The future of hydrogen aviation powered by H3 Dynamics’ distributed hydrogen propulsion nacelles has taken flight for the very first time in France. H3 Dynamics’ 25kg test aircraft is already a breakthrough, with an electric flight range of up to 900km on liquid hydrogen, or 350km with pressurized hydrogen. Its externalized nacelle design also frees up 30L of fuselage volume with no hydrogen nor any powertrain elements inside. H3 Dynamics’ hydrogen propulsion nacelles could potentially become a “snap-on” retrofit for battery-powered unmanned eVTOL or fixed wing cargo drones.Preparing for the arrival of much longer duration unmanned hydrogen flights - H3 Dynamics started to work on airspace safety with world-leading air traffic control companies. It has been building experience with high-volume enterprise data services being deployed in smart cities such as Singapore, and gradually coupling these with drone-agnostic charging stations.By starting at the lower-end boundary of regulatory and certification efforts, H3 Dynamics doesn’t need to wait until 2035 to begin its commercial journey. Now H3 Dynamics is already preparing its next steps.It is exploring liquid hydrogen integration as part of a joint-development with ISAE-SUPAERO in Toulouse launched in 2019. The objective is a historical and symbolic Atlantic crossing on hydrogen electric propulsion in the coming two years.And with airfield experiments feeding its digital twin capability for hydrogen aircraft design, H3 Dynamics is now working on a next generation platform powered by 6 independent hydrogen-electric nacelle systems. The aircraft will feature fast-refueling and will be used as a test bed for H3 Dynamics hydrogen-electric propulsion technology moving forward.Other, higher-visibility hydrogen aircraft proponents will fly larger size aircraft much sooner – but they will do so by converting existing aircraft using fuel cells sourced from the automotive world – and storing large amounts of gas or liquid hydrogen inside the main fuselage.
