Historically, UPS units were very expensive and were most likely to be used on expensive computer systems and in areas where the power supply is interrupted frequently. For valuable information on why you should protect you equipment with an UPS: http://www.batterybackupguide.com/ups-battery-backup.htm

how do they keep the batteries at 300 degrees C. this is a tremendous amount of energy, isn't it?

stolennomenclature

It will require a significant amount of energy to initially raise the cells to 300 degrees, but since they are well insulated, it requires very little to keep them at that temperature. In fact the energy wasted during the charge discharge cycles (owing to the cells not being 100% efficient) is enough to maintain them at that temperature.

Charles R. Toca

Regarding efficiency of 89%, I assume this does not include efficiency losses of inverter. Assuming 15 - 20 % losses in AC to DC and back, would total round trip efficiency be closer to 69% - 74%?

Also, I've read that NGK system can cycle 2,500 and also 4,000. Which is correct, and what happens to system at maximum cycles?

Vanadium Redox batteris are also used for high level of energy storage. Out of these two,which battery system is more efficir=ent and cost effective

I have a concept idea whereby individuals with a minimum investment to pay for the costs of this mobile generator to generate, store and will be able use or sell excess electricity to National Grids.This will result in significant reductions of fossil fuel dependency. The idea has merit is workable and will make any country to be less fossil fuel dependent.The idea is already in the hands of an American Investment company who have expressed more than a passing interest in it.I am a student with a mind full of ideas on how to improve the lives of many suffering under the burden of high fossil fuel costs. I am hoping that with the help of this American Investment Company the yoke of bondage caused by high fossil fuel costs will be broken. Errol Smythe

America is sucking hind tit on the energy front. Why? check out all of the independent developers of technology that is available now. they're dead!

Can you confirm that the Sodium Sulphur battery was first conceived and researched at the Electricity Council Research Centre, Capenhurst, Nr Chester,UK in the early 70s

Hello,
I was wondering why the electrodes have to be in molten estate. Is it to facilitate ion's movement, or is it imposed by thermodinamical constraints ?(chemical reactions efficiency dependant on operating temperature leads to 300ºC op. temp)
Thanks

the new company combinding technology to take you off the grid is based in new york longIsland I think they go by the name Energenics systems i saw them at a LIFT meting

Shane Thatcher

Hi, I was wondering if anyone has an idea of what the cost (USD) per MW installed capacity is of these batteries and how long they take to charge once fully exhausted?

Thanks

Anyone know why there is only one company produce Nas battery?

snotty

We of The United States of America don't lead anymore We follow at a very safe distance, or just get out of the way.
Oh, and wait til a profit is assured to an international conglomerate (big and getting bigger entities) are in total control.

I have read a lot about this on other articles written by other people, but I must admit that you is the best.

But to the point: it is my belief that most women are inherently
somewhat more suspicious and less trusting than are most men.

I know to a near certainty that if I were to go over to my husband and
say "Oh, sweetie," and smile, he would think to himself "She loves
me!"

Battery power had increased over the last few years but it is still something that holds us back. I expect there will be advances made through necessity.

The writeup on the 4MW sodium sulfur battery at Presidio, Texas says that the main obstacle for installation was regulatory.

Poor edward has to do his work after dinner and he couldn’t go with us to play football. Because he dare not go against his mother’s orders. What a pity!

James, trying to contact you and my emails get bounced back as spam. Am writing article about the recent progress in NaS/NMC and would like to chat. Mike (editor, Batteries International)

I have question: Could sodium sulfide battery work for a railroad operation.

Mr. Roseland, that is a possiblity, like the Son the battery of the Father works just as well.PFC Roseland

Hi,
I was involved in NAS battery developement at ABB in Germany. In the early 90ties there was a joint venture with NGK called Nastech. ABB focused on NAS batteries for cars and NGK on load levelling.ABB stopped it's NAS business in 95, NGK proceeded. RWE - a German power supplier run a facility in Runcorn (UK) for NAS batteries named "Silent Power". They stopped business around 96.
To date NGK is the only company capable of manufacturing large scale NaS batteries.
I am still quite convinced of this type of battery - it is low maintanance, high power and long running without a tremendous loss of capacity over lifetime. The principles are easy to understand but it took lots of efforts - 20 years- to build up a mass production. The devil is in the details.
Not easy to copy!

Dave

Is it possible for an NAS battery to be produced that will be applicable to residential use as a back-up system for Solar or Wind generated Energy?
We presently are looking at about 20 1000c.amp. 12v batteries to provide about 48 hours of back-up for a Solar application (obviously not all Peak usage but then wouldn't expect it to be).
This of course is not really very acceptable to the typical consumer as most folks simply want a maintenance free/trouble free system for their power resource, even if it meant no more electric bill (or at least very low ones).
What we really need is a consumer care free back-up system that is 1) affordable 2) Maintenance free 3) very long lasting 4) quick to re-cycle with a charge 5) actually will make the Solar application the co-gen partner and not the primary Energy source; and I suspect there are a number of things I'm not thinking about right now but any thoughts or suggestions form any of you would be very much appreciated.
Kind Regards,
Dave
