MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

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. Due to its size, any SCR system will likely need to be housed in the aircraft body, potentially making it most suitable for future hybrid- or turbo-electric aircraft designs.

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.

EPA releases national assessment of strategies to reduce air pollution at ports

Green Car Congress

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.

Eaton introduces set of products to reduce vapor emissions during refueling; LEV III regulations

Green Car Congress

Power management company Eaton has introduced a complete suite of solutions from its Vehicle Group to reduce vapor emissions produced during the refueling of gasoline-powered vehicles. This leakage occurs in all gasoline-powered vehicles, including passenger cars and an increasing number of small- and mid-sized commercial vehicles.

Why Schools Should Electrify Their Bus Fleets

Blink Charging

While it’s obvious that the internal combustion engine vehicles are polluting the air outside the buses, what you may not know is that numerous studies show that the pollution from the burning diesel regularly makes its way into the buses. The more vehicles that switch to running on electricity, the better.

California ARB moves forward with climate and air quality actions

Green Car Congress

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. emissions by more than 20%.
