Abstract
The transition toward a sustainable energy framework requires developing innovative methods for fuel generation that utilize renewable resources and decrease carbon footprints. Thus, the review overviews current advancements in solid oxide electrolysis cell (SOEC) technology, specifically focusing on its application in co-electrolysis processes to produce syngas with different H(2):CO ratios, essential for Fischer-Tropsch synthesis. It emphasizes the potential of integrating partial methane oxidation reaction into the electrolysis process. By examining recent developments in electrode, electrolyte materials, and system design, the review highlights how these technological enhancements can reduce energy consumption, improve system durability, and facilitate the integration of renewable energy sources. Additionally, the role of methane assistance in SOECs is discussed, illustrating its impact on operational efficiency. Then, future research directions that could optimize syngas production and expand the applicability of SOEC technology in industrial settings are proposed, supporting the transition to a more sustainable energy landscape.
