Electricity has been around that long too though, yet there are no serious electric passenger planes (with a decent range)
It has it's flaws, but it may have a higher ceiling in terms of usefulness. They say they can make it work, which is more than I hear about electric planes for example.
We should be financially encouraging 0 carbon planes, without controlling how, then let the engineers work what tech to do it with.
You can also run an aircraft on biofuel with little to no modifications, with none of the downsides of hydrogen.
There is a lot of biofuel being made of other fuel types though, so no reason why production of aviation biofuel can't ramp up.
That requires lots of cropland though. Hydrogen can effectively be made by offshore wind farms etc.
It might work if we reduce standard fuel requirements for cars etc enough.
Most of what our liquid fuels are used for currently can be done by electric vehicles, it will be tasks like farm equipment, and vehicles and equipment working in remote areas, that will still require liquid fuels.
