(A) CO total production cost (TPC) plotted as functions of current density and faradaic efficiency for determining profitability by assuming plant lifetime of 20 years and electrolyzer cost of 10,849 $/m2. (B) CO TPC plotted as a function of CO2 concentration, assuming single-pass conversion, current density of 300 mA/cm2, and faradaic efficiency of 99%. Reproduced from ref (220). Copyright 2021 ACS.
