I'm not so sure. The big issue with Hydrogen is transport, it's an absolute pain to deliver it to fuel stations all over the country. With planes though, you only need to deliver it to an airport. Airports are also very frequently placed next to large bodies of water, so with enough electricity you could make it on site. I'm willing to bet that Hydrogen will never take off for cars, but I think it could have a place for planes and ships, and even trucks in some situations.
