Q10. Anything closer to home?
Invinity Energy Systems plc (AIM:IES) is a manufacturer of vanadium flow batteries for large-scale energy storage. It was formed in 2020 from the merger of Avalon Battery Corporation (US) and redT energy (UK), and supported by BMN funding (Bushveld holds 8.71% of the company). Invinity is involved in the Energy Superhub Oxford, targeting a 2MW/5MWh flow storage battery to complete a 52MW lithium-flow hybrid.

Other significant players include Cellcube, Delectrik, H2, Rongke Power, Sumitomo, UniEnergy Technology, VoltStorage, VRB Energy and Vionx.
Q11. What's all the talk about Eskom?
A. Eskom is a South African electricity public utility, the largest electricity producer in Africa. In 2019, it was announced that Eskom was to be split up into three nationally owned entities due to huge debts and poor reliability. This is leading to various major initiatives to develop independent power production, and large-scale energy storage systems. Trial VRFB systems, delivered by China's Rongke Power, are under commissioning. Major related contracts are being tendered with Eskom at this time, and by the end of 2020 there should be better visibility of BMN's involvement. These are expected to lead to the rollout of VRFB systems to support substantial new wind and solar power generation in South Africa, assisted by World Bank funds. The World Bank is meanwhile embarking on a $5billion 17,500GWh battery storage programme.
Q12. Management and posters talk about BMN targeting "vertical integration". What does this mean?
A. BMN is positioning itself as a major company which:
(a) mines, extracts, and sells a significant and rising fraction of the world's vanadium;
(b) is developing a substantial manufacturing facility in South Africa (in the East London Industrial Development Zone, ELIDZ) to provide the high-purity electrolyte to be used in VRFBs;
(c) is linking up with VRFB manufacturers to establish large-scale energy storage systems (batteries).
This vertical integration allows BMN to profit from the entire supply chain from mining, processing and sale of the vanadium, vanadium electrolyte and VRFBs.
BMN's (first) vanadium electrolyte plant, in East London (SA), is initially targeting 200 MWh annually, with possible expansion to 1000 MWh.
In summary, VRFBs are fast gaining traction for large long duration grid scale applications due to their superior charge and discharge qualities with no degradation, very high safety (zero fire risk), and low cost (per kWh stored). BMN's vanadium electrolyte rental model significantly reduces upfront capital cost. After say 20yrs the electrolyte can be re-sold to the steel market or reused as electrolyte, giving BMN strong long-term revenue growth.
The recent launch of Largo Clean Energy (by Largo Resources), created the world's second vertically-integrated VRFB business, following the lead taken by BMN (08-12-20). <<<
