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...
- oskarkk 7mo ago> Isn't pumped hydro severely limited by geography in many places? 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.
- piva00 7mo agoHVDC would work quite well for a 600km transmission line, I don't think it needs UHVDC lines for that kind of distance.
- functional_dev 7mo agoWhy 600km exactly?
- oskarkk 7mo ago600km is roughly the distance from the hilly parts of Scotland to the south of England.
- marcosdumay 7mo agoYeah, 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...
- oskarkk 7mo agoWell, I only said that if we're considering a ~fully renewable energy generation in the UK, with supply evened out by massive pumped storage projects, then locating all the storage in Scotland isn't ideal for the efficiency of the system. But yeah, I looked up the losses on HVDC lines, and it seems to be a non-issue (at least from a technical point of view). I also looked at a map of wind power[0] - seems concentrated on Scotland, so the distance from generation to potential storage would be quite short.

- gehsty 7mo agoThere are several lined up for construction over the next 5-10yrs (eastern green link 1-5)
- jonatron 7mo agoIron air batteries sound promising
- functional_dev 7mo agoexactly, and they are cheap, right?
- idiotsecant 7mo agoPumped 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.
