Isn’t it flammable? I’d think leaks would have to be zero for even more basic reasons.

Yes, it's very flammable. But it's also very light. Lighter than Oxygen. And the molecules are small which means most air tight applications don't work well. Even the tanks they make now still has this issue where hydrogen molecules can escape through the barriers over time.
