Integration of Solid Oxide Electrolyzer and Fischer-Tropsch: A sustainable pathway for synthetic fuel

Based on experimental results on a Solid Oxide Cells stack operated in co-electrolysis, three system-level models were developed, evaluating the most performing option. Thus, considering a plant capacity of 1 bbl/day of liquid fuel, in the best scheme, the electricity-to-liquid efficiency was estimated to be 57.2%. Materials introduced into the system are simply water (33,701 ton/MJ) and carbon dioxide (79,795 ton/MJ). While hydrogen is necessary to feed the SOE, net consumption is zero because it is recovered from Fischer-Tropsch product lighter fraction.
