Plug Power, a global leader in comprehensive hydrogen solutions for the hydrogen economy, today 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.

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.

This project, Plug’s largest worldwide, will produce up to 15,000 tons of renewable hydrogen per year, replacing 20 percent 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 (Scope 1 and 2, CO2e).
