Aus verfügbaren Kohlenstoffquellen und erneuerbarem Wasserstoff nachhaltig erzeugtes Kerosin

Kurzfassung

Massive efforts are required to achieve the CO2 mitigation goals agreed on for the aviation sector. Carbon neutral alternative liquid fuels are required to fill the gap towards a carbon-neutral growth from 2020 on. The Power-to-Liquid process is one option to produce synthetic jet fuels from renewable energy. The technical and economic performance of production processes based on renewable electricity and CO2 has to be investigated. The process performance is evaluated via flowsheet simulation models and pinch point analyses comparing the Power-to-Fuel efficiency, which is the fraction of the total electrical energy input chemically bound into liquid hydrocarbons, as well as comparison of carbon conversion into liquid fuels. The sensitivity of various operation conditions was analyzed. A cost analysis based on market data and equipment factors was performed. The sensitivity of the electrolyzer capital cost and electricity prices were analyzed and their effect on the production costs will be presented. Investment and operating costs to fill the gap towards carbon-neutral air transport growth from 2020 on can be predicted based on 2014 costs and technology status. A comparison to other renewable jet fuels regarding land use, feedstock potential and economic measures will be provided.
