Laramie, WY – A major reason ethanol isn't widely used as fuel is that the cost is too high - and one University of Wyoming researcher is hoping to change that.
Engineering Professor Patrick Johnson has received nearly half a million dollars to look for a cheaper way to make ethanol. He's focusing on enzymes, a very expensive ingredient that helps turn corn into fuel.
Johnson's strategy is to recycle those enzymes to lower costs.
The grant comes from the US Department of Transportation through the Sun Grant Initiative, a plan funded by the US Congress to diversify the nation's energy resources.
