The energy content of current SMES systems is usually quite small. Methods to increase the energy stored in SMES often resort to large-scale storage units. As with other superconducting applications, cryogenics are a necessity. A robust mechanical structure is usually required to contain the very large Lorentz forces generated by and on the magnet coils. The dominant cost for SMES is the superconductor, followed by the cooling system and the rest of the mechanical stru…

Superconducting magnetic energy storage (SMES) systems
Abstract: Superconducting magnetic energy storage (SMES) is one of the few direct electric energy storage systems. Its specific energy is limited by mechanical considerations to a moderate value (10 kJ/kg), but its specific power density can be high, with excellent energy transfer efficiency. This makes SMES promising for high-power …
