Paris, France-based Air Liquide invested $150 million to expand Radnor, PA-based Airgas production capacity and pipeline infrastructure in Tennessee, as part of a long-term agreement with LG Chem.

The partnership will involve supplying oxygen to LG Chem’s upcoming cathode active material plant.

Airgas, a subsidiary of Air Liquide, is a distributor of gases, as well as industrial and welding supplies. The company said the investment was “triggered by LG Chem’s new need for oxygen.” Additionally, Airgas is investing in a second ASU, liquefier, storage and pipeline at its Clarksville, TN production facility.

“Airgas is energized by this planned expansion in a key market and collaboration with LG Chem to support expansion of the battery ecosystem in the U.S.,” Airgas CEO and Air Liquide Executive Committee member Marcelo Fioranelli said in an Oct. 15 news release.

The Airgas facility, established in 2013, is set to expand and begin operations in 2027 as part of the investment. The company said the expansion will boost production of oxygen, nitrogen and argon to better serve industrial, healthcare, pharmaceutical, food production, water treatment and other customers across Kentucky and Tennessee.

Airgas is expected to increase its workforce in Clarksville, with hiring anticipated to begin in 2026.

The company is No. 4 on MDM’s Top Distributor’s List for Industrial Supplies and No. 4 on MDM’s unranked Gases & Welding Supplies List.
