the correct reaction would be to ask if the fear of carbon dioxde was justified, not to fear water instead.
clouds are water, but there's much more, invisible to the naked eye, the atmosphere is full of it, 70 percent are covered with water and it
evaporates under sunlight, comes down again as rain, which is of course very good for us.
i mean seriously, GW is a scam, as outlined many times.
hydrogen would be much preferrable to petroleum and even methane (aka. 'natural' gas) if H2 generation an fuel cells and could be made to work at
seriously high efficiencies, read approaching or surpassing those seen in electric power distribution and generation.
it could then be consumed locally via fuel cell, eliminating complicated wide area electric power network infrastructure (you'd need pipelines,
though) and it could be stored easily, unlike electric energy.
if such a goal is attainable, it's certainly worth it, the question is how realistic these goals are.
it's obvious, though that the underlying assumption is the use of nuclear primary power, although i presume you could use solar for heat and any
renewable for electricity, since storage is no real issue.

he left out absorbing materials for storage purposes, much of the rest is accurate, though and without adressing the more fundamental issues, fuel
cells will remain white elephants. i have no doubt that the whole thing is set up for failure, but that does not mean it will, just that the odds are
stacked against the 'hydrogen economy'.
