A company from Germany has successfully tested a ground-based cryogenic fuel refueling procedure. In the nearest future
H2Fly makes its first manned flighton hydrogen fuel back in 2009, and most recently carried out pioneering work with a hydrogen gas system built into the Pipistrel Taurus G4 twin-aisle aircraft. Now the German company has equipped the same HY4 aircraft with a liquid engine with a storage system from Air Liquide.
Now H2Fly has announced its successful completionground tests for refueling. The company has already conducted extensive vibration and leak testing on the cryogenic tank, which is located separately on the left side of the fuselage and is well isolated from the pilot on the right side of the fuselage.

Replacing Jet-A jet fuel with an alternativeGoing carbon neutral is a challenge for the aviation industry. Getting to zero emissions is much more difficult. What works for cars and trucks doesn't work for airplanes—the batteries are too heavy and the hydrogen gas takes up too much space. At this point, intercontinental green aviation is likely to start using liquid hydrogen.
The problem is that if you cryogenically coolWhen hydrogen is in its liquid state, it still takes up a lot of physical space—about 3.7 times more than jet fuel. In addition, hydrogen remains liquid only if it is kept at temperatures below 20 Kelvin (–253 °C).
