Hamburg Green Hydrogen Hub has commissioned Kraftanlagen to construct the infrastructure for 100 MW electrolyzer

The contract covers the planning, delivery and construction of all ancillary technical and supply facilities for the project. These include power distribution and water treatment facilities, cooling and compressor stations, and connections to the hydrogen network and trailer loading station. This will allow for greater flexibility in transporting the produced green hydrogen.

Once the building complex has been completed, work is scheduled to begin in early 2026, with the aim of commissioning the plant infrastructure by the second half of 2027. This will enable Kraftanlagen to lay the essential foundations for integrating the 100 MW electrolyzer from Siemens Energy into the site and ensuring reliable future operation.

Preparatory construction work to stabilize the subsoil on the 16,000-square-meter HGHH site began in June. Around 10,000 tons of green hydrogen are set to be produced annually in Moorburg in future and will be made available to customers via connection to the HH-WIN distribution network and the trailer loading station.

Holger Matthiesen, Managing Director at HGHH and Director of Offshore Wind & Green Hydrogen at Luxcara, says: “We are delighted to have gained Kraftanlagen as an experienced partner from Germany, who will support us with their expertise in implementing this pioneering project for the green hydrogen economy in Hamburg, as well as building and commissioning the electrolyzer and ancillary systems.”

Heinrich Dauer, Head of the Energy Business Unit at Kraftanlagen, emphasizes: “We are very proud to be implementing this project and supporting HGHH in realizing its vision. We will contribute our many years of expertise in power plant and plant construction to ensure the project’s success. Moorburg, as a flagship project of the energy transition, embodies our shared vision for a green future.”

The HGHH project
The Hamburg Green Hydrogen Hub (HGHH) project consists of two partners: Luxcara (74.9%) and Hamburger Energiewerke (25.1%). The consortium is constructing a 100 MW electrolysis plant for green hydrogen on the site of the former Moorburg coal-fired power plant in Hamburg. Commercial operation is expected to begin in 2027, with the facility set to produce around 10,000 tons of green hydrogen annually. This project will
make a significant contribution to the decarbonization of the port, industry and transport sectors.
