In a significant step toward decarbonizing refining operations, Plug Power has delivered a large-scale electrolyzer system to Portugal’s Sines Refinery. The installation is designed to produce up to 15,000 tons of renewable hydrogen annually, replacing nearly 20% of the site’s current use of gray hydrogen.

The integration of green hydrogen is expected to reduce carbon emissions at the facility by around 110,000 tons per year, covering both Scope 1 and Scope 2 emissions. This initiative forms part of Galp’s broader strategy to transition its refining operations toward low-carbon alternatives while aligning with European Union climate objectives.

Renewable hydrogen is increasingly being viewed as a vital solution for hard-to-abate sectors such as refining, aviation, and heavy transport. By introducing this technology, Sines becomes one of Europe’s leading examples of hydrogen deployment at scale in a refinery setting.

The project also highlights the growing role of partnerships between technology providers like Plug Power and energy companies committed to sustainability. It reinforces how hydrogen can complement traditional refining processes while creating a commercially scalable path to cleaner fuels.
