No posting yesterday... a slight hint of blue so I think the juju did not work. Anyway, great to see the posts on the Nedbank webenair about smirking and big hints, but take a look at the scale ....

Cumulative storage in SA estimated over 20 years to be 240GWh.
If I remember rightly, it takes around 4.5 tonnes of Vanadium per 1MWh
- just for context, if that was all VFRB that is over 1 Million Tonnes !!!!! .. over 20 year ... just for SA
In the next 5 years, the estimate growing from 4GWh to 5.9GWh required each year would total 110,000 tonnes of Vanadium
Not all will be VFRB and indeed slide 20 shows SA and California have very similar requirements ... so does California need 1MM+ tonnes over 20 years... and where else in the world
The only way long term anything like these numbers can be met is to grow capacity at primary producers. For us, that must mean at least one complete new mine and refining plant of much larger scale. We have Mokopane and Brits and millions of tonnes of vanadium. No need for it to cost us anything - let the requiring countries put up the money and get it paid back with a reduced cost supply
These presentations and the webenair just demonstrate how big the pot of honey is. We just have to ask how big our spoon is and my guess is very very large - there are no real alternates to this level of storage around now. It wont be Lithium Ion for 2 reasons. First the vast fire risk and 2nd there would be little capacity for EV electrification. At present the majority future demand can practically only be VFRB
