The installation marks the delivery and on-site placement of all ten GenEco™ electrolyzer arrays at the Sines Refinery, following the project’s initial announcement in October 2025. The first 10 MW module was delivered at that time, with the remaining units subsequently shipped and installed to reach the full 100 MW capacity.
Commissioning of the electrolyzer systems is expected to begin in the coming months. Once operational, the installation is projected to produce up to 15,000 tons of renewable hydrogen per year. According to the companies, this output is expected to replace around 20% of the refinery’s existing gray hydrogen consumption and reduce greenhouse gas emissions by approximately 110,000 tons annually on a Scope 1 and 2 CO₂e basis.
“This installation demonstrates that large-scale green hydrogen is not just possible, it’s happening today and Plug is instrumental in this effort,” said Jose Luis Crespo, President and Chief Revenue Officer of Plug. “The completion of the Sines Refinery project is a defining moment for Europe’s energy transition and a model for the decarbonization of hard-to-electrify industrial sectors.”
Benjamin Haycraft, Chief Strategy Officer at Plug, said that Europe remains a key strategic market for the company and highlighted continued regional investment to support large-scale decarbonization and energy resilience.
“With this pioneering project, Galp is closer to producing green hydrogen at an industrial scale, a historic moment for European refining,” said Ronald Doesburg, Executive Board Member responsible for industrial activities at Galp. He added that the project supports the development of low-carbon fuels for activities that cannot be electrified.
