Lilac Solutions
Lilac Solutions is an Oakland-based cleantech company commercializing a patented ion-exchange technology that pulls lithium directly out of brine - using ceramic beads instead of evaporation ponds. The process is faster, uses up to 90% less freshwater, and is designed to unlock low-grade brine resources around the world to feed the electric-vehicle battery supply chain.
