Michael Barnard concludes his conversation with John Fitzgerald, CEO of Supernode. They explore the game-changing potential of superconducting transmission technology. Superconductors, capable of carrying electricity with zero resistance at extremely low temperatures, are already used in applications like MRI machines and are now poised to revolutionize urban power distribution.
Fitzgerald highlights advances in cryogenic systems, such as smooth bore cryostats, which allow cables to run three times longer between cooling stations, reducing infrastructure needs and enhancing efficiency. The episode spotlights projects like Munich’s upcoming 12-15 km superconducting power cable, which will transfer more power using less space, offering a cost-competitive solution for urban energy demands. Fitzgerald also underscores the importance of developing a European super grid and anticipatory investments in high-capacity power corridors to address growing renewable energy integration and reduce curtailment. He contrasts Europe’s efforts with rapid grid advancements in India and China, emphasizing the need for proactive planning and investment.
Looking ahead, Supernode aims to commercialize its technology by the end of the decade. Fitzgerald calls on policymakers, utilities, and system operators to bridge gaps in energy infrastructure, establish partnerships, and secure funding to promote innovative transmission solutions for a sustainable future.
