US-based Century Lithium is reported to have announced, on 22 September 2026, that it is advancing plans for a commercial chlor-alkali plant with a chlorine capacity of 300 short tons per day (st/d). The plant is described as producing chlorine, hydrochloric acid and sodium hydroxide (caustic soda) from sodium chloride, water and electricity. The company reportedly leaves room to expand capacity to 600 st/d depending on regional demand.
The facility is said to be a standalone plant separate from the Angel Island Lithium Project in Esmeralda County, Nevada. The Angel Island feasibility study includes an on-site chlor-alkali plant, but this facility is distinct from it. The company is reported to regard chlor-alkali products as a fundamental component of the critical minerals supply chain.
Candidate sites are in Nevada and Utah, with final selection expected shortly. Site due diligence is underway, and property acquisition, front-end engineering and design (FEED) and permitting are to follow site selection. The technology is described only as proven chlor-alkali technology, and no specific supplier has reportedly been disclosed.
Initial capacity is 300 st/d of chlorine, expandable to 600 st/d depending on demand. Eight non-binding memoranda of understanding (MOUs) with third-party industrial and chemical companies reportedly cover the full initial production. Total project cost has not been disclosed, and no financing has reportedly been secured.
The company is said to be seeking non-dilutive, project-level funding through vendor financing, institutional preferred equity, offtake prepayments and US government critical minerals programs.
First, a standalone chlor-alkali facility aimed at regional supply of chlorine, caustic soda and hydrochloric acid used in mineral processing such as lithium illustrates strengthening links between basic chemical plants and the minerals supply chain. Second, eight non-binding MOUs covering the full initial output indicate the project is at the demand-confirmation stage, so conversion to firm contracts is key to viability. Third, with no site confirmed and no financing secured, the project remains at an early stage. Fourth, long-lead electrical equipment is recognized as a schedule constraint, making procurement planning a variable for project management.
First, the final site selection between Nevada and Utah. Second, whether a FEED contractor is selected and a technology supplier disclosed. Third, whether the offtake MOUs convert into binding contracts. Fourth, whether the project-level financing structure and total cost are disclosed.
