Superconducting Cables for a Sustainable Energy Transition
Superconductors – materials that can conduct electricity without any resistance – were discovered over a century ago. As these materials must be cooled to very low temperatures to achieve superconductivity, they have not been used to transport electricity over long distances to date. But this could soon change, with researchers set to bring a number of systems for long-distance electricity transmission to market maturity. Among these is a dual-benefit technology: a superconducting cable that is cooled with hydrogen, enabling the delivery of electricity and hydrogen to facilities such as harbours and cement works.
