Hydrogen helicopters

Sept 07,2018
Drones powered by Doosan’s hydrogen fuel cells are displayed for the first time at the International Drone Conference and Exposition (InterDrone) held in Las Vegas between Sept. 5 and 7. According to the company, the drone power pack developed by Doosan Mobility Innovation, which was set up in 2016, can last up to two hours on a single charge. Current drones can typically remain airborne for only 20 to 30 minutes. [DOOSAN]
