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). A 10% blend was chosen due to existing fleet and EN228 standard compatibility. The ethanol and e-fuel would separate out similarly to oil and water.

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.

BNEF: Oil price plunge to have only moderate impact on low-carbon electricity development, but likely to slow EV growth

Green Car Congress

The collapse in world oil prices in the second half of 2014 will have only a moderate impact on the fast-developing low-carbon transition in the world electricity system, according to research firm Bloomberg New Energy Finance. Earlier Bloomberg New Energy Finance analysis showed that, with gasoline at $2.09 on 30 June to $61.60

EPA proposes stringent new emissions standards for light-, medium-, heavy-duty vehicles for MY 2027 and beyond

Green Car Congress

Together, the proposals would reduce oil imports by approximately 20 billion barrels. The proposal retains the proven regulatory design of previous EPA standards for light-duty vehicles, but leverages advances in clean car technology to further reduce both climate pollution and smog- and soot-forming emissions.

Small-displacement two-stroke H2 engine could address performance and emissions cost-effectively for recreational market; potential for Asian motor vehicle fleet

Green Car Congress

Comparison of brake thermal efficiency and specific fuel consumption at rated power (ICOMIA Mode 5), hydrogen vs. gasoline engines. It, or a scaled-up version, could also provide a solution for the Asian motor vehicle fleet, in which two-stroke engine vehicles constitute a major share—and contribute significantly to air pollution.

Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

The industrial processes behind crude oil refineries and the inner-workings of gas-powered combustion engines can emit PAHs, which can form into toxic air pollutants such as soot. They believe that the finding could one day lead to cleaner combustion engines.

Argonne updates GREET and AFLEET tools for transportation technologies analysis

Green Car Congress

Added biomass-derived high octane gasoline via indirect liquefaction and renewable gasoline/diesel pathways from fast pyrolysis. Updated the emission factors of criteria air pollutant (combustion and non-combustion emissions) for SMR hydrogen and petroleum fuels. Added new pathways for corn kernel fiber ethanol.
