This report describes the results of an analysis tracing the technological influence of hydrogen and fuel cell research funded by the Hydrogen and Fuel Cell Technologies Office (HFTO) in the U.S. Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy (EERE) and its precursor programs – as well as hydrogen and fuel cell research funded by other offices in DOE. The report covers three distinct technologies – fuel cells, hydrogen production, and hydrogen storage. These are considered to be separate technologies.
- 906 fuel cell patents are confirmed to be associated with HFTO funding (571 U.S. patents, 154 EPO patents, and 181 WIPO patents).
- 609 hydrogen production patents are confirmed to be associated with HFTO funding (380 U.S. patents, 117 EPO patents, and 112 WIPO patents).
- 224 hydrogen storage patents are confirmed to be associated with HFTO funding (143 U.S. patents, 37 EPO patents, and 44 WIPO patents).
