This report describes the results of an analysis tracing the technological influence of algae research funded by the U.S. Department of Energy (DOE)’s Bioenergy Technologies Office (BETO) and its precursor programs, as well as algae research funded by other offices in DOE. 74 algae patents are confirmed to be associated with BETO funding (53 U.S. patents, 6 EPO patents, and 15 WIPO patents). The study finds that Algae research funded by BETO, and by DOE in general, has had a significant influence on subsequent developments, both within and beyond algae technology. This influence can be seen upon innovations associated with the leading algae organizations. It can also be traced in other technologies, notably waste water treatment, power generation and carbon dioxide sequestration.
