The U.S Department of Energy (DOE) Bioenergy Technologies Office (BETO), in partnership with the Algae Foundation and NREL, has announced the grand champion and top four winning teams of the 2023 to 2025 DOE AlgaePrize Competition.

The AlgaePrize challenges students to think like bioeconomy professionals by developing novel solutions to challenges associated with gigaton-scale algae commercialization. The AlgaePrize Competition supports DOE’s effort to expand the domestic supply of an affordable and reliable energy resource.

AlgaePrize 2023 to 2025 teams included competitors from high schools, colleges, and universities across the United States who had the opportunity to gain real-world science, technology, engineering, and mathematics experience. The teams developed innovative solutions for algae production, processing, and new product development to lower the costs of producing algal biofuels and bioproducts. 

During the AlgaePrize Competition weekend on July 18 to 20, 2025, 13 finalist teams showcased their projects to a panel of judges at NREL in Golden, Colorado. 

Team Parachlorella Plastic Pals of University of California, San Diego in La Jolla, California, won this year’s competition and received a total of $25,000 in prize money. The team aimed to make biodegradable plastic (TPU) from algae, focusing on three key steps: growing the algae, turning its oil into useful ingredients, and creating and testing the final plastic products.

Four other teams were named top finalists, and each received $10,000 in prize money: 

BETO supports research and development to lower the costs of producing algal biofuels and bioproducts. The AlgaePrize competition is part of DOE’s American-Made Program, a national energy innovation ecosystem that connects competitors with experts, mentors, incubators, and investors to help develop products, secure funding, and bring innovations to market.
