This announcement describes an exploratory research thrust entitled Critical Mineral Extraction from Macroalgal Biomass. The purpose of this announcement is to (1) solicit Full Applications for the evaluation of the feasibility of extracting critical minerals from macroalgae cultivated in the U.S. Exclusive Economic Zone, (2) encourage partnerships between seaweed farmers and scientists, marine microbiologists, geologists, critical mineral experts, and the mining community, and (3) provide a timetable for the submission of Full Applications.

ARPA-E is interested in receiving full applications investigating the feasibility of extracting critical minerals, specifically Rare Earth Elements (REEs) critical for the production of electric motors and generators, and high-value Platinum Group Metals (PGMs), from macroalgae cultivated and/or harvested within the U.S. Exclusive Economic Zone (EEZ).
