The Korea Institute of Machinery and Materials has developed a 5-kilowatt hydrogen fuel engine that is strong enough to power industrial lift drones with a weight of 20 to 30 kilograms.
The engine supplies hydrogen fuel through the direct spray method while optimizing engine parameters, such as spray and ignition.
It has a maximum output of more than 7 kilowatts.
Batteries currently power unmanned mobility devices.
Researchers are also trying to develop gasoline engine hybrids or hydrogen fuel cell systems to extend flight time.
Hydrogen engines are also free from carbon emissions.
