Additional information

EWE Gasspeicher GmbH, a wholly owned subsidiary of the Oldenburg-based utility company EWE, plans to build the world’s largest battery by employing the well-known redox flow battery principle – in which electrical energy is stored in a liquid – along with new, environmentally friendly components in underground salt caverns. These kinds of caverns are currently used to store natural gas. EWE GASSPEICHER is collaborating on the project – brine for power (b4p for short) – with the Friedrich Schiller University in Jena, which developed the innovative components. It uses salt water and recyclable polymers (plastics).
