H3 Dynamics hydrogen-powered UAVs including airships, multi-rotors, and VTOLs will be able to further boost flight durations by a factor of 3 over pressurized hydrogen systems, or a factor of 10 compared to batteries. “We are proud to be working with Hylium to move hydrogen-electric flight propulsion to the next level.” “When combined, our global best-in-class solutions achieve the global performance limit for low-altitude electric powered flight” said Taras Wankewycz, H3 Dynamics CEO. With pressurized hydrogen, that range reduces to 400km, which is still 3 times more than a battery-powered equivalent. This will potentially vastly expand the scale of delivery drone, mapping and ISR missions. The 25kg hydrogen-electric propulsion UAV demonstrated by H3 Dynamics last July in France will be able to fly over 900km with a single fill. ![]() Cryogenic (liquid) hydrogen stores 3 times more energy as compressed gas in the same volume. Moving to liquid hydrogen represents a significant capability leap for small electric-powered unmanned systems. H3 Dynamics’ team developed a special fuselage design that can store a small LH2 tank and manage the thermal behavior of all the propulsion sub-systems. ![]() The companies are combining the strengths of Hylium’s liquid hydrogen storage and liquification solutions, and H3 Dynamics’ distributed hydrogen-electric propulsion nacelles, ultra-light fuel cells, and new hydrogen drone refueling stations. Hylium and H3 Dynamics technologies are currently being integrated to attempt a 3,300km crossing of the South Atlantic, in a program led by ISAE SUPAERO Toulouse, one of the world’s leading aerospace engineering schools. H3 Dynamics and Hylium Industries have joined forces to boost the performance of zero emission hydrogen-electric flight for a cross-Atlantic demonstration drone flight.
