I'll add: while it may be true that hydrogen for fuel cells comes from
methane generated by anaerobic fermentation, that is irrelevant.
Why? Because, even with the enormous mountains of waste we produce, that
can only produce a small percentage of the hydrogen needed to power all
the vehicles in the country. It may look good on a small scale but
can't be done on a large scale.
Incidentally, that's a different case from buying RECs or using solar
panels to generate electricity to charge your EV. That model is
scalable.

Currently most hydrogen is produced by natural gas reforming which

But for auto fueling, that which is reformed is frequently made from
renewable methane, so *is* green.
But almost all methane comes form natgas, no? I realize it is possible
to make it from aneorbic fermentation, but almost none of that is in
the market, being made by micro producers for their own use. Methane is
a “stranded market,” not suitable for shipping long distances, so
“renewable methane” tends to be consumed right next to dairy farms,
feedlots, etc. where it is produced.
Disclosure: one of my clients is in the hydrogen industry.
Disclosure: I’ve studied this in some detail, and have made bio-methane
for cooking, which is most useful at low pressure — it takes as much
energy as is in the methane to compress it to the ~500 torr necessary
to have any driving range.
If you have some references, I’d love to see them!
