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

Yes but also that is why Airbus is researching on this.
They think tech may ready to be able to overcome those issues and are gonna try make 3 different demonstrator, one normal frame that burn hydrogen, one lifting body, and one normal frame but fuel cell propeller.
As they are one of the 2 biggest company about planes, I think they know what they can achieve

It's not that you can't make a hydrogen powered aircraft, you can. The problem is that barring the government just straight up banning conventionally powered jets they won't be able to compete. It is just a physical fact that hydrogen’s energy density is awful and working with it is painful. Any aircraft running on hydrogen will either carry less cargo (people or stuff) or have significantly shorter range or some combo of both.
