Redox-active organic compounds that reversibly bind and release CO2 are promising candidates for carbon capture but are limited by the use of flammable, toxic aprotic electrolytes. Here the authors use salt-concentrated aqueous electrolytes in continuous CO2 separation with good performance metrics.
