Boosting the Single-Pass Conversion for Renewable Chemical Electrosynthesis

Efficient engineering design of CO2 and CO electrolysis systems is key to achieving practical renewable energy conversion and storage via the upgrading of CO2. High selectivity, current density, and energy efficiency have been the focus of many research efforts. The single-pass conversion of the reactants is another crucial system parameter that has—until now—received too little attention. Recently in Joule, Ripatti et al. showcase an electrolyzer that achieves high single-pass conversion combined with high current density.
