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.
