Aviation accounts for roughly 2 percent of global CO₂ emissions, and the industry’s climate impact is growing. With the push toward sustainable flight, hydrogen has emerged as a promising alternative.
It carries more energy per kilogram than jet fuel and emits no carbon dioxide. But storing and using it safely on aircraft has posed major challenges, until now.
Researchers at the FAMU-FSU College of Engineering have designed a liquid hydrogen storage and delivery system that tackles several obstacles at once.
Their work could help make zero-emission, hydrogen-powered flight a practical reality.
“This design lays the foundation for real-world hydrogen aviation systems,” said Wei Guo, a professor in the Department of Mechanical Engineering and corresponding author of the study.
One system, three solutions
The system was developed for a conceptual 100-passenger hybrid-electric aircraft. It draws power from…
