Redox-flow batteries (RFBs) are emerging as a key technology for stabilizing renewable energy systems. They store energy in liquid electrolytes contained in external tanks, allowing flexible scaling of capacity and long operational lifetimes. This makes them ideal for medium-duration energy storage—bridging the gap between short-term lithium-ion batteries and long-term hydrogen solutions.
Germany is a global leader in RFB development, driven by research institutions such as the Fraunhofer Institute for Chemical Technology and several specialized companies. Dr. Jens Noack emphasizes the importance of international standardization, particularly within the IEC and EU frameworks, to ensure quality, comparability, and interoperability of systems and materials.
Through innovation and coordinated standardization efforts, Germany aims to strengthen its role as a “hidden champion” in redox-flow technology and support a more resilient, sustainable energy infrastructure.
