Replying to myself. I just read the article. The gray/blue/green H2 fuel costs in the article do not reflect current U.S. fuel costs.
Gray is $8-10 for liquid delivery. This equates to a little over $1 per mile, which - compared to a CNG bus - is double the operating cost (and about 4x more than a battery electric bus per mile... just for fuel/electricity). And yeah, as I mentioned previously, capital costs will be like 1.3x of battery electric.
That said, there are lots of novel ideas out there for creating H2 fuel! Forest waste (with supposedly all carbon captured), methane pyrolysis (with carbon bricks as an output). The promises never end.
