To comply with the mandate to increase the use of alternative fuels, the Coast Guard has enlisted the help of Oak Ridge National Laboratory researchers with expertise in fuels and engines. "The Coast Guard has decided to use biobutanol rather than ethanol to mix with gasoline in their smaller craft, and biodiesel rather than petroleum diesel in their larger engines," said Tim Theiss, group leader of the Fuels, and Engines and Emissions Research Group Center. During the three-year project, researchers will focus on a number of tasks, including determining the maximum acceptable level of these renewable fuels with the marine engines and infrastructure necessary to operate in a saltwater environment. Since 1790, the Coast Guard has safeguarded America's maritime interests and the environment.
