100MW electrolyser aims for 2027 launch in Hamburg
Construction of the Hamburg Green Hydrogen Hub has begun with the laying of the foundation stone for a 100MW electrolyser at the former Moorburg power plant site.
The project aims to start commercial operations in the second half of 2027 and produce around 10,000 tons of green hydrogen annually, according to the partners Luxcara and Hamburger Energiewerke.
The developers added that the hub will support the decarbonisation of the port and industry in Hamburg.
Dr. Peter Tschentscher, first mayor of the Free and Hanseatic City of Hamburg, said: “The construction of the Green Hydrogen Hub in Moorburg is an important project for the energy transition in Hamburg.”
He added: “The production of green hydrogen is a future-oriented technology that can significantly reduce CO? emissions in industry and other sectors.”
Dr. Melanie Leonhard, senator of the Hamburg Ministry of Economics and Innovation, stated: “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.”
Katharina Fegebank, senator of the Hamburg Ministry for Environment, Climate, Energy and Agriculture, said: “Hydrogen is a key component on the path to climate-neutral energy supply for our industry and large companies.”
Dr. Alexandra Bernstorff, managing partner at Luxcara, stated: “The Hamburg Green Hydrogen Hub is more than just an energy project.”
Kirsten Fust, spokesperson for the management board of Hamburger Energiewerke, said: “We are getting serious in Hamburg and moving into the implementation phase.”
The project secured federal and state funding approval last summer and has since signed main construction contracts, with the electrolyser ordered from Siemens Energy in September 2024.
Demolition work at Moorburg began in October 2023 and has cleared space for the 100MW electrolyser and its network connection, while preparatory construction this year included installing 906 vibro-compaction columns and concreting the floor slab.
The electrolyser building is scheduled for completion by the middle of next year, after which the stacks based on PEM technology will be delivered.
Green hydrogen will be supplied via the HH-WIN distribution network and a planned trailer loading station.
