Plug Power Delivers First Electrolyzer for Galp's 100MW Sines Refinery Project—A Pivotal Move in European Hydrogen Expansion
First 10MW Module Sets the Stage for 100MW Green Hydrogen at Sines
Plug Power (NASDAQ: PLUG) has reached a critical milestone, delivering its first 10-megawatt (MW) GenEco™ electrolyzer array to Galp’s Sines Refinery in Portugal. This shipment is the initial step in deploying 10 total arrays, forming a 100MW installation—one of only a few hydrogen projects in Europe operating at such a scale. The refinery, run by Portugal’s leading integrated energy firm Galp, aims to complete the rollout by early 2026.
Key Numbers: Emissions Reductions and Green Hydrogen Production
When fully operational, the Sines project is expected to produce up to 15,000 tons of renewable hydrogen each year, replacing about 20% of the refinery’s current use of grey hydrogen. This transition is projected to reduce the Sines Refinery’s carbon footprint by approximately 110,000 tons of CO2 equivalent annually. It’s a foundational step in decarbonizing both the refinery and hard-to-electrify industries in the region.
| Project Aspect | Value |
|---|---|
| First Module Delivered | 10 MW |
| Total Capacity Planned | 100 MW |
| Hydrogen Output (annual) | 15,000 tons |
| Grey Hydrogen Replaced | 20% |
| CO2 Emissions Cut (annual) | 110,000 tons |
| Planned Completion | Early 2026 |
Galp’s Decisive Investment in Decarbonization
The Sines green hydrogen initiative is part of a broader EUR 650 million investment by Galp, combining the 100MW electrolyzer and an HVO/SAF (Hydrotreated Vegetable Oil/Sustainable Aviation Fuel) unit. Galp began construction soon after its final investment decision in 2023, placing this project among a small handful actively advancing at the ground level in Europe. According to Galp’s industrial leadership, this is not just a first step for the company—it sets a precedent for refineries and chemical plants across the continent, where nearly half of all grey hydrogen demand exists.
Plug Power's Global Hydrogen Ambitions Backed by Strong Demand
This Sines delivery is Plug’s largest global project to date, leveraging an international supply chain to deliver PEM (proton exchange membrane) hydrogen technology. With electrolyzer programs across five continents and a $2 billion global opportunity pipeline, Plug continues to scale rapidly. In Q2 alone, more than 230MW of GenEco electrolyzer programs contributed $45 million in revenue across regions like Europe, Australia, and North America. Multiple multi-gigawatt projects are on track for final investment decisions in 2026, underlining Plug’s leading role in the sector.
Market and Industry Impact: European Hydrogen Steps Forward
The collaboration between Plug Power and Galp underscores hydrogen’s move from promise to practical deployment, supporting both climate goals and industry competitiveness. With this initial module installed, investors and industry watchers can expect more tangible progress on decarbonization from Europe’s major refiners. As the hydrogen economy gains traction, these large-scale deployments set benchmarks others are likely to follow.
What’s Next for Plug and the Sector?
Plug Power’s early lead and partnerships—serving customers like Walmart, Amazon, BMW, and BP—position it well to ride the wave of clean energy transition. As this project moves toward completion, further developments at Sines and similar refineries across Europe may serve as litmus tests for hydrogen’s true market potential and its ability to replace conventional fuels at scale.
Takeaway: The delivery of Plug Power’s first electrolyzer to the Sines Refinery is more than just an operational milestone—it’s a meaningful signal for green hydrogen adoption and European decarbonization ambitions. Investors and stakeholders will want to monitor how quickly these large-scale transitions can become industry norms as hydrogen demand grows.
