The U.S. Department of Energy (DOE)’s Hydrocarbons and Geothermal Energy Office (HGEO) is issuing this Request for Information (RFI) to notify parties of its potential interest in connecting private capital/ public-private partnership programs to industry opportunities. This initiative provides HGEO’s technical expertise across the Office of Subsurface Energy’s three core program areas: Coal, Oil & Gas, and Geothermal. Ultimately, the goal is to use HGEO’s research and development (R&D) capabilities to support industry and capital.Through this RFI, DOE requests input from all stakeholders, particularly the financial sector, to gauge investor interest in the development and commercialization of subsurface-energy technologies. This is solely a request for information and not a Notice of Funding Opportunity (NOFO). DOE’s HGEO is not accepting applications for funding at this time.
