Algae biofuel can help meet world energy demand, researchers say……

(Phys.org) —Microalgae-based biofuel not only has the potential to quench a sizable chunk of the world’s energy demands, say Utah State University researchers. It’s a potential game-changer.

According to Global Assessment, Algae Good Candidate for Biofuel

“Our results were much more conservative than those found in the current literature,” Quinn says. “Even so, the numbers are impressive.”

Algae, he says, yields about 2,500 gallons of biofuel per acre per year. In contrast, soybeans yield approximately 48 gallons; corn about 18 gallons.

“In addition, soybeans and corn require arable land that detracts from food production,” Quinn says. “Microalgae can be produced in non-arable areas unsuitable for agriculture.”

The researchers estimate untillable land in Brazil, Canada, China and the U.S. could be used to produce enough algal biofuel to supplement more than 30 percent of those countries’ fuel consumption.

“That’s an impressive percentage from renewable energy,” Moody says. “Our findings will help to justify the investment in technology development and infrastructure to make algal biofuel a viable fuel source.”
