Fraunhofer IWES secures investments in technological developments through validation, shortens innovation cycles, accelerates certification procedures, and increases planning accuracy by means of innovative measurement methods in the wind energy and hydrogen technology sectors. At present, there are more than 300 scientists and employees as well as more than 100 students employed at the nine sites: Bochum, Bremen, Bremerhaven, Görlitz, Hamburg, Hannover, Leer, Leuna and Oldenburg. Extensive funding policy support has made it possible to set up unique test benches, for example for rotor blades, drive trains and support structures, bearings, and main shafts as well as a measurement infrastructure and laboratories since the institute’s foundation in 2009. In addition, Fraunhofer IWES systematically researches the interaction of wind energy and hydrogen production, reconversion, and grid integration as well as generating extensive synergies. The test portfolio was developed in close cooperation with leading industrial players, who have also accompanied the development of the test methods and processes right from the design stage. The combination of a globally unique testing infrastructure with methods expertise distinguishes the IWES as a research partner for companies all over the world. Participation in international expert committees makes the institute an active trailblazer for technological developments and quality assurance in the wind industry.
