Reply to comment by super_shizmo_matic in Rolls-Royce successfully tests hydrogen-powered jet engine | Britain's Rolls-Royce said it has successfully run an aircraft engine on hydrogen, a world aviation first that marks a major step towards proving the gas could be key to decarbonising air travel. by yourSAS

Another hurdle is where to store the hydrogen on a plane? Current tanks in the wings, rudder, body of the plane will not work.

The amount of space needed for the tanks is substantial and has to come at the expense of passengers and their luggage. It's the same issue for battery powered airliners. The technology isn't feasible with todays or near-future technologies.
