Most powerful battery within reach

BERLIN - The German energy provider EWE and scientists from the Friedrich-Schiller University in Jena said on Thursday that they have made progress in their plans to build the world's most powerful battery.

The joint "brine4power" project aims to make use of underground salt caverns to store energy within the next six years. It's hoped that saltwater brine and electrically charged synthetic particles will transform the subterranean cavities into giant batteries by applying a principle known as Redox-Flow.

The team behind the "brine4power" has now presented encouraging intermediary results of their work to press in Berlin.
