Plug Power Installs 100 MW Electrolyzers at Galp’s Sines Refinery
Event summary
- Plug Power completed installation of 100 MW GenEco electrolyzer units at Galp’s Sines Refinery in January 2026.
- The project, announced in October 2025, involves ten 10MW arrays and is one of Europe’s largest renewable hydrogen initiatives.
- Once operational, the system will produce up to 15,000 tons of renewable hydrogen annually, reducing emissions by 110,000 tons (CO2e).
- Commissioning of the electrolyzer systems is expected to begin in the coming months.
The big picture
This installation marks a significant milestone in Europe’s energy transition, demonstrating the feasibility of large-scale green hydrogen production. The project aligns with broader industrial decarbonization efforts, particularly in hard-to-electrify sectors like refining. Plug Power’s strategic focus on Europe underscores its commitment to supporting regional energy resilience and advancing low-carbon fuel markets.
