can a lithium battery do this????

Using flow batteries as layers in a 3D stack would provide both power and cooling at the same time. In a flow battery, an electrochemical reaction is used to produce electricity out of two liquid electrolytes, which are pumped to the battery cell from outside via a closed electrolyte loop.

Most of the advantages of this type of design seem to point towards grid-level load-leveling storage, since flow battery technologies provide very high power and very high capacity. Am I the only one thinking they’d work really well for EVs? Apparently not. From EVWorld: Flow Battery to Power QUANT e-Sportlimousine Concept.

…and a motorcycle already has a tank to hold liquids, right? You want more capacity, add a larger tank. Sounds familiar. Also, you can “recharge̶1; simply by replacing the electrolyte.

Lithium and Flow will have a future, hence we are looking at a hybrid.

Lithium is cheap on power we are cheap on energy, look at the Chinese tender, it's 100MW/5000MWh, lithium just couldn't do that as a flow battery can.

This is how the market will unfold overtime, certain projects suited to lithium some to flow battery and others will suit a hybrid solution.

Rome wasn't built in a day, apparently, although I would like to see what they achieved at Baiae looks quite interesting specially if you allowed to scuba dive.

does this mean lithium is now dead or is this company built on hype?

[dlg3] 17/4/2017 11:21

TOYOTA are looking into using flow battery,s for their cars, so I think some had beter brush up on their research !!!!

In order to demonstrate the vanadium battery in a mobile application, therefore, a 36 volt vanadium battery prototype was installed in a commercially available electric golf cart at UNSW in 1994 where it was subjected to over 2 ½ years of off-road testing (8). The photograph in Figure 7 shows the vanadium battery powered golf cart with the 5 kW battery stack mounted on the back and electrolyte tanks under the seat. This 5 kW stack is considerably oversized for this application and with suitable re-engineering a compact stack of one-quarter of the present size should be achievable.


To achieve a compact stack design, thinner flow-frame dimensions (3 mm compared with original 5 mm) were employed in a second prototype stack which was installed in the golf cart in early 1997.

Extensive off-road trials of this battery showed excellent performance over a range of terrains. With 40 litres of 1.85 M vanadium electrolyte per half-cell tank, a driving range of 17 km was obtained. The total driving range expected for 3 molar vanadium solutions and full tanks containing 60 litres each side, therefore, is around 40 km.

A new improved 3 M vanadium solution has been undergoing bench-testing since late 1997 and is currently being evaluated in the golf-cart battery. Preliminary results look very promising and if long-term testing prove to be successful, a practical 3 molar vanadium electrolyte with energy density of over 35 Wh/kg will be available for commercial application. Further research into air regeneration of the positive electrolyte, should double this to over 70 kW/kg (9).

While the present energy density is relatively low compared with new high energy density systems like the lithium, nickel-metal hydride and sodium nickel chloride batteries, a practical driving range of around 120 km would still be expected in an electric vehicle applications. In particular, the use of vanadium batteries in electric buses would allow 24 hour a day use of the buses if electrolyte refueling is employed every 4-5 hours during driver rest breaks

a million or two would go a long way for any project and therefore worth waiting for, I wonder, assuming they have applied, if we will get confirmation of this in accounts. It would certainly be welcomed if so. If they are accepted there's no reason why orders can't then flow may onwards as that will still mean we qualify for said funding IMO: -

Industry applicants or project teams, which must be industry-led, can apply for up to £1.0 million grant funding for industrial research projects and up to £2.5 million grant funding for experimental development projects. The maximum funding to be allocated to any single project is £2.5 million. Any project selected for funding in this Competition will be required to provide significant private sector funding alongside the grant funding provided by BEIS (further details of the match funding requirements are in section 5).

• Conditional grant offer letters issued (May/June 2017)
• Grant awards & projects start (June 2017)

[dogrunner11] 17/4/2017 10:45

I don't believe they have any problem with orders, they are gearing up to mass-produce and in that they need various customer support, installation engineers and engineers who can at anytime be called to various installation locations worldwide visit installation site for any maintenance work required.

We have also had software people as remote monitoring will be of paramount importance, all this takes a time to implement, recruitment does not mean you have all 30 staff in one month, they are built up slowly and trained.

