Fraunhofer facility designs CO2 capture for Lusatian e-fuel plant

Following a national call for tenders, the PtX Lab Lausitz has commissioned the Fraunhofer Research Institution for Energy Infrastructures and Geothermal Energy IEG to develop a direct air capture process for its planned PtL pilot plant.

Low emissions even at lofty heights. A pilot plant in Lusatia for the production of synthetic kerosine based on green hydrogen is to show how this goal can be achieved. A key factor in this is, of all things, the sustainable extraction and use of pure CO2, which is needed for the power-to-liquid fuel. The best possible process for capturing the CO2 from the air using the so-called direct air capture (DAC) method will be anlysed by experts in the coming months. The PtX Lab Lausitz had invited tenders for the relevant services throughout Germany. The Fraunhofer Institute for Energy Infrastructures and Geothermal Energy IEG has now won the bidding process. The first meeting on 11 November marked the start of the work.

Large-scale processes based on known technologies

In the coming months, the Fraunhofer researchers will conduct a study to determine the best process for extracting CO2 from the ambient air at the plant. The aim of the project is to develop a scalable, large-scale DAC process based on established technologies and procedures. The study is scheduled to run for 13 months. The results will provide an indispensable basis for the construction of the pilot plant.

Dr. Harry Lehmann, head of the PtX Lab Lausitz, said at the start of the study: "According to the current state of knowledge, the direct air capture process represents the most sustainable solution for obtaining the CO2 required for the production of synthetic fuels and basic materials. We are pleased that the researchers at the IEG are supporting us in the development of a plant that meets the highest standards of sustainability. The commissioning of another facility from Cottbus also shows how much expertise in the development of future technologies has already been built up in Lusatia in the meantime." 

CO2 as an important raw material for saving CO2

CO2 is needed as a raw material for the production of synthetic fuels and also as a basic building block for the chemical industry. The DAC process helps to meet climate targets because it can reduce the CO2 concentration in the atmosphere.
