Electrochemical carbon dioxide reduction to multi-carbon products such as ethylene and ethanol is a promising method to store electricity in chemical bonds and produce bulk chemicals from CO₂. Simultaneous consideration of processes taking place at the molecular scale, electrolyser scale, and the process scale is crucial to efficiently move towards commercialization and avoid optimizing for unrealistic operating conditions. This chapter summarizes the relevant considerations at each vantage point and reviews the latest developments in CO₂ reduction toward multi-carbon products at different scales.
