Introduction Liquid fuels will be the fuel of choice for air and cargo transport for the coming decades. Synthetic fuels produced by the power-to-liquid route together with CO2 from industrial processes are a promising alternative to biofuels and can contribute significantly to the production of sustainable liquid fuels. Different process routes using hydrogen obtained by electrolysis from renewable power sources combined with Fischer-Tropsch process are analyzed by process simulation. Results Integration of SOEC with the FTS is highly advantageous in terms of process efficiency. The high pressure steam that is obtained by cooling of the FTS can be used as input for the SOEC that can in this way attain an electrolyser efficiency (electrical) of >95%. The total system efficiency calculated for Power-to-Liquid can be more than 60% for optimal conditions and unit operations. Discussion and Conclusion A sustainable pathway for the production of synthetic liquid fuels is technically feasible. The fluctuating power supply from renewable sources poses questions with regard to system design, operational characteristics and economic viability that will be discussed.
