It is brought out that the Hindenburg was filled with hydrogen, and it exploded; but may not have been the cause of the disaster. The question is not whether hydrogen is flammable (of course it is, but less so than gasoline), but can it be contained properly. In the case of the Hindenburg, it was encased in flimsy, lightweight, highly flammable cloth with flammable weatherproofing -- obviously less than ideal. In that case, a simple static spark ignited the aircraft.
Todays hydrogen fuel cells create hydrogen contained in high pressures inside strong, leak-proof containers. Indeed, hydrogen is already in use as fuel under certain circumstances. With hydrogen fuel cell cars on the road already today for testing, we shall soon see if the dangers of hydrogen storage incite manufacturers to quit producing them.
