Faramog - the most used figure is 5,000 tonnes per GWh - that is for the standard single acid electrolyte - so 5 Kg per KWh
However I don't think that VRFB manufacturers are going to have to pay the market rates that other users of Vanadium will have to. It is tough luck on them but they are boring industries with only limited (5-6 % per annum) growth potential.
The big growth potential is in VRFB energy storage and there is no way that the V producers are going to let that die on the vine, so they are probably going to be getting Vanadium at 30-40 USD/Kg.
Thus 15 USD a year allows you to use something like 5x35 = 175 USD Worth of Vanadium. The alternative is leaving the Vanadium in the ground. I am happy to offer this kind of leasing price to VRFB manufacturers if it means that in year one we have 100 tonnes leased, in year 2 300 tonnes, in year 3, 1000 tonnes, in year 4, 2000 tonnes, year 5 10000 tonnes
At 3 USD per KgV a year leasing costs, 10,000 tonnes earns 30 Million USD a year. FOR DOING NOTHING.
