Abstract
- We introduce a gross-margin model to evaluate the technoeconomic feasibility of producing different C<subscript>1</subscript>-C<subscript>2</subscript> chemicals such as carbon monoxide, formic acid, methanol, methane, ethanol, and ethylene through the electroreduction of CO<subscript>2</subscript>. Key performance benchmarks including the maximum operating cell potential ( V<subscript>max</subscript>), minimum operating current density ( j<subscript>min</subscript>), Faradaic efficiency (FE), and catalyst durability ( t<subscript>catdur</subscript>) are derived. The V<subscript>max</subscript> values obtained for the different chemicals indicate that CO and HCOOH are the most economically viable products. Selectivity requirements suggest that the coproduction of an economically less feasible chemical (CH<subscript>3</subscript>OH, CH<subscript>4</subscript>, C<subscript>2</subscript>H<subscript>5</subscript>OH, C<subscript>2</subscript>H<subscript>4</subscript>) with a more feasible chemical (CO, HCOOH) can be a strategy to offset the V<subscript>max</subscript> requirements for individual products. Other performance requirements such as j<subscript>min</subscript> and t<subscript>catdur</subscript> are also derived, and the feasibility of alternative process designs and operating conditions are evaluated.
