Disastrous, as my post 38 says. Compressed H2 is much less dense than the liquid, which itself is 11 times less dense than gas.
If you try to use compressed H2 for transportation, you get gigantic, enormously heavy tanks, and even more limited range.
Even worse, compressed gas tanks are more dangerous than liquid dewars because they can (and will) explode. Common metals cannot be used for compressed hydrogen because of a phenomenon called 'hydrogen embrittlement', which forces the tanks to become gigantic, heavy, and costly, which I guess is a home run for the environmentalists and luddites...such as you.

Go BACK to the literature and learn a bit about the work on new, super-strong composite tanks. You are half right--IF you use gaseous hydrogen for transportation (which is NOT what I said, by the way--I was talking about the hydrogen economy, which involves ALL energy usage--not just transportation.) the tanks DO need to be super-strong.
If there is a luddite, on this thread, you're it. Personally, I have more confidence in the abilities of my fellow scientists and engineers here in the US to solve these problems than you appear to.
