HES Energy Systems

HES designs, manufactures, and commercializes the world`s lightest fuel cell systems for aerial mobility and autonomous devices in the field. HES was founded in Singapore in 2009 and now spans the globe with offices in France and the United States. Since 2006 AEROPAK powered all kinds of mini fixed-wing UAVs around the world, ever since setting an FAI world record in 2007. This latest model is a scaled-up, all-inclusive, hybrid hydrogen-electric propulsion system designed to simply connect to the electric motors of larger manned or unmanned electric aircraft.
