Gen 5 boosts reactor throughput, increases IX media productivity and durability, enhances eluate quality, and simplifies brine pretreatment. These advancements deliver simpler project flowsheets, driving down capital and operating costs for lithium producers.

Pilot plant using Gen 5 Lilac IX and oilfield brine from wells at Neptune Energy’s site in Steinitz, Saxony-Anhalt, Germany.  Marks Lilac’s first pilot in Europe and first oilfield brine pilot.

Lithium pilot on the Great Salt Lake in Utah, USA, achieved 87% average lithium recovery on 69 mg/​L Li brine and 99.97% overall impurity rejection. Lilac’s non-consumptive and non-contaminating process reinjects lithium-depleted brine back into the lake and does not lower lake water levels. 

Lilac’s Gen 4 demonstration plant in Jujuy, Argentina achieves 91% lithium recovery from a 300 mg/​L salar brine. The plant used an IX vessel that is ~1/3 the size of what will be used at commercial scale.

Lilac begins civil and other works to support its eventual commercial line in Fernley, Nevada.

Lilac announces Gen 4 Lilac IX which delivers advancements in IXM durability, enabling 4,000 cycles even for low-grade brines, 90%+ lithium recoveries for most brines, and capital cost improvements.

Lilac completes pilot in Chile, with 94% lithium recovery on a 2,200 mg/​L brine using Gen 2 Lilac IX.

Lilac closes $145M in Series C financing led by Mercuria, Lowercarbon Capital, and Breakthrough Energy Ventures.

Lilac completes first demonstration-scale pilot in Argentina with Lake Resources, achieving all technical and operational targets, including high lithium recovery and minimal water usage.

Lilac improves IXM cycle life to 3,000 cycles, redesigns lithium extraction module with 100% off-the-shelf equipment.

Lilac closes $150M in Series B financing led by Lowercarbon Capital.

Lilac deploys first field pilot and successfully demonstrates technology under harsh field conditions.

IXM durability improves to 1,000 cycles.

Successfully expands bead manufacturing from lab scale to pilot scale, to produce IXM for field pilots globally.

Lilac raises $20M in Series A funding, led by Breakthrough Energy Ventures.

Lilac demonstrates technology at pilot scale in Oakland, CA.

Lilac demonstrates 300 absorption cycles, an early milestone in improved durability of ceramic ion exchange media (IXM), historically constrained to 10’s of cycles.

Lilac opens lab and develops first generation of the company’s lithium ion exchange technology.

Lilac closes $800,000 seed financing round led by angel investors.

Dave Snydacker founds Lilac Solutions in 2016 and begins developing the company’s patent portfolio. Lilac sets up shop in California’s East Bay.
