Standard Lithium Installs Carbon Capture Pilot Plant, Testing Novel Technology to Limit Emissions and Advance Sustainability

Carbon Capture Pilot Plant has Been Successfully Designed, Constructed, and Installed at the Testing Location in Southern Arkansas, in Collaboration with Investment Partner Aqualung Carbon Capture AS

EL DORADO, Ark., Jan. 31, 2023 (GLOBE NEWSWIRE) -- Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (TSXV: SLI) (NYSE American: SLI) (FRA: S5L), a leading near-commercial lithium company, is pleased to announce that its Carbon Capture Pilot Plant has been successfully installed at the final testing location in southern Arkansas (see news release dated 14^th September 2021). The Carbon Capture Pilot Plant will assess the technical and financial viability of capturing CO₂ directly from natural gas burning flue-gas streams, and will inform how Standard Lithium can use technology to minimize CO₂ emissions at future production facilities.

Dr. Andy Robinson, President and COO of Standard Lithium commented, “Standard Lithium is committed to ushering in a new generation of sustainable mineral extraction by exploring novel, cutting-edge technologies designed to minimize carbon emissions. We look forward to testing this innovative carbon capture technology to better understand how Standard Lithium can engage in the most sustainable production processes, while integrating low-carbon lithium products into North America’s energy transition supply chain.”

This pilot testing supports the Company’s wider Carbon Capture Utilization and Sequestration (“CCUS”) strategy, and will be integrated with ongoing work to understand how captured carbon can be utilized in the Company’s lithium brine processing flowsheet, and potentially in permanent geological sequestration (see news release dated 13^th July 2022). Standard Lithium is one of the owners of this novel carbon capture technology via a $2.5 million equity investment in Aqualung Carbon Capture AS (“Aqualung”) (see news release dated 12^th May 2022).

The Carbon Capture Pilot Plant was designed and constructed in the United Kingdom by Standard Lithium’s partner, Aqualung. Following initial commissioning and testing with a CO₂-rich flue-gas stream, the plant was then shipped to the Gulf Coast and installed at the final testing location, a natural gas processing site in southern Arkansas that is owned and operated by Mission Creek Resources LLC (“Mission Creek”).
