Plug Power has successfully delivered the first 10-megawatt (MW) GenEco electrolyzer to Galp's Sines Refinery in Portugal, marking a significant step in the development of a 100MW green hydrogen project.

The module is the first of 10 similar arrays with Hydrogen Processing Units (HPUs) to be delivered on site by early 2026 to deploy a total electrolyzer capacity of 100MW upon completion, in the first half of next year.

The project aims to produce up to 15,000 tons of renewable hydrogen annually, replacing 20% of the refinery's current grey hydrogen use and substantially reducing its greenhouse gas emissions. This switch will reduce the Refinery’s greenhouse gas emissions by approximately 110,000 tons per year (Scope 1 and 2, CO2e).

“Plug is building the next generation of industrial energy solutions, and our collaboration with Galp shows that large-scale hydrogen is ready today,” said Andy Marsh, CEO, Plug. “This system will be a model for what’s possible across Europe’s refining sector and the broader energy industry.”

“Half of all grey hydrogen demand sits today in refineries and chemical plants,” said Ronald Doesburg, Galp’s EVP in charge of the Industrial business unit. “With our first 100 MW, we will have started the decarbonisation of our Sines refinery. It’s a decisive first step for Galp, but also for the industry,” he added.

Galp decided in September of 2023 to build a 100MW green hydrogen electrolysis unit and an HVO/SAF unit in its refinery, in a combined €650 million investment. Construction work started weeks after the final investment decision and is moving swiftly according to plan, one of the very few such projects happening on the ground.

Plug’s GenEco electrolyzer array is supported by a global supply chain and integrates components manufactured across several continents, including the U.S. and Europe. This approach combines regional manufacturing expertise with high-volume scalability to meet surging demand for clean hydrogen produced by PEM technology.
