Boosting the Single-Pass Conversion for Renewable Chemical Electrosynthesis

Efficient engineering design of CO ₂ and CO electrolysis systems is key to achieving practical renewable energy conversion and storage via the upgrading of CO ₂ . 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.
