There is no such thing as "Green hydrogen", other than the facade of oil companies that created that term to allay climate change fears. And we even have a term for this - Greenwashing.
> So called green hydrogen has its own problems. Yes, it is technically possible to use renewably-produced electricity to electrolyse water, to make hydrogen – but you need a huge amount of electricity to produce a small amount of hydrogen.
If we can improve the efficiency of electrolysis production of hydrogen, then I don't see how it's greenwashing if it's possible to produce hydrogen without carbon.
If you make ethanol from freely available hydrogen, you can convert the existing fleets (basically anything after like 2000 should be able to run ethanol with some hose and seal replacements). This is dramatically cheaper than telling the poor and middle class, "Let them by EVs (which cost a small mortgage)."

The 2023 Chevy Bolt has a list price of $26K before the subsidy. Tesla Model 3 is $43K before subsidy. The average price paid for a new car in 2022 was $50K. Of course no one is forcing the poor and middle class (or anyone else) to buy EVs. Most of them by used cars anyway, that market is definitely not mature yet, though the new subsidy can now be applied to used models.
Even before the price war which has just broken out most mainstream industry analysts were predicting upfront, nonsubsidized price parity of like EV and ICE models mid to late this decade. That's on top of the significantly lower fuel and maintenance costs and of course the subsidies.
