What kind of energy density could we get using it for energy storage?

Maybe it’s competitive with batteries if you don’t need any cooling?

Like 1-10 wh/kg from what I've seen. Probably better off building a ring around the planet so we can just always have solar panels lit up somewhere.

I wonder if that low number includes all the cooling equipment though?

But even if not it could be great for a capacitor alternative or stationary storage.

Superconductors are a transferring energy technology, not a storing energy technology. Although they would likely augment the efficiency of storage technologies.

Actually both https://en.m.wikipedia.org/wiki/Superconducting_magnetic_ene...

They can be used to store energy, though they're pretty terrible at it for all but specialized applications.

Actually, not a lot. The are some very compelling uses of them for storing energy, but they are much more relevant for distribution grid stability and control than for raw energy storage.

There are people here are pushing some really non-compelling use cases (like long distance power distribution), but there are plenty of transformative ones.

(But the thing is that this one on the paper is much less useful than it could be. There is still some work on understanding why and fixing it.)
