GenH2’s Cullen Hall to speak on liquid hydrogen efficiency for aviation

GenH2 Vice President Cullen Hall will present at HYSKY Society’s Fourth Annual FLYING HY virtual conference on Nov. 4, 2026, focusing on how thermal management can reduce liquid hydrogen losses for aircraft fueling. The session underscores the infrastructure challenges hydrogen aviation must solve to improve fuel availability and commercial viability.

Why it matters: - Hydrogen aviation needs more usable fuel delivered to the aircraft to improve operating economics. - Thermal management that reduces boil-off and venting losses can increase the amount of liquid hydrogen available across storage, transfer and fueling. - GenH2 says its work with the University of Illinois Urbana-Champaign adds research capability for next-generation aviation fuel systems.

What happened: - GenH2 announced that Cullen Hall, vice president of product development, will speak at the HYSKY Society’s Fourth Annual FLYING HY Virtual Conference on Nov. 4, 2026. - Hall’s presentation is titled “Keeping More LH₂ in Flight: Solving Losses Across the Aviation Fuel Pathway.” - The talk is scheduled for 3:45 to 4:05 p.m. Central Time. - HYSKY Society is hosting the virtual event for aviation innovators, engineers, researchers and industry leaders focused on hydrogen-powered flight.

The details: - Hall’s presentation will cover how advanced liquid hydrogen infrastructure and thermal management technologies can preserve more fuel for aircraft use. - The discussion will address losses during liquid hydrogen storage, transfer and fueling. - GenH2 highlighted its collaboration with the University of Illinois Urbana-Champaign to advance liquid hydrogen research for aviation. - The partnership includes on-site liquefaction capabilities for work on storage, transfer, refueling and aircraft fuel system components under cryogenic conditions. - Hall has also presented at industry conferences and served as an instructor for HYSKY Society’s Hydrogen Safety for Aviation Short Course. - GenH2 described itself as a technology leader in liquid hydrogen infrastructure systems, including Zero-Loss Controlled Storage and advanced hydrogen liquefaction. - Path2 Hydrogen AG, GenH2’s parent company, is a management holding company focused on the hydrogen infrastructure sector and is listed on the Frankfurt Stock Exchange under XETR: PTHH. - Path2 Hydrogen said it acquired GenH2 in early 2025. - HYSKY Society is a 501(c)(3) nonprofit focused on decarbonizing aviation and aerospace with hydrogen. - HYSKY’s stated mission includes hydrogen-powered eVTOLs, advanced air mobility, fixed-wing aircraft, UAVs, WIG craft and spacecraft.

Between the lines: - The announcement points to a key bottleneck for hydrogen aircraft: not just producing liquid hydrogen, but keeping losses low enough to make the fuel practical and economical. - GenH2 is using the conference appearance to connect its infrastructure message with academic research and broader industry adoption. - The partnership with UIUC suggests the company is positioning itself around real-world testing rather than lab-only development.

What’s next: - Hall is set to deliver the conference presentation during FLYING HY on Nov. 4, 2026. - More information is available from GenH2 and HYSKY. - Registration is available through the FLYING HY conference registration page.

The bottom line: - GenH2 is pitching thermal management as a practical way to make liquid hydrogen more viable for aviation by preserving more fuel from production to takeoff.
