SCARLET

Superconducting medium-voltage cables could become the preferred solution for energy transmission from renewable generation sites to the electricity grid. Onshore cables can save on size, and offshore cables eliminate the need for costly converter stations required by high voltage DC cables. The EU-funded SCARLET project will design, manufacture and test liquid-nitrogen-cooled cables based on high-temperature superconductivity as well as liquid-hydrogen-cooled magnesium diboride cables. The project will also test a high-current superconducting fault current limiter module for grid protection. The use of superconductor technology can accelerate the transition towards a low-carbon society by offering a 15 % reduction in total cost for offshore windfarms and creating 5 000 new jobs in sustainable energy.
