DE-FOA-0002469: Request for Information (RFI) on CO2 Mineralization to Enhance the Extraction of Energy-Relevant and Commodity Minerals

The purpose of this RFI is to solicit input for a potential future ARPA-E research program focused on novel, potentially transformative technical opportunities and approaches to liberate minerals relevant to our energy infrastructure while concurrently mineralizing carbon dioxide.

ARPA-E requests responses focusing on how CO2 from power plants, industrial sources, or the atmosphere can be leveraged to improve mining practices in order to successfully meet the growing domestic demand, economic feasibility, and environmental sustainability of critical materials (CMs). ARPA-E is predominantly (not exclusively) interested in approaches targeting the recovery of nickel, cobalt, and chromium deposits in mafic or ultramafic rock formations.

This is a request for information only. This notice does not constitute a Funding Opportunity Announcement (FOA). No FOA exists at this time.

Responses to this RFI should be submitted in PDF format to by 5:00 PM Eastern Time on February 18, 2021.
