that looks very interesting bassguy

Faramog - yep almost definitely at least 7.9M short still held by TPEP (they might have reduced by 150K without having to notify the FCA, but not more)

Terrible news again. When will the mega-miners get their houses in order ?

Given what happened to Iron prices following the Vale dam disaster you would not need to be a genius to suggest that Cobalt prices are going to spike higher. The disappointing thing is that this might simply lead to more profit for Glencore.

This makes a lot of sense - from what I understand South Korea has in the last few years had something like 20 fires involving Lithium-ion battery installations. This has not been widely reported as they put a lid on this information because they were concerned about protecting their Lithium-ion battery industry.

Brad no that's just a regular rollover that appears at the end of the day, no doubt something to do with some spreadbet platform

Guys with respect you will just be wasting your effort spending time dreaming up marketing names for companies that you don't work for. The people already operating companies making VRFBs already have their own names for the batteries they make, Vanitec spent a long time trying to build consensus about how to refer to these in their promotional campaigns, conducting multiple working sessions on the topic (eg 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 ) concluding that the name that they would consistently use to describe the devices made by the people in the field would be 'Vanadium Redox Flow Batteries' or VRFB for short.

If you want to make a contribution to the consistent promotion of VRFBs then consistently calling them VRFBs is a good start.

Nice job Voltmeter I was chatting only last week with one of the heads of New Technology at Scottish Power and made sure that he was up to speed on developments in the VRFB space, as well as some of the more concerning recent safety issues with Li-based installations.

RK - I too went to the Fully Charged show and did find one person who knew what a flow battery was, they were on the circuit side of the building in the first hall you entered but I cannot find the guy's business card at this point. I also spent a good time talking to the vertical axis wind turbine guys.

However as you say most of the other guys there were coming from an eV perspective and there the only game in town is Lithium. Robert Llewelyn should know about flow batteries because he interviewed the guys from Redflow (Zinc-Bromide not Vanadium) flow batteries here:- https://www.youtube.com/watch?v=4OHstY_kKUY

Ophidian - we had the whole 'battery' debate at the 3rd Vanitec energy storage committee meeting around 2 years ago. The conclusion was that if it stores electrical energy in immediately accessible chemical energy form it is a battery and that the vanadium redox flow battery is an apt description. Batteries that can be recharged are a subset of these called 'rechargeable batteries'.

Trying to redefine things, as Scott McGregor of RedT, did as 'Energy Storage Machine' just makes things even more of a mouthful. Scott claimed his beef was about 'batteries' somehow being 'disposable' ignoring the fact that the lead-acid battery was invented 160 years ago. In the utility energy storage space the term 'battery' has become accepted whether we like it or not, so the debate is pretty much over now.

I'd say it has held up pretty darn well given that in less than 10 days Vaneck have sold something like 23 Million shares,

faramog - I think giving away free machines is a bit steep.

SoTRR - as I've pointed out before in connection with Concentrated Solar Power electricity generating plants if you want to extract electrical energy (or mechanical work) from a heat engine you need not just a source of heat but also of cold. You need these in relatively close proximity otherwise your machines become very large. The amount of electrical energy you can extract from a small temperature difference of, say 10 degrees is 10/300 where 300 is the absolute temperature - i.e. so maybe only 3%. If all you want to do is cool the air down then all you really need is a big heat exchanger which you pass lots of the thames through. If you actually want the air colder than the thames then you need to drive a heat engine in reverse, using electrical energy and dumping the heat out to warm the fishies.

there have been competitions running to cool the underground for more than 15 years

Gunnerbgood - if RedT goes down the pan it will be nothing to do with VRFB technology and everything to do with their way of going about the business of building and selling VRFBs.

You could say that their outright refusal to ever talk about the batteries they build as 'batteries' is one reason why they are not being considered as a competitor for 'battery storage'. Ditto their steadfast refusal to try and ignore the fact that VRFB's contain V in the face of many reasonable questions from commentators and investors.

I hope that under new management they will be a bit less fixated on some aspects of the promotion and more on the actual delivery. The complete disaster that happened with their Gigha project must not be allowed to be replayed.

No it will be the stone coal production at the high end of the cost curve.

Interestingly there was exactly the same trick tried at 9:08am yesterday morning with a trade at 25.95p when the real ask was 25.70p and below the bid-ask midpoint

designed to mislead - at 26.0p a few minutes ago - the ask is less than 25.75p so that they can pretend that real buys are actually sells. Surely they have figured out by now that we are not falling for this kind of nonsense any more.

Drifter - where have you got those figures from ?

Paludina - a good find, of course Vanadium is currently a lot easier to manipulate as there is no futures market and there is (currently) only limited sources of supply. Furthermore the supply that does exist is controlled by an even smaller number of players (one).

NickyP - this is the sort of thing that RedT should have been all over. Unfortunately I am not sure that they have been, are or will be.
