Part 4
"We've had the World Bank group coming out and committing $1 billion to finance a certain level of energy storage by 2025?"
"They've committed $1 billion. They've also indicated they intend to leverage that up to $5 billion and what's particularly interesting is the fact that they referred to battery technologies - energy storage technologies specifically. They are great because of the fact that they can be deployed flexibly and so Africa's energy needs, not just Africa but emerging markets or developing countries they tend to have sparse populations and distributed generation solutions typically are quite attractive in that space, and when you are talking about distributed generation solutions where you don't have long distance transmission infrastructure (switch support?) to pair renewables with energy storage solutions. So that's a very exciting development for us and again an opportunity space which we are going to be chasing up very aggressively." (10.18)
"So you're looking to have your first battery commissioned by year end is the target?"
"At Eskom, that's correct."
"With vanadium prices where they are , at or pretty close to all time highs, any concerns there for the outlook for vanadium batteries and Bushveld Energy?"
"Ironically we think that current prices are creating an interesting opportunity for Bushveld Energy. Why I say that, we think that we've always been advocates that the solution for VRFBs is in a vertically integrated business model, particularly when you do it with low cost production capacity that's scalable for vanadium units. The 2 key challenges for VRFBs that we see as eminently solvable. The supply of vanadium into the systems. There is enough vanadium in the ground and with scaled up production capacity particularly and again when you do this on a brown field basis you can do it fairly quickly, you can solve the availability of vanadium for VRFBs. The second part is the input cost of vanadium to VRFBs. The current prices you are talking potentially another 50% so that is high yes and it could potentially make VRFBs expensive if, and its a big if, you looked at VRFB procurement only from a capex point of view. But remember that VRFBs are 20+ year life batteries. The vanadium electrolyte that you put in these systems doesn't degrade over that life and is reusable at the end of the life of the battery. And these are typically large systems so 10 MW hour battery system will typically have about 55 tons of vanadium. So you can secure this you can put in place insurance around it and here is where we think the magic is, you can rent the electrolyte into these systems and in one stroke you can take out a significant part of the capex convert it into opex and you are not taking the full chunk into opex because you still have residual life of the vanadium at the end of that. So it's a product that we will be bringing out into the market and we are very excited about that and we think it's a game changer for VR
