Hidrogenii, the joint venture between Plug Power Inc. and Olin Corporation, has announced the commissioning of its 15 metric-ton-per-day (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. With this launch, Hidrogenii advances its commitment to building a resilient domestic hydrogen infrastructure—supporting material handling, mobility, and industrial markets across the country.
In a strategic move to scale the U.S. hydrogen economy, Plug Power Inc. and Olin Corporation have announced the commissioning of a new liquid hydrogen plant in St. Gabriel, Louisiana. Operated under their joint venture Hidrogenii, the facility is now producing hydrogen for trailer shipments across the country, serving Plug’s material handling customers and supplying product through Plug’s spot pricing market.
With a design capacity of up to 15 tons per day (TPD), the Louisiana plant marks a significant step forward in Plug’s national hydrogen network. At full operation, the plant brings Plug’s total U.S. liquid hydrogen production to 40 TPD, joining existing facilities in Woodbine, Georgia (15 TPD) and Charleston, Tennessee (10 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,” said Andy Marsh, CEO of Plug Power.
Olin President and CEO Ken Lane emphasized the strategic alignment, stating, “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.”
Formed in 2022, Hidrogenii combines Plug’s leadership in hydrogen technology with Olin’s manufacturing scale and decades of industrial chemical experience. The St. Gabriel facility represents the next step in Plug’s broader goal to create a fully integrated green hydrogen network across the United States, targeting sectors including mobility, power generation, and industrial use.
Plug Power continues to lead the transition to a low-carbon economy with a portfolio that spans hydrogen production, storage, delivery, and fuel cell technology. The company has deployed over 72,000 fuel cell systems and 275 fueling stations worldwide, and it remains the largest user of liquid hydrogen globally. Its efforts are supported by key customers including Walmart, Amazon, and Home Depot.
Olin Corporation, a leader in chemical production and ammunition manufacturing, brings deep operational expertise to the joint venture. Its vertically integrated approach supports the reliable production and delivery of hydrogen alongside a wide range of chemical products.
By building on existing infrastructure and expanding hydrogen availability, the new Louisiana facility strengthens the domestic supply chain while positioning Hidrogenii to meet the growing demand for clean hydrogen in the U.S. economy.
