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. 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.

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.

Colorado approves goal to make 82% of car sales electric by 2032

Teslarati

Colorado has voted to approve a new standard on the adoption of electric vehicles (EVs), with an additional goal set for 2032 and new guidance for increasing EV sales beginning in 2027. Notably, the release says that the standard does not prohibit the sale or use of non-electric vehicles with internal combustion engines (ICEs).

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

Green Car Congress

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.
