Everybody keeps talking about all the problems storing hydrogen, but that's just quitter talk. You know how you solve 'em quick and easy? You simply combine the hydrogen with some carbon to make a convenient liquid fuel! As a bonus, you don't even need to develop fancy new fuel cell tech: you can burn it in the same engines we already have.

(Half of me is serious, and the other half is making a Key & Peele style "motherfucker that's called gasoline" joke.)
