American-Made Challenges

Geothermal Lithium Extraction Prize

The American-Made 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.

The Geothermal Lithium Extraction Prize

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. Traditional sources of lithium are environmentally destructive and cost-prohibitive due to the complexity of the extraction process. The combination of rapidly expanding global demand and lack of a secure domestic supply has created an urgency to develop a safe, domestic, and cost-competitive source of lithium. Advancements in domestic geothermal lithium extraction will also help ensure American leadership in the transition to a carbon-free economy and clean energy job creation throughout 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.
