Report: Ozone levels drop 20 percent with switch from ethanol to gasoline

A Northwestern University study by an economist and a chemist reports that when fuel prices drove residents of São Paulo, Brazil, to mostly switch from ethanol to gasoline in their flexible-fuel vehicles, local ozone levels dropped 20 percent. At the same time, nitric oxide and carbon monoxide concentrations tended to go up.

How to make ethanol without corn or other plants

Stanford University scientists have found a new, highly efficient way to produce liquid ethanol from carbon monoxide gas. This promising discovery could provide an eco-friendly alternative to conventional ethanol production from corn and other crops, say the scientists. Their results are published in the April 9 advanced online edition of the journal Nature.

Report: US confused about ethanol

There’s even more turmoil than usual in the U.S. biofuels policy realm, with lawsuits, demands for criminal investigations, leaked documents and threats flying all over the place.

Claim: Ethanol not a major factor in reducing gas prices

If you have stopped at a gas station recently, there is a good chance your auto has consumed fuel with ethanol blended into it. Yet the price of gasoline is not substantially affected by the volume of its ethanol content, according to a paper co-authored by an MIT economist.

Solving ethanol's corrosion problem may help speed the biofuel to market

If we're to meet a goal set by the U.S. Environmental Protection Agency's Renewable Fuels Standard to use 36 billion gallons per year of biofuels—mostly ethanol—the nation must expand its infrastructure for transporting and storing ethanol. Currently, ethanol is transported via trucks, trains, and barges. For the large volumes required in the future, transportation by pipeline is considered to be the most efficient method to get it to customers.

Will Butanol end up in your gas tank?

New research could speed the nascent switch from ethanol to butanol.
