How much electrical energy can be stored in superconducting solar container

The storage capacity of superconducting systems can vary significantly based on various factors, including the design of the system, the materials used, and the operational parameters. Typically, capacities can range from tens of kilowatt-hours (kWh) to multi-megawatt-hours (MWh). The perpetual current loop to store energy, mentioned in the previous paragraph, is known as the superconducting magnetic energy storage (SMES). Similarly, a superconducting power transmission line would reduce resistive losses. External power charges the SMES system where it will be stored; when needed, that same power can be discharged and used externally.
