Hydrogen-powered drone can fly long distances over land or water

Drones that can fly for long distances over land and water need to take off and land vertically so they can land on the deck of a ship or in densely populated areas when required. Researchers from TU Delft have partnered with the Royal Netherlands Navy and the Netherlands Coastguard to develop a drone powered by hydrogen that can take off and land vertically yet fly horizontally efficiently for multiple hours like a regular aircraft. Researchers on the project have successfully tested the drone in one of the most difficult scenarios that it will be used in, launching and landing from a ship at sea.
