LibertyStream Infrastructure Partners has announced a major milestone: the commencement of lithium carbonate production from its automated continuous-flow refining unit at field operations in the Permian Basin.
This marks the company’s first-ever field production of lithium carbonate from oilfield brine, showcasing a fully integrated, end-to-end pathway from produced water to saleable lithium at the disposal well site.
By combining the refining unit with LibertyStream’s proprietary direct lithium extraction (DLE) technology on existing oilfield infrastructure, the company has developed a scalable template it plans to replicate across high-volume U.S. basins including the Permian and Bakken.
“Our team at LibertyStream has achieved a rare commercial milestone and we are firmly on the path toward expansion across critical U.S. oilfields in the Permian Basin in Texas and the Bakken in North Dakota,” said Alex Wylie, President & CEO of LibertyStream. “Our automated refining unit in the Permian Basin has now demonstrated that our technology and process—converting oilfield brine into high-purity lithium—has exceeded expectations.”
He emphasized the broader implications: “This breakthrough positions LibertyStream to scale responsibly, supply critical lithium carbonate for domestic industrial customers and defence contractors, and create meaningful shareholder value as we replicate modules and secure long-term commercial contracts.”
Over the past 16 months, LibertyStream’s Texas operations have successfully scaled up through the commissioning of its proprietary Generation 5 DLE unit, capable of processing up to 10,000 barrels of oilfield brine per day into lithium chloride eluate.
Since February 2025, the company has processed more than 350,000 barrels of brine and conducted over 2,500 real-time validation tests, demonstrating the reliability and robustness of its technology.
