As grid-scale energy storage demands grow, particularly for long-duration storage, so will the need for flow batteries. This increased demand will lead to a challenge with vanadium. Rodby explains, 'Vanadium is found around the world but in dilute amounts, and extracting it is difficult.'
Adding more electrochemical cells and increasing the amount of the electrolyte solution enables to increase power and storage capacity, respectively, of the vanadium flow redox battery. “Energy storage is an emerging sector in constant development that is reshaping the renewable energy market.
Vanadium flow batteries show technical promise for decarbonizing the power sector. High and volatile vanadium prices limit deployment of vanadium flow batteries. Vanadium is globally abundant but in low grades, hindering economic extraction. Vanadium's supply is highly concentrated as co-/by-product production.
Vanadium does not degrade in flow batteries. According to Brushett, 'If you put 100 grams of vanadium into your battery and you come back in 100 years, you should be able to recover 100 grams of that vanadium—as long as the battery doesn’t have some sort of a physical leak'.
In flow batteries, vanadium does not permanently cross-contaminate the electrolytes. If some vanadium flows through the membrane to the other side, it only causes a shift in the oxidation states, which can be easily remedied by rebalancing the electrolyte volumes and restoring the oxidation state via a minor charge step.
And so, almost by default, lithium-ion became the technology of choice for grid energy storage. Now, however, that's begun to change. When a commercial district in Trondheim, Norway, recently commissioned battery energy storage, it made an unusual choice. Instead of ordering lithium-ion, it went with VRFB.
Redox flow battery technology has received much attention as a unique approach for possible use in grid-scale energy storage. The all-vanadium redox flow battery is currently one of the most ...
In order to investigate UV-Vis absorption spectra in general and to determine the SOC from UV-Vis absorption spectra, vanadium electrolyte solutions were prepared ex situ: vanadium electrolyte solution containing solely vanadium species in the V(II) oxidation state and vanadium electrolyte solution with solely V(III) were combined to obtain mixtures with SOCs between 0 …

Among the winning candidates, Dalian Rongke, Welead, Flow Energy Storage, State Grid Electric Power Research Institute Wuhan Nari and Shanxi Guorun Energy Storage were shortlisted. Judging from the bidding prices of the five companies, the average unit price of the all-vanadium redox flow battery energy storage system is about 3.1 yuan/Wh.
For these reasons, despite some attempts to provide grid services, to date such ESS were never actively exploited to provide energy for long-term storage . Instead, the VRFBs can represent an effective solution. These batteries store the chemical energy by using a mixture of vanadium compounds dissolved in sulfuric acid.

These emerging applications for vanadium, whether in the form of a vanadium flow battery or as a hybrid vanadium-lithium battery, means that demand for the critical mineral is expected to accelerate. "Just for grid-scale [storage], the global market today is about 125,000 metric tons of vanadium," Perles said.
