>Grid-scale storage is purely theoretical today bar pumped-up hydro, which is infeasible in most locations

Viable locations arent in short supply at all:

They aren't in short supply, but aren't present everywhere - e.g. in Europe there's nothing north of Slovakia. If Denmark wants storage, they have to work with other countries and rely on transit. It's even worse for the Baltics.

You make it sound like it's some burden while the EU grid is actually a single market with a significant expansion last year: https://www.tennet.eu/our-grid/international-connections/nor...

Norway, UK and Ireland aren't in Europe?

Edit: I was a bit puzzled as there are already pumped-storage plants in Wales and Scotland with more planned.

Well, that also applies if Denmark wants uranium, oil or gas.

You know that you can just pump all the water Denmark has. Build underground caverns full with air, let water in for energy and pump it out later.
