Details from my notes, rather old and not sure how accurate they are now due to electrolyte efficiency advancements,in recent years, but probably reasonably good ball park figures.
1MW.h of energy storage is said to use between 4-4.5 Metric Tonnes of Vanadium (MTV)
1 MTV = 1.78 MT of V2O5. 1 MTV = 8 MT of Vanadium Electrolyte - dry weight comes out at around one eighth of the fluid weight,
‘Twas what he said - but as we all know, it’s going to depend on the what the BE spin off arrangements do to the market perceptions and by definition , the sp. We need that BE spin off info, everything hinges on that and we ain’t gonna know because of the timing of this meet!
@ eatstocks, spot on, but let’s now see what the results are when they open over there - and also how todays investor meet q&a session pans out … very disappointingly with no RNS released on the BE issues - it doesn’t look like it’s going to be as usefully informative as it might of been if took place after the news release. Another deliberately arranged poor comms tactic?
Best wait and see, it maybe all genuine but some of those posts looks to me like they’re coming from a suspiciously concocted effort - all the hallmarks of a typical p&d exercise.
But it’ll be good publicity if it attracts a wider American pi base.
@ Pat48, if they’re going to discuss anything that’s deemed to be sp sensitive news on that subject, I think they’ll have to issue an RNS first. Maybe they intend issuing an RNS between now and then?
Also, I believe (maybe wrongly) that today is supposed to be the last day for MUST to announce to the market what their current rto situ is with the FCA - is and if or not another extension is going to be required.
Hydrogen is only labelled ‘Green’ when it’s produced from renewable energy sources such as wind, solar or tide, which are obviously not a constant. Otherwise it’s grey or blue which are classed as ‘dirty’ production processes.
The electrolysis process needs a storage battery for the times when the sun doesn’t shine, the wind doesn’t blow and the tide is between its ebbs and flows. The benefits of a tidal source of energy is that it’s 100% predictable - that obviously isn’t the case with wind and solar.
Due to fact that the electrolysis process cannot be continually stopped and restarted its vital that is has a constant flow of power and battery that’s capable of doing the ‘heavy lifting’ and supplying the power - possibly for long durations of time- and more than just once every 24 hours - can charge and discharge virtually forever and those benefits are why the green hydrogen project in Orkney chose to use an Invinity VRFB.
This project in this article was completed, commissioned and is in full production.

Hydrogen is also more likely to used as a fuel as an alternative to LPG rather than an energy storage medium - although it can also be used for that IF it can be made efficient and economical. Currently that doesn’t appear to bd the case.
Your research will have informed you that the ELZ electrolyte plant is a joint development with IDC that’s scheduled to start production of electrolyte in commercial volumes by the end of H1 next year. Probable project construction/installation costs around $20 million but DDYOR.
As it’ll be the only electrolyte plant on the African continent which consists of over 50 countries - future value of the completed plant will depend on the volume of electrolyte orders it receives from the predicted lift off of the African continent mini-grid industry once the project is completed and production gets underway.

Eskom decided to finance, own and operate the renewables solution for Komati to gain
valuable experience to operate these technologies to speed up future renewables integration as
well as to learn how to manage the transition for Eskom worker and contractors to mitigate
socio-economic impacts. However, the utility acknowledges potential private sector
participation opportunities in repurposing other coal power plants that are planned for
retirement, recognizing that this would contribute to minimizing the impact of the repurposing
activities on both the national fiscus and Eskom's balance sheet. To that end, the project will
provide US$3 million of grant financing that will enable Eskom to procure the services of a
Financial Advisor (FA) to provide financial advisory services to use private sector or PPP
financing for future coal plant repurposing.

The World Bank Releases Project Document to Repurpose Komati Coal Fired Power Station - Green Building Africa.
The World Bank's Proposed Development Objectives are to decommission the Komati coal-fired power plant, repurpose the project area with renewables, and create opportunities for
workers and communities during the transition process.
• The repurposing project is expected to cost US$ 497 million, the majority of which will be
footed by the World Bank's International Bank for Reconstruction and Development (IBRD).
In the first phase, 100 MW solar PV, 50 MW wind and 150 MW batteries are planned to be installed using infrastructure provided by Eskom (access roads, cable routes, transformer, etc.).
Theconversion of one 125 MW generator unit to a 100 megavolt amperes reactive (MVAR) synchronous condenser with a flywheel will be added as part of phase 1.
Phase 2 involves the original power plant and Ash dams (123 ha). Once the main Komati plant and associated facilities are demolished and together with the ash dams rehabilitated, phase 2 of repurposing will include the installation of an additional 50 MW solar PVs and 20 MW of wind.
At this stage Eskom is also planning to add the conversion of the two remaining 125 MW generator units to 2x 100 MVAR synchronous condenser with a flywheel each to Phase 2. The 200 MVAR synchronous condensers capacity will absorb and produce reactive power to stabilize and strengthen the power system.
Phase 2 repurposing can only be implemented once the
decommissioning is completed, the sites are cleaned up, and the repurposing design is consistent with the environmental remediation and closure plans.
The repurposing of Komati with 70 MW wind and 150 MW of solar PV will produce 492 GWh
of energy annually.

Ok, but it’s Vanchem, where there is said to be a lack of site room for a mini-grid and which is having to use diesel generators during load shedding periods and other options are needing to be being considered, nothing to do with waiting for electrolyte production.
Vametco is where the mini- grid is under construction,
I’ve never seen any suggestion of them waiting until they can use their own electrolyte before installing a min- grid.. My understanding is the main obstacle is lack of ‘footprint’ room within their site boundaries.
