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. SCR systems would reduce NO x emissions at the cost of increased aircraft weight and specific fuel consumption due to the pressure drop in the core stream induced by the catalyst.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

NO x is a precursor for both ground level ozone and secondary PM 2.5 It is important to state that there are several technology paths to achieve these levels of emissions, and some of them can simultaneously lower greenhouse gas emissions, such that the NO x reductions do not compete with the CO 2 reductions.

Why Electric Buses Are the Healthy School Choice

Blink Charging

Vehicle fleets across the United States are transitioning from internal combustion engine (ICE) to electric vehicles, and that includes school bus fleets. Electric school buses have no tailpipe emissions, so students are not directly exposed to harmful vehicle fumes when on or near the bus.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

However, since the cost of the hydrous ethanol is significantly lower, hydrous ethanol will provide a lower cost per mile travelled, assuming the processing cost savings is passed on to the consumer. Current Legal Requirement for Use of Anhydrous Ethanol in the United States. 40 CFR § 80.27 Pursuant to 40 CFR § 80.27(a)(2):
