Univ of Toronto study details impacts of interaction between driving patterns and electricity generation for WTW energy use and GHG emissions for PHEVs

Green Car Congress

WTW GHG emissions of vehicles across driving patterns and PHEV charging scenarios. coal, hydro, natural gas) on well-to-wheel (WTW) energy use and greenhouse gas (GHG) emissions of plug-in hybrid electric vehicles (PHEVs). Driving patterns affect the WTW performance of PHEVs in two ways, they found. Click to enlarge.

Electric vs. Gasoline Cars: Uncovering the Real Climate Savior

The Truth About Cars

For instance, electricity generated from coal or natural gas is associated with higher carbon emissions, while renewable sources like wind or solar energy contribute negligible carbon pollution. However, the production of electricity for EV charging can result in carbon emissions, depending on the energy source.

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

In a new study published in the journal Applied Energy , Carnegie Mellon University (CMU) researchers found that controlled charging of plug-in hybrid electric vehicles (PHEVs) reduces the costs of integrating the vehicles into an electricity system by 54–73% depending on the scenario.

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.

CMU study finds that HEVs and PHEVs with small battery packs offer more emissions and oil displacement benefits per dollar spent than large pack PHEVs and BEVs; policy implications

Green Car Congress

Strategies to promote adoption of hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) with small battery packs offer more social benefits (i.e., We find that, in the base case, plug-in vehicles (PHEVs and BEVs) may produce more damage on average than today’s HEVs.

National Research Council Report on Americas Energy Future Highlights Vehicle Efficiency Technologies, Conversion of Biomass and Coal-to-Liquids Fuels, and Electrifying the Light Duty Fleet with PHEVs, BEVs and FCVs

Green Car Congress

Developing technologies for the conversion of biomass and coal-to-liquid fuels. By 2035, cellulosic ethanol and/or coal-and-biomass-to-liquid (CBTL) fuels with carbon capture and storage could replace about 15% of current fuel consumption in the transportation sector (1.7–2.5 emissions, according to the report.
