Forget the need for the Keystone XL pipeline or Diablo Canyon’s nuclear reactors. San Luis Obispo’s very own Cal Poly is paving the way for a green energy future thanks to some hearty microorganisms and the contents of a toilet bowl. A research team dubbed the Algae Technology Group (ATG) has recently been awarded a $1.3 million grant by the Department of Energy to develop biofuels made from municipal wastewater and algae. The tiny plants not only help to clean water efficiently and inexpensively, but also produce energy and sequester carbon. Local governments will soon have a new method to purify water and can even sell to algae feedstock to refineries for a little extra revenue.
The ATG began back in 2006 and has since been working with faculty and students to research water reclamation and energy production. Their current project will use nine large “raceway” style ponds that cover about half an acre at the San Luis Obispo Water Reclamation Facility on Prado Road. Algae will grow in the ponds, using little inputs other than wastewater and sunlight. Some electricity is needed to circulate the water and run related equipment, but engineers believe that much of that energy could come from renewable sources in the future.
While still an emerging technology, the ATG estimates that with only ten percent of the market share in California, algae biofuel could reduce rate payers’ bills by an accumulated $240 million a year. The U.S. Department of Energy predicts that the nation could produce 21 billion gallons of algae biofuel annually. So, between dirty and expensive fossil fuels or cheap energy made from microscopic plants, which alternative would you choose?
