O/T:- Heatwave weather [Re. Climate Opinions/Handbags]

The best grid-scale storage to date is pumped hydro. Can be build very large scale. Generally that'd be my preference.

Like Dinorwig you mean? Nearly 40yrs on and the only one in the UK. Someone (on another site) estimated that if the reservoir was the size of the whole of Wales it could possibly supply the UK with 6hrs of electricity. God only knows how long it would take to then replenish itself. Don't forget it also need a lower reservoir as well as the upper reservoir.

The Chinese seem to be building them at a fast rate but then they don't have to worry so much about planning permissions, space, mountains and the environmental impact.

Where would you build a very large scale unit in the UK? And what do you consider "large"?

Don't know about the UK. Where I live in Australia, the grid I'm on is connected with every east coast state and SA, stretching thousands of kilometers. A recent study done identified a mere 22,000 or so possible large scale pumped hydro storage sites. Perhaps the solution for the UK is connections to Europe and storage there if you can't find a single suitable site on your hilariously tiny island.

Ah Australia, well lots of space there, lots of sunshine. All of the UK is interconnected with the National Grid and has been for as long as I remember.

We have lots of interconnections with our neighbours, current and planned:

https://publications.parliament.uk/p.../121/12109.htm



and we can see exactly where our main power is coming from or at times being exported to:

https://www.gridwatch.templar.co.uk/

So at the moment I'm typing this we are exporting 3GW across the 4GW interconnector with France. Fortunately there is nothing connected to Russia or Ukraine.

When are you going to let WA join your interconnects? I don't know why they don't declare UDI.

WA is so far away nobody's seriously considered connecting them up. NT in a similar boat except they're so tiny it isn't worth it for that reason. But in both cases they're working on their own storage for their grids.

But it's all doable. We'll have completely fossil-fuel-free power in the coming decades.

Where abouts do you live? SA doesn't have enough of its own energy to keep the lights on and has to steal it off everyone else is it really giving energy to other states?

Yes. When it's windy SA routinely pumps half a gigawatt over the border. Aside from Taswegiland (lots of Hydro) they have the lowest emissions of any grid.
