Hidrogenii, a joint venture between Plug Power Inc. and Olin Corp., has officially commissioned its 15 metric-ton-per-day hydrogen liquefaction facility in St. Gabriel, Louisiana. The new plant stands among the largest electrolytic hydrogen liquefaction facilities in North America and marks a significant advancement in strengthening the region’s hydrogen infrastructure while supporting the United States’ shift toward low-carbon energy.

The St. Gabriel site is designed to liquefy up to 15 metric tons of hydrogen per day, sourced from hydrogen produced by Olin. The liquefied hydrogen will be transported via trailers to customers across the U.S., primarily supporting Plug’s material handling operations. The facility also contributes to Plug’s innovative spot pricing market for hydrogen distribution. With this addition, Plug's total hydrogen liquefaction capacity now reaches 40 metric tons per day.

“This Louisiana plant is a key milestone in the expansion of our U.S. hydrogen network,” said Andy Marsh, CEO of Plug. “It strengthens our financial outlook by offering a reliable and cost-effective hydrogen source, which reduces our dependence on third-party suppliers.”

Ken Lane, president and CEO of Olin, emphasized the strategic value of the partnership. “This joint venture reflects Olin’s value-first approach. It builds on our leadership positions by pursuing high-value adjacencies and bolt-on opportunities that are consistent with our capital allocation framework,” he said.

Hidrogenii was established in 2022 as a strategic collaboration between Plug and Olin to develop and operate the St. Gabriel facility. The plant features advanced technology to support the production and liquefaction of hydrogen and plays a critical role in Plug’s long-term strategy to develop a robust, national green hydrogen network.

The St. Gabriel facility joins Plug’s other hydrogen production sites, including a 15 TPD plant in Woodbine, Georgia, and a 10 TPD facility in Charleston, Tennessee. Together, these locations are central to Plug’s efforts to provide accessible and sustainable hydrogen solutions across North America.

As demand for clean energy continues to grow, the commissioning of this plant positions Hidrogenii and its partners to play a vital role in meeting the evolving needs of industrial and transportation markets. The facility not only enhances Plug’s supply capabilities but also underscores the importance of public-private partnerships in driving the hydrogen economy forward.

Hidrogenii is a U.S.-based joint venture between Plug Power Inc. and Olin Corp., uniting Plug’s advanced hydrogen technology with Olin’s long-standing industrial expertise. The partnership is dedicated to producing and supplying dependable, domestically sourced hydrogen to meet rising demand across the mobility, power, and industrial sectors. By utilizing existing infrastructure and capitalizing on a strong history of hydrogen innovation, Hidrogenii is playing a key role in establishing the foundation of the American hydrogen economy.
