Integrated CO2 capture and electrolysis: advancing industrial implementation

The electrochemical reduction reaction of CO 2 into valuable chemicals offers a promising route for carbon management and renewable energy storage. However, the economic feasibility of conventional CO 2 electrolysis is hindered by the energy-intensive provision of CO 2 . This mini review systematically explores the integrated CO 2 electrolysis approach, which directly couples the electrolyzer with CO 2 capture media, thereby passing costly intermediate stages. We concisely review the core aspects of this technology, including specialized cell designs, critical process parameters, and a focused comparison of absorbent solutions. This comparison encompasses their CO 2 absorption capacity, as well as the advantages and limitations of each group of absorbents in the integrated system. The role of reactive capture of amino acids in integrated electrolysis is also highlighted briefly. Finally, the review aims to assess the technology readiness level of the integrated CO 2 electrolysis and guide future research towards the development of an efficient and scalable technology.
