Princeton Critical Minerals (PCM) has raised $16 million to expand sales and commercial deployments of its brine-based lithium production platform in the U.S. and South America. The company's technology improves efficiency and scalability of lithium production from brine sources, addressing increasing demand for critical minerals used in energy storage, electrification, and AI infrastructure. PCM's systems aim to increase throughput while reducing energy use, chemical consumption, and operational complexity in lithium production. The company has successfully deployed its technology in Chile and is preparing for commercial deployments in the U.S. to meet the growing global demand for lithium. PCM is field-testing new technologies in Chile to enhance evaporation and optimize processes using AI, in order to increase lithium production efficiency and meet growing demand. The company plans to scale manufacturing, expand commercial deployments, and build U.S.-based production capabilities with new funding. PCM aims to support the global critical mineral supply chains for energy storage, electrification, and digital systems. The successful deployment of Lilypad has led to plans for additional pilot projects in Chile, with growing demand from major lithium producers.
