AeroDelft’s prototype liquid hydrogen powertrain during the cryogenic tank filling process, with visible frost forming on the LH2 lines. AeroDelft’s full ground setup for testing the hydrogen-electric ...

ZeroAvia is working with San Francisco startup Verne to bring an even more energy-dense form of hydrogen to the clean aviation space. Cryo-compressed H2 could reduce costs, speed up fueling, and ...

The Sirius Jet will fly up to 1,150 miles (1,851 km) at speeds up to 323 mph (520 km/h) on a clean liquid-hydrogen powertrain. It'll rise vertically off a pad thanks to a deflected vectored thrust ...

Researchers have designed a liquid hydrogen storage and delivery system that could help make zero-emission aviation a reality. Their work outlines a scalable, integrated system that addresses several ...

A new generation of "flying cars" promises to revolutionize urban mobility, but limited battery power holds them back from plying longer routes. A new hydrogen-powered variant from Joby Aviation could ...
