Stage 76, Bruchsal
Living of the future with redox flow energy storage
Initial situation
In the BiFlow project, with the support of the Federal Ministry for Economic Affairs and Energy and in cooperation with the Karlsruhe Institute of Technology (KIT) and the Fraunhofer Institute for Chemical Technology (ICT), a future-oriented power and heat supply is to be developed for the Stage 76 dormitory.
Solution
The combination of a lithium-ion and a redox flow battery creates a hybrid system. The overall efficiency of the vanadium redox flow battery is increased to 80% with the help of a novel thermal coupling module. Thanks to the stability of the electrolyte at higher temperatures, the vanadium redox flow battery can also be used for heat storage. For cost-efficient and space-saving sector coupling.

Vanadium redox flow battery for grid stabilization
Initial situation
Due to fluctuating consumers and natural fluctuations in renewable energy generation, there are strong voltage fluctuations in the grid.
Solution
In a modified 20' sea freight container, a vanadium redox flow battery including grid-stabilising voltage control was installed directly at the grid end point in an open field. Surplus energy is stored here and can be fed back into the grid when needed.

Car park of the future
Initial situation
As part of the "Sol-LIS-Flow-Net" project, which is funded by the state of Baden-Württemberg, a decentralized solar power generation, an energy storage system and an e-charging network are to be integrated into the company's car park.
Solution
A carport with an integrated solar roof generates electricity, which is buffered by an innovative vanadium redox flow battery. This supplies an intelligent charging infrastructure for at least 10 electric vehicles, expandable to up to 50 charging points. The vanadium redox battery serves as the energy backbone of the system.
