Next-Generation Cryo-Electric Hydrogen-Powered Aviation: A Disruptive Superconducting Propulsion System Cooled by Onboard Cryogenic Fuels

The idea of hydrogen (H
₂
)-powered airplanes has recently attracted a revitalized push in the aviation sector to combat carbon dioxide (CO
₂
) emissions. However, to also reduce, or even eliminate, non-CO
₂
emissions and contrails, the combination of H
₂
with all-electric solutions is undoubtedly the best option. This article explores the next wave of disruptive technological developments needed to scale up zero-emission aviation beyond 2035. With respect to conventional electrical propulsion, major breakthroughs will be needed in terms of reducing the voltage level while increasing system-level power density and overall efficiency. We show how a next-generation H
₂
-powered aircraft could take advantage of onboard cryogenic fuels to cool the electrical components, enabling a cryo-electric superconducting drivetrain that could lead to extraordinary performance.
