To me, liquid hydrogen does not make any sense in aviation (except maybe for rockets), because it's so difficult to store and handle on the ground, and even more onerous in the air. Also flying wings will be like riding in a rollercoaster, since the window seats are far from the axis of rotation when banking, etc. I've seen concepts for small (2-6pax) hydrogen fuel-cell electric planes using Toyota mirai fuel tanks, which make some sense. But synthetic hydrocarbons (eg butanol), and the process to make them sustainably, make much more sense to me as future aviation jet fuel.
