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.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Superconducting_magnetic_energy_storage" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Superconducting_magnetic_energ...</a>
