Could hydrogen-powered drones soon hit the skies?

South Korean technology firm Doosan says its hydrogen fuel cell means drones will be able to stay in the air for up to two hours

A new hydrogen fuel cell designed for drones has been announced.

South Korean technology firm Doosan has unveiled new hydrogen fuel packs it claims can allow unmanned aerial vehicles to fly for up two hours on a single charge.

This contrasts with existing batteries, which can generally power drones for around half an hour.

Doosan says its technology allows drones to be ‘recharged’ in just ten minutes by attaching a new oxygen container, increasing the amount of time they can spend in the air.

It says this make hydrogen the ideal fuel source for drones used for infrastructure inspection and public safety purposes.

Lee Doo-soon, CEO of Doosan Mobility Innovation, said: “We are establishing hydrogen supply and recharging systems, delivery service and various Internet of Things based services that would enhance drone flights and customer convenience.”