Additionally I posted this a little while back:-

Here's my thoughts on why we might be due some funding and reasons why we have not yet had commercial sales. Take a careful read of funding that is due to be confirmed by May/June this year, there's a significant amount of money available that a project say the size of an 18MW wind farm would benefit hugely from, even one in Halifax part owned by E.On: -

1. The Energy Storage Cost Reduction Competition – Overview

The objective of the Energy Storage Cost Reduction Competition (the Competition) is to support, through capital grants provided by the Department for Business, Energy and Industrial Strategy (BEIS), a number of industrial research and experimental development projects aimed at securing cost reduction in larger-scale energy storage technologies.
The Competition will consider projects for cost reduction of thermal, electricity or power to gas storage technologies which have the potential to reduce overall energy system costs; enable increased deployment of low carbon generation technologies or secure cost- effective efficiency improvements in generation technologies (renewable or non- renewable). The focus will be on reducing the levelised (full-life) costs of energy storage and applicants will be required to justify the cost reduction they expect to secure through the proposed innovation project. The Competition will prioritise support to larger-scale storage technologies capable of operating efficiently and cost-effectively at 1MW export power or 1MWh storage capacity upwards.

The Competition will focus support on component or sub-system level development and testing or improvement of manufacturing processes, rather than full-scale system prototyping and operational demonstration. While the Competition will be open to all types of energy storage technology, funding will not be provided for technologies which are already widely or commercially deployed (in the UK or elsewhere). The supported storage technologies are expected to be at an advanced stage of demonstration or close to commercial deployment.

Robert the book worm,

Realise you are here to push another investment, however I will point out that what you have said regarding cars etc is not true, there's recent research for a flow battery to power computers, if they can do that they can make one for a car no-doubt at some stage.

"Researchers at ETH Zurich and IBM Research Zurich have built a tiny redox flow battery. This means that future computer chip stacks - in which individual chips are stacked like pancakes to save space and energy - could be supplied with electrical power and cooled at the same time by such integrated flow batteries. In a flow battery, an electrochemical reaction is used to produce electricity out of two liquid electrolytes, which are pumped to the battery cell from outside via a closed electrolyte loop."

Hence reason why redT are investing heavily in research today, they have filled various roles for R&D with chemical work and others who are working on a new membrane.

Pierre, I counter-propose BMR as the company with the oddest shareholders. The company has a mcap of about 12m, proven assets of over 1bn and around the same again unproven, but its shareholders do nothing but run their company down.

As for RedT, it is reasonable at this stage of company development to expect commercial orders. Their apparent absence is very worrying.

[pierre oreilly] 17/4/2017 09:21

I'm putting this company down as the one with the oddest shareholders. There are those, or one at least, who think posting endless irrelevant guff all day long attracts other investors (my view is it does the opposite). Then there are those who don't really understand the nature of aim companies. Aim is the risky end of investing. If companies were well established, had full order books, had worldwide customers, had a long history of paying dividends etc etc then it is unlikely to be on aim, and unlikely to have a tiny market cap. For those who want a full order book, then look at companies with a full order book and not those just at the point of commercialisation. The obvious advantage of aim companies without full orders is that they are cheap. You can invest cheaply and if they get orders and sell lots, then he price doubled, triples, goes up ten or twenty times. That's the point, you take more risk for the chance of gaining a lot, or worst case, losing the lot. I get the impression some hope for the impossible, to pump some cash into a company and immediately expect all the risks to disappear with an instantly filled order book.

I see this as about the best risk of all aim companies ( or at least those i looked at). It has all the qualities i look for, no one can question the market size, no one can question the tested product, i have faith in the competence of the boss so to me, the odds are in my favour. Give them time and there's a very high chance of plenty of orders, but at that time, you won't be able to buy in at 9p of course.

[vatnabrekk] 17/4/2017 08:48

We really need an update with more information from the company before we can answer that question.

[bookwormrobert] 17/4/2017 08:07

Two things: firstly, even the craziest supporter of vanadium flow redox batteries can't suggest that they are suitable for automobiles. Think of their weight! And, secondly, the key issue here is not whether the world is changing. It is. Rather, it is whether RedT Energy can sell and profit from THEIR battery technology. So far, this seems very questionable.

"gangs of foul-mouthed pond life" now that sound like someone else, any ideas jonny boy??

[dlg3] 16/4/2017 20:58

johnyo thanks for your input, as to your questions I would answer them yourself and do a little homework..... as for orders I care not if they come from private or public companies an order is an order.... well it always has been in my book..

[johnyo] 16/4/2017 18:50

Dig please get a life you sad little pond life mug, Yes we know battery storage is the future We need orders from private companies ! Are we competitive ?Is our product the best on the market ? These are the million dollar questions dig
