Dynamic is our strength

Prof. Andreas Reuter, Managing Director Fraunhofer IWES: "The wind energy industry stands for dynamic and change. We at Fraunhofer IWES have been a competent and innovative partner for technology development for more than ten years."




Wind turbines with integrated electrolyzer demonstrate sustainable hydrogen production at sea

H2Mare flagship project is supposed to receive more than €100 million funding from the BMBF.



Progress in realization of Hydrogen Lab Bremerhaven

Following the approval of funding for the Hydrogen Lab Bremerhaven at the former Luneort airfield, a general contractor has now been commissioned to design specific layout plans for the facilities.



Fraunhofer IWES puts further bearing test rig into operation

Together with the project partners, Fraunhofer IWES is testing 100 small-scale rotor blade bearings and employing the results to create a database that will help to develop advanced control strategies and condition monitoring systems.



Research rotor blade production at Fraunhofer IWES

Testing and validating rotor blade materials for an optimized manufacturing process: IWES is building research rotor blades in order to test materials directly within the production process and to determine whether these are suitable for series production.



Construction begins on superlative rotor blade test bench

Fraunhofer IWES invests €19 million in the construction of a third rotor blade test rig for XXL blades in Bremerhaven/Germany – for length of 115 meters and more. New methods like biaxial or segmented testing will enhance economic viability further.



How does climate change impact wind farm yields?

Fraunhofer IWES and GERICS launch new research project to investigate climatic changes in wind and their influence on wind energy site assessment.


What truly defines the “IWES spirit”

Describing the culture of an institute in words is no mean feat. It is often a matter of shared experiences, the development of extraordinary approaches, and a common understanding of the expected level of quality. 

Our work generates a practical added value and turns innovative ideas into reality. Find out more – from our employees themselves.
