With 15 leading organisations from research and industry, the EU-funded project Superconducting cables for sustainable energy transition (SCARLET) aims to develop and industrially manufacture superconducting cables in kilometric lengths in order to increase the pan-European transmission network capacity and electricity system flexibility. The kick-off meeting for the project will take place at the IASS on the 28th and 29th of September. Throughout this first get-together, partners from 7 European countries will plan in detail the tasks and developments within the various work packages of the project. They include offshore superconducting links, hydrogen-cooled superconducting cables, long-length cable systems, protection of the cable systems in the grid as well as economic studies. Upcoming priorities, next steps and opportunities for dissemination will also be discussed.
