Green Hydrogen for Europe’s Refineries: Plug Power Installs 100 MW of Electrolyzers at Galp’s Sines Refinery

Slingerlands (USA) – Plug Power has completed the installation of PEM GenEco electrolyzers with a total capacity of 100 MW at the Sines refinery operated by the Portuguese energy group Galp. The project ranks among the largest renewable hydrogen initiatives in Europe and marks an important step toward reducing CO₂ emissions in the refining industry.

According to Plug Power, all ten electrolyzer arrays, each with a capacity of ten megawatts, have been delivered to and installed at the refinery site since the project was first announced in October 2025. Commissioning of the systems is expected to begin in the coming months. Once fully operational, the facilities are expected to produce up to 15,000 tonnes of renewable hydrogen per year. This would replace around 20 percent of the refinery’s current use of grey hydrogen. CO₂ emissions are expected to be reduced by approximately 110,000 tonnes per year, based on Scope 1 and 2.

Jose Luis Crespo, President and Chief Revenue Officer of Plug Power, described the project as proof “that large-scale green hydrogen is not just possible – it is already happening.” The Sines refinery, he said, represents a “defining moment for Europe’s energy transition.”

Galp also sees strategic importance in the project. Executive Board member Ronald Doesburg said the initiative brings the company “a decisive step closer to the industrial-scale production of green hydrogen” and is relevant for the development of low-carbon fuels in sectors that cannot be directly electrified.

The project is part of Plug Power’s European growth strategy. The company is planning further large-scale electrolyzer installations in several countries. The technology deployed in Sines is based on a transatlantic supply chain with components sourced from the United States and Europe.

Plug Power shares, which are listed in the renewable energy stock index RENIXX World, gained 3 percent over the past week to reach a price of €2.09 (closing price on 23 January 2026, Stuttgart Stock Exchange). On the current trading day, the stock is slightly lower in morning trading.
