I'm afraid not, the magnetic field might be a bit too strong.
But for local/grid storage, it's perfect. Also, infinite magnets, this might allow for less neodymium in renewable. And probably dozen new applications we don't think of yet.
I said 3 years ago on this website that the only techno silver bullet I believed in against climate change was room-temperature superconductors, as this would help tremendously on
- interconnections,
- energy storage,
- efficiency,
And obviously help with plasma research, that would then help with both fusion and space catapult.
I was disappointed way too much by tech news in the last 10 years, but if this is true, I'd be really happy.

I was always curious about that. The ability to hold extreme electrical currents means superconductors also produce extreme magnetic fields, which I presume will happily induce induction currents in whatever conductive material is nearby. If that material is non-superconductive, than it will start sapping the electromagnetic energy from said superconductor as the eddy currents get resisted, getting hot in the process.
What I guess I'm saying is that I'm not sure how you're supposed to build a superconductive grid or motor without also turning everything around it into an induction stove when you turn it on.

Electromagnetic induction involves the inductor, too. With a conventional electromagnet in a changing field, there is a current (an opposite current, in a sense) induced in the electromagnet's winding which is how the energy transfer occurs. The coil's apparent resistance increases as it moves through the field. But superconductors have no resistance :)
Since a superconductor rejects induction from outside magnetic fields (Meissner effect) they do not inductively couple in the same way. Once energized and then looped, a superconducting magnet behaves more like a permanent magnet.
With regard to use in power storage, strong magnets of any kind are rather inconvenient (even dangerous) around anything magnetic.
But for local/grid storage, it's perfect. Also, infinite magnets, this might allow for less neodymium in renewable. And probably dozen new applications we don't think of yet.
