Hydrogen as a fuel for road vehicles only makes sense if electricity is cheap and very abundant. And the way to abundant, cheap electricity is by application of new and much more safe Small Modular Nuclear reactors, several designs of which are all ready for introduction and widespread use. These units could be built in a factory and moved to location by rail car or semi-trailer trucks, and assembled on site, within WEEKS, rather than years.

I’m all aboard. The only reason nuclear power was abandoned was out of fear generated by media sensationalism and environmental extremists after some meltdowns. Everyone was afraid and willing to throw the baby out with the freaking bathtub. Technology today makes nuclear generation safer, cheaper and producing plentiful energy. But, nooo, nuclear bad.
Thise small Nuke Electric generators are a very good answer.
Being used already overseas somewhere.
Very efficient and safe.
