Periodic Reporting for period 1 - SUBRACABLE (Making Superconducting power grids a feasible solution for Europe)
Reporting period: 2023-09-01 to 2024-08-31
Power transmission is a critical step in electrifying and decarbonizing Europe. The construction of cross-continental
grids for transmitting large amounts of power over very long distances has become strategic. But using current cables
made with standard conductors entail prohibitive energy losses in such grids: 50GW would be wasted in a pan-European
75.000km 10GW High-Voltage Direct-Current (HVDC) grid, equal to the electricity produced by 50 power plants.
SUBRA, a spin-off from the Technical University of Denmark (DTU), has developed and patented a solution which will
revolutionise European grids by mass producing High Temperature Superconductor (HTS) power cables, with superior
properties, no limitation in length, and at an affordable price. This represents a ground-breaking option allowing: 90%
reduction of energy losses; 99% reduction of copper required; 75% reduction of Levelized Cost of Transmission (LCoT);
and using small underground lines rather than overhead lines.
