Swiss company building what it says is world’s most powerful redox‑flow battery in Laufenburg

A Swiss firm is building what it claims will be the world’s most powerful redox‑flow battery in Laufenburg, a town in northern Switzerland. The company describes the installation as the most powerful of its kind to date and says construction is underway in Laufenburg.

The project highlights a push to deploy large, stationary energy storage systems in strategic locations. Redox‑flow batteries store energy in liquid electrolytes that circulate through electrochemical cells, allowing capacity and power to be scaled independently.

Unlike conventional batteries, they are typically used for stationary applications where long service life and flexible sizing are priorities. The firm’s characterization of the Laufenburg project as the most powerful redox‑flow installation underscores growing interest in grid‑scale storage as electricity systems adapt to more variable power generation.

Further details about the system’s capacity and timeline were not included in the brief description.
