Comparison of the ecoprofiles of superconducting and conventional 25 MVA transformers using the LCA methodology

a) Pre-commercial phase for cables and FCL only b) If available in long length: YBCO better than BSCCO better than MgB2 c) HTS: the only way for applications in the electric power sector d) Cooling costs (capital, running and maintenance costs) ≫ than HTS material costs e) Cost-effective cooling systems, Cryodielectrics for HV and new testing guidelines/codes f) Application research first, but material research too
