Department Electrolysis und Batteries

With the increasing generation of electricity from renewable sources, the problem of storage and defined provision of energy is becoming more and more important. The use of hydrogen as an indirect storage medium and the use of batteries for direct buffering of electrical energy are two possible approaches to solve these problems. Hydrogen production by electrolysis is therefore an important focus of the department. In addition, hybridisation, i.e. coupling with other energy systems such as batteries, is becoming increasingly important in the field of fuel cell systems. Consequently, the development of innovative battery technologies, which are particularly suitable for combination with fuel cell systems, is another focus of the department.

For our work we have an extensive infrastructure at our disposal, which allows us to both research the production of the individual components and validate the results in a realistic environment.

• Outdoor area with the possibility to set up and test container-based electrolysis systems up to approx. 150 kW electrical connected load
