Anyone know anything about these new "battery barns" that the subsidy
farming companies are trying to set up? The idea is to charge them from
the grid at certain times and then release it back when needed. There's
a planning application for one near our village. It's huge - about fifty
Just pray no one ever puts a short across it
I would oppose it like the blazes on the grounds of safety and
Find out its storage capacity and express that in tonnes of TNT and ask
the council if they feel happy granting permission to such a hazard.
Future generations will wonder in bemused amazement that the early
twenty-first century’s developed world went into hysterical panic over a

The reason we use petrol and diesel is because they are a reasonable
compromise between easy to get the energy out of and safe to store.
Batteries are not so safe to store.
They contain the means to self ignite

I was going to say something similar but you beat me to it. The
equivalent hazard to battery storage is not, as Harry suggests, petrol
in a tank, large or small, but storing the fuel for LPG vehicles as a
compressed mixture of gas and air, or gas and oxygen.
I would say the major difference which includes LPG tanks is there a
physical separation between the two elements, fuel and air/oxygen. In
some instances there are some statutory requirements.
The saving grace for batteries is that cells are generally designed in
such a way where if one lets go, it will have limited effect on
surrounding cells. If you don't:
Someone phoned me today to try and get me to fit a solar battery and panels.
They decided to hang up when I asked them how many hundreds of panels I
would need to charge the battery and supply all my electricity even in
I think its about 10 sq meters per kwhr in winter and about 20% of that
How many kwh do you get from your two 4kwp arrays in winter?

Well if you have PV and batteries, so you can.
I did think about it myself but the prices are stupid.
Mind you, it would be a straightforward DIY project.
Depending if you wanted to get 220Vac from the batteries.
12Vdc/220vac inverters are easliy available.
Or just have lighting and 12v LEDs.
My cousin has PV panels that were supplied and fitted to him free, he
gets the electricity (free from the panels) but has bought 4 x battery
himself (probably ~£4k).
I asked him how long he expected to take him before he saw any real
savings and he didn't know. ;-(
I'm pretty sure he didn't know who paid the company supplying the
'Free' panels the FIT cash and think he might not have gone ahead with
it all if he had.
Given his age and the fact he has no offspring to leave the house / PV
system to I'm guessing he just has some spare cash to play with (and I
can understand it (the battery part) for those reasons). ;-)

Any info in the PA about capacity, MWh, how long it'll supply the grid
for, flat out, that sort of thing, bearing in mind that the UK
consumes something in the region of 800-900GWh of electrical energy
per day? I'm not suggesting this one will have anything like that
capacity, it won't come remotely near it, but I'm passingly
interested. The pumped storage facility at Dinorwig can supply
approximately 1.7GW for six hours.
No more than say 100 tonnes of TNT stored in as shed.
All googling reveals is PR and marketing lies.
It seems likely that a typical barn might be 10MW with a capacity of
around 50MWh. Lithium batteries in racks. The ones that you are not
allowed to take on planes because they catch fire.
At a guess lithium batteries at that scale would be around £500/Kwh, so
this size of barn would represent £5m or so.
I reckon a Dinorwig would cost about a billion these days for 10GWh. Far
cheaper and lasts longer.
Which is about the same energy as 43 tonnes of TNT. Which would be
released if they got shorted. Internally. Accidentally.
But this is a guess and no one is actually quoting real numbers.
Of course they will sail through planning just like bird mincers and bat
exploders do, and the only class of rotating industrial machinery apart
from aircraft propellers that is allowed to be operated without a safety
Sigh. The whole point of brexit was to ditch this renewable shit and
build gas power stations and nukes.
