Not sure why you're being downvoted. This is the reality of the situation. I don't really see hydrogen being used in aircraft either, honestly. It's not even the energy imbalance, it's storage in the vehicle. It's not Hindenburg levels of unsafe but it's definitely worse than batteries and maybe gasoline. The amount of energy you can store per unit volume is only about twice a Li-ion cell (slightly better by weight, but that's not the issue in cars and supporting equipment further hurts this) and will likely be no better than the next generation of LiS cells.
