Kopernikus-P2X Phase II: Demonstration of a modular PtL process chain for decentralized production of sustainable aviation fuel at KIT PtX’s Lab

The aviation sector significantly contributes to global greenhouse gas emissions, and achieving the European Union’s 2050 carbon neutrality target requires sustainable aviation fuels (SAF). Power-to-Liquid (PtL) technology, which uses renewable electricity, CO₂, and water, offers a promising route for producing synthetic paraffinic kerosene (SPK) with lower aromatic content, thereby reducing soot and contrail formation.
In the frame of the Kopernikus-P2X project’s second phase, the decentralised production of sustainable aviation fuels (SAF) is being demonstrated at an industry relevant scale. The process chain involves a 220 kW high temperature co-electrolysis for the direct production of syngas. The produced syngas is first compressed before being converted in a FT-reactor into FT-crude. To increase the overall efficiency, offgas and waste heat from the FT-Synthesis are being recycled to the Co-SOEC. The stable operation of the process chain including the recycling of offgas has been demonstrated.
Following the successful operation, the process chain will be upgraded through the implementation of a dual FT reactor configuration and the integration of a downstream refining module based on hydrocracking und isomerisation, aiming to post process the FT-crude to ASTM D7566 standards. ... mehrFurther investigations will focus on the dynamic operation and scalability of decentralized PtL systems for SAF production, aiming to reduce dependence on centralized refineries and facilitate adaptation to local energy conditions.
