On September 8, 2017, the U.S. Department of Energy (DOE) selected an additional four Productivity Enhanced Algae and Toolkits (PEAK) projects to receive up to $8.8 million. The projects aim to develop high-impact tools and techniques that will increase the productivity of algae organisms to reduce the costs of producing algal biofuels and bioproducts. In total, DOE has awarded over $16 million in funding to the initiative.

The project winners include:

  • Colorado School of Mines, in partnership with Global Algae Innovations, Pacific Northwest National Laboratory, and Colorado State University, which will use advanced directed evolution approaches in combination with high-performance, custom-built, solar simulation bioreactors to improve the productivity of robust wild algal strains;
  • University of California, San Diego, which will work with Triton Health and Nutrition, Algenesis Materials, and Global Algae Innovations on the development of genetic tools, high-throughput screening methods, and breeding strategies for green algae and cyanobacteria, targeting robust production strains;
  • University of Toledo, in partnership with Montana State University and the University of North Carolina, which will cultivate microalgae in high-salinity and high-alkalinity media to achieve productivities without needing to add concentrated carbon dioxide, and deliver molecular toolkits, including metabolic modeling combined with targeted genome editing; and
  • Lawrence Livermore National Laboratory, which will ecologically engineer algae to encourage growth of bacteria that efficiently remineralize dissolved organic matter to improve carbon dioxide uptake and simultaneously remove excess oxygen.
