Lebenszyklusanalyse (LCA) der Herstellung synthetischen Flug- turbinentreibstoffes aus Biomasse, Strom und CO2

Kurzfassung

According to emissions reduction targets of the aviation sector, future use of alternative green jet fuel becomes necessary. Therefore different production processes for sustainable jet fuels are developed and optimized by the German Aerospace Center. Additionally cost analysis for the operation and construction of appropriate refineries were performed. Howev-er, the environmental impact of the green fuel production was not analysed. To determine the environmental impact of synthetic jet fuel, three production pathways are analysed, by using life cycle assessment (LCA) methods. The expected carbon footprint ranges, for the green fuel production in Baden-Württemberg, are determined by analysing best and worst case scenarios. The result show, that green jet fuel could be produced by using residual straw and waste wood. Electricity using production pathways are only able to produce sustainable jet fuel, if renewable electricity is used. For the production for sustainable jet fuel, utilization of grid electricity is not an option. Additional-ly, feedstock and production potentials for the alternative jet fuel production in Baden-Württemberg are investigated. The requirement of the utilization of electricity for synthetic fuel production is pointed out.
