Super Coated Conductor Cable (SUPER3C)
Total cost:EUR 5 156 000

Funding scheme:STREP - Specific Targeted Research Project
Several High Temperature Super conducting (HTS) cable prototypes have been manufactured in the world with HTS bismuth-based multifilamentary wires as current carrying elements. This technology is now moving towards the pre-commercial stage through already announced or under discussion multi-hectometre cable projects. However, these multifilamentary wires are expected to be replaced in the near future by a generation of cheaper HTS tapes, the Coated Conductors (CC).
The SuperSC project therefore aims at establishing the feasibility of a low-loss HTS energy cable using CC tapes. It comprises the development, manufacturing and testing of a functional model consisting of a one-phase, 30-meter long, 10 kV, 1 kA cable with its terminations. It is expected to be the first HTS cable in the world using only CC tapes as current carrying elements. Besides the wide range of competences that it represents through the involvement of well-recognized groups, the SuperSC project consortium guarantees the access to the world leading processes for the manufacturing of the two most critical cable components which are the HTS tape and the cryogenic envelope.
Most of the HTS tapes will indeed be fabricated through Ion Beam Assisted Deposition (IBAD) and High Rate Pulsed Laser Deposition (HR-PLD), a combination of well-established processes leading to the highest performances, whereas the cryogenic envelope will be supplied by a team which has more than 20 years of experience in that field. In addition, the test, in a cable configuration, of a CC tape with a chemically deposited HTS layer will set the basis for future developments aiming at defining the best combination of processes to further reduce the cost of CC tapes and, consequently, of CC cables.
