Hydrogen from the biorefinery

The Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB) recently started operating a pilot plant at our site that produces green hydrogen, among other things, by combining two biotechnological processes. The biorefinery uses rinse water and residues from our production. As Evonik's project manager, I was responsible for providing the infrastructure needed to set up the plant. The Rheinfelden site has been producing hydrogen on site for decades, but only from natural gas, a fossil raw material. The Fraunhofer IGB research project opens up interesting prospects for how green hydrogen could be produced in the future.
