Commercializing the green substance was the main event at the 5th Annual Algae Biomass Summit in Minneapolis lasting from Monday to Thursday.
Over 800 people attended the summit including 80 exhibitors which was double the number of last year's account, according to Minnesota Public Radio News.
Algae as an alternative fuel to petroleum was the key topic at the summit which was hosted by the Algal Biomass Organization.
"We are on the verge of breaking out on a global scale, not just here in the U.S.," Mark Allen, the president of the organization, said to Star Tribune.
The University of Minnesota facility in Rosemount has been researching on algae fuel but director of the University's Initiative for Renewable Energy and the Environment John Sheehan said to Star Tribune to not expected anything soon.
"High-volume production is not going to be possible for at least five years and probably longer," Sheehan.
