Ethanol and Ozone

Plugs and Cars

We need to prioritize clean electricity generation and plug-in battery cars to utilize that energy efficiently. ozone There are so many reasons ethanol shouldn't be priority #1 in America's quest for petroleum replacement. I blogged about this previously here. Yet another reason to think again about the ethanol craze in an article in today's LA Times.

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. In addition, the study, published in the IOP journal Environmental Research Letters , found that charging plug-in vehicles at night could slightly reduce, on average, ozone.

Modelling the Impact of PHEVs on Ozone in Denver

Green Car Congress

Denver represents an interesting case study for exploring potential PHEV impacts because it violates the federal air quality standard for ozone and because several large EGUs [electricity generating units] are located in or near the urbanized area. The ozone response to PHEV penetration was modeled under a wide range of meteorological conditions, as experienced during July 2006. Ozone concentration increases were modeled for small areas near central Denver.
