Technical FAQs 4

What is a vanadium redox flow battery?

Vanadium Redox Flow Batteries (VRFBs) have emerged as a promising long-duration energy storage solution, offering exceptional recyclability and serving as an environmentally friendly battery alternative in the clean energy transition. VRFBs stand out in the energy storage sector due to their unique design and use of vanadium electrolyte.

What is the largest flow battery in Europe?

The largest flow battery in Europe is most likely in the low double-digit megawatt-hours. Meanwhile, the largest flow battery in the world, in China, is 175MW/700MWh. Energy-Storage.news asked FlexBase for more information about the technology provider, financing and why it had decided to go so large.

Where is the largest redox flow battery in Europe?

These parameters are unmatched both in Europe and globally. For comparison, the currently largest operational redox flow battery is in China, with 175 MW of power and 700 MWh of capacity. The Laufenburg project will be developed by FlexBase Group in collaboration with Erne Group. Construction work began in May 2025.

Is vanadium electrolyte recyclable?

• Recyclability and circularity: Vanadium electrolyte is not only stable but also recoverable and reusable, as evidenced by U.S. Vanadium ’s 97% recovery rate from decommissioned systems. Research in ScienceDirect further validates the recyclability of key components including membranes and carbon felt electrodes.
