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.
