You can use superconductors for energy storage. An inductor stores energy, but can not be used for long-term energy storage due to resistance. A superconducting inductor can be used to store energy, as there is no loss due to resistance. https://en.wikipedia.org/wiki/Superconducting_magnetic_energy_storage https://en.wikipedia.org/wiki/Superconducting_magnetic_energ...
