Element One merges HES' ultra-light hydrogen fuel cell technologies with a distributed electric aircraft propulsion design. With virtually no change to its current drone-scale systems, HES' distributed system allows for modularity and increased safety through multiple system redundancies.
Element One is designed to fly 4 passengers for 500 km to 5000 km depending on whether hydrogen is stored in gaseous or liquid form. This performance is several orders of magnitude better than any battery-electric aircraft attempt so far, opening new aerial routes between smaller towns and rural areas using an existing and dense network of small-scale airports and aerodromes.
Refueling Element One will take no more than 10 minutes using an automated nacelle swap system that applies AGVs and automated warehouse operations such as those used by Amazon and Alibaba.
