And so it begins...., page-38

My take is that for battery grade - 99.5% - it would be $3 to $5 per pound higher than 98% min grade V205. The reason is simply that if the price is too high then, and despite vanadium been better in the large scale energy storage stationary market than say lithium batteries, other sources will be used. If the price of 99.5% grade vanadium is above US$20 per pound I personally feel uptake in the VRB market will be reduced IMO. I explained my opinion in these posts:

Provided the price of electrolyte is reasonable, takeup of of VRBs is expected to be positive in the 2020s IMO, but as I have indicated in the past I just would prefer we target steel in the now and worry about VRBs later.:

Other posters may have a view, but the above is my simple view based on limited understanding of VRBs etc etc and the competition.

All IMO
