About
VoltStorage was a Munich-based developer of next-generation stationary flow batteries, pioneering iron salt redox flow technology for long-duration storage of renewable energy. Founded in 2016, the company developed cost-efficient and resource-saving battery storage solutions to make solar and wind power available around the clock. Its iron salt battery targeted utility-scale and distributed energy storage applications as a sustainable alternative to lithium-ion. The company raised over €66 million before shutting down in 2025, with its IP and assets acquired by US-based ESS Inc.
