Superconducting Magnetic Storage (SMS) utilizes the magnetic field generated by a superconducting coil to store energy, leveraging the unique properties of superconductors to achieve near-zero resistance and rapid response times.
SMS addresses the need for ultra-fast and efficient energy buffering to maintain stable power quality in critical applications such as data centers, hospitals, and high-performance computing environments where rapid response times are essential.
A direct current circulates in a superconducting coil that is cooled below its critical temperature using cryogenic fluids. The resulting magnetic field stores energy with minimal losses. When power quality issues arise, the stored energy can be rapidly tapped by reversing the current, thus providing instantaneous support without significant delay or loss.
The manufacturing process involves creating superconducting coils from materials like niobium-titanium or niobium-tin, which must be cooled below their critical temperatures to exhibit zero resistance. This requires precise fabrication techniques and the use of cryogenic cooling systems.
SMS devices are built by winding superconducting wire into a coil, typically using multi-turn configurations for higher energy storage capacity. The coil is then integrated into a cryostat that maintains the operating temperature below the critical point of the superconductor. The entire system must be carefully insulated to prevent heat leakage.
