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

To meet a goal set by the US Environmental Protection Agency’s Renewable Fuels Standard to use 36 billion gallons of biofuels each year—mostly ethanol—the nation must expand its infrastructure for transporting and storing ethanol. Ethanol, however, is known for triggering stress corrosion cracking of steel. Researchers investigated the mechanism of how ethanol triggers stress corrosion cracking, reported in Corrosion journal, along with ways to circumvent this issue to prevent ethanol-related corrosion issues.
