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.
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.
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.
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.
Because vanadium electrolyte doesn’t degrade, it is an appropriate commodity for leasing. The customer then has an operating expense rather than a capital expense. This also provides comfort to the customer as at the end of the battery’s life the electrolyte belongs to someone else who will then be responsible for retrieving and repurposing it.
