Production of fuels from low carbon electricity and from carbon dioxide by the use of a solid oxide electrolysis cell (SOEC) and Fischer-Tropsch is shown. Fischer-Tropsch is an exothermic reaction that can be used to produce steam. Steam produced from the Liquid Fuel Production (LFP) reactor system, where the Fischer-Tropsch reaction occurs, is used as feed to the SOEC. The higher temperature steam improves the efficiency of the overall electrolysis system. The integration of the LFP steam improves the efficiency of the electrolysis because the heat of vaporization for the liquid water does not have to be supplied by the electrolyzer.
