Yes, Hydrogen combines with Oxygen to make water and release heat. If you have ever held a match near gasoline you may have noticed that gasoline tends to do the same sort of thing... (making water and carbon dioxide in this case). Fyron is still correct when noting that Hydrogen is not as risky as the public percieves it to be (bad risk assesment, at the time dirigible travel was probably safer than airplane travel which was still in its infancy). I would tend to argue that the Hindenberg got played up in the press at the time bc/ dirigible technology was backed by the Germans and German/US relations were on their way down in the run up to World War II. This misperception that hydrogen is horribly dangereous is unfortunately still with us.
