Student Makes Fuel From Algae
A Minnesota teen has discovered a way to power trucks and cars with algae

Sixteen-year-old Josh Wolf spends up to 40 hours each week in a portable garage behind his family’s home in Elk River, Minnesota. But he’s not working on cars. He’s making his own diesel fuel—the type of fuel used to power trucks, trains, buses, boats, farm and construction vehicles, and even some automobiles—from algae.
Inside the garage, Josh grows algae in a large trash container filled with water. Using parts he took from an old toy rocket launcher, he shocks the algae with low levels of electricity. This causes oil inside the algae to shoot out and float to the surface of the water. About 40 hours later, Josh skims the oil from the water and adds household chemicals to it to turn it into diesel fuel. He produces about one liter of diesel each day, which he sometimes uses to fuel his friends’ pickup trucks.
“Getting to see my spark of an idea be [turned] into great work has been one of the most [thrilling] experiences . . . in my life,” Josh told Scholastic News.
Some companies already make diesel fuel out of dried algae using machines that squeeze oil from it. But Josh uses live algae, which he keeps alive to produce fuel over and over. And while the companies’ method costs about $20 per gallon of diesel fuel, Josh estimates his method costs only about 3 cents per gallon (plus an additional 90 cents per gallon to clean it up.)
FUEL OF THE FUTURE
Before starting his algae project last year, Josh had perfected turning cooking oil into diesel fuel. His method will soon help power Elk River school buses. He is also working on making gasoline out of plastic shopping bags, which are made from petroleum. So far he’s gotten a lawnmower to run using the product that resulted from this latest project.
But it’s Josh’s algae project that has gotten the most attention. Josh was named one of seven finalists in the 2011 International Algae Competition, the only high school student of the group. He gives presentations about his work at events. And he has a lawyer who is working on getting a patent for his oil production process, which would mean only he would have the right to use or sell it.
Josh is now looking for investors to help fund the project, which he’s been paying for with his allowance. He hopes to eventually sell his process to large fuel companies that can mass-produce the algae-based oil and turn it into various types of fuels, including gasoline and even jet engine fuel.
“I would like to see this running on a large-scale setup,” Josh says. “But only time will tell.”
