Default [Power] "Next generation utility wins contract for UK's biggest battery"

Maybe its cheaper just to flood old mines and use turbines to generate power
then pump them out when there is little demand. Is it any less efficient
than a bleedin big battery which needs to then be converted to AC in any
case?

One can't help wondering how many of these battery banks are needed to
actually make a significant contribution to the grid. 6MW, 10MWh, so
6MW for ~90 minutes supply before it's flat, as they point out.
Assuming an average UK daily consumption of 35GW, i.e 840,000MWh, we'd
need 84,000 of these battery banks to keep us going for a day, if we
were relying entirely on wind and sunshine and TWDB&TSDS etc. I doubt
it's realistic to think that wind and sun would ever be the only
sources of supply, but it does suggest we'd need a helluvalot of
batteries to be really useful.

Flood them with what?


Water?

I would not think the water capacity of a disused mine would be enough
to make it worth while.

Of course it isn't., But you are supposed to applaud the IDEA and the

Tim Streater brought next idea :
Which you get from where? And when it comes to pumping it out, where
does the water go?


It would be pumped out to a lagoon, then allowed to flow back via the
generators.

A lagoon eh? And just how big would this lagoon be and where do you
suggest it is located?

Until there is a quantum leap forward in battery technology, which may
actually be theoretically impossible, then this is a complete waste of
time. Stop scratching the surface and build nukes before it is too late.

I was just explaining how it would have to work, I had already said it
wasn't workable due to insufficient capacity to make it a worthwhile
venture.

The argument goes that, since PE=mgh, you can get away with less m by having
a bigger h. If the mine is 2km down, you can use 10x less water than pumped
storage where you might only get 200m.

Unfortunately, the problem is that mines contain corrosive things and all
those nice support structures that are keeping the mine open may not stay up
for long with all this corrosive water sloshing about.

Something liquid at room temperature and quite dense would be preferable.
Mercury would appear an optimum choice. As for finding an old mine with a
shaft still usable and with roadways still inctact then you are ****ed before
you even start.

The one they're talking about in Germany is still a working coal mine,
but due for closure next year. As to whether an old long-closed mine
can be reinstated would depend very much on the type of mine and the
geology of the site. Coal mines would be near impossible I would
think, but many tin and copper mines in Devon and Cornwall have been
re-opened in the past and even relatively recently after decades of
being closed.

It takes around 4-6 years to pump old mines dry before they can be reopened.

lifetime of seawater pumps and turbines is not great.

And if they bitch about fracking clean water plus a teensy bit of
antibacterial into the ground, what would they think about dumping
tonnes of seawater into the aquifers.

Oh. Of course. Greens dont think. They emote with their 'emotional
intelligence'

Ah, so you're suggesting pumping seawater into old coal mines. Does
that work for the ones that are miles from the sea? And can you
guarantee no leakage of seawater into local aquifers?

I floated my questions above in the expectation that some numpty would
be drawn to them like a moth to a burning fart, and sure enough ...

And we reply to it tongue in cheek in the expectation... you know the
rest.
