Abstract

The invention is directed to a method for electrochemically reducing carbon dioxide, and an apparatus for performing the method.The method of the invention comprisesa) contacting a carbon dioxide-containing gas stream with a capture solvent, thereby absorbing carbon dioxide from the carbon dioxide-containing gas stream to form a carbon dioxide-rich capture solvent;b) introducing at least part of the carbon dioxide-rich capture solvent into a cathode compartment of an electrochemical cell;c) applying an electrical potential between an anode and a cathode in the electrochemical cell sufficient for the cathode to reduce carbon dioxide into a reduced carbon dioxide product or product mixture in the carbon dioxide-rich capture solvent, thereby providing a carbon dioxide-poor capture solvent;d) collecting the reduced carbon dioxide product or product mixture, ande) optionally recirculating at least part of the carbon dioxide-poor capture solvent to an absorber unit,wherein the anode is separated from the cathode by a semi-permeable separator, and wherein the absolute pressure in the electrochemical cell is preferably 20 bar or more and 138 bar or less and the temperature in the electrochemical cell is preferably 0 °C or more.
