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.
