University of Delaware researchers will develop a novel integrated electrolysis system to produce C2-C3 alcohols, such as ethanol and propanol, using carbon dioxide (CO2) from coal-fired power plant flue gas. The conversion technology will produce these valuable chemicals through a two-stage electrolysis process. In the first stage, flue gas will be pretreated to remove contaminants and will then be converted into carbon monoxide (CO) by CO2 electrolysis, followed by the second stage electrolysis process where the produced CO will be further converted into liquid C2-C3 alcohols with a high selectivity and energy efficiency. The objectives of this research are to show that the approach is feasible for the reduction of CO2 emissions, to design and evaluate two electrolyzer subsystems (i.e., CO2 and CO), and to establish economic and life-cycle models assessed by experimental data.
