“…The pathway for the CO 2 /H 2 O coelectrolysis is still debatable. It is widely accepted that the RWGS reaction definitely takes place under the coelectrolysis conditions, which is responsible for the conversion of CO 2 to CO. Based on experimental results, Li et al speculated that CO was mainly generated through the RWGS reaction with H 2 O electrolysis as the dominant reaction based on the experiment results under three conditions: CO 2 electrolysis, H 2 O electrolysis, and CO 2 /H 2 O coelectrolysis. A simulation study showed that CO was either consumed from the WGS reaction or produced from RWGS .…”

Highly efficient coelectrolysis of CO 2 /H 2 O into syngas (a mixture of CO/ H 2 ), and subsequent syngas conversion to fuels and value-added chemicals, is one of the most promising alternatives to reach the corner of zero carbon strategy and renewable electricity storage. This research reviews the current state-of-the-art advancements in the coelectrolysis of CO 2 /H 2 O in solid oxide electrolyzer cells (SOECs) to produce the important syngas intermediate. The overviews of the latest research on the operating principles and thermodynamic and kinetic models are included for both oxygen-ion-and proton-conducting SOECs. The advanced materials that have recently been developed for both types of SOECs are summarized. It later elucidates the necessity and possibility of regulating the syngas ratios (H 2 :CO) via changing the operating conditions, including temperature, inlet gas composition, flow rate, applied voltage or current, and pressure. In addition, the sustainability and widespread application of SOEC technology for the conversion of syngas is highlighted. Finally, the challenges and the future research directions in this field are addressed. This review will appeal to scientists working on renewable-energy-conversion technologies, CO 2 utilization, and SOEC applications. The implementation of the technologies introduced in this review offers solutions to climate change and renewable-power-storage problems.
