Hydrogen derived from natural gas can not be used in fuel cells. Only hydrolysis hydrogen is viable.
It is one of 'many' reasons why hydrogen fuel will never be a thing.
Along with Hydrogen seeping through everything
Along with Hydrogen embrittlement
The energy efficiency loss to convert Solar/Wind/Nuc -> Hydrogen -> Mechanical or Solar/Wind/Nuc -> Hydrogen -> Electrical -> Mechanical
Will never be cost effective compared to Solar/Wind/Nuc -> Electrical(batt) -> Mechanical
Hydrogen has been known to man for a 1000 years, and yet
Gobal International WARS have been fought in the past century along with massive geopolitical maneuvering and trillions upon trillions of $$$ spent on the energy sector.
Do you really thing we'd be spending the $$$ we do for deep sea drilling if hydrogen was even close to being a viable resource?
No new technology has been developed that makes hydrogen useful. No. Fuel Cells are not it.
There just isn't enough energy gained by connecting Hydrogen -> Oxygen no matter what process you come up with.
Unless we find a way to fuse hydrogen together, hydrogen is a dead end and always has been.
