Conceivably, though the power density of superconducting energy storage is very low and will likely remain low. It is currently used at grid-scale to smooth out power spikes, since they can charge/discharge their full capacity almost instantly. > SMES is also used in utility applications. In northern Wisconsin, a string of distributed SMES units were deployed to enhance stability of a transmission loop. The transmission line is subject to large, sudden load changes due to the operation of a paper mill, with the potential for uncontrolled fluctuations and voltage collapse. https://en.wikipedia.org/wiki/Superconducting_magnetic_energy_storage https://en.wikipedia.org/wiki/Superconducting_magnetic_energ...
