How do we store energy electrically?
If we want to store energy electrically, we can do this either through a voltage storage or a current storage. Inductance, or more precisely a superconducting inductance, serves as the current storage. The construction and functioning of such a superconducting magnetic energy storage (SMES) system is described in this chapter.
How does a SMEs energy storage system work?
The stored energy can be released to the network by discharging the coil. The associated inverter/rectifier accounts for about 2–3% energy loss in each direction. SMES loses the least amount of electricity in the energy storage process compared to other methods of storing energy. SMES systems offer round-trip efficiency greater than 95%.
