Increasing volume is not really that easy. You are constrained by aerodynamics and any additional material required to contain an expanded volume adds weight in addition to increasing drag. There is a reason all planes look relatively the same, and it is not because we just happen to think it is a pretty shape.
- VBprogrammer 7y agoThe problems of using hydrogen are practically non-existent compared to the problems of using batteries. Even if you use half the interior volume of the aircraft for hydrogen storage you are still in the realms of it being economically viable (though still challenging). 1lb of jet fuel has roughly 5kwh of energy. Of course you are going to get less than half of that out as useful work. But an airliner can carry 300000lb of fuel. So as a first order approximation you are going to need 10000+ Tesla battery packs to do the same job.
