Microorganisms can be turned into biodiesel, and the cost is going down.
ST. PAUL, Minn. - The 16 big flasks of bubbling bright green liquids in Roger Ruan's lab at the University of Minnesota are part of a new boom in renewable energy research.
Driven by renewed investment as oil prices push $100 a barrel, Ruan and scores of scientists around the world are racing to turn algae into a commercially viable energy source.
Some varieties of algae are as much as 50 percent oil, and that oil can be converted into biodiesel or jet fuel. The biggest challenge is slashing the cost of production, which by one Defense Department estimate is running more than $20 a gallon.
"If you can get algae oils down below $2 a gallon, then you'll be where you need to be. And there's a lot of people who think you can," said Jennifer Holmgren, director of the renewable fuels unit of UOP LLC, an energy subsidiary of Honeywell International Inc.
