Study finds PHEVs will reduce net emissions of CO2 and NOx; upward pressure on SO2

Green Car Congress

Net emissions resulting from the use of plug-in hybrid electric vehicles (PHEVs) depend on the efficiency of the conventional vehicle fleet; PHEV CD (all-electric, charge-depleting mode) efficiency; charging strategy; battery pack capacity; driving patterns; and generator mix used for charging.

They also note that large-scale production of synthetic fuels or hydrogen from coal or gas offers the potential for GHG emissions reduction—but only if CO 2 can be captured and stored. The hybridization option investigated brings an additional energy and GHG reduction of about 30% for gasoline and 20% for diesel hybrid vehicles.
