Dept. of Energy - NOI Lithium Extraction & Conversion from Geothermal Brines

Opportunity Title:

NOI Lithium Extraction & Conversion from Geothermal Brines

Opportunity Number:



The Office of Energy Efficiency and Renewable Energy (EERE) intends to issue, on behalf of the Advanced Manufacturing Office and Geothermal Technologies Office, a joint Funding Opportunity Announcement (FOA) entitled “Lithium Extraction & Conversion from Geothermal Brines”.

Through this FOA, EERE seeks to address gaps in domestic supply chains for lithium batteries for electric vehicles and stationary storage. The U.S. currently has limited production of lithium from domestic sources and also lacks domestic capabilities to refine materials needed to support component manufacturing – including lithium hydroxide needed for lithium battery cathode production. Geothermal brines have proven to be a sustainable resource of critical materials including lithium. Direct lithium extraction from geothermal brines represents an opportunity to produce lithium hydroxide from domestic sources in a safe and environmentally friendly way.

The goals of this FOA are to:

• Enable environmentally and socially responsible domestic manufacturing of battery-grade (i.e., high purity) lithium hydroxide from geothermal brines;

• Diversify the domestic supply of lithium hydroxide;

• Validate and demonstrate domestic pilot plants and related technologies to support the transition to U.S. manufacturing; and

• Mature nascent technologies, processes, and methods to improve treatment of direct lithium extraction influent and effluent streams.
