New All Liquid Iron Flow Battery For Grid Energy

Are vanadium redox flow batteries the future?

Called a vanadium redox flow battery (VRFB), it's cheaper, safer and longer-lasting than lithium-ion cells. Here's why they may be a big part of the future — and why you may never see one. In the 1970s, during an era of energy price shocks, NASA began designing a new type of liquid battery.

Is vanadium a viable alternative for energy storage?

China is the world's biggest consumer. Its weak property sector has contributed to the mineral's price weakness. But vanadium is also shaping up as a viable alternative for energy storage, especially over long timeframes. Vanadium redox flow batteries (VRFBs) are big and have poor energy density, ruling them out for electric vehicles and gadgets.

Could vanadium be a new source of energy?

Life has been tough for vanadium bulls, given the impact of sluggish steel demand. But now, its potential use in batteries could add a new source of demand. While governments have set more store by vanadium than markets, its role in storing energy could yet change that.

Will flow battery suppliers compete with metal alloy production to secure vanadium supply?

Traditionally, much of the global vanadium supply has been used to strengthen metal alloys such as steel. Because this vanadium application is still the leading driver for its production, it's possible that flow battery suppliers will also have to compete with metal alloy production to secure vanadium supply.

Are vanadium batteries cheaper than lithium-ion?

Since they're big, heavy and expensive to buy, the use of vanadium batteries may be limited to industrial and grid applications. According to Dr Menictas, VRFB batteries work out cheaper than lithium-ion for these applications. "As you start increasing the storage time, vanadium becomes cheaper," he said.

What is vanitec redox flow battery (VRFB)?
