To produce hydrogen you need low cost electricity or high temperature heat. How are you going to produce one or both? Ay, there is the rub!
Tullio

I recall in chemisty class in high school watching Hydrogen being produced with relatively little effort. 2 paladium probes and 2 cupped towers with a connectiing piece. Fill with water. turn on elecctricity and hydrogen shows up on one side Oxygen the other. In large scale operations this might take time to implement on a larger scale than is already being done.

It still requires much more energy going in (electricity) than you get out in the form of hydrogen.

Set up the hydrogen plants where there is abundant renuable energy (solar in desert regions, tidal or wave on the coast, geothermal in the hot-spots, etc) and pipe the hydrogen to where you need it.

I would never be as cheap as pumping oil out of the ground but once the infrastructure is in place all sorts of interesting little technologies will develop.

Pure mathematics is, in its way, the poetry of logical ideas.

Albert Einstein

Hydrogen is a by product of some chemical processes. At Porto Marghera, near Venice, there is a big and extremely polluting chemical plant built in the Mussolini era. Now they are using its hydrogen output to put a green mask on the polluting plant and keep it working instead of closing it. Caveat emptor!
