grassahol
n.β Β«The latest research at Oklahoma State University includes work on a different approach that uses switchgrass to create whatβs called “grassahol.” The entire plant, diced into bits, is burned at high temperatures in a device called a “gasifier.” This produces carbon monoxide, carbon dioxide, and hydrogen gases that are “bubbled” through a bioreactor, where micro-organisms convert them into ethanol. As an engine fuel, itβs about 85 percent as efficient as gasoline.Β» ββYouβve Heard of Ethanol; Here Comes βGrassaholβ” by Ted Landphair in Stillwater, Oklahoma Voice of America Dec. 21, 2006.
