According to the announcement, privately-held Lilac is part of a growing number of technology developers seeking to extract lithium from saltwater brines faster, cheaper, and with less water than evaporation ponds, which have long been the industry standard.
BMW, which already buys lithium from China’s Ganfeng Lithium Co and other traditional lithium producers, said it sees Lilac’s technology as a way to boost global production of the white metal as demand grows from the EV market.
“This holds the promise of becoming a new extraction technology that allows access to more green lithium,” Kasper Sage of BMW I Ventures, BMW’s venture capital fund said.
The global automaker is also participating in Lilac’s Series B funding round alongside SK Materials Co, Sumitomo Corp investment arm Presidio Ventures, and others.
BMW declined to discuss its investment amount, though the total from all investors announced on Wednesday was less than $20 million, according to regulatory filings.
Meanwhile, Lilac plans to use the funds to construct a US manufacturing facility for ion exchange beads, which are core to its extraction process. The company last month agreed to use its technology to develop a lithium project in Argentina with Lake Resources NL.
“Lilac has focused on proving our technology is reliable and scalable. And that’s been resonating with members of the supply chain,” Dave Snydacker, Lilac’s chief executive said.
