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. The results are less clear in Dallas and Houston.

However, notes the MIT team, the engine and measurement conditions of the RON and MON tests do not represent real world operating conditions. reduction by then in the baseline case (i.e.,

Sentoff, suggested that based on these results, more positive forecasts for future petroleum and corresponding CO 2 emissions savings from increased hybridization of the passenger vehicle fleet may be warranted. PHEVs and BEVs) comprise a larger portion of the on-road fleet. The duo, Britt A. Holmén and Karen M.

From our studies of vehicle electrification, we have concluded that PHEVs offer the most viable path toward powering more vehicle miles with electricity. However, BEVs do appeal because their propulsion system is simpler than an ICE, and they do not dilute their “electric miles” with “gasoline miles,” as does a PHEV.
