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.
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.
One of the main costs affecting vanadium electrolyte is the price of moving it. Essentially when you transport the electrolyte you are moving acid and water. To reduce the cost of the battery, manufacturing the electrolyte close to the installation makes a lot of sense.
USV has an agreement with Europe-headquartered VRFB manufacturer CellCube to supply up to 3 million litres of that electrolyte. In the UK, Oxkem is another electrolyte supplier. It has the capacity to manufacture in excess of 3 million litres per year. Global supply of vanadium electrolyte is however currently very tight.
