Here is an aircraft that can achieve a range of up to 900km on liquid nitrogen. H3 Dynamics’s 25kg test aircraft also can go for 350km with pressurized hydrogen. It has a externalized nacelle design that frees up 30L of fuselage volume.
As the company explains, its hydrogen propulsion nacelles could become a snap-on add-on for battery-powered unmanned eVTOL or fixed wing cargo drones.
