H3 Dynamics and Hylium to bolster liquid hydrogen-electric capabilities

H3 Dynamics and Hylium Industries have joined forces to boost the performance of zero emission hydrogen-electric flight, by combining the strengths of Hylium’s liquid hydrogen storage and liquification solutions, and H3 Dynamics’ distributed hydrogen-electric propulsion nacellesultra-light fuel cells, and new hydrogen drone refueling stations. Moving to liquid hydrogen represents a big capability leap for small electric-powered unmanned systems.

What does the partnership mean for the industry?

Cryogenic (liquid) hydrogen stores 3 times more energy as compressed gas. This means delivery drones will be able to fly further, mapping and ISR missions could be done on a much bigger scale. 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. With pressurized hydrogen, that range reduces to 400km, which is 3 times more than a battery-powered equivalent.

Now all the various forms of hydogen drones and UAVs powered by H3 Dynamics including hydrogen airshipsmulti-rotorsvertical take-off and landing (VTOL), have a way to further boost flight durations by another factor of 3 over pressurized hydrogen systems, or a factor of 10 compared to batteries. H3 Dynamics also recently announced a first hydrogen production, and automated hydrogen refueling mobile station for hydrogen UAV operations.

“When combined, our best-in-class solutions achieve the global performance limit for low-altitude electric powered flight. We are proud to be working with Hylium to move hydrogen-electric flight propulsion to the next level,” said Taras Wankewycz, CEO at H3 Dynamics.

Why is the partnership mean for the two companies?

Named H2FIELD the mobile station produces hydrogen from water and delivers compressed hydrogen gas tanks to the operator with little human intervention and no required hydrogen expertise. This partnership will upgrade the station so that it can fill liquid hydrogen tanks.

Developed in South Korea, Hylium’s tech provides one of the most advanced solutions and has already been proven in a number of applications. South Korea is leading the development for LH2 standardisation. A proposal was accepted as a draft standard by the ISO committee.

Hylium and H3 Dynamics technologies are 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’ team developed a fuselage design that can store a small LH2 tank and manage the thermal behavior of all the propulsion sub-systems.

LH2 tech is the next step in H3 Dynamics’ hydrogen-electric propulsor nacelles roadmap. A first twin engine cargo drone powered by the self-contained nacelles took off in Paris during the summer, using 2 compressed hydrogen tanks – one in each nacelle. The goal is to switch them out for liquid hydrogen tanks with a lighter construction and a higher fuel capacity.
