Plug Power delivers first electrolyzer for 100MW green hydrogen project in Portugal

October 2, 2025 |

In New York, Plug Power announced the delivery of its first 10-megawatt (MW) GenEco electrolyzer array to Galp Portugal’s leading integrated energy company.

The array was delivered to Galp’s Sines Refinery, home of the largest proton exchange membrane (PEM) hydrogen electrolyzer project underway in Europe, Plug said.

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, it added.

This project will produce up to 15,000 tons of renewable hydrogen per year, replacing 20% of the grey hydrogen currently used at the Sines Refinery. This switch will reduce the Refinery’s greenhouse gas emissions by approximately 110,000 tons per year. Plug added.
