The St. Gabriel facility is designed to liquefy hydrogen produced by Olin for distribution via trailers across the U.S. It serves Plug Power’s material handling customers and operates under the company’s innovative spot pricing model. With a maximum capacity of 15 TPD, the plant boosts Plug Power’s total hydrogen production capacity to 40 TPD. Earlier in 2025, Plug Power secured a $1.7-billion loan guarantee from the U.S. Department of Energy to further its hydrogen production initiatives. The company also revealed plans to establish production facilities in India.
“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 Plug CEO Andy Marsh.
Ken Lane, president and CEO of Olin, stated: “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 was created by Plug Power and Olin to construct and manage the St. Gabriel plant. The facility complements Plug Power’s existing hydrogen production sites in Woodbine, Georgia (15 TPD), and Charleston, Tennessee (10 TPD), contributing to the company’s strategy to develop a national green hydrogen network.
Headquartered in Latham, New York, Plug Power specializes in electrolyzers, liquid hydrogen, fuel cell systems, storage tanks, and fueling infrastructure. Its solutions support industries such as material handling, industrial applications, and energy production, promoting energy independence and decarbonization globally. The company has deployed over 72,000 fuel cell systems and 275 fueling stations, making it the largest consumer of liquid hydrogen. Olin Corp., based in Clayton, Missouri, is a global leader in manufacturing and distributing chemical products, with a focus on integrated operations.
The commissioning of the St. Gabriel plant underscores the commitment of both companies to advancing clean energy infrastructure and supporting the growing demand for sustainable hydrogen solutions across the United States.
