Uniper has selected Electric Hydrogen as its exclusive partner to design a 200 MW electrolyser plant for the large-scale electrolysis within Uniper’s Green Wilhelmshaven project in northern Germany. Electric Hydrogen began conducting the preliminary front-end engineering design (pre-FEED) work for the project in October 2024.
Uniper’s Green Wilhelmshaven project consists of two major systems: large-scale electrolysis, which will produce green hydrogen, and an import terminal for ammonia. The electrolyser will be built in Wilhelmshaven on the site of Uniper’s former coal-fired power plant. The ammonia import terminal is planned to be in the immediate vicinity of the first LNG terminal in the north of Wilhelmshaven, which is operated by a Uniper subsidiary.
Together, the two projects could meet a significant quantity of Germany’s projected demand for green hydrogen. Both plants will be connected via pipelines to the German hydrogen backbone and to underground storage facilities in northern Germany. With the Green Wilhelmshaven projects, Uniper aims to transform Wilhelmshaven into a central hub for green hydrogen in the country. This is also confirmed by the ‘Project of Common Interest’ status granted by the EU to both projects.
The large-scale electrolysis will use renewable electricity from wind farms, creating zero-carbon green hydrogen gas for Uniper’s industrial customers. Green hydrogen plays a critical role in enabling industries like chemicals, steel, marine and air transport to chart a realistic path to carbon neutrality.
The availability of Electric Hydrogen’s advanced proton exchange membrane electrolysis was a big factor in the award decision, along with the company’s offering of a fully integrated plant design to minimise hydrogen production costs. Electric Hydrogen’s 100 MW electrolyser plants will be available for deployment in the European Union in 2026.
“We aim to drive the efforts to decarbonise German and European industry. Uniper’s hydrogen project is a cornerstone of our plans to shape the energy transition,” commented Susanne Thöle, director of Hydrogen for Uniper.
