Isn't pumped hydro severely limited by geography in many places?
I'm hoping for some other technology apart from pumped hydro or batteries to be used for capturing surplus renewable energy for later use. It's unfortunate that hydrogen seems to be too complex to handle at these scales, it'd be utopian if it wasn't and the excess of renewables could be transformed into hydrogen for use in turbines instead of nat gas...

Scotland seems to be a perfect place for pumped storage. I see that UK has 4 pumped storage stations, 2 in Wales, 2 in Scotland. But Scotland being quite far from most of UK's population may not be ideal if we're talking about supporting the whole country with pumped storage. It would be like 600km to the south of England.
HVDC would work quite well for a 600km transmission line, I don't think it needs UHVDC lines for that kind of distance.
There are several lined up for construction over the next 5-10yrs (eastern green link 1-5)
Yeah, the idea of people claiming that something on the Great Britain is too far and can't distribute power to something else on the Great Britain is laughable.
Next we'll have somebody from Lichtenstein saying the same about their country...
Why 600km exactly?

Iron air batteries sound promising
exactly, and they are cheap, right?
Pumped hydro needs a hill to pump up. That's why I said storage and transmission. We are laughably bad at moving power from where it is made (or stored) to where it is used and the worst part is it's not even a problem of science or engineering. We have it all figured out!
It's purely a problem of political will.
