Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. (In In this paper PHEV refers solely to the long-range PHEV of 60 miles (100 km) electric-only range.) It is much more than that.

Abt life-cycle analysis of different Li-ion chemistries for PHEVs and EVs identifies opportunities for improving environmental profile of batteries

Green Car Congress

Source: “Application of LCA to Nanoscale Technology”. life-cycle study of three Li-ion battery chemistries for plug-in hybrid (PHEV) and battery-electric (BEV) vehicles generated a number of findings and identified opportunities for improving the environmental profile of Li-ion batteries for use in plug-in and electric vehicles.

Modelling the Impact of PHEVs on Ozone in Denver

Green Car Congress

Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybrid electric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. Brinkman et al. VOC emissions would have been reduced by 57 tpd.

However, the report concludes, initiating deployment of these technologies is urgent; actions taken—or not taken—between now and 2020 to develop and demonstrate several key technologies will largely determine the nation’s energy options for many decades to come. emissions, according to the report.

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. Michalek et al. are also substantial.

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

This is especially important for assessing the GHG emissions of PHEVs. For battery EVs, the GHG emissions for “fuel/electricity” production are dominated by the coal and natural gas used in electricity generation. BEVs powered by renewable electricity and FCEVs fueled by green hydrogen are the only two technology pathways that qualify.

MIT, Ford researchers find lightweight conventional vehicles could have lower lifecycle GHG impact than EVs depending upon location

Green Car Congress

Their paper is published in the ACS journal Environmental Science & Technology. Regional differences in climate, electric grid burdens, and driving patterns compound to produce significant regional heterogeneity in the GHG benefits of electrification. We show that lightweighting further accentuates these regional differences.
