The U.S. Department of Energy (DOE) has announced a significant funding opportunity of up to $46 million aimed at accelerating research, development, and demonstration efforts in the field of clean hydrogen and fuel cell technologies. The funding will support projects that enhance the performance of technologies related to hydrogen production, infrastructure, and fuel cells, with a specific focus on deploying these technologies in impactful applications. This initiative is part of the Biden-Harris administration's comprehensive approach to advancing clean hydrogen technologies, as overseen by the Hydrogen Interagency Task Force. The funding opportunity, administered by DOE's Hydrogen and Fuel Cell Technologies Office (HFTO), will target key areas such as scaling up advanced photoelectrochemical hydrogen-production processes, improving materials for hydrogen infrastructure, developing components for fuel cells in heavy-duty transportation, and demonstrating domestic hydrogen fuel cell electric motorcoach buses. By investing in these critical technologies and facilitating their deployment, the initiative aims to drive decarbonization across challenging sectors like heavy-duty transportation and industrial processes. The projects supported by this funding opportunity will also play a significant role in reinforcing the long-term viability of DOE's Regional Clean Hydrogen Hubs (H2Hubs) and other commercial-scale hydrogen installations. The funding will be allocated to projects falling under specific topic areas, such as scaling up photoelectrochemical water splitting devices, developing high-performance materials for hydrogen service under extreme conditions, researching sustainable proton exchange membranes for heavy-duty transportation, and demonstrating domestic hydrogen fuel cell electric motorcoach buses. Overall, this funding opportunity represents a positive step towards advancing clean hydrogen technologies, driving decarbonization efforts, and realizing the vision of a sustainable and equitable economy outlined in the U.S. National Clean Hydrogen Strategy.
