Reply to comment by Vickrin in 'Landmark achievement': Rolls-Royce and easyJet hail successful hydrogen jet engine test by Wagamaga

Thanks for the info!

So a hydrogen jet engine is... less than useless?

Exploring the concept is never wasted, people might learn something.

Putting a hydrogen engine in an aircraft is not going to be a viable option for the forseeable future.

Aircraft are probably one of the hardest things to move to a green fuel source.

Batteries are also awful when it comes to aircraft.

Plus hydrogen leaks the most out of all fuels. Magnetic bottles would work better imo.

What if we just used it at lower pressures and filled blimps with it?

Not really, Remeber, the most powerful rocket are hydrogen+oxigen.
The bigger the amount you want to store, the less is the coat of the container, as container weight grow as square(perimeter), while volume contained grow as cube.
A hydrogen train make a lot of sense and they have been already successful experimented, but will never take off until cost of diesel is cheaper.
