Hey Parkside what is your company called, its a better investment than IGAS for sure.

No I said crappy coal not crappy gas! CCGTs are good, efficient and clean enough for the moment. That's why the gov should build more not waste money on nukes or at least French ones! 5% of cars is a lot. I have the calculation somewhere but it's a huge number. Over 1m maybe which is a lot of storage. Hopefully we aren't burning gb's but yes 25GW is roughly half peak demand. It'll take years but I'm sure we will get there. I've just bought a hybrid and I'm addicted. It'll do 16 odd miles in electric only and I'm utterly sold.

Yes, using electric car batteries as back-up storage is a trendy idea at the moment, as is the idea of a more decentralised grid. But at the moment of course there arn't many electric cars. Time will tell how practical it is. Not sure what the difference is between "flexible" gas and "crappy" gas is. You suggest the relatively small number of electric cars can store 25gb, that is nearly half of the UK's peak demand - good luck with that.

Not really sticking plaster. It's been around forever but the new grid won't be centralised coal, gas nukes it'll be renewables with storage at distribution level, flexible gas and some nukes. So it'll move from a few crappy old coal, gas and nukes with a huge reserve (and massive centralised risk and balancing costs) to hundreds of thousands, millions even of tiny power stations - solar, wind, ad, biomass etc - some bigger legacy plant and lots of batteries in the form of cars. Nissan are trialling it now. 5% of electric cars in the UK can do 25GW of storage and smart meters will do the rest. Lower power prices and the end of centralised power stations with huge power losses to get the energy to where it's needed.

It's a vanadium redox (flow) battery each 1MW and so can deliver 1MW for 1 hour or 0.5MW for 2 Hours etc. Can't tell you cost as its a secret but it's lots per MW!! Typical lithium ion batteries on MW scale might be say £1m/MW or thereabouts with ten year life.

Doesn't surprise me that this is a realistic business project because fast response and STOR tariffs are many multiples of normal rates so basically IMO your company's work doesn't really tell us much about the viability of battery technology for normal electricity supply. Actually the STOR market has become so popular because of the possibility of shortages has made essentially "sticking plaster" supply so lucrative.

To measure a storage device you have to measure it over time, not just in MW. So is that a mega watt/hour? The battery on my van will give me a hundred ampere /hour.at 12 volts thats 1.2 kW/hour. It cost £80. What will your battery cost and what will its life span be

Nope it's accelerated incredibly and we are installing three 1MW batteries on a project to play the fast response and frequency response mkts. Maybe STOR a bit too although we don't really have the duration for that piece. In a recent presentation, WPD had had 8GW of applications for storage. Now nowhere near that will be built but it shows the interest. Once you fit storage to renewables (unsubsidised) then that's a game changer.

About time too that there was storage capacity for wind energy, otherwise it wastes excess generation on windy days, and fails to compensate for when the wind drops. Another way to store wind energy is to use excess power, especially at night, to pump water into holding areas, to be released as hydro- electric power, when needed. Hydro electric power has the ability to come on stream and start generating within a few seconds of the gates being opened. The silliest thing however, seem to build wind generators but fail to recognise that they are also standing in tidal energy . Like rotors could have been built underwater as an extension of the same plylon which supports the wind generator above. Tidal energy is twice per day in each direction. Only a small fraction of the time is slack at high and low tide, when the water is almost still. But, given that the tides are at different times around the coast, then one can say there is always water energy available all of the time

Good luck with your project especially if, as you say, the battery power is not subsidised by other bill payers. I'm only an amateur but from what I read most large-scale battery projects are heavily subsidised trial projects in the UK. I think there's one in Northern Ireland that is 100mw and that is still in the construction phase. I'd be pleased to be proved wrong. There is of course the Tesla Powerwall which stores about 7kw/hrs (an old style one bar electric fire for 7 hours). Have I got that right? With the dc/ac converter and installation they cost about the same as a small car. Regarding upscaling BusinessGreen the renewables friendly website predicts 1.6 gw by 2020, so about 3.2% of maximum winter demand. In other words looks like another virtuous project appealing to the rich greens.
