I'm happy to see progress being made toward the reduction of fossil fuel use in transportation, with multiple technologies.
I Googled, "how is industrial hydrogen produced?"
The answer (from Wikipedia):
Hydrogen production is the family of industrial methods for generating hydrogen gas. There are four main sources for the commercial production of hydrogen: natural gas, oil, coal, and electrolysis of water; which account for 48%, 30%, 18% and 4% of the world's hydrogen production respectively.[1] Fossil fuels are the dominant source of industrial hydrogen.[2] As of 2020, the majority of hydrogen (~95%) is produced by steam reforming of natural gas and other light hydrocarbons, partial oxidation of heavier hydrocarbons, and coal gasification.[3][4] Other methods of hydrogen production include biomass gasification and methane pyrolysis. Methane pyrolysis and water electrolysis can use any source of electricity including renewable energy.
So if I read that correctly, 96% of industrial hydrogen is currently produced from fossil fuels (Natural Gas, Oil, & Coal). Long way to go it seems, to make Hydrogen a truly green energy source, available on a large scale. And what happens to to Carbon atoms when the Hydrogen is liberated from natural gas or coal?
Currently, roughly 40% of Colorado's electrical grid is energy produced from renewables like wind and solar, the remaining 60% is from fossil fuels (mostly coal, I think). I hope this will improve over time, but we do need to keep in mind how the fuel for the 'green' transportation is produced - that needs to be green technology as well, or its not as big a win as we might think.
