CAC is part of a joint project for the production of electricity-based, green kerosene. The Federal Government will support the project over the next three years with some four million euros.

In cooperation with five other partners from industry and science, Chemieanlagenbau Chemnitz GmbH (CAC) is researching the production of environmentally friendly synthetic kerosene. It is also called electricity-based fuel. For the KEROSyN100 research project, CAC undertakes the development of innovative technology for the synthesis of methanol into kerosene. In contrast to conventional fossil fuels, the goal is to produce kerosene by using renewable electricity. Excess wind energy from the windy Western coast of Schleswig-Holstein is used as source of electricity. Up to now, this energy generated has been subject to curtailment and was lost due to grid bottlenecks.

The engineers in Chemnitz take advantage of this abundance. “Instead of wasting excess wind energy, we use it to create the basis for synthetic fuel by means of innovative chemical processes using water and carbon dioxide”, says Jörg Engelmann, CEO of CAC. “In the ideal case, this electricity-based kerosene produced with renewable wind energy and the use of carbon dioxide from the atmosphere allows us to achieve a closed CO2 cycle.”

Since 2008, CAC has been conducting research into synthetic fuel technology together with Freiberg University of Mining and Technology. On the basis of this know-how, the Chemnitz engineers are developing the innovative technology for the conversion of methanol to kerosene. Afterwards, CAC will prepare the basic engineering for a customized demonstration plant at the site of the project partner Raffinerie Heide, which will represent the entire process chain.

After the successful completion of this project, a follow-up project is expected, in order to demonstrate the developed concept at the Heide refinery site and prove the suitability of the green fuel in real flight operations.

Under the leadership of the Advanced Energy Systems Institute (AES) of the University of Bremen, in addition to Chemieanlagenbau Chemnitz GmbH, the industrial partners Raffinerie Heide GmbH and SKL Engineering & Contracting GmbH are involved in the „KEROSyN100“ project. Science partners are the Freiberg University of Mining and Technology, the DLR - Institut für Vernetzte Energiesysteme e.V. (Institute of Networked Energy Systems) and IKEM - Institut für Klimaschutz, Energie und Mobilität e.V. (Institute for Climate Protection, Energy and Mobility)
