Abstract：

The　substitution　of　traditional　fossil　fuels　with　renewable　energy　sources　is　a　crucial　endeavor　for　achieving　carbon　neutrality　targets.　However,　the　intermittency　of　solar,　wind,　and　other　renewables　poses　significant　challenges　to　the　power　grid.　Power-to-X　(P2X)　technologies　play　an　essential　role　in　enabling　the　efficient　consumption　of　renewable　energy.　High-temperature　solid　oxide　electrolysis　cells　(SOECs)　to　convert　CO2　offer　a　promising　method　for　CO2　conversion,　allowing　renewable　electricity　to　be　stored　in　chemical　form　and　facilitating　the　resourceful　utilization　of　carbon　resources.　In　this　paper,　the　mechanism　of　CO2　reduction　through　SOECs　is　reviewed,　two　pathways　for　converting　CO2　to　chemicals　via　SOECs　are　summarized,　and　the　current　markets　and　manufacturers　of　SOECs　are　elucidated.　Based　on　this　discussion　and　analysis,　the　main　challenges　and　development　directions　for　the　large-scale　application　of　SOECs　in　CO2　conversion　are　further　proposed.　©　Higher　Education　Press　2025.
