Kurzfassung

Advanced technologies, optimized operation and infrastructure are not sufficient 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 was investigated and evaluated. Hydrogen can be generated by water electrolysis from fluctuating renewable power sources. Together with CO2 – e.g. sequestrated from industrial resources – the reverse water-gas-shift reaction forms syngas. The Fischer-Tropsch synthesis produces long chained hydrocarbons from syngas. Downstream product separation and upgrading generates gasoline, jet fuel and diesel. Another process concept is based on high temperature co-electrolysis of steam and CO2 producing synthesis gas at high temperature and pressure. 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 plant capacity was set to 60 t/h of product. A baseline Power-to-Fuel efficiency of 44 % was calculated for the concept based on water electrolysis. The carbon conversion was 73 %. The co-electrolysis concept achieves a Power-to-Fuel efficiency of 60 % and a carbon conversion of 98 %. The sensitivity of various operation conditions was analyzed. A cost analysis based on market data and equipment factors was performed. Employing stationary power input of 105 €/MWh, production costs of 3.38 €/kg were found for the water electrolysis concept. The production costs of the co-electrolysis concept compare to 2.83 €/kg. 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.
