CO2 reduction

Pre-pilot-scale tandem CO2 electrolysis

Electroreduction of CO2 in coupled tandem electrolyzers is an enabling technology that can produce valuable chemicals, utilizing different reaction environments in each cell. Now, a kilowatt-scale tandem CO2 electrolysis stack has demonstrated that the selective conversion of CO2 to acetate can achieve competitive prices.
