Electric Hydrogen Designs Electrolyzer Plant for Green Wilhelmshaven Project

Electric Hydrogen obtained an exclusive contract to design Uniper’s 200-MW electrolyzer plant, enabling large-scale electrolysis for the Green Wilhelmshaven project in Northern Germany. Uniper’s project features large-scale electrolysis to produce green hydrogen and an ammonia import terminal. Electric Hydrogen will build the electrolyzer at Uniper’s former coal-fired power plant, while the ammonia import terminal is planned for construction near the first LNG terminal in north Wilhelmshaven. In October 2024, the company began the pre-FEED work for the project.

“Uniper is committed to becoming a leader in low-carbon energy,” said Raffi Garabedian, CEO of Electric Hydrogen. “We’re excited to help them fulfill 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 step toward that goal.”

Project Impact

Both project plants will be connected to the German hydrogen backbone and underground storage facilities via pipelines, satisfying a large portion of Germany’s expected demand for green hydrogen. The Green Wilhelmshaven projects achieved “Project of Common Interest” status and Uniper aims to convert Wilhelmshaven into the country’s central green hydrogen hub.

“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,” said Susanne Thöle, Director of Hydrogen for Uniper. “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.”

Electric Hydrogen’s Tech

The electrolysis will use renewable electricity from wind farms to generate zero-carbon green hydrogen gas for Uniper’s industrial customers. Electric Hydrogen’s technology was chosen due to proton exchange membrane electrolysis and a fully integrated plant design to minimize hydrogen production costs. The company’s 100-MW electrolyzer plants are available for deployment in the European Union in 2026.
