The goal of this project is to design a pre-treatment process based on the chemical composition of the geothermal fluids at the project site and demonstrate its technical performance on a pilot-scale. The process will remove silica and heavy metals and essentially make the brine ready for subsequent extraction of lithium. The developed process will provide a path to a technically feasible lithium extraction process with favorable commercial scale economics.
Integrating lithium production with geothermal power production operations has the potential to decrease electricity prices from geothermal operations by ~35%.
Expanding geothermal operations and developing lithium production in California could produce over $10 billion of new revenue and create over 3,000 new jobs.
As the state of California continues to progress towards 100% renewable energy, reliability and spinning reserves are going to become increasingly important. Geothermal energy provides valuable inertia and capacity required by grid operators.
