The planned project, which Oldenburg-based EWE Gasspeicher is billing as the world’s largest battery, will involve filling two salt caverns, each of around 100,000 cubic meters in volume, with brine to create a redox flow battery that has capacity of up to 120 megawatts and 700 megawatt-hours.

    whereas previous redux-flow designs were not competitive at scale yet due to a three to eight times higher price factor.
