Water and resource recovery company Gradiant’s alkaLi division has unveiled plans to design, build, own and operate a lithium production facility in the Marcellus Shale formation in Pennsylvania.
The project is claimed to be the world’s first such lithiThe vertically integrated approach of the Pennsylvania facility aims to secure a stable US lithium supply and circumvent common project delays.
The facility is currently undergoing testing, with impressive results including 97% lithium recovery and 99.5% purity levels for battery-grade lithium carbonate. Full commercial operations are set to commence in early 2026.
Gradiant CEO Anurag Bajpayee said: “We now have a fully operational lithium production asset in the US that proves what EC² can deliver. This isn’t a concept – it is 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 US lithium demand, validates the maturity of alkaLi’s technology and secures a long-term domestic supply.”um production facility to produce lithium from oilfield-produced water.
This facility will implement the company’s proprietary Extract, Concentrate and Convert (EC²) technology to deliver battery-grade lithium carbonate.
The initiative follows the successful launch of alkaLi’s EC² platform last year, which promises at least 95% lithium recovery at customer sites.
The patented EC² process integrates direct lithium extraction (DLE), concentration and conversion into a singular, efficient system.
This method boasts up to 50% lower capital and operational costs, modular designs for swift global implementation, AI-optimised performance and reduced environmental impact, all while offering flexibility in feedwater sources.
