Seems like they could have some huge advantages for air travel. Part of the calculations in flight is that your vessel weighs less as the journey progresses, and for maximum efficiency you really only want to carry as much fuel as you need to get from point A to point B. A plane powered by batteries would never stop being heavy. Given the eye popping carbon costs of routine flights, clean hydrogen is worth pursuing for aircraft alone.
