Watch: What is superconducting magnetic energy storage?
The superconducting coil stores the energy and is essentially the brain of the SMES system. Because the cryogenic refrigerator system keeps the coil cold enough to keep its superconducting state, the coil has zero losses and resistance. This coil may be manufactured from superconducting materials like mercury or niobium-titanium.
