Hydrogen company Tree Energy Solutions and EWE have signed an MOU to build a 500MW electrolyser in TES’ green energy hub in Wilhelmshaven on Germany’s North Sea coast.
The electrolyser is to be installed in 2028, with operations starting that year. One more unit is planned to reach a total capacity of 1GW.
The hub can accommodate up to 2GW capacity electrolysers with renewable energy sources such as offshore wind in order to generate locally produced green hydrogen.
TES and EWE said in a statement that they will both benefit from “the synergies like the joint connection to the grid or the utilisation of oxygen in other green energy processes”.
The companies said the MOU is in line with Germany’s strategic energy policy to develop clean energy generated by the North Sea and broaden the possible supply for hydrogen.
They added that the signing marks a joint interest in delivering national energy security as Germany continues to diversify its energy supply from renewable energy sources.
“The signing of this MoU is a clear example of the progress underway for Wilhelmshaven to become a major green energy hub for all of Europe, which will not only import green energy but also generate locally produced hydrogen,” said Marco Alvera’, CEO of TES.
“We look forward to our collaboration with EWE in order to harness untapped energy potential and accelerate the transition to deliver affordable energy for all.”
Dr. Urban Keussen, CTO of EWE, said that without hydrogen “there can be no energy transition, no climate neutrality, and no move away from fossil fuels”.
“In order to fill the national hydrogen strategy with life and to advance the topic of hydrogen together, partnerships and suitable location concepts are needed,” Keussen added.
“Wilhelmshaven, as an energy hub, plays a crucial role in this. Together with TES, we want to develop Wilhelmshaven with a focus on green hydrogen and contribute our know-how to the planned partnership.”
