So in one fowl swoop, the World Bank delivered not only 57% of the stationary storage expected to be deployed by 2025 but also specifically battery storage, in developing and middle-income countries. Thus we haven’t even begun to consider what developed countries will achieve in that same timeframe and it is they that are expected to drive the market.
Therefore, the question will battery storage get built has been firmly answered.
So then it comes down to which battery storage technology will dominate. Lazards latest analysis (see below) highlights 3 main battery technologies, lithium-ion, VRFB, and Zinc Flow. Given where we have come from, the cost differences are now minimal. However, on paper lithium-ion still has a small edge over its 2 competitors.
3 key points.
The analysis is global ;
It can’t possibly include the BMN value chain because it hasn’t been published yet.
It does not include a leasing model for VRFB.
The expectation is that lithium-ion will still take the lions share of installations but it is all based on global market considerations. That is not where investors should be focusing. If we zoom in on BMN, the company who for me, will come to be shown as the most effective and streamlined VRFB producer in the market, then we see factors that will completely up end those Lazard figures.
Lets start in SA, thus far the home of $72m of that World Bank battery funding. Lazard states that the global average price for solar +PV is as follows ;
Lithium - $108 - $140
VRFB - $133 - $222
Zinc - $115 - $167
I repeat it is global. That said at the lowest end of all 3 technologies there is now only $25 separating the 3 with VRFB set as most expensive. That $133 figure for the VRFB does not consider a SA based vanadium miner producing SA based electrolyte for a SA based market, and leasing the vanadium. It simply cannot.
If we return to the vanadium 101 presentation and my previous highlighting of the cost breakdown on slide 26. There we see that the vanadium and delivery & assembly costs are around 43% of the total battery cost. The above description, be it simplistic, of BMNs business model, knowledge that is easily findable, clearly shows that in SA at least, it is highly likely that the BMN led VRFB is going to be a force to be reckoned with, and that’s where Eskom and it’s 2000MW energy storage need lives.
However, that SA based VRFB is going to be assembled in SA, which is part of a energy hungry SADC (Southern African Development Community), 13 of its member countries are currently signed up to a free trade agreement based on ‘local content’, and they are all Sub Saharan African countries whose economies fall well within the World Bank criteria of being‘developing’.
