French Government to award up to €10,000 to drivers to switch from older diesels to plug-ins

Green Car Congress

French Minister of Ecology, Sustainable Development and Energy Ségolène Royal announced that the government would award up to €10,000 (US$11,315) to individuals to switch from older diesel cars (13 years and older) to plug-in hybrids or battery-electric vehicles. The conversion premium is for individuals. Conversion bonus.

Forecast: Global Natural Gas Vehicle Fleet to Reach 17 Million by 2015

Green Car Congress

The cleantech market intelligence firm forecasts that the number of NGVs on the road worldwide will grow to 17 million vehicles by 2015, up from 9.7 to reach just more than 3 million vehicles (including conversions) by 2015. NGVs have substantially lower GHG, CO 2 , and NO x than gasoline or diesel. between 2008 and 2015.

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

Green Car Congress

A Greyrock Flare Gas-to-Fuels conversion process at an Ohio oil well was used as the base case for this LCA. The liquid fuel produced directly from methane and other wellhead gases (associated gas) that would otherwise be burned or flared gas primarily consists of premium synthetic diesel with a small amount of synthetic gasoline.

New nanostructured earth abundant metal catalysts rival platinum on a weight basis; diesel emissions treatment

Green Car Congress

A development in catalysis research by academics at the Universities of St Andrews and Newcastle could lead to new systems to treat diesel emissions. Catalysts are typically metallic nanoparticles—often platinum group metals—that are finely deposited upon a substrate. This is referred to as “chemistry at a point”.

Neste Oil de-emphasizing microbial oil R&D for renewable diesel; seeking other uses for cellulosic biomass

Green Car Congress

Neste Oil produces NExBTL diesel (and its other renewable fuel cousins such as jet fuel) by using a proprietary process to hydrogenate vegetable oil or animal fat feedstocks. The result is a tailored drop-in fuel; with several major NExBTL refineries worldwide, Neste is currently the leading producer of renewable diesel.

ORNL team discovers mechanism behind direct ethanol-to-hydrocarbon conversion; implications for energy efficiency and cost of upgrading

Green Car Congress

Uncovering the mechanism behind the reaction helps support the potential economic viability of ORNL’s own direct biofuel-to-hydrocarbon conversion approach. This has renewed interest in the conversion of ethanol to hydrocarbon blend-stock and other industrial chemicals. The mechanism of ethanol conversion is still being debated. …
