Lilac Solutions, founded in 2016 and based in Oakland, California, specializes in innovative lithium extraction technology designed for the electric vehicle era. The company develops and implements advanced ion exchange (IX) technology that transforms how lithium is obtained from brine resources. This technology addresses the increasing global demand for lithium, essential for electric vehicle batteries and energy storage systems. By offering efficient and environmentally conscious extraction methods, Lilac Solutions contributes significantly to the sustainability of lithium production while supporting the transition to electric mobility.
Battery Technology
Lilac Solutions’ patented ion exchange technology represents a significant advancement in lithium extraction methodology. Their system utilizes specialized ceramic beads engineered for durability and performance, capable of extracting lithium from various brine sources, including salar, geothermal, and oilfield brines. The process achieves high recovery rates even in conditions where lithium concentration is low.
The technology functions through a precise sequence: ion exchange beads are loaded into tanks where brine flows through. These beads selectively absorb lithium from the brine. Once saturated, hydrochloric acid releases the lithium, creating lithium chloride. This intermediate product is then processed into lithium carbonate or lithium hydroxide, materials essential for battery manufacturing.
This method offers substantial advantages over traditional extraction techniques, reducing water consumption by up to 90% and eliminating the need for evaporation ponds. The technology maintains high efficiency while minimizing environmental impact, making it particularly valuable for sustainable lithium production in various geological settings.
Recent Projects
In February 2024, Lilac Solutions secured $145 million in funding to establish a U.S. lithium supply chain. The company also introduced its Gen 4 IX technology in mid-2024, designed to extract lithium from brines with low concentrations and high impurity levels. This advancement opens new possibilities for lithium production across the U.S. and Europe. Additionally, Lilac has initiated projects at Utah’s Great Salt Lake and commissioned a demonstration plant in Jujuy, Argentina, showcasing the versatility of their technology across different geological environments.
Investors
Lilac Solutions has raised $318.46 million through various funding rounds, with notable investors including Mercuria and Lowercarbon Capital, who led the Series C funding round. Other significant investors include Breakthrough Energy Ventures, T. Rowe Price Association, BMW i Ventures, Mitsubishi Corporation, and The Nature Conservancy. The diverse investor base combines expertise from energy, automotive, and environmental sectors, supporting Lilac’s mission to transform lithium extraction practices.
