Techno-economic performances of Norwegian biojet fuel production via the Alcoholto- Jet and Fischer-Tropsch synthetic paraffinic kerosene routes were estimated based on adaptations of available literature data to Norwegian conditions. This paper reviews the deployment of feasible routes to sustainable jet fuel production for the short-to-medium term timeframe (2020-2025), with an emphasis on the Norwegian landscape. Given the fact that there are serious concerns regarding the availability and the sustainability of large-scale biofuels production both from oil seed plants and carbohydrates (sugars and starches) as well as the unsuitability of the Norwegian climate for oil seed or sugar/starch plant cultivation, only biojet fuels produced from lignocellulosic resources are considered. The short-to-medium term implies certified or near certified fuels. The most promising and feasible alternatives for Norwegian biojet fuel production are hence limited to FT-SPK and ATJ. The results suggest that, from a techno-economic point of view, production of jet fuel via the gasification-FT route is more favorable than the alcohol to jet fuel route. This is attributed to the inclusion of the alcohol production step. Feedstock price is the main operating cost for both of the routes. The current cost of production of jet fuel under Norwegian conditions for gasification FT route is estimated between 43 USD/GJ and 47.4 USD/GJ, and for the ATJ route, between 54 USD/GJ and 60 USD/GJ.
