Mineral Recovery Phase II - Geothermal Concepts And Approaches To Validate Extraction

archived

The purpose of this action is to notify potential applicants that a modification to this FOA has been issued. Please use the link below to access Modification 0001 in EERE eXCHANGE. The intent of this Funding Opportunity Announcement (FOA) is to promote the advancement of geothermal energy conversion processes by validating technologies capable of providing a secondary income stream from the same geo-fluids. Methods for economically capturing, concentrating, and/or purifying valuable materials contained within geothermal brines represent an opportunity to both meet critical U.S. materials needs and broaden, as well as strengthen, the value-proposition of geothermal energy operations. Results from this work can enhance current applications, support planned development, and potentially open additional regions in the U.S. for economic utilization of geothermal energy. This FOA invites responses in two (2) general topic areas, outlined below. Collaboration among industry, national laboratories, and academic institutions is encouraged; teaming will be strongly considered during the application reviews. Applicants will also be encouraged to coordinate activities with the Department of Energy (DOE) Critical Materials Institute led by Ames Laboratory. Topic Area 1: Engineering Validation of Existing Extraction Technologies Responses to this Topic Area are to validate processes or procedures to recover these materials from geothermal fluids or produced waters. Proposals may include processes currently effective in other industries that may be transferable to high value/critical material/strategic materials extraction from geothermal fluids, or processes that already experimentally demonstrate effectiveness for material recovery. Topic Area 2: U.S. Regional or Nationwide Assessment of High Value Materials in U.S. Geothermal Fluids and Produced Fluids For the this Topic Area, the Geothermal Technologies Office (GTO) seeks approaches to economically and quickly build a public, U.S.-wide resource assessment of dissolved critical and high-value materials that may be site-specific, region-wide, or a national assessment. A successful application will demonstrate expertise in geologic regimes as well as sampling and analysis. The full Funding Opportunity Announcement (FOA) is posted on the EERE Exchange website at https://eere-exchange.energy.gov. Applications must be submitted through the EERE Exchange website to be considered for award. The applicant must first register and create an account on the EERE Exchange website. A User Guide for the EERE Exchange website can be found on the website https://eere-exchange.energy.gov/Manuals.aspx. Information on where to submit questions regarding the content of the announcement and where to submit questions regarding submission of applications is found in the full FOA posted on the EERE Exchange website.
