Does VRB energy have a vanadium redox flow battery?

In mid-July, China's National Photovoltaic and Energy Demonstration Experimental Center began testing VRB Energy's vanadium redox flow batteries at its Daqing facility in northeastern China. VRB Energy claims its vanadium redox flow storage systems rely on low-cost ion-exchange membrane and bipole material, and long-life electrolyte formulation.

Could a vanadium redox flow battery solve storage problems?

A type of battery invented by an Australian professor in the 1980s has been growing in prominence, and is now being touted as part of the solution to this storage problem. Called a vanadium redox flow battery (VRFB), it's cheaper, safer and longer-lasting than lithium-ion cells.

Will introducing vanadium batteries reduce peak energy prices in Australia?

"Introducing vanadium batteries will reduce peak energy prices in Australia. "When electricity prices are negative, we'll be buying the electricity and that will help stabilise the grid, and when prices are high, we'll be selling power into the grid — that margin will have the effect to reduce prices. "We're on the verge of a vanadium revolution."

Does vanadium degrade?

First, vanadium doesn’t degrade. “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,” says Brushett.

Why are vanadium batteries more expensive than lithium-ion batteries?

As a result, vanadium batteries currently have a higher upfront cost than lithium-ion batteries with the same capacity. Since they're big, heavy and expensive to buy, the use of vanadium batteries may be limited to industrial and grid applications.

Can flow batteries be used for large-scale electricity storage?

Associate Professor Fikile Brushett (left) and Kara Rodby PhD ’22 have demonstrated a modeling framework that can help speed the development of flow batteries for large-scale, long-duration electricity storage on the future grid. Brushett photo: Lillie Paquette. Rodby photo: Mira Whiting Photography
