  • Funding Amount: $10.9 Million
  • FOA Number: DE-FOA-0002823


On July 24, the U.S. Department of Energy (DOE) announced $10.9 million for 10 projects across nine states that will advance innovative technologies to extract and convert battery-grade lithium from geothermal brine sources in the United States. This work will increase America’s access to cost-effective, domestic sources of this critical material needed for batteries for stationary storage and electric vehicles to meet the Biden–Harris Administration’s goals of 50% electric vehicle adoption by 2030 and a net-zero emissions economy by 2050.

These projects are being managed in collaboration by EERE’s AMMTO and GTO. The projects add to a portfolio of recent investments such as AMMTO’s Critical Materials Institute — an Energy Innovation Hub led by Ames National Laboratory and GTO’s Geothermal Lithium Extraction Prize.

These projects will also further develop a DOE-led innovation ecosystem around lithium production as project participants will be invited to participate in the Lithium RD&D Virtual Center. The Center coordinates investment activity across industry, government, and academia.

Topic Areas

The 10 projects were selected from two topic areas:

  1. Field Validation of Lithium Hydroxide Production from Geothermal Brines: Pilot or demonstration projects to validate cost-effective, innovative lithium extraction and lithium hydroxide conversion technologies.
  2. Applied Research & Development for Direct Lithium Extraction from Geothermal Brines: Research and development projects to advance emerging direct lithium extraction (DLE) process technologies to increase efficiency, reduce waste generation, and/or reduce cost of DLE.

Selected Projects

Award and cost share amounts are subject to change, pending negotiations.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it!! So, we've decided to completely nix paywalls here at CleanTechnica. But...
