LibertyStream Automates Gen 6 Direct Lithium Extraction System
The system operates at 5,000 barrels per day with cycle times reduced to roughly 20 minutes from about 60 minutes under the Gen 5 configuration.
LibertyStream Infrastructure Partners has commissioned a fully automated version of its Gen 6 direct lithium extraction system, supporting lithium carbonate production at its first deployment site as the company works toward commercial-scale output for EV battery supply chains.
What Happened
The automated Gen 6 system operates at LibertyStream's Freedom Launchpad facility—a platform designed for operator training and customer samples—on a processing basis of 5,000 barrels per day. The configuration runs on programmable logic controls with real-time monitoring of temperature, pressure, flow rates, pH, and conductivity. It builds on 21 months of Gen 6 field operations, more than 400,000 barrels of processed brine, and over 2,500 operating tests. Cycle time has been cut to roughly 20 minutes, compared with about 60 minutes under the earlier Gen 5 setup. The system uses sorbents or membranes rather than evaporation ponds, enabling extraction from low-concentration, high-volume water streams.
Why It Matters
Direct lithium extraction feeds the front end of the EV battery supply chain by producing lithium carbonate—one of two chemicals that feed Li-ion cell manufacturing alongside lithium hydroxide. Faster cycle times mean each extraction module can run more batches per day, improving throughput without expanding physical footprint. The automation also captures process data as LibertyStream advances customer sample evaluations and works toward qualifying its product for commercial use. With electric vehicle adoption continuing to grow, domestic lithium supply chains remain a focus area for manufacturers seeking to reduce reliance on imported materials.
The Bottom Line
LibertyStream is targeting commissioning of its first commercial-scale plant—Freedom 1—by the end of December 2026, with equipment deliveries expected in late Q3 and early Q4 2026. The Stage 1 facility is designed to produce 1,000 tonnes per annum of lithium carbonate under an agreement with Select Water Solutions. The company has already produced and delivered product for customer evaluation and announced a long-term offtake milestone of 600 tonnes per year starting in 2027.
