Request for Information - Gauging Investor Interest in the Development and Commercialization of Subsurface Energy Technologies

The U.S. Department of Energy’s Hydrocarbons and Geothermal Energy Office (HGEO) is issuing a Request for Information (RFI) to gauge private‑capital interest in developing and commercializing subsurface‑energy technologies across coal, oil & gas, and geothermal sectors. The RFI seeks feedback from investors, venture capital firms, financial institutions, as well as technology developers, incubators, and research organizations on topics such as modular LNG components, mid‑stream sensors, produced‑water treatment, advanced drilling, geothermal reservoir characterization, coal‑plant modernization, and related emissions‑control solutions. No funding is offered; responses are purely informational and must be submitted electronically by 5:00 PM ET on 5 Oct 2026, limited to 10 pages in Word format. The information will be used for DOE planning and potential public‑private partnership strategies, but the agency does not commit to future awards. • Target audience: investors, venture capital, SBICs, technology startups, research labs, and related stakeholders. • Scope: solicit interest, technical needs, financing structures, risk tolerance, and TRL expectations for a broad set of subsurface‑energy technologies. • Submission: email [email protected], 10‑page limit, 12‑pt font, 1‑in margins, ≤25 MB. • No cost sharing, no award, and no obligation for DOE to respond to individual submissions.
