"the problem is what to do when it gets dark"

Batteries (or pumped storage hydro, which is more like a gravity-driven capacitor)

Hungary is flat as hell, there's nowhere to build enough hydro storage.

But yeah batteries would be nice.

		AFAIK the mountains are about as high as Wales? It looks like there's a 600MW storage scheme in the planning stages. That's about a third of the capacity of Wales's largest system (which is the biggest in Europe) and about twice the capacity of the second system. It's a meaningful contribution I would have thought.
