I think it'd be valuable for anything that conducts electricity, and where resistive losses are significant or where strong electromagnets are desired. So, long distance electricity transmission, motors, generators, MRI machines and magnetic confinement nuclear fusion reactors for example. That said, the material as synthesized might not be very good for some particular application. The current handling capacity might not be good enough, or it might not be physically strong enough to use as motor windings. I don't know enough to do the comparison, but I'd be curious how this new material holds up when compared to copper or aluminum wire in terms of current capacity, weight, strength, and cost of materials. One of the big reasons for skepticism about humanity's prospects for converting to a non-fossil-fuel based energy system is that there just isn't enough of the important metal resources to build all the batteries/EVs/transmission lines/solar panels/windmills we need. I myself am skeptical of the skeptics because I think the resource bottlenecks are overstated and there are usually acceptable workarounds, but I do think copper is going to be in very high demand over then next several decades. If we have a good, cheap copper alternative then that solves that problem. (It also introduces another, as we would then have to deal with enormous quantities of lead-based cabling.)
