I think hydrogen is full of possibilities. In fact, I can envision creating a huge bag of some sort, filled with hydrogen. If I then hang some sort of structure from it, I could use it to fly around the world. Might even put a little cigar bar inside, just to add a touch of luxury.

Yep, the carbonless future is going to be filled with wonders. Why didn’t anyone think of this before?

Or you could just put the gas in carbon fiber tanks and run fuel cells on it. Hydrogen in carbon fiber tanks is less of a fire risk than jet fuel in metal wing tanks. Hydrogen vents up and away during a breach and the flames rise above the source of the gas unlike jet fuel with pools under and on the structural breach and burns on that surface. Hydrogen hysteria is a mental problem not an engineering one.

Or turn it to liquid like the space shuttle used and fly conventional looking aircraft like Airbus plans to do.
