Uniper’s Green Wilhelmshaven project in Northern Germany gains ground

German energy major Uniper has selected U.S. electrolyzer manufacturer Electric Hydrogen to design a 200 megawatt (MW) electrolyzer plant within its Green Wilhelmshaven project in Northern Germany.

As disclosed, the U.S. company began conducting the preliminary front-end engineering design (pre-FEED) work for the project in October 2024.

The Green Wilhelmshaven consists of two major systems: large-scale electrolysis, which will produce green hydrogen, and an import terminal for ammonia. The large-scale electrolysis will use renewable electricity from wind farms.

According to Uniper, the electrolyzer will be built in Wilhelmshaven on the site of the company’s former coal-fired power plant, while 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.

Both plants will be connected via pipelines to the German hydrogen backbone as well as to underground storage facilities in Northern Germany. With this project, Uniper aims to transform Wilhelmshaven into a central hub for green hydrogen in Germany.

Susanne Thöle, Director of Hydrogen for Uniper, commented: “We aim to drive the efforts to decarbonize German and European industry. Uniper’s hydrogen project is a cornerstone of our plans to shape the energy transition. We’re excited to begin the pre-FEED work on this project with Electric Hydrogen, in whom we have found a partner who understands our goals and supports our vision. We want to be the most trusted partner for policymakers, industry and society on how to make Europe’s energy supply secure, affordable, and steadily greener.”

Raffi Garabedian, CEO of Electric Hydrogen, stated: “Uniper is committed to become a leader in low-carbon energy. We’re excited to help them fulfil this mission by bringing our advanced electrolysis technology and low project cost to Wilhelmshaven as their exclusive electrolysis partner. Electric Hydrogen was founded to make the switch from fossil fuels to zero-carbon green hydrogen an economic inevitability. Green Wilhelmshaven is a monumental step toward that goal.”
