T&E: tests show cars powered by electrofuels emit high levels of criteria pollutants

Green Car Congress

E-fuels are made by combining green hydrogen with CO 2 to produce liquid fuel that can be similar to gasoline or diesel used in conventional engines (as well as kerosene used in aviation). The ethanol and e-fuel would separate out similarly to oil and water. The emissions were compared to the standard E10 EU gasoline.

Researchers develop large-scale, economical method to extract hydrogen from oil sands and oil fields

Green Car Congress

Canadian researchers have developed a large-scale economical method to extract hydrogen from oil sands (natural bitumen) and oil fields. The process can extract hydrogen from existing oil sands reservoirs, with huge existing supplies found in Canada and Venezuela. Proton Technologies is commercializing the process.

New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

The tailpipe real-world emissions were measured across four gasoline mid-sized sports utility vehicles from 2019 and 2020 model years, driven on a mix of urban and motorway routes. As testament to the filtration efficiency of the latest gasoline particulate filters (GPFs), tailpipe mass emissions are now as low as 0.02

Study shows two-stroke scooters dominant source of air pollution in many cities; asymmetric polluters

Green Car Congress

A study by European researchers has found that two-stroke (2S) scooters, although constituting a small fraction of the fleet, can dominate urban vehicular pollution through organic aerosol and aromatic emission factors up to thousands of times higher than from other vehicle classes.
