70 years of Fraunhofer

With our fascination for research, we are discovering the world of tomorrow. And the day after tomorrow. It is the future that drives the Fraunhofer-Gesellschaft. We ask the right questions and find new answers: Solutions that are of immediate benefit to industry and society.



Greenhouse gas sulfur hexafluoride (SF6) in the energy sector

New study on the use of the greenhouse gas sulfur hexafluoride (SF6) in the energy sector started. Sulphur hexafluoride (SF6) plays an important role as an insulating gas in electrical switchgear at various voltage levels when interrupting and diverting current flows. At the same time, it is one of the most effective greenhouse gases with a very long lifetime and, although the concentration of SF6 in the atmosphere is currently still very low, it accumulates steadily over the years.



Annual awards of Energy Systems Integration Group

The Energy Systems Integration Group (ESIG), the leading source of global expertise for energy systems integration and operations, announced the winners of its 2019 Excellence Awards. Dr. Bernhard Ernst from Fraunhofer IEE in Germany is one of the winners for his contributions to international renewable energy standards development efforts.  



The two branches of Fraunhofer IWES are to become independent

Since its founding in 2009, the Fraunhofer Institute for Wind Energy and Energy System Technology IWES has grown to almost 600 employees. As part of their strategic development and alignment, both divisions of the institute have developed largely independent profiles. The Executive Board and Senate of the Fraunhofer-Gesellschaft have therefore decided to continue the branches of the institute as independent institutes as of January 2018: as IEE and IWES. For customers and industry partners, the sharpening of the profile will facilitate a clear allocation of activities.
