I must have blinked or maybe I'm blind. Could you please repeat your
citation for cases where hydrogen generation (from non fossil fuels)
currently is cleaner than grid electricity.

See the subject of the thread for the bottom line answer, though things are
never as simple as a one-liner. But I gave you my answer, and you didn’t want
to accept it.
I also gave you the reasons why, but you wanted sources, so there’s the table.
I really don’t use this table - it was just to give you the info you wanted. I
could pick and choose data pieces, but that wouldn’t be fair either.
Hydrogen *can* be cleaner, and actually is frequently.
For someone who wanted to jump into the deep data, something I learned recently
is that for those charging from the grid at night, the energy they are using is
virtually all non-renewable (fossil). And I’m told that most of it is from
fracked natural gas.(this is all California perspective - other areas use more
coal on the grid)
For those of you that are thinking that faced with this information, battery EV
are not worth pushing any more (haha), I’ll say that you are still wrong. BOTH
are still important, and needed. And that’s been my point from the beginning.

Mark,
Thanks for posting this. Maybe someone else can benefit from it but I really
don't know how to use this spreadsheet nor do I have the time to dedicate to
learning it. If you would be able to answer the fundamental question, which I
think can be done without reference to this spreadsheet, that would be most
helpful.

I’ll you interpret the the results.
I’ve seen a number of summary charts that various people have created, but you
seem to want detail, so here are the detailed results of the current GREET
model - California version:
CA GREET model 2.0 results

Note: I don’t think that CO2 numbers are total CO2 equivalent (check this), so
you might want to look at GHGs rather than CO2, if that’s the metric you want.
Then again, I don’t know those numbers are CO2 equivalent either.
Have fun.

Alright, Mark, then let's look at it from a point of view of emissions (CO2 in
particular). Do you have references showing that emissions from producing
hydrogen (from non fossil fuels) have less than emissions from producing
electricity for the same amount of traction energy?
