US researchers claim liquid hydrogen storage flight breakthrough
Researchers at the FAMU-FSU College of Engineering in Florida claim to have addressed “multiple engineering challenges simultaneously” by engineering a practical liquid hydrogen storage and delivery system that brings zero-emission aviation significantly closer to reality.
The study, published in Applied Energy, introduces a scalable system specifically designed for 100-passenger hybrid-electric aircraft.
The new design integrates hydrogen fuel cells with hydrogen turbine-driven superconducting generators, demonstrating how liquid hydrogen can be efficiently stored, safely transferred and strategically used to cool onboard systems during all flight phases.
“Our goal was to create a single system that handles multiple critical tasks: fuel storage, cooling and delivery control,” said Wei Guo, professor in the joint college’s Department of Mechanical Engineering and corresponding author of the study. “This design lays the foundation for real-world hydrogen aviation systems.”
