UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

The levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles. These emissions are independent of the vehicle energy/propulsion system and therefore applicable to all road vehicle types including those with battery-electric powertrains. Cliff et al.

San José International deploys 10 Proterra electric buses in airport fleet

Green Car Congress

Mineta San José International Airport’s (SJC) has deployed a fleet of 10 Proterra battery-electric buses that will transport passengers and their luggage between SJC’s parking lots, rental car center, and terminals. The electric bus fleet is anticipated to reduce ozone emissions by 1.1

Toyota Central R&D Labs develops new ferrihydrite material that effectively removes ozone from air

Green Car Congress

(Japan) report in the journal Angewandte Chemie the development of a mesoporous two-line ferrihydrite (2LFh)—ferrihydrite is a widespread mineral composed of iron, oxygen, and water—that could lead to a new generation of ozone filters in electrostatic devices and aircraft applications. removal; it showed about 95 % O 3.

Using Ozone-Generated Bubbles to Remove Oil Sheen and Contaminants from Water

Green Car Congress

A University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. The ozone in the bubble attacks certain pollutants because it is a strong oxidant.

Pennsylvania DEP awards nearly $517,000 in clean diesel grants

Green Car Congress

The Pennsylvania Department of Environmental Protection (PA DEP) awarded $516,637 in clean diesel grants to four organizations. The clean diesel program’s goal is to improve air quality by decreasing emissions from diesel-powered transit bus and school bus fleets. Jennings Transportation Corp.:

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.

Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

Researchers from Northwestern University and Princeton University have explored the impact on US air quality from an aggressive conversion of internal combustion vehicles to battery-powered electric vehicles (EVs). coal, oil, natural gas, and biomass). Locations with clean energy sources, however, saw reductions. Schnell et al.
