Electromagnetic energy storage systems can be used to store and release energy. A typical SMES system includes three parts: superconducting coil, power conditioning system and cryogenically cooled refrigerator. The superconducting coil is charged and the current will not decay, allowing the magnetic energy to be stored indefinitely. The stored energy can be released back to the network by discharging the coil1. Electrostatic energy storage systems use supercapacitors to store energy in the form of electrostatic field, while magnetic energy storage uses magnetic coils that can store energy in the form of electromagnetic field2. SMES is a grid-enabled device that can store and discharge enormous amounts of energy almost instantly3.
