DE-FOA-0002786: Request for Information (RFI) on Stimulating Geochemical Reactions in the Subsurface for in-situ Generation of Hydrogen and Helium Production

The purpose of this RFI is to solicit input for a potential future ARPA-E research program focused on enabling technical advances which could lead to subsurface chemical reactors and gas separations. ARPA-E is seeking information to test the hypothesis that the subsurface can be used as a reactive environment to produce hydrogen at $1/kg, per DOE’s Hydrogen Shot target[1], and helium with no carbon emissions.


No material submitted for review will be returned and there will be no formal or informal debriefing concerning the review of any submitted material. ARPA-E may contact respondents to request clarification or seek additional information relevant to this RFI. All responses provided will be considered, but ARPA-E will not respond to individual submissions or publish publicly a compendium of responses. Respondents shall not include any information in the response to this RFI that could be considered proprietary or confidential.

Responses to this RFI should be submitted in PDF format to the email address by 5:00 PM Eastern Time on July 11, 2022. Emails should conform to the following guidelines:

  • Please insert “Response to Hydrogen-Helium Geochemistry - <your organization name>” in the subject line of your email.
  • In the body of your email, include your name, title, organization, type of organization (e.g. university, non-governmental organization, small business, large business, federally funded research and development center (FFRDC), government-owned/government-operated (GOGO), etc.), email address, telephone number, and area of expertise.
  • Responses to this RFI are limited to no more than 10 pages in length (12-point font size).
  • Respondents are strongly encouraged to include preliminary results, data, and figures that describe their potential processes.
