Plug Power Inc. Marks Major Milestone with 100 MW GenEco Electrolyzer Installation at Galp’s Sines Refinery

The installation of the 100 MW of electrolyzers represents a significant milestone in what is considered one of Europe’s largest renewable hydrogen initiatives. Following the initial announcement of the project in October 2025, the deployment of ten arrays, each comprising 10 MW, has now reached completion on-site at the refinery.

The commissioning of these electrolyzer systems is set to commence in the upcoming months. Once operational, the facility is expected to produce up to 15,000 tons of renewable hydrogen annually. This production will replace approximately 20% of the refinery's reliance on grey hydrogen and aims to reduce greenhouse gas emissions by an estimated 110,000 tons per year (Scope 1 and 2, CO2e).

Jose Luis Crespo, President and Chief Revenue Officer of Plug, emphasized the significance of the installation, stating, “This installation demonstrates that large-scale green hydrogen is not just possible, it’s happening today and Plug is instrumental in this effort.” He highlighted the project as a defining moment for Europe’s energy transition and a model for decarbonizing industrial sectors that are challenging to electrify.

Benjamin Haycraft, Chief Strategy Officer at Plug, underscored the importance of the European market for the company. “Projects like Sines underscore why Europe remains one of Plug’s most important strategic markets,” he stated. The successful completion of this project is indicative of Plug’s commitment to investing in large-scale decarbonization efforts across the region, facilitating advancements in energy transition and enhancing long-term energy resilience.

Ronald Doesburg, Executive Board Member responsible for Galp’s industrial activities, remarked on the historic nature of the project, stating, “With this pioneering project, Galp is closer to producing green hydrogen at an industrial scale.” He noted that the initiative represents a critical step toward developing a new generation of low-carbon fuels essential for decarbonizing non-electrifiable activities.

Plug Power’s GenEco electrolyzers benefit from a robust global supply chain, incorporating components manufactured across the U.S. and Europe. This integration of regional expertise with scalable PEM technology further solidifies Plug Power’s leadership in delivering modular, high-performance hydrogen systems at an industrial scale.

The Sines project is a key component of Plug’s broader strategic expansion in Europe, which includes plans for multi-gigawatt electrolyzer deployments across Spain, the U.K., and other regions. With a $2 billion global opportunity funnel, Plug continues to pioneer hydrogen solutions that enable partners to decarbonize operations while remaining competitive as low-carbon fuels gain traction in the market.

Plug Power is committed to building the global hydrogen economy through a fully integrated ecosystem encompassing production, storage, delivery, and power generation. As a first mover in the hydrogen industry, Plug provides electrolyzers, liquid hydrogen, fuel cell systems, storage tanks, and fueling infrastructure to a diverse range of sectors, including material handling, industrial applications, and energy production.

With a presence across five continents and a portfolio that includes over 72,000 fuel cell systems and 275 fueling stations, Plug Power is recognized as the largest user of liquid hydrogen globally. The company is rapidly expanding its generation network to ensure a reliable, domestically produced hydrogen supply, with operational plants in Georgia, Tennessee, and Louisiana capable of producing 40 tons of hydrogen per day.

In summary, Plug Power's successful installation of the GenEco electrolyzers at Galp's Sines Refinery not only marks a significant achievement for the company but also serves as a beacon of progress in the transition to renewable energy sources in Europe and beyond.
