Abstract
Integration of CO2 capture and CO2 conversion through electrochemical processes has emerged in recent years, offering a distinct advantage over the traditional independent methods by obviating the costly capture media recovery and compression steps. This review aims to provide a comprehensive overview of this promising research area. State-of-the-art studies of strategies involving independent processes, coupling in a single electrolytic cell, and integration into two electrolytic cells for CO2 capture and conversion are discussed. Furthermore, the energy and production costs for three alternative methods are assessed and compared to highlight the benefits of integration systems. In addition, our personal perspectives on the challenges and opportunities in this emerging field, including achieving high faradic efficiency and low cell voltage, seawater exploration, and membrane-less configuration for high-durability applications, are presented.
