Construction has begun on the Hamburg Green Hydrogen Hub, marked by the laying of the foundation stone for a 100-megawatt electrolyser at the former Moorburg coal plant site, project partners Luxcara and Hamburger Energiewerke said.
The developers expect commercial operations to begin in the second half of 2027, with the facility projected to produce about 10,000 tonnes of green hydrogen each year. They said the hub is intended to support the decarbonisation of Hamburg’s port and industrial sectors.
Dr Peter Tschentscher, first mayor of the Free and Hanseatic City of Hamburg, said the project signals a significant step in the region’s energy shift. “The construction of the Green Hydrogen Hub in Moorburg is an important project for the energy transition in Hamburg,” he said. “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 at the Hamburg Ministry of Economics and Innovation, said the initiative aligns with the city’s industrial priorities. “The industrial heart of our city beats in the port – and this is precisely where we are helping to ensure that hydrogen will be produced in the future for the climate-neutral energy generation of tomorrow,” she said.
Katharina Fegebank, senator for environment, climate, energy and agriculture, said hydrogen would become essential for the region’s decarbonisation efforts. “Hydrogen is a key component on the path to climate-neutral energy supply for our industry and large companies,” she said.
Luxcara managing partner Dr Alexandra Bernstorff described the scheme as broader than a single infrastructure development. “The Hamburg Green Hydrogen Hub is more than just an energy project,” she said.
Kirsten Fust, spokesperson for the management board of Hamburger Energiewerke, added: “We are getting serious in Hamburg and moving into the implementation phase.”
The project secured federal and state funding approval last summer. Main construction contracts have since been signed, and Siemens Energy was selected in September 2024 to supply the electrolyser. Demolition of the Moorburg site began in October 2023, clearing space for the 100 MW installation and its grid connection.
Preparatory works this year included the installation of 906 vibro-compaction columns and the concreting of the floor slab. The electrolyser building is due for completion by mid-2026, after which PEM-based stacks will be delivered.
The hydrogen produced will be fed into the HH-WIN distribution network and a planned trailer loading station, the developers said.
