Over the past two decades, studies of large-scale superconducting magnetic energy storage (SMES) for commercial utility applications have focused on solenoidal configurations. This selection has typically been justified on the basis of cost. A toroidal configuration would have a much less extensive external magnetic field, which might be a desirable feature for siting a SMES unit where land is limited. This paper reviews the characteristics of large-scale toroidal and solenoidal coils ({gt}10 MWh, or 36 GJ) to establish a basis for quantitative estimates of the material requirements for these two SMES systems and compares the size dependence, scaling features, and the estimated costs for major material components.
