The objective of this project is to provide CERN expertise in vacuum systems to support ongoing industrial efforts to develop innovative superconducting cables capable of handling the increased share of renewable energy necessary to achieve decarbonisation. The project will be carried out in collaboration with SuperNode, a cutting-edge global technology development company that designs superconducting connection systems to connect renewable generation and increase grid interconnection in mature markets.

CERN and SuperNode have collaborated to develop a novel cryostat for superconducting cables. The testing campaign at CERN provided key insights to select suitable materials and refine the cryostat design. The collaboration drew upon CERN's expertise in vacuum and materials science to develop innovative energy transmission cables for use in the world outside of the laboratory. By replacing traditional stainless corrugated sheaths with polymer-based advanced materials, this new cable insulation reduces losses and increases the distance between cooling stations more than fivefold - significantly enhancing operational efficiency and cost.
