Hidrogenii, an Olin and Plug Joint Venture, Commissions 15 Ton Per Day Hydrogen Liquefaction Plant in Louisiana

• Hydrogen Capture Enhances Sustainability and Profitability of Olin's St. Gabriel Facility
• Plug US Hydrogen Capacity now at 40 metric-ton-per-day (TPD)

CLAYTON, Mo., April 17, 2025 /PRNewswire/ -- Olin Corporation (NYSE: OLN) announced today that Hidrogenii, the joint venture between Olin and Plug Power Inc. (NASDAQ: PLUG), commissioned its 15 TPD hydrogen liquefaction plant in St. Gabriel, Louisiana. Among the largest electrolytic hydrogen liquefaction facilities in North America, the site marks a major milestone in strengthening the regional hydrogen supply chain and accelerating the U.S. transition to low-carbon energy.

The newly commissioned facility will liquify hydrogen produced by Olin for trailer shipments across the U.S., serving Plug's material handling customers and utilizing Plug's novel spot pricing market. The plant is designed to liquefy up to 15 TPD of hydrogen at maximum capacity, increasing Plug's total production capacity to 40 TPD.

"This Louisiana plant, a milestone in expanding our U.S. hydrogen network, bolsters our financial position by leveraging a dependable, cost-effective hydrogen source, reducing our reliance on third-party suppliers," noted Plug CEO Andy Marsh.

Ken Lane, President and CEO of Olin, added, "This joint venture is consistent with Olin's value-first approach to build on our existing leading positions through high-value adjacencies or bolt-ons that align with our capital allocation framework."

Established in 2022, Hidrogenii was formed by Olin and Plug to build and operate this state-of-the-art liquid hydrogen facility in St. Gabriel, Louisiana. The plant plays a key role in Plug's broader strategy to scale a national green hydrogen network, joining existing Plug production sites in Woodbine, Georgia (15 TPD), and Charleston, Tennessee (10 TPD).
