DOE: Life cycle GHG emissions for 2020 electric small SUV were half those of a conventional gasoline small SUV

Green Car Congress

Using current technologies, all evaluated biofuel, battery electric, and hydrogen fuel cell vehicle pathways offer significant C2G GHG emissions reduction compared to the current gasoline internal combustion engine vehicle. When fueled by hydrogen produced from landfill gas, the total dropped to 117 g CO 2 e/mi.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. —Curran et al.
