Obama Announces Steps to Boost Biofuels, Clean Coal; RFS2, BCAP, BIWG and Carbon Capture and Storage Task Force

Green Car Congress

It’s been said that the United States is the Saudi Arabia of coal—and that’s because, as I said, it’s one of our most abundant energy resources. Further, for the first time, EPA is setting volume standards for specific categories of renewable fuels including cellulosic, biomass-based diesel, and total advanced renewable fuels.

Study finds blending gasoline with GTL improves efficiency and lowers emissions in compression-ignition PPC mode

Green Car Congress

In our previous work, we evaluated the performance of two Fischer–Tropsch (FT) GTL diesel fuels with CNs of 52 and 72 in various combustion modes from high (i.e., While future GTL plant owners might take notice of aforementioned insights, producers of high CN GTL diesel must necessarily add low CN compounds in order to decrease the CN. …
