> You can make it from electrolysis, but it's much more expensive to do so, so that won't happen.
I'm not convinced by that. The cheaper electricity gets, say the way PV is absurdly cheap these days, the less the inefficiency of electrolysis matters.
What doesn't change with cheaper PV etc. is that hydrogen is so hard to work with or store, both as a gas and as a liquid.
I can't rely on my gut feelings or comparisons to e.g. the space shuttle external fuel tank to say if these problems can be "solved" well-enough at an acceptable cost, as I've only got a GCSE in chemistry from the turn of the millennium.
