In Colorado, a study conducted by DOE’s National Renewable Energy Laboratory (NREL), found that the petroleum components of ethanol-blended gasoline become degraded and unfit for use in an engine long before the ethanol portion takes up enough water to cause phase separation in the fuel tank. “Phase separation” occurs when an excessive amount of water […]
A reader writes: I’d hoped that the biofuels crowd would have gotten beyond ethanol by now. The industry has made progress creating all kinds of specialty chemicals from renewable sources and more or less successfully brought them to market. There’s jet and diesel in commercial use whether or not they’re yet profitable. However they […]
In Washington, the Energy Information Agency says E10 accounts for more than 95% of the fuel consumed in motor vehicles with gasoline engines. The total volume of ethanol blended into motor fuels used in the United States has continued to increase since 2010, albeit at a declining rate of growth. Meanwhile, the use of ethanol-free […]
It’s not your Dad’s gasoline. In fact, it’s worse, says the Union of Concerned Scientists in a new report. But the good news is that alternatives, by contrast, are getting cleaner. In Washington, the Union of Concerned Scientists reports that the gas pumped by American motorists is 30 percent dirtier to extract and refine than […]
In Brazil, hydrous ethanol prices have jumped 7% on the week to an all-time high as drivers continue to prefer filling up with 100% ethanol rather than gasoline at the pump where recent increases in prices still make ethanol more attractive. Mills are also beginning to keep back volumes from the market to ensure supplies […]
In Texas, Root Fuels has started offering B50 and B100 at its gas station in Houston just six months after offering B20. One pump sells unleaded gasoline and B100 to two lanes while the other has a blender pump offering B20, B50 and B100, also selling to two lanes. The biodiesel he buys is RINless […]
What’s the best way to maximize the value for your transportation dollar — cost per mile, and in delivering CO2 emission reductions? If you guessed “all electric”, dial again. But if you opted for the little-understood world of “E85”, you’re in for a treat. Good value, isn’t that important to you? Many readers tell us […]
In Washington, retail gasoline prices from 2013 through the first quarter of 2015 were unaffected by prices for “RIN credits” (Renewable Identification Numbers) that are used to demonstrate compliance with the Renewable Fuel Standard (RFS), according to a new detailed statistical analysis conducted by Informa Economics, Inc. The study found that “Changes in prices of […]
In the US, ethanol production last week averaged 924,000 barrels per day, 38.81 million gallons daily, down 12,000 b/d from the week before and a 25 week low. The four-week average for ethanol production stood at 941,000 b/d for an annualized rate of 14.43 billion gallons. Gasoline demand for the week averaged 374.4 million gallons […]
In the US, ethanol production averaged 979,000 barrels per day for the week before last, up by 1000 b/d from the week before. The four-week average for ethanol production stood at 970,000 b/d for an annualized rate of 14.87 billion gallons. Gasoline demand for the week averaged 371.7 million gallons daily, little changed from last […]
