Texas study finds PHEV use could increase ozone at night, decrease ozone during the day

Green Car Congress

A study by researchers at the University of Texas found that in general, use of plug-in hybrid electric vehicles (PHEVs) can lead to an increase in ozone during nighttime hours (due to decreased scavenging from both vehicles and EGU stacks) and a decrease in ozone during daytime hours.

Life cycle analysis of three battery chemistries for PHEVs and BEVs; environmental impacts higher than expected

Green Car Congress

Researchers from the Norwegian University of Science and Technology (NTNU) have performed life cycle assessments (LCA) of three batteries for plug-in hybrid (PHEV) and full performance battery electric (BEV) vehicles. Click to enlarge. They also found higher life cycle global warming emissions than have been previously reported.

Study Highlights the Importance of Considering Climate Effects of Non-CO2 Emissions from Transport in Mitigation Strategies and Policies

Green Car Congress

The on-road transportation (ORT) and power generation (PG) sectors are major contributors to CO 2 emissions and a host of short-lived radiatively-active air pollutants, including tropospheric ozone and fine aerosol particles, that exert complex influences on global climate.

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. Ozone concentration increases were modeled for small areas near central Denver.

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

Green Car Congress

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. Results by battery chemistry and stage for PHEV batteries.
