Plug Proves European Hydrogen Supply and Delivery Capabilities; Successfully Completes Deliveries to H2CAST Project, Signs New Contract for Additional 35 Tons
SLINGERLANDS, N.Y., Oct. 21, 2025 (GLOBE NEWSWIRE) -- Plug Power Inc. (NASDAQ:PLUG), a global leader in comprehensive hydrogen solutions for the hydrogen economy, today announced the completion of the first phase of its hydrogen supply delivery of 44.5 metric tons for H2CAST (Hydrogen Cavern Storage Transition), a joint project led by Gasunie and STORAG ETZEL in Germany. Gasunie is an energy-infrastructure company and operator of gas pipelines in the Netherlands and North West Germany and STORAG ETZEL is the largest independent supplier of cavern storage facilities in Germany. The initiative is repurposing two existing salt caverns into underground storage for renewable hydrogen. Such projects are critical to advancing the energy transition, as salt caverns enable seasonal and high-capacity storage. They provide essential services such as grid balancing and flexibility for renewable energy integration, while ensuring a continuous supply of hydrogen to industrial users. This approach contributes to the development of the broader European hydrogen infrastructure.
From April to August, 2025, Plug safely delivered hydrogen to the H2CAST salt cavern, meeting delivery timelines and proving the viability of large-scale hydrogen transport and storage in Germany. Following this successful pilot, Plug was awarded a second delivery mandate for an additional 35 metric tons of hydrogen to the same project H2CAST. Plug will continue to source the hydrogen from Hy2Gen ATLANTIS, the electrolyzer facility in Werlte, Germany, where Plug holds exclusivity on 100% of the green hydrogen produced.
"The success of our recent projects in Germany with H2CAST show that hydrogen works, and that it is scalable for strategic national energy requirements," said Jose Luis Crespo, President and CRO of Plug. "Plug's ability to deliver hydrogen on time, at volume, and with our own transport and delivery equipment for our customers underscores Plug's leadership in Europe's fast-growing hydrogen economy."
Plug's execution in Germany reflects the company's broader corporate objective: building unmatched hydrogen production and fleet capacity across the European Union. With a fleet of 36 Multi Element Gas Containers (MEGCs)—rated at 350/380 bar pressure standards —Plug has established a flexible, scalable delivery capability. Plug continues to expand its hydrogen production capacity in Europe, underscoring the market demand for Plug's vertically-integrated approach to meeting hydrogen customer needs.
The H2CAST project expansion also demonstrates Plug's engineering strength. The company designed a dedicated unloading skid for the facility, developed by its Netherlands-based team, bridging trailer operations directly into the customer's existing infrastructure. This ability to quickly offer tailored solutions not only ensures seamless delivery, but also enables customers to maximize the commercial value of hydrogen.
By delivering green hydrogen production and delivery capacity, Plug is proving that hydrogen is not only viable but ready to play a central role in Europe's energy mix. These milestones in Germany serve as a cornerstone for Plug's expanding European operations—reinforcing it as a global industrial gas company and a leading participant in the hydrogen ecosystem worldwide.
