Scientists and engineers in Germany have created the largest battery in the world with redox flow technology.
Redox flow batteries are liquid batteries. The Friedrich Schiller University of Jena has developed a new and forward-looking salt-free (brine) based metal-free redox flow battery. This new development will use salt caverns as energy storage.
Both charged electrolytes can be stored for several months. The maximum storage capacity of this redox-flow battery is limited only by the size of the storage containers for the electrolyte liquids.
The project is being ramped up now, going through a test phase before bringing the full system online; they are aiming to achieve this in 6 years. The electrical capacity of 700 megawatt hours will be enough to supply over 75,000 households with electricity for one day.
