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.

This study builds on the 2007 Environmental Assessment of Plug-in Hybrid Electric Vehicles by EPRI and NRDC ( earlier post ), which showed that plug-in hybrid electric vehicles could contribute to reductions in national greenhouse gas emissions, while also leading to improved air quality.

The basic question addressed, which appears on the study homepage (epri-reports.org) is this: How would air quality and greenhouse gas emissions be affected if significant numbers of Americans drove cars that were fueled by the power grid? And the grid is getting cleaner and more renewable every year. billion metric tons.

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.

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. million vehicles and would have increased by 3 tpd from power plants.

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.
