Abstract :
On the basis of a 22MJ/10MVA unit without stray field, the authors determine minimal performances for high Tc superconducting (HTS) wires, in order to obtain HTS superconducting magnetic energy storage (SMES) competitive compared with low Tc superconducting (LTS) ones. The cost equation mainly considers the wire volume, the fabrication process and losses. They then recommend HTS critical current densities and operating magnetic fields close to the present state-of-the-art for short samples. A 30% gain for HTS SMES compared with LTS one could be expected
