The new cables are based on superconducting materials, as when cooled down to very low temperatures carry over 100 times more current than copper conductors and this completely without energy losses.
SCARLET develops medium-voltage DC cables for multiple purposes. For instance, the high current carrying capability of the cables allows for a reduction in voltage level, leading to smaller and much less expensive equipment at offshore wind power farms. Another novelty to be developed is the transport of electricity and hydrogen in the same pipeline.
SCARLET is coordinated by SINTEF
