Plug Power Selected to Supply a 275 MW Geneco Electrolyzer System for Hy2gen’s Courant Decarbonized Ammonium Nitrate Project in Baie-Comeau, Québec, Canada

Large-scale project award reinforces company’s role as a trusted partner for global industrial decarbonization

Plug Power Inc. (NASDAQ: PLUG), a global leader in comprehensive hydrogen solutions, today announced it has been awarded the Front-End Engineering Design (FEED) contract to supply a 275 MW GenEco PEM electrolyzer system for Hy2gen Canada Inc.’s “Courant” project. The system represents one of the largest electrolyzer project awards to Plug to date, underscoring the company’s leadership in delivering superior hydrogen technology on a global scale.

Hy2gen is developing the Courant project as one of North America’s largest decarbonized ammonium nitrate facilities, supporting the mining industry's goals in Québec, Central and Eastern Canada, and beyond. Plug’s scope includes advanced engineering and system design activities to support electrolyzer integration, plant configuration, and performance optimization. Plug’s PEM electrolyzer technology is well-suited for applications requiring reliability, high efficiency, and operational flexibility.

The large-scale hydrogen plant will support Hy2gen’s production of low-carbon ammonia, using electricity delivered via the Hydro-Québec grid, and that ammonia will then be further processed into renewable ammonium nitrate for the mining industry's explosives needs.

Located in Baie-Comeau, Québec, the facility leverages Canada’s abundant low-carbon hydroelectric resources, established industrial and distribution infrastructure, and deep-water port access.

“Being selected as the electrolyzer supplier for Hy2gen’s Courant project underscores Plug’s ability to support large-scale hydrogen and hydrogen-derived products,” said Jose Luis Crespo, President and Chief Executive Officer of Plug. “This project reflects growing demand for proven electrolyzer technology and experienced partners capable of supporting complex, high-capacity developments required for industrial decarbonization. In choosing Plug, Hy2gen has also recognized our unique ability to serve projects of this large magnitude thanks to Plug’s state-of-the-art gigafactory.”

"This collaboration combines Hy2gen’s project development expertise with Plug’s electrolyzer technology to enable a green chemical project producing low-carbon ammonium nitrate for Canada’s mining industry,” said Cyril Dufau-Sansot, CEO of Hy2gen. “By supporting this strategic sector, we are accelerating practical, large-scale decarbonization.”

The Courant project builds on Plug’s established relationship with Hy2gen, following previous collaborations on renewable hydrogen projects in Europe and ongoing hydrogen supply arrangements. Together, the companies continue to advance large-scale hydrogen projects across multiple geographies, reinforcing Plug’s position as a trusted technology and supply partner for leading global hydrogen developers.
