Bericht zur Umweltverträglichkeitsprüfung von Vanadium-Flow-Energiespeicherbatterien

Vanadium im Grundwasser und damit möglicherweise auch im Trinkwasser vorkommt, hängt vor allem mit der Bodenart und dem Grad der Bodenentwässerung zusammen. Vanadium findet in der Industrie breite und vielseitige Anwendung (z. B. Metallurgie, Elektronik, Färberei). Die dort effektiv verbrauchten Mengen von Vanadium sind in jedem

What is a vanadium flow battery (VFB)?

In the course of the energy transition, storage technologies are required for the fluctuating and intermittently occurring electrical energy. The vanadium flow battery (VFB) is an especially promising electrochemical battery type for megawatt applications due to its unique characteristics.

Is a vanadium flow battery a good choice for megawatt applications?

The vanadium flow battery (VFB) is an especially promising electrochemical battery type for megawatt applications due to its unique characteristics. This work is intended as a benchmark for the evaluation of environmental impacts of a VFB, providing transparency and traceability.

Does the vanadium flow battery leak?

It is worth noting that no leakages have been observed since commissioned. The system shows stable performance and very little capacity loss over the past 12 years, which proves the stability of the vanadium electrolyte and that the vanadium flow battery can have a very long cycle life.

What is a vanadium redox flow battery (VRFB)?

Batteries are one of the key technologies for flexible energy systems in the future. In particular, vanadium redox flow batteries (VRFB) are well suited to provide modular and scalable energy storage due to favorable characteristics such as long cycle life, easy scale-up, and good recyclability.
