METHOD OF ELECTROCHEMICALLY CONVERTING CARBON DIOXIDE INTO FORMATE SALTS

A method of producing formate salt from carbon dioxide; it includes receiving the carbon dioxide in a dry compartment, wherein the carbon dioxide diffuses from the dry compartment into a catholyte solution of a first wet compartment through the gas diffusion layer, and at least part of the carbon dioxide is transformed into formate by an electrochemical reaction, resulting in a formate-containing catholyte solution, whereby a carbonate byproduct is also produced from the carbon dioxide, remaining in the formate-containing catholyte solution; concentrating the formate in the formate-containing catholyte solution; separating the concentrated formate and the carbonate from the water of the formate-containing catholyte solution; and separating the carbonate from the formate to result in isolated formate salt.
