As hydrogen-powered aviation moves from concept to commercialization, the industry’s biggest hurdle isn’t just generating fuel — it’s keeping it from boiling away before it reaches the aircraft. GenH2’s upcoming presentation tackles that exact problem.
GenH2 Corp., a subsidiary of Path2 Hydrogen AG (XETR: PTHH) and a developer of liquid hydrogen (LH₂) infrastructure, has confirmed that Cullen Hall, Vice President of Product Development, will take the virtual stage at the HYSKY Society’s Fourth Annual FLYING HY conference on November 4, 2026. The event, which is being held online, will feature Hall’s session titled “Keeping More LH₂ in Flight: Solving Losses Across the Aviation Fuel Pathway,” scheduled from 3:45 to 4:05 p.m. Central Time.
Hall’s presentation zeroes in on a central challenge for hydrogen aviation: ensuring that as much fuel as possible survives the journey from production to the aircraft’s tank. He will outline how advanced infrastructure and thermal management technologies can reduce boil-off and venting losses during storage, transfer, and fueling operations — a key factor in improving both operational efficiency and the economic case for hydrogen-powered flight.

Beyond the technical deep dive, Hall will spotlight GenH2’s partnership with the University of Illinois Urbana-Champaign (UIUC). That collaboration brings on-site liquefaction capabilities to the university, enabling research into liquid hydrogen storage, transfer, refueling, and aircraft fuel system components under real-world cryogenic conditions.
“Keeping more liquid hydrogen available for aircraft fueling is critical to making hydrogen aviation commercially viable,” said Hall. “Advanced thermal management technologies help preserve valuable fuel throughout the aviation supply chain. Our collaboration with the University of Illinois is another important step toward advancing the infrastructure needed to support hydrogen-powered flight.”
Hall brings deep expertise to the topic, with a background in liquid hydrogen infrastructure and cryogenic technologies. He has presented at leading industry conferences and has served as an instructor for HYSKY Society’s Hydrogen Safety for Aviation Short Course.
The FLYING HY conference, organized by the nonprofit HYSKY Society, gathers aviation innovators, engineers, researchers, and industry leaders focused on hydrogen-powered flight. This year’s virtual agenda covers aircraft technology, hydrogen infrastructure, propulsion, safety, and commercialization efforts.
For those interested in attending, registration for the FLYING HY virtual conference is available online, and more details can be found on the GenH2 and HYSKY websites.
