There's two problems with your last post which have to do with physics.

1. Fuel Cells and the process of hydrolysis have a limit on their efficiency. Just like with ICEs there isn't much potential there.
2. Between Hydrolysis and the Fuel Cell, there are other lossy processes. Usually the tanks contain pressurized H2 and depending on the usecase even liquid H2. Modern automobile cases use 700-800 bars of pressure. That process is again at around 85% efficiency in a good case. Cooling applications further deteriorate the efficiency and need more energy for storage and/or losses during storage. There are other technologies in research right now, like metal hydride storage, where we'll have to see what exactly they can do (right now we're at the stage where we are promised an all-purpose hype, but mostly through the media and not the ones doing the work)

I'm not disputing that capitalism has it's thumb on the scale; as you've written, the synergy to use H2 derived from natural gas is one effect, but it doesn't stop them from advertising it as green. The physical limits though, one cannot argue with. Their effects would mean a lot more infrastructure that is necessary, with it more materials, which are limited too. Even if possible, we have limited construction capacity, which means that it would take us longer to reach the goal, when time is of the essence. Which leads me to the same conclusion, that where the advantages like power density isn't absolutely necessary or other solutions are not available, use a better solution.
