I find your hydrogen story to be somewhat lacking in reality due to a couple of points.
  1. Hydrogen releases a lot of energy when burned. This is the good side, but because of the second law of thermodynamics hydrogen requires even more energy to hydrolyze from water. And the two so-called renewables wind and solar just don’t produce nearly enough energy to supply the transportation sector.
  2. Hydrogen has to be stored in compressed or liquid form. Liquid H is stored by NASA, but is dangerous and because it boils at a much lower temperature than even liquid N you A need a lot of energy to cook it and B it boils away fairly quickly. Which brings us to C hydrogen has to be compressed to extremely high pressures to get a reasonable amount of it in a tank which is smaller than the Hindenberg. This requires a great deal of energy and depending on the pressure it can be as much or more than energy needed to hydrolyze it in the first place. And let’s not forget D hydrogen is very good at escaping pressurized systems. Leading to the conclusion that
  3. Hydrogen is only marginally better than batteries in that it does not require tons of raw materials to make the storage systems and theoretically filling a hydrogen tank should be faster than charging a battery, but when you consider how totally dumb most people are, trusting them to handle a flammable gas connection at a couple of thousand bars is probably not a good idea
if you look at what gasoline is it is a mixture of H and C anyway so if it weren’t for the massive lie of the climate doom crazies about CO2 being a pollutant it’s better to just burn hydrocarbons.

The storage situation for hydrogen is its greatest problem. However, here comes Metal Hydride Technology using magnesium hydride. Upon complete hydrogenation, all the hydrogen is stored as solid magnesium hydride. Zero hydrogen gas can be released in its stable solid state.

4. I would add the container embrittlement problem caused by
hydrogen.

the very best solar energy product that provides energy simply and efficiently...the tree. been working tirelessly on a smokeless wood burning engine for a truck and even working on how to use green wood, you know, to appease the green party.
