Superconducting Magnetic Energy Storage: Status and Perspective
Abstract — The SMES (Superconducting Magnetic Energy Storage) is one of the very few direct electric energy storage systems. Its energy density is limited by mechanical considerations to a rather low value on the order of ten kJ/kg, but its power density can be extremely high.

Energy Stored on a Capacitor
This energy is stored in the electric field. A capacitor. =. = x 10^ F. which is charged to voltage V= V. will have charge Q = x10^ C. and will have stored energy E = x10^ J. From the definition of voltage as the energy per unit charge, one might expect that the energy stored on this ideal capacitor would be just QV.
