Greyrock, NREL study determines reduction in GHG and criteria pollutant emissions from using synthetic fuels produced from flare gas

Green Car Congress

A “well-to-wheel” life cycle assessment (LCA) by a team from synthetic fuels producer Greyrock ( earlier post ), and the National Renewable Energy Laboratory (NREL) has determined the potential reduction of greenhouse gases and criteria pollutant emissions from the use of synthetic fuels directly converted from flare gas.

UC Riverside team examines influence of mid-and high-level ethanol blends on pollution from GDI flex fuel vehicle

Green Car Congress

Their paper is published in the ACS journal Energy & Fuels. Regulated emissions for all test fuels over the cold-start and hot-start LA92 cycles. A fuel economy penalty was also observed for lower energy content E30 and E78 blends compared to both E10 fuels. The study found that higher ethanol blends—i.e.,

Study finds catalyzed gasoline particulate filters effective at reducing particulate and PAH emissions from GDI engines

Green Car Congress

The researchers assessed the gaseous, particulate, and genotoxic pollutants from two current technology gasoline direct injection vehicles when tested in their original configuration and with a catalyzed gasoline particulate filter (GPF). Their study is publishedin the ACS journal Environmental Science & Technology. Yang et al.

CMU study finds that coal retirement is needed for EVs to reduce air pollution

Green Car Congress

Electric vehicles charged in coal-heavy regions can create more human health and environmental damages from life cycle air emissions than gasoline vehicles, according to a new consequential life cycle analysis by researchers from Carnegie Mellon University. UC stands for uncontrolled charging and CC stands for controlled charging.
