Ulf Herrmann

Scientific Manager Integrated District Planning

Professor Ulf Herrmann is Scientifc Manager of the Competence Center Integrated Neighborhood Planning at Fraunhofer IEG. In his his main position, he has been Professor and Head of the Solar Institute Jülich at Aachen University of Applied Sciences since 2014. After studying mechanical engineering, specializing in energy and heat technology, at RWTH Aachen University, he first worked as a research assistant at BTU Cottbus and the Center for Solar Energy and Hydrogen Research, Stuttgart, where he completed his doctorate in cooperation with RWTH Aachen University. Subsequently, during his 14 years in industry, he developed solar power plants for worldwide use. During this time, he began to work on the system-serving design of plants and, in particular, advanced the development of storage systems and hybrid solutions. In various management positions he has also been involved in the development of organizations. For example, he established and managed a corporate office in the USA for more than 2 years.

He is active in several regional committees on the energy transition, sustainable energy supply and structural change and advises the state government of NRW on these topics. At IEG, he will now further expand his research activities in the field of holistic sustainable energy supply systems with a focus on neighborhoods.
