• An operational advantage that enables the deployment of technologies for the valorization of CO 2 can be achieved through the integration of the capture and conversion technologies. In that perspective, switchable polarity solvents (SPS) were assessed as re-usable capture-electrolyte media for the electrochemical production of syngas at low temperatures and pressures. A polymer electrolyte membrane cell was used to liberate captured CO 2 gas in proximity to the cathode without the addition of CO 2 gas. Due to the proximate location of release, the produced syngas had minimal CO 2 dilution with H 2  : CO ratios between 2 to 4. For the first time captured CO 2 has been reduced to CO with conversions and yields over 70% and at current densities over 100 mA cm −2 . Switchable polarity solvents allowed for the first time the electrochemical reduction of captured CO 2 for an efficient production of syngas.
