Batteries in the distribution grid

The second flagship project, „Batterien in Verteilnetzen“ (“batteries in distribution grids”) aims to use, store or feed-in electricity as required, in particular from solar plants, to relieve the electricity grid. In addition, using batteries directly in the distribution grid can also help improve grid operation, thereby reducing the cost of expanding the grid.

Key research topics include electrical or electrochemical systems for storing electrical energy, such as batteries, redox flow or double-layer capacitors, and mechanical storage systems, such as compressed air storage, pumped storage power plants or flywheels. Other projects being funded include new storage concepts and research into connecting decentralized storage systems.

Example projects:

  • In the “Smart Region Pellworm” project, a stable, cost-efficient and market-led electricity supply is to be developed based on renewable energies and using a hybrid storage system. The joint project will also provide grid services with the storage system (project partners: E.ON Hanse AG, Gustav Klein GmbH, Saft Batterien GmbH, Fachhochschule Westküste, Fraunhofer Advanced System Technology AST and RWTH Aachen University).
  • In a joint project with Eisenhuth GmbH & Co. KG and the Clausthal University of Technology, researchers are investigating new types of bipolar plates and sealing materials for redox flow batteries. By optimising the manufacturing processes, an important contribution can be made to increasing the efficiency of the components for redox flow batteries and producing them cost-effectively.
  • In future, batteries will have to be elaborately linked and partly scaled up to form larger units. Since both will bring new challenges, the joint project between the Karlsruhe Institute of Technology, Heraeus Quarzglas GmbH & Co. KG, Freudenberg Forschungsdienste KG and the Martin Luther University Halle-Wittenberg will explore and improve the components of vanadium redox flow batteries and create new test facilities for testing these materials.

The subsidised junior research groups include basic research at Ruhr-Universität Bochum, the University of Münster, the Leibniz Institute for New Materials in Saarbrücken, Ulm University and the Centre for Solar Energy and Hydrogen Research in Ulm.
