thank you for the advice pierre, but quite happy being myself....

[pierre oreilly] 25/5/2017 11:16

Dig, i don't intend to get into any sort of chat with you - i've tried that before.

But please, just try to post a little more like an adult and i'm sure some info you bring will make much better reading which is much better for all concerned.

Pierre yes lithium does have its place and will do for many years to come but there are roles just not suited to lithium, there are safty concerns with placing lithium battery,s within buildings, there is the degradation factor to take into account and the cost of decommisioning, which is not factored into the buying cost...something an investor will look at.. while a redundent REDT battery will have a 30% residual value.

Well tonsil, there's power delivery (e.g. MW) and energy density (MWh).

So lithium has enormous power density. That's why i can start my 3 litre with a small handheld lithium power pack, a few cells wired together delivers very high currents, even at 12v (i think each cell is 3.6v or something). But for decent energy storage (like Musk needs) you have to wire thousands together at great cost. If you just want energy storage without the phenominal power delievery rates, then flow batteries do that much cheaper. Having said that, flow batteries can deliver decent power, sufficient for grid applications (although higher power is always welcome). Once red has a lithium front end, then they get bother extremely high power delivery (until the lithium is depleted) togather with cheap mass storage, which can re charge the lithoium front end ready for another high power delivery episode. Heat is also a bit of a problem with thousands or tens of thousands of lithium batteris wired together, which is why they aren't as good as flow for grid applications, at that level for a zero/low maintenance storgae system at grid level, flow batteries are better and cheaper imv. Musk is hitting the sensible limits of lithium in his cars imv. (and red aren't looking to put a container sized storage machine in a car, contrary to the impression sometimes given on here). The grid application of flow batteries is virtually infinite worldwide (well not infinite, but sensible to view it as such for our purposes - we don't have to get every order going!) for grid stability and instant frequency support applications, which generates massive payments from national grid. Being aim, this is a risk (as all aim companies are), but i have a lot invested here because there are just so many factors on its side, so the odds are in our favour as i assess it.

seems like I may have to crank up my posting, a few falling behind!!!

[dlg3] 25/5/2017 11:04

do you want me to do all the work for you??

[dlg3] 25/5/2017 11:03

This study has been elaborated (in cooperation with Camco Clean Energy Tanzania Ltd.) on behalf of
the Sierra Leone Ministry of Energy to develop the preparatory phase of a household energy plan.
This project has been financed under the Africa-EU Renewable Energy Cooperation Program (RECP,
www.africa-eu-renewables.org), an integral part of the Africa-EU Energy Partnership (AEEP).

Some on here so quick to pull apart a post without knowing what it is about....do some research..

[dlg3] 25/5/2017 10:59

Do you remember them now??? part of REDT!!! penny dropping..

[dlg3] 25/5/2017 10:58

I never said it had anything to do with battery storage, but it has something to do with Camco.. you mentioned battery storage not me!!!!

[dlg3] 25/5/2017 10:55

Pierre Oreilly perhaps you should use a few more cells before posting, you remember a company called Camco, part of REDT???? dig a little further....

[tonsil] 25/5/2017 10:24

PierreGood reading. One concern I have which is maybe misplaced, is the relatively low density of red. Lithium is high density with Mw per container. Red has many advantages but is Kw per container. It is an impression I would like to put numbers on to understand the additional space requirements. Any ideas?

[pierre oreilly] 25/5/2017 09:20

Dig, you confuse people. Sierra Leone is fa to do with battery storage, let alone red. There'll be no batteries there for yonks. Batteries are for well developed grids with sometimes excess capacity - a huge market for storage.

Everyone can see the success of lithium batteries. They are ubiquitous now. They have changed many products for the better. They have only a small overlap of application with red's stuff. They have succeeded and are excellent batteries, it's just plain stupid to try to slag them off all the time. In fact, one development area of red's is a hybrid litium/flow battery, which will put red well in advance of others, having massive power delivery (that's the lithum front end) together with massive storage potential (that's the flow bit), and red will then expand their application well into lithium dominated applications.

There are so many good things to say about red, but you simply miss the point most of the time, rambling on about stuff which is nothing to do with red, or slagging another successful technology which you seem to think massively competes with flow batteries (but doesn't).

PUG a few things to consider there, the cost of disposal, you would have this to do 3 times, Inflation, a battery costing £50,000 today may cost £70,000 in 8 years time,plus in 16 years time the same battery could well cost £100,000, so cost a big factor. There is also the fire risk...so the insurance cost will be more..so although lithium may be cheaper by the Kw, long term it can be very expensive..

Sierra Leone has mobilized $ 12.6 million for the construction of a solar PV power plant with a 6 MW capacity. The infrastructure will be located in the town of Newton, according to a statement from the Ministry of Energy.

Construction will be carried out by Infinity E-Construction which will also provide the various equipment. The energy generated by the plant will be used to increase the amount of energy available to the capital.

The project is co-financed by the government of Sierra Leone and the Abu Dhabi Development Fund.

The project is part of Sierra Leone’s Energy Revolution initiative, with the objective of increasing the country's energy capacity.

Sierra Leone currently has an installed capacity of less than 100 MW for an electrification rate of 13%. It intends to increase it to 100%, by 2025.

dig3: re your 1189 (imo) Could well include lithium as specification refers to BMS so if contractor believes price of lithium batteries likely to reduce and they are responsible quotation could well factor in costs associated with replacing batteries say 3 times during contract. Just depends exact terminology and offer price.

[alchemy] 24/5/2017 17:20

Some may have just deserted his MM post.''Tis not of moment.

[cheek212] 24/5/2017 17:02

Why has the spread changed after the market has closed? And why such a big spread? Not usually a whole penny - it wasn't that big when I looked earlier just after the market closed.

[fieldhouse] 24/5/2017 16:50

Sure does dlg3

[dlg3] 24/5/2017 09:02

NOTE THE 25 YEAR DURATION, THAT CUTS OUT LITHIUM AND SOME OTHERS....

[dlg3] 24/5/2017 09:01

The winning project needs to be a 6MW / 24MWh installation, operating at 33kV output for a 25-year lifetime. It needs to be a complete system solution, including SCADA (supervisory control and data acquisition) and battery management system (BMS). The awarded project developer or EPC would also be responsible for operations and maintenance (O&M) over the 25 years as part of the contract.

[dogrunner11] 24/5/2017 09:00

Actually on that NG tender isn't there a winner still to announce its technology?

[dlg3] 24/5/2017 08:59

India’s biggest utility, NTPC (National Thermal Power Corporation) is seeking bidders to add a 6MW / 24MWh battery energy storage system (BESS) to a 17MW PV plant in Manglutan, South Andaman.
Indian home minister Rajnath Singh laid the foundation stone for the PV project in early April. Our sister site PV Tech reported at the time that there would also be a separately held tender for energy storage to support the solar farm, which is located on the remote Andaman Islands, several hundred kilometres off the Eastern coast of mainland India.
