Hamburg’s First Mayor Dr. Peter Tschentscher laid the official foundation stone today for construction of the 100 MW electrolyzer at the site of the former Moorburg power plant.
Together with Environment Senator Katharina Fegebank, Economics Senator Dr. Melanie Leonhard, and representatives of the two project partners Luxcara and Hamburger Energiewerke, he placed a time capsule in the foundation stone on site.
The HGHH project plans to start commercial operations in the second half of 2027.
Around 10,000 tons of green hydrogen are set to be produced annually in Moorburg in future. The HGHH project is thus making an important contribution to the decarbonization of the port and industry.
Dr. Peter Tschentscher, First Mayor of the Free and Hanseatic City of Hamburg, stated the construction of the Green Hydrogen Hub in Moorburg is an important project for the energy transition in Hamburg as the production of green hydrogen is a future-oriented technology that can significantly reduce CO₂ emissions in industry and other sectors.
Dr. Melanie Leonhard, Senator of the Hamburg Ministry of Economics and Innovation, commented the switch from fossil gas to hydrogen is an important step in making industrial processes possible even as we strive to achieve our climate goals.
Katharina Fegebank, Senator of the Hamburg Ministry for Environment, Climate, Energy and Agriculture, added that the fact that the Hamburg Green Hydrogen Hub is being built on the site of the former Moorburg power plant is symbolic of Hamburg’s ambitions in the heat and energy transition.
The HGHH project received funding approval from the federal and state governments last summer. Since then, the main construction contracts have been signed. The electrolyzer was ordered from Siemens Energy in September 2024.
Simultaneously, demolition work on the former Moorburg power plant continued.
This work began in October 2023 to make room for the 100 MW electrolyzer and the connection to the hydrogen network. In summer this year, the HGHH project took over part of the construction site as planned and began initial preparatory construction work.
The building for the electrolyzer and compressors is scheduled to be completed by the middle of next year.
The green hydrogen will later be made available to customers via the HH-WIN hydrogen distribution network and the trailer loading station, which is also planned.
