Abstract
Electrochemical CO2 reduction aims to compete with Power-to-X alternatives but is well behind the scales of water electrolyzers and thermochemical reactors. In a recent issue of Nature Chemical Engineering, Crandall and co-workers demonstrate a 1000 cm2 tandem CO2/CO electrolyzer for acetate production. The work invites discussion on scientific and engineering scale-up challenges.
