Questions Regarding Funding Opportunity Announcements

Please contact the email address for questions regarding Funding Opportunity Announcements. Upon the issuance of a FOA, only the Contracting Officer may communicate with Applicants. ARPA-E personnel and our support contractors are prohibited from communicating (in writing or otherwise) with Applicants regarding the FOA. This “quiet period” remains in effect until ARPA-E’s public announcement of its project selections.

ARPA-E will not pre-assess an Applicant’s proposal. Prospective Applicants must review the technical requirements of the FOA and independently determine whether their proposed concept warrants a submission.

DE-FOA-0002213: Request for Information (RFI): Biotechnologies to Ensure a Robust Mineral Supply Chain for Clean Energy

ARPA-E is interested in surveying bio-based ideas across the entire supply chain of critical materials and other metals (Ni, Cu), including exploration, mining, extraction, processing, refining and recycling/recovery of such materials. ARPA-E requests responses focusing on the feedstock supply for successfully meeting the domestic demand, economic feasibility and environmental sustainability of critical materials.

Please carefully review the REQUEST FOR INFORMATION GUIDELINES below. Please note, in particular, that the information you provide will be used by ARPA-E solely for program planning, without attribution. THIS IS A REQUEST FOR INFORMATION ONLY. THIS NOTICE DOES NOT CONSTITUTE A FUNDING OPPORTUNITY ANNOUNCEMENT (FOA). NO FOA EXISTS AT THIS TIME.
