The Hamburg Green Hydrogen Hub (HGHH) is building a 100 MW green hydrogen electrolysis plant at the former Moorburg coal site. For this hub, Siemens Energy will supply and install six electrolyser units. Construction will start in 2025, with full operation expected by 2027, producing 10,000 tonnes of green hydrogen annually.
Furthermore, the deal includes a ten-year maintenance agreement. The stacks of the electrolyser, will be manufactured at Siemens Energy’s new gigafactory in Berlin and assembled in Mühlheim and another European location. The project is being developed by the German consortium – Luxcara and Hamburger Energieweke, and this project received Important Project of Common European Interest status in February 2024.
The project is coming up at the former Moorburg coal-fired plant, which is being partially dismantled. This will make room for the 100 MW electrolyser and the connection to the HH-WIN hydrogen distribution network.
In May 2024, Siemens Energy won a $1.52 billion deal with Energinet to enhance Denmark’s electrical grid. Over the next eight years, Siemens plans to provide transformers and switchgear for about fifty high-voltage substations. The project includes an initial phase valued at $883.29 million and it also plans to support Denmark’s goal of reaching net-zero emissions by 2045 while boosting renewable energy output by 2030.
REGlobal’s Views: Germany is expecting a significant pipeline of green hydrogen projects to be ready for commissioning over the next 3 to 4 years. The Hamburg Green Hydrogen Hub is part of the 23 projects of the third so-called Hy2Infra wave of the Important Projects of Common European Interest, which was approved by the EU Commission on February 15, 2024.
