Superconducting Magnets for Grid-Scale Storage - Technology Review

Superconducting Magnets for Grid-Scale Storage - Technology Review: Although the cost of superconducting wire has dropped significantly in recent years, Ramanan admits that it would need to fall by another 300 percent for SMES to be competitive with other grid-scale energy-storage technologies. He says reducing wire cost is a significant technical challenge but adds that taking on such challenges is the purpose of projects funded by ARPA-E.
