Abstract

Various embodiments may include a method of electrochemical production of synthesis gas comprising: reducing carbon dioxide to a first product gas including carbon monoxide in a carbon dioxide electrolysis cell; splitting water to generate a second product gas including hydrogen in a water electrolysis cell; delivering at least one catholyte from the group consisting of: a first catholyte from the carbon dioxide electrolysis cell and a second catholyte from the water electrolysis cell, into a gas scrubbing apparatus; and removing non-reduced carbon dioxide from the first product gas in the gas scrubbing apparatus using the at least one catholyte as an absorbent.
