13. Hydrogen is a problem

It's very small, so it leaks through any tank.

So far, the only major user of hydrogen power has been the space program, and they top-off the hydrogen tanks until the moment the vehicle launches.

Hydrocarbons of some sort are far more practical because their larger size avoids this problem.
