To make a viable hydrogen powered airliner you need to basically rethink the concept of an airplane. Conventional kerosene powered planes store most of their fuel in the wings and it's not possible for hydrogen. Instead you need to build a wing-shaped (similar to B-2 bomber, but magnitudes bigger and for passengers) plane.

Not really. You can use cryogenic liquid hydrogen that doesn't need to be stored under high pressure. Let the boil off keep the fuel cold and burn the gas to keep the pressure down.

Either way it needs a bulky container and the shape of the standard wings isn't plausible neither for pressurised nor for liquid hydrogen. And storing it in the main fuselage is reducing cargo capacity.
