Gas Hybrid Ozone Pollution

At cruising altitude, airplanes emit a steady stream of NO x into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. We quantify the effects of these trade-offs in terms of emissions reduction and fuel burn increase using representative engine cycle models provided by a major aero-gas turbine manufacturer.

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.

A new report from the US Environmental Protection Agency (EPA) finds that air pollution at US ports can be reduced significantly at all port types and sizes through a variety of strategies and cleaner technologies. In 2030, adding plug-in hybrid electric vehicles to these fleets could yield even more NO x and PM 2.5 Click to enlarge.

This problem is even more pronounced in hybrid-electric vehicles, which require special measures to address evaporative emissions as the gas engine only operates intermittently, creating the need to store pressurized fuel vapor. A Fuel Tank Isolation Valve is offered for use in hybrid electric vehicles.

In the release, Colorado clarifies that it includes battery-electric, plug-in hybrid electric and fuel cell electric as what it refers to as zero-emission options. The state has also said that it’s aiming to get one million zero-emission vehicles on its roads by 2030, along with its plan to eliminate greenhouse gas pollution entirely by 2050.

CARB also adopted a new plan to curb destructive “super pollutants” including black carbon, fluorinated gases and methane. The plan, California’s Short-lived Climate Pollutant Reduction Strategy, maps out the route to more rapid greenhouse gas reductions by clamping down on these super pollutants.
