DEPARTMENT OF ENERGY Expression of Interest—DOE's Office of Environmental Management (DOE-EM) Critical Minerals and Materials Inventory. AGENCY: Office of Environmental Management, Department of Energy. ACTION: Expression of Interest (EOI). SUMMARY: The U.S. Department of Energy (DOE) Office of Environmental Management (EM) publishes the following questions regarding potential collaboration with interested parties for the reuse of its critical and rare earth minerals and materials. The goal is to ensure surplus critical minerals and materials within the DOE inventory are repurposed to bolster and diversify the U.S. supply chain. This will support domestic scientific, manufacturing, and energy needs. A list of materials and minerals in DOE's inventory is supplied as an attachment. Respondents should note that industry partners would be responsible for the subsequent extraction or reprocessing of the material. THIS IS AN EXPRESSION OF INTEREST ONLY. THIS NOTICE DOES NOT CONSTITUTE A NOTICE OF FUNDING OPPORTUNITY (NOFO). A NOFO DOES NOT EXIST AT THIS TIME. DOE will not provide funding or compensation for any information submitted in response to this EOI. This EOI is not seeking or accepting applications, and a response to this EOI will not be viewed as a binding commitment to develop or pursue the ideas discussed. No material submitted for review will be returned. DATES: Responses to the EOI must be received no later than November 2, 2026. A virtual Industry Day will be held on September 30, 2026. For questions and a link to attend, please email Rob Seifert, robert.seifert@em.doe.gov. ADDRESSES: Interested parties are to submit comments electronically to robert.seifert@em.doe.gov with the subject line “EM Critical Minerals Inventory” no later than November 2, 2026. All responses must be submitted as a Microsoft Word document (.doc/.docx) of no more than five (5) pages in length, with black, Times New Roman, 12-point font, and 1-inch margins as an attachment to an email.
