Title: General Techno-Economic Analysis of CO2 Electrolysis Systems

Journal Article · · Industrial and Engineering Chemistry Research

The electrochemical reduction of carbon dioxide (CO2) has received significant attention in academic research, although the techno-economic prospects of the technology for the large-scale production of chemicals are unclear. In this work, we briefly reviewed the current state-of-the-art CO2 reduction figures of merit, and performed an economic analysis of a generalized CO2 electrolyzer system for the production of 100 tons/day of various CO2 reduction products. While carbon monoxide and formic acid were the most economically favorable products under current conditions, higher-order alcohols such as ethanol and n-propanol could be highly promising if reasonable electrocatalytic performance benchmarks were achieved. Furthermore, we established performance targets such that if these targets are achieved, electrochemical CO2 reduction for fuels and chemicals production can become a profitable option as part of the growing renewable energy infrastructure.
