[QUOTE="Danllan, post: 6360658, member: 8735"] Great, except for the obvious fact it's wrong. If others don't do it [U]first[/U], then China - I note you have not mentioned the US...? - will have been gifted the rather brilliant come back of 'But [U]you[/U] don't...' Hydrogen can be stored elementally, but it is far easier to store in compound form - my guess is that this will be the way forward until technology makes better materials and methods viable. Water is an obvious one and there are many others more appropriate to end-use. But I think it right to note: a) fuel cell derived hydrogen fuel would only be stored for a very short period, often for near-immediate use; and b) that the best shroud to contain hydrogen is thought, by many, to be more hydrogen (concentric flask storage). Effectively reducing escape to zero, since the outermost flask 'leaks' directly to combustion. Not sure you're right about the speed of atmospheric escape: [URL]https://physics.stackexchange.com/questions/302555/why-doesnt-hydrogen-gas-exist-in-earths-atmosphere/302760[/URL] [/QUOTE]
