This is a most excellent place for technology news and articles.
Leaking hydrogen into the upper atmosphere sounds like a bad idea. It extends the life of methane, making the green house problem worse. I really hope that they reduce the leaking issue to a minimum.
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.
But the short term profits!!!
