Could a vanadium flow battery be a workable alternative to lithium-ion?

Image: Invinity Vanadium flow batteries could be a workable alternative to lithium-ion for a growing number of grid-scale energy storage use cases, say Matt Harper and Joe Worthington from Invinity Energy Systems.

What are vanadium redox flow batteries?

Vanadium redox flow batteries (VRFBs) are stationary batteries that provide long-duration energy storage. They are installed worldwide to store many hours of generated renewable energy. Samantha McGahan of Australian Vanadium discusses the electrolyte, which is the single most important material for making vanadium flow batteries.

Which material is used to make vanadium flow batteries?

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

Does vanadium degrade in flow batteries?

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'.

Will vanadium flow batteries be successful in China?

In that interview, Erik Sardain, then a principal consultant at natural resources market tracking firm Roskill, said that the future success of vanadium flow batteries could hinge on how readily the technology was embraced by China.

How long do flow batteries last?

Valuation of Long-Duration Storage: Flow batteries are ideally suited for longer duration (8+ hours) applications; however, existing wholesale electricity market rules assign minimal incremental value to longer durations.
