Irish company SuperNode and Cern, the European Laboratory for Particle Physics, have teamed up to create innovative insulation for superconducting cables to improve energy transmission and facilitate the transition to renewable energy. The collaboration harnesses Cern’s expertise in cryogenics and vacuum, as well as its facility in particle science and accelerator technology, to test and analyse sample materials and subsystems suitable for SuperNode’s superconducting cable systems. If successful, the partnership could enable electricity transmission over long distances using superconductor materials with no losses, potentially facilitating the creation of a supergrid in Europe. SuperNode was established by energy entrepreneur Eddie O’Connor to develop ground-breaking solutions for power transmission by developing energy transmission cables that harness the characteristics of superconductive materials.
