This 150 kg-class vertical takeoff and landing (VTOL) unmanned aerial vehicle (UAV) stands out for its long endurance and versatile applications

Hydrogen propulsion is rapidly becoming a cornerstone of sustainable aviation. Yet, as Raffaele Russo’s experience leading hydrogen-electric flight development at Joby Aviation and later founding Otter Stone has shown, fire safety, permitting, and code compliance remain the largest bottlenecks to adoption.

Hydrogen’s properties are a double-edged sword. On one hand, it’s a fantastic energy carrier. On the other, it’s a fire hazard that requires meticulous control. Here are the key risk factors that elevate hydrogen fires to a whole new level of danger:

If you don’t understand how hydrogen behaves in a fire, I’m sorry — but you don’t belong in the conversation about hydrogen aviation.

HYSKY Society, the nonprofit dedicated to advancing hydrogen in aviation and aerospace, has announced the appointment of two distinguished leaders to its Board of Directors: Dr. Anubhav Datta, Alfred Gessow Professor at the University of Maryland’s Department of Aerospace Engineering, and Kenneth Swartz, renowned aviation journalist, communications strategist, and historian.

“Hydrogen Aircraft & Prototypes” isn’t theory—it’s proof. These are the machines and minds turning research into flight, concept into certification, and prototypes into products.

Dr. Anita Sengupta is quite the celebrity in the aerospace community and was even interviewed on William Shatners TV show, "I Don't Understand."

Commentary from Danielle McLean of HYSKY Society A recent Simple Flying feature by Joshua Eyre does a strong job surveying aviation’s decarbonization options—hydrogen, electric, and sustainable aviation fuel (SAF). It name‑checks efforts from Airbus, H2FLY, and ZeroAvia. It’s informative and timely. https://simpleflying.com/hydrogen-electric-saf-fuel-lead-commercial-aviation-into-2030s/ Where the otherwise excellent article stumbles is framing . The headline says Hydrogen vs

Project Newborn, a major initiative led by Honeywell Aerospace, which is targeting a first hydrogen-powered flight in 2028.

Hydrogen aviation is accelerating into a new era, thanks to regulatory breakthroughs, advanced propulsion systems, and growing demand across both fixed-wing and eVTOL aircraft sectors. ZeroAvia, a pioneer in hydrogen-electric propulsion, is leading the charge with modular, aerospace-grade fuel cell systems designed for maximum efficiency, endurance, and scalability. https://zeroavia.com/blogs/new-drivers-for-hydrogen-fuel-cell-adoption-in-aviation/ Hydrogen Fuel Cells Gain Mo

HYSKY Monthly is proud to feature Dr. Nicolò Baiguini, lead hydrogen project engineer at Design Tech Centre (DTC), as the distinguished speaker for October’s HYSKY Monthly #71, airing October 20, 2025, from 10:30 AM to 12:00 PM CDT.

HYSKY Society and the Vertical Flight Society’s CAT Discussion Group convened a lively, deeply practical webinar on how Supplemental Type Certificates (STCs) are accelerating the entry of advanced propulsion and systems into real aircraft. Moderated by Mike Hirschberg (H2 Advisors), with featured talks by David Webber (FAA) and Ken Swartz (Aeromedia Consultants), the session blended policy mechanics, field-proven history, and what’s next for eVTOLs, hydrogen, hybrid-electric,

Company will Showcase Liquid Hydrogen Technology and Explain its Use in Space and Advanced Clean Energy

Teledyne Energy Systems has successfully launched its Hydrogen Electrical Power System (HEPS) aboard Blue Origin’s New Shepard rocket, marking a pivotal step in advancing hydrogen fuel cell applications in space, with implications for future lunar and deep space missions.

Beyond Aero, a world leader in hydrogen-electric propulsion for business aircraft, today is reaching Technology Readiness Level 6 (TRL6) for its hydrogen-electric powered aircraft. This achievement is validated by a full-scale propulsion system test campaign in a representative environment, a critical milestone moving Beyond Aero from laboratory promise to real-industrial viability. The TRL6 demonstration took place at Beyond Aero’s new integrated hydrogen-electric powertrain

The Hydrogen Fire Safety Online Short Course provides a foundation in the hazards, standards, and emergency practices required for safely integrating hydrogen into aviation.

HYSKY Society and the Vertical Flight Society’s (VFS) Commercial Air Transport (CAT) Discussion Group are proud to announce a joint webinar exploring how Supplemental Type Certificates (STCs) can accelerate the adoption of advanced aviation technologies.

Conflux Technology has announced its role in supporting Airbus’ ZEROe project by developing an advanced heat exchanger using additive manufacturing, designed for hydrogen-electric propulsion systems. The heat exchanger, currently undergoing a technology readiness maturity assessment, plays a critical role in thermal regulation within megawatt-class fuel cell systems.

Japan has unveiled its boldest aerospace initiative in decades: the ¥1 trillion ($6.8 billion) Space Strategy Fund, a ten-year program launched in 2024 to supercharge the nation’s space and hydrogen-powered aviation sectors. The effort aims to double the size of Japan’s domestic space market to ¥8 trillion ($54 billion) by the early 2030s while spearheading breakthroughs in hydrogen propulsion, reusable rockets, eVTOLs, and advanced composites.
