The suggestion that it is for "performing new tricks, and delivering new services to the Australian grid." could be interpreted as a rather ham-fisted attempt and damage limitation.

What do you lot think ?

you would all like to know why so many Lithium-ion battery units have recently been delivered to the Hornsdale Power Reserve in South Australia.

I know that I would like to know why.

Lindon for as long as I have been on this board it has been pretty clear that you post according to which way the wind is blowing, you are an obvious swing trader that should now be ignored.

that Bloomberg New Energy Finance reference :- https://about.bnef.com/blog/energy-storage-investments-boom-battery-costs-halve-next-decade/

Tom - BloombergNEF estimate roughly 300 GW of energy storage rolled out by 2030. Let's call that 30 GW per year. Let's be unrealistically conservative and assume only 2 hour average duration times for these batteries. That's 60 GWh per year.

Let's again be conservative and assume that VRFBs only take 20% of this (I think it will be 50% after 5 years) - that equates to 12 GWh per year for VRFBs, at 5,000 tonnes VANADIUM per GWh that works out at 60,000 tpaV.

Exactly Ophidian. Plus those electrolytes are inflammable. Can you guess which company is keenest to see this research funded ? Answer it's Royal and Dutch and it make fossil fuels. Can you guess why.

Pdub - I remember you also telling me just how good the Viljoen brothers were. On that basis I went out and bought one of their books, "Africa's top geological sites" which contains the following acknowledgement:

'Bushveld Minerals and VM investments have provided extensive logistical support for the project. Much appreciation goes to Fortune Mojapelo and Anthony Viljoen, the principals and executives of VM investments and Bushveld Minerals respectively, for freeing up various staff members to spend many hours, weeks and months in order to ensure a top-quality final product."

I wonder how many more of Africa's top geological sites Fortune and Bushveld Minerals will be associated with in the years ahead.

knuttie - and Adam Whitehead who was head of research at Gildemeister/Cellcube/Enerox before the first sell off 18-24 months ago when he went to redT

I had not seen that Paludina and Loudspeaker - thanks for bringing it to our attention

an even quicker search of the european patent office reveals at least two patents filed by Enerox, going back to february 2016.

sharesaplenty are you deliberately misleading or just incompetent ?

Following this article:- https://t.co/1TPcwfmOeJ?amp=1 and this video:- https://www.youtube.com/watch?v=SrFkZPrsik4 the question has arisen as to whether the Hornsdale battery is being increased in size or the battery units are simply being replaced, less than 2 years after they were first switched on.

Read this and then you decide :- https://twitter.com/BMNperspective/status/1195702781040119808

Yes Vauxhall Viva and only 56% of that number is actually Vanadium.

exactly right Delboys, this is a common mistake.

VauxhhallViva, Dalian will only take 4,000 tonnes of Vanadium

loudspeaker - I believe that the first time that the improvements to the chinese regulations was mentioned in public was at the Vanitec meeting in manchester in June 2017.

It was in July that the Vanadium price first started moving up - https://www.thebushveldperspective.com/blog/public-articles-1/post/july-2017-vanadium-shock-what-and-why-203

I don't think this was a coincidence .

For completeness here is that reference on explosion limits

https://www.engineeringtoolbox.com/explosive-concentration-limits-d_423.html

Apologies the level at which humans can smell ammonia is 0.04 PPM so a factor of 25 times lower than I previously stated - so roughly a level 4 million times lower than the explosive limit for ammonia.

http://www.ccac.ca/Documents/Standards/Ammonia.pdf

With respect to Ammonia - the issue of NOx emissions was of course the first question that I asked Siemens at the recent UK energy Storage meeting in Newcastle. He pointed out that there is plenty of Nitrogen in a normal combustion engine due to the fact that for each molecule of Oxygen you draw into the combustion chamber you draw in 3 of Nitrogen.

It turns out however that the lower combustion temperatures of an ammonia combustion engine means that there is actually less chance of producing NOx emissions than in a normal Carbon burning combustion engine.

Furthermore the fact that ammonia is a gas that can be easily smelt, just like natural gas once you've added mercaptan, means that you can track leaks very easily, which is very much unlike hydrogen, which is odourless and only needs to reach a level of 4% in the air to produce an explosive mixture. For Ammonia the explosive limit is 15% and human can notice the smell of ammonia at levels of less than 1/150,000 th of this (1 part per million).

Bella - the Vanitec Energy Storage Committee, under Mikhail, has been working on precisely this issue since 2017 as you can see here:-

https://www.thebushveldperspective.com/blog/public-articles-1/post/vanitec-3rd-energy-storage-meeting-part-3-173

and https://www.thebushveldperspective.com/blog/public-articles-1/post/vanitec-4th-energy-storage-meeting-part-2-275

The end conclusion was (in my words) " a single name had to be chosen to describe the single thing we are all trying to bring to the world, and this name is 'VRFB'. Vanitec cannot impose this on any other organisation who in principle they can carry on using what their own pet name might happen to be, but as far as Vanitec is concerned from now on they are going to use the term 'VRFB'. To be honest, from now on so should anyone else who is keen to encourage this industry."

maxwell - their content is shown here:- http://vanitec.org/vanadium/VRFB - this is produced by Lifa communications in collaboration between the VRFB manufacturing community and the chairman of the Vanitec Energy Storage Committee, one Mikhail Nikomarov.

There are plans in development to increase the cross-industry marketing of VRFBs.
