Uniper (Düsseldorf, Germany; uniper.energy) has selected Electric Hydrogen (Natick, Mass.; www.eh2.com) as its exclusive partner to design a 200 Megawatt (MW) electrolyzer 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 electrolyzer will be built in Wilhelmshaven on the site of Uniper’s former coal-fired power plant. The ammonia import terminal is planned 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 Germany. This is also confirmed by the “Project of Common Interest” (PCI) status granted 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.
