ANDRITZ opens electrolyser gigafactory in Germany

At the site, key components for green hydrogen production have already been produced since March 2025, including electrolyser cell stacks and phase separators which are then subjected to a pressure test and quality control. Depending on customer demand, the output can be flexibly scaled up.

The new gigafactory is located on a site with a long-standing history of industrial manufacturing, where ANDRITZ Schuler has been producing presses for many years. Around 350 people are working in Erfurt, almost 100 will be employed in the electrolyser gigafactory in the future. This existing infrastructure provides a solid foundation for the efficient production and transport of electrolysers.

“With this gigafactory, we not only support our customers in mastering the green transition, but also get closer to our goal of being a leading provider of economically viable solutions here,” said ANDRITZ CEO Dr. Joachim Schönbeck. “At our site in Erfurt, we benefit from the existing infrastructure and look back on over 125 years of expertise in heavy machinery construction. This gives us the best conditions to produce electrolysers on a large scale.”

Strategically located in the heart of Europe, Erfurt offers direct access to major transportation networks. Its proximity to central roadways enables safe and timely delivery to project sites across the continent, ensuring that customers benefit not only from high-quality technology but also from logistical efficiency.

The electrolysers are based on the latest technology from ANDRITZ’s partner HydrogenPro. The first electrolysers produced at the facility are destined for Salzgitter AG’s 100 MW hydrogen plant for low-CO₂ steel production. All green hydrogen products made in Erfurt are CE-certified and meet European safety and performance standards.

Gerd Baresch, Chief Technology Officer of Salzgitter Flachstahl GmbH, commented: “ANDRITZ is an important partner for us on our way to low-CO₂ steel production. For the decarbonisation of our processes and products, we have defined a clear mission for us with the motto ‘partnering for transformation’, to take responsibility for society and future generations together with partners. The 100 MW electrolysis plant that we are now building together with ANDRITZ will enable us to produce hydrogen independently and will therefore contribute to the production of sustainable products at the Salzgitter site in the future.”
