Large-scale MgB 2–YBCO hybrid coil: Fabrication and performance validation for application in superconducting magnetic energy storage for grid stabilization
In February 2025, 16 MgB 2 –YBCO hybrid coils had been completely produced and were ready to be assembled into a high-temperature superconducting magnetic energy storage (HTS-SMES) device. This is the first time in the world that an HTS-SMES device with an energy capacity of 10 MJ has been developed, and the entire process was independently completed by a Chinese group. This marks a further maturation of the technology for large-scale fabrication of high-quality, homogeneous high-temperature superconducting hybrid coils, as well as the manufacturing of high-performance SMES devices. In addition, the ability to regulate grid fluctuations will be further enhanced.
