Vanadium-Energiespeicherindustrie

Ein Vanadium-Redox-Flow-Energiespeicher von Invinity besteht aus zwei Tanks mit in Wasser gelöstem Elektrolyt. Diese sind durch eine Protonenaustauschmembran voneinander getrennt. Beide Elektrolyte sind Vanadium in unterschiedlicher Oxidationsstufe. Beim Laden und Entladen werden die Vanadium-Ionen zwischen den Oxidationsstufen bewegt.

Which material is used to make vanadium flow batteries?

Samantha McGahan of Australian Vanadium writes about the liquid electrolyte which is the single most important material for making vanadium flow batteries, a leading contender for providing several hours of storage, cost-effectively.

How much vanadium will be produced by 2031?

The VRFB deployment forecast by Guidehouse Insights would equate to between 127,500 and 173,800 tons of new vanadium demand per year by 2031, according to Vanitec calculations based off Guidehouse’s projection. That would be more than twice as much vanadium as is currently produced annually today.

What materials are used to make vanadium redox flow batteries?

Image: CellCube. Samantha McGahan of Australian Vanadium writes about the liquid electrolyte which is the single most important material for making vanadium flow batteries, a leading contender for providing several hours of storage, cost-effectively. Vanadium redox flow batteries (VRFBs) provide long-duration energy storage.

Is vanadium a critical raw material?

The European Commission identified and formally registered vanadium on the 2017 list of Critical Raw Materials for the European Union, while the United States, Canada and Australia have also listed vanadium as critical to supporting their economies.

Are VRFBs a major source of new demand for vanadium?

Many vanadium industry stakeholders see VRFBs as a major source of new demand for the metal that has traditionally been used in steel alloys,” states Mikhail Nikomarov, Chairman of the Vanitec Energy Storage Committee (ESC) and CEO of Bushveld Energy.

Can vanadium be used in VRFBs?

Vanitec, the not-for-profit international global member organisation whose objective it is to promote the use of vanadium-bearing materials, says that while vanadium is mainly used within the steel industry, vanadium is increasingly being recognised for its use in VRFBs.
