Plug Power Inc. (NASDAQ: PLUG) has completed the on-site installation of a 100-megawatt fleet of its GenEco™ proton exchange membrane (PEM) electrolyzers at Galp’s Sines Refinery in Portugal, reaching a major construction milestone for one of Europe’s most significant renewable hydrogen initiatives.
The final installation marks the completion of all ten 10-MW GenEco electrolyzer arrays at the refinery. The project moved rapidly from its initial announcement in October 2025—when the first module was delivered—to full mechanical installation of the entire 100 MW system.
Commissioning of the electrolyzers is scheduled to begin in the coming months. Once in operation, the plant is expected to produce up to 15,000 tonnes of renewable hydrogen annually. This output will replace around 20 percent of the refinery’s existing grey hydrogen consumption and is projected to cut greenhouse gas emissions by approximately 110,000 tonnes per year across Scope 1 and Scope 2 emissions.
“This achievement shows that industrial-scale green hydrogen is no longer a future concept—it is being deployed today,” said José Luis Crespo, President and Chief Revenue Officer of Plug Power. “Completing the installation at Sines is a pivotal moment for Europe’s energy transition and sets a clear example of how hydrogen can decarbonize heavy industry.”
Plug Power emphasized that Europe remains central to its long-term growth strategy. Benjamin Haycraft, Plug’s Chief Strategy Officer, noted that the Sines milestone reflects the company’s ability to deliver complex hydrogen infrastructure at scale. “This project demonstrates our capability to turn strategy into reality—supporting Europe’s decarbonization goals while reinforcing long-term energy resilience,” he said.
For Galp, the project represents a turning point in refinery decarbonization. “This is a historic step toward producing green hydrogen at industrial scale,” said Ronald Doesburg, Executive Board Member responsible for Galp’s industrial activities. “It lays the foundation for a new generation of low-carbon fuels and enables emissions reductions in processes that cannot be electrified.”
The GenEco electrolyzer systems installed at Sines draw on Plug’s global supply chain, with components manufactured across both the United States and Europe. This approach combines regional manufacturing expertise with scalable PEM technology, reinforcing Plug’s position as a leading provider of modular, high-performance hydrogen systems for industrial applications.
The Sines Refinery installation is part of Plug Power’s broader European expansion, which includes multi-gigawatt electrolyzer projects in Spain, the United Kingdom and other key markets. Supported by a global opportunity pipeline valued at approximately $2 billion, Plug continues to deepen its role in enabling large-scale hydrogen adoption across refining, manufacturing and energy-intensive industries.
