Yet :-(. Lol

No rns today :-(. Lol

Interesting to see that VSA Capital target of 22p as I first paid 23p for a bunch of these in the early Camco Clean Energy days. Not a great buy as the share price fell steadily from that point, but I was able to average out my cost over several years to its current 4.3p level while CCE was busy transforming itself from a Carbon trader to a battery designer/producer. I could have sold for a healthy profit several times in that period, but in the last couple of weeks the decision to hold on seems to have been vindicated and I now believe that 22/23p level will seem cheap in the not too distant future. So I'm with you, netcurtains, holding on for 50p!

[ianous] 25/9/2017 16:24

Market cap pre placing was circa £80m (500m chares at 16p) so an equivalent M/C with 650m shares = 12.3p

[netcurtains] 25/9/2017 16:14

Looking good for 50p (over 12 months - best guess - small rise on every new order with slight pull back after each one - more or less constant rise to 50p - that is my vision - lets hope its something like that!!! 9 * out 10 I'm wrong)

[alchemy] 25/9/2017 16:05

The Marcap must be nearing where it was though - we had quite a fund raiser.Nevertheless ,yes, much de-risked etc.

[cheek212] 25/9/2017 15:30

MMs just widened the spread at pull down the share price - an old fashioned tree shake I think they call it. Not having any of mine!

[pierre oreilly] 25/9/2017 15:25

boad, i think (and hope!) red are just working on their mass market modular product, and not doing any bespoke one-offs as you suggest (which could possibly be something they'd do well into the future).

But a mass market containerised modular product means every order is similar, loadable onto a truck from wherever it's made and loadable onto a container ship for dispatch to anywhere. There are big benefits to standardisation.

[pierre oreilly] 25/9/2017 15:21

This still needs to rise 50% from here to get to its recent highs.

The offering today is at a far less risk and far more orders and a far better outlook than a few months ago when this was around 16p.

dlg3 - Yes, except I was thing of using the ready made tailings dam of a defunct gold/silver mine as cheaply available safe fluid storage.

[dlg3] 25/9/2017 14:31

If they can guarantee the tanks there should not be a problem...using vanadiun... the German tech uses salt and other chemicals, but is years away..

[dlg3] 25/9/2017 14:29

For the two initial test phases in the 10 kW to 500 kW range, instead of using actual caverns, enormous plastic containers will be set up at the EWE gas storage facility. These earlier phases are expected to start in the fourth quarter of this year.

[dlg3] 25/9/2017 14:21

boadicea YOU MEAN LIKE THIS !!!

A German gas storage firm is planning a battery big enough to power a city the size of Berlin for an hour, using redox flow technology.

The planned project, which Oldenburg-based EWE Gasspeicher is billing as the world’s largest battery, will involve filling two salt caverns, each of around 100,000 cubic meters in volume, with brine to create a redox flow battery that has capacity of up to 120 megawatts and 700 megawatt-hours.

Boadicea.
I will try and answer your question with what past knowlage I have of Electronics.
(I used to be an electronics engineer, now retired for the past 15 years).
Think of REDT,s Flow Machines as big battries, You can connect as many of them in paralell to increase the output in Mega Watts. If you connect capacitors or battries in series then you increase the voltage. Ie, 12 Volt +12 Volts in series would give you 24 Volts with no wattage increase.12 Volts+12 Volts in paralell would give you 12 Volts with bouble the wattage.to put it simply.(Internal ressistance does come into it).
So in a nut shell there is no limit to how many REDT machines you can connect in paralell to get the required wattage.AIMHO. Stand to be corrected.

Billion dollar say for convenience £650,000,000 ...surprise a £ per share.

[dogrunner11] 25/9/2017 13:27

There was talk or investigations into putting the tanks under buildings not so long back, think John Ward did some presentations on that.

Thing is for now we have such a large market to attach, worth many billions, that we really don’t need a distraction like that and I am pretty sure scott won’t take his eye of the ball.

Billion dollar red, coming soon.

[crystball] 25/9/2017 13:20

Good to see today's announcement.

[boadicea] 25/9/2017 13:18

Thank you, Pierre - that all makes sense.
What I was thinking about was the possibility of permanent storage tanks built along the lines of a reservoir. A particular application for storing secure cyanide contaminated water storage is the tailings tank of a gold mine. Would a disused/worked out mine be a suitable place to convert to a large flow battery system at minimum cost? (Assuming of course that it provided a usefully accessible and required source of electricity.) The necessary civil engineering expertise should already exist and redT would provide the reactor units. In the event of an accident, how would the leakage of some Vanadium pentoxide solution compare to cyanide in potential environmental harm?

[dogrunner11] 25/9/2017 13:10

Service at 10 years I thought I’d heard mentioned, but realistically refurb after 20/25 years it’s good to go for another 25 years or so. They could potentially go for 40 years but time will tell.

[pierre oreilly] 25/9/2017 12:35

The weakest link is the pumps. They need changing every few years, simple job, probably part of a service from a management contract red would sell along with the machine. The modular design means effectively there are no limits as to either power capacity or energy capacity. You need more power, buy some more units, need more energy storage, buy some more units. Pragmatically, at some stage you'd reach limiting factors, but for practical purposes that is unlimited.

(This unlimited modular design is an advantage over lithium for example, where the cooling requirements mean there's a limit to how many lithium cells can be packed together. And in places like Africa, the ambient heat makes the lithium systems even more poor in that respect). Although big lithium systems are being given away by Musk as a one off, it'll be interesting to see how reliable and robust that system is. Just a few cell failures from the millions he's wiring together will cause a performance drop, and as time goes on and more cells fail, the mtbf will be very low imv). Small scale storage is lithium domain mostly, large scale storage is flow battery domain, as is small scale in hot countries.

[chicken01] 25/9/2017 12:24

Boadacia...maybe you should email RedT and hear what they've got to say on your questions, sorry but I for one don't know the answers...

[boadicea] 25/9/2017 12:20

As a relative newcomer to redT I am interested in exploring the possibilities of their technology. I appreciate that the current products are designed on a convenient modular basis which is good for transportation and quick installation.
However, given the long potential life (20+ years) of the plant, there is no need to think of it as transitory or temporary. Incidentally, I suspect the life limitation is probably due to the reaction part of the system (?membranes, pumps, filters, electrodes??) rather than the life of the electrolyte.

Considered as a permanent system, what is the limitation on the size of the reservoir tank(s)? A larger reservoir would presumably give the choice of a longer power output at a given rate (limited by the reaction process) or a higher power given the addition of extra reaction capacity.
Have the economics, feasibility and perhaps safety of a large scale fixed installation been considered and does the knowledge base contributing to this thread know of any references to such.
