible redox-activity and stoichiometric capture of CO2 upon reduction.
