This site is the world’s first to Extract, Concentrate, and Convert (EC²) lithium in a fully integrated, end-to-end process from oilfield produced water.
[On June 27, Marcellus Drilling News reported Rain City Resources and Avonlea Lithium Corporation announced the successful completion of a pilot test of the proprietary ACCELi technology using lithium-rich wastewater sourced from fracking in the Marcellus Shale, Pennsylvania. The wastewater was processed at the Kendra II Plant based in Springville, Susquehanna County. Read more here.]
This announcement builds on last year’s launch of alkaLi’s EC² platform, which guarantees a minimum 95% lithium recovery at customer sites—empowering producers to deliver battery-grade lithium carbonate faster, cheaper, and more sustainably.
Gradiant’s alkaLi owns and operates the Pennsylvania facility—including equipment, land, water and mineral rights, and permits.
This vertically integrated model secures long-term U.S. lithium supply while avoiding the permitting and ownership delays that often stall critical mineral projects.
Marcellus Drilling News identified this site as the C2G Energy Solutions LLC wastewater treatment facility near Montrose, Susquehanna County.
Currently in testing, the system has already proven key benchmarks: 97% lithium recovery from produced water and 99.5% purity for battery-grade lithium carbonate. Full commercial operations are on track for early 2026.
alkaLi has signed a multi-year offtake agreement to supply up to 5,000 metric tonnes annually of battery-grade lithium carbonate to a U.S. lithium-ion battery manufacturer for electric vehicles (EVs) and energy storage systems (ESS).
The deal affirms strong market demand and the commercial readiness of alkaLi’s solution.
“We now have a fully operational lithium production asset in the U.S. that proves what EC² can deliver,” said Anurag Bajpayee, CEO of Gradiant. “This isn’t a concept—it’s a live facility demonstrating that clean, domestic lithium production is both viable and scalable. Our goal isn’t to compete with customers, but to empower them—and the broader industry—to meet surging demand for battery-grade lithium and accelerate the clean energy transition. This strategic investment in the Marcellus Shale, which could supply 50% of U.S. lithium demand, validates the maturity of alkaLi’s technology and secures a long-term domestic supply.”
