I'm not super knowledgeable in this area, but this seems like a great idea. I remember when hydrogen cars first came out, and the biggest issue was that there was almost nowhere to refuel. The nearest fueling station to where I lived was about an hour away. With planes, the airports will have fueling stations. IIRC, it's significantly better for the environment than existing jet fuel. The range was pretty good for cars, so I assume it will be for planes as well.
Would it be safer than combustible jet fuel?
