    What this call funds

    This call funds real-world demonstrations of next-generation battery storage systems that can store energy for more than 8 hours, helping stabilize power grids and reduce Europe's reliance on scarce raw materials. It supports building and testing new battery technologies like flow batteries or metal-air systems at a meaningful scale, along with proving they're safe, economically viable and can use materials sourced in Europe. Two projects will be funded with a total budget of about 18.8 million euros.
