Techno-economic evaluation and life-cycle evaluation of the electrochemical conversion course of with captured CO2 in amine-based solvent

Direct electrochemical conversion of captured CO2 expertise has obtained international consideration as an alternative choice to the present energy-demanding amine solvent regeneration and separation processes of typical carbon seize course of; nevertheless, the identification of the potential benefits of this course of from each the financial and environmental perspective will not be easy. Right here, we current course of designs of two commercial-scale carbon seize and utilization (CCU) processes: a direct electrochemical conversion course of by way of captured CO2 discount response (cCO2RR) in a monoethanolamine (MEA)-based media and an electrochemical conversion course of by way of CO2 discount response (CO2RR) in aqueous electrolyte media. On account of techno-economic evaluation, the levelized value of product CO (LCOC) of the cCO2RR course of is 6.1% decrease than that of the CO2RR course of, displaying good financial potential. Moreover, the life cycle evaluation revealed that when utilizing renewable electrical energy, the cCO2RR course of can have a way more optimistic environmental affect than CO2RR, even at present technological efficiency stage. We highlighted that the evaluation of the proposed cCO2RR expertise will develop into a very good guideline for the event of an built-in and new kind of CCU expertise with out being complacent with the present CCU expertise.
