Why Liquid Hydrogen?
Using liquid hydrogen as a fuel offers a fundamental advantage over gaseous hydrogen for aviation: significantly lower tank weight at equivalent energy content. Gaseous hydrogen requires pressure vessels capable of withstanding 250–350 bar — resulting in heavy storage systems with poor fuel-to-tank weight ratios.
Liquid hydrogen, stored at cryogenic temperatures around -253°C, eliminates the need for high-pressure containment, enabling lighter, more compact storage and the extended range that aviation demands.
Built on Experience
H2FLY's expertise in cryogenic liquid hydrogen storage is grounded in real-world application.
In 2023, H2FLY led the world's first piloted flight of a liquid hydrogen-powered electric aircraft gaining hands-on experience in LH2 storage system integration and boil-off management that directly informs our tank system development today.
