We don't have to guess at the California electricity mix.
https://www.energy.ca.gov/almanac/electricity_data/total_system_power.html
(rounding to nearest percent for simplicity)
29% from renewables other than large hydro
15% from large hydro
9% from nuclear (not renewable, but reasonably low emissions impact from
an existing plant - final disposition of spent fuel still to be solved)
4% from coal
34% from natural gas (fossil)
9% unidentified
That's what shows up on the grid. It does not include those producing
off-grid, or generating for in-house use (e.g. household PV used behind
the meter).
Greener grid means greener EV use.
As for using hydrogen as a transportation fuel for light vehicles in
typical missions (commuting, errand running, occasional longer trips), I
looked into this early in this century, and kept some track since.
Things have not changed much on the technology side in the intervening
period for hydrogen vehicles, other than using bigger storage at higher
pressure.

California uses mostly hydro at night.? There are natural gas plants for high
demand.? I think that is how it works or should work.? Lawrence Rhodes
