Overview

Challenge Overview

The American-Made Geothermal Lithium Extraction Prize seeks to drive forward the development of economic DLE from geothermal brines found at the Salton Sea by partnering novel geothermal and non-geothermal expertise with experienced DLE industry experts to overcome challenges of geothermal lithium extraction by:

  • Developing electrochemical/electrolysis processes for the direct conversion of a lithium-bearing geothermal brine to a lithium hydroxide product without the intermediate creation of lithium carbonate.
  • Developing new absorbents, precipitants, catalysts, or new processing conditions that can efficiently and selectively extract lithium directly from geothermal brines.
  • Advancements that improve the yield and achievable product purity.
  • Advancements that reduce energy and water consumption rates.
  • Advancements that minimize and/or monetize waste products.

Lithium is a major component of high-charge-density batteries for electric vehicles and grid-scale electricity storage. It is expected that global demand for lithium will increase by 500% by 2050 due to widespread adoption of electric vehicles and grid-scale battery storage, making lithium supplies a crucial element in the clean energy supply chain. 

The current U.S. lithium stock is almost entirely imported, with only 1% of U.S. lithium supply being sourced domestically. Furthermore, traditional sources of lithium are environmentally destructive. This combination of rapidly expanding global demand and lack of a safe, domestic supply has created an urgency to develop a safe, domestic, cost-competitive source of lithium to ensure American leadership in the transition to a carbon-free economy and a robust domestic supply chain.

Prize Structure

The Geothermal Lithium Extraction Prize consists of three phases that will fast-track efforts to identify, develop, and test disruptive solutions to improve the profitability of DLE from geothermal brines. Each stage will include a contest period when participants work to rapidly advance their solutions.

Reminder: Join the Geothermal Lithium Extraction Prize Informational Webinar Today!

April 12, 2021, 6 a.m. PDT by NREL Challenge

Join the U.S. Department of Energy Geothermal Technologies Office and the National Renewable Energy Laboratory for an informational webinar on the newly announced American-Made Geothermal Lithium Extraction Prize

The Geothermal Lithium Extraction Prize is designed to find solutions that de-risk and increase market viability for direct lithium extraction (DLE) from geothermal brines. Advancement of DLE technologies allow for improved methods that lower cost, lessen environmental impact and further the mission to turn the threat of climate change into an opportunity to revitalize the U.S. energy and critical materials supply chain. Participants compete in three escalating challenges that fast-track efforts to identify, develop, and test disruptive solutions for an opportunity to win a portion of the $4 million cash prize pool. 

The informational webinar is today (4/12) at 1 p.m. ET. This is your opportunity to ask questions and learn more about how your technical solutions can increase the domestic supply of lithium.
