Hamburg's Hydrogen Leap: From Coal to Clean
Hamburg, Monday, 1 December 2025.
Hamburg has kicked off its Green Hydrogen Hub, transforming an old coal plant into a 100 MW electrolyzer site. This project aims to produce 10,000 tons of hydrogen annually by 2027, supporting climate goals.
A New Chapter in Hamburg’s Energy Story
The Hamburg Green Hydrogen Hub (HGHH) is officially underway, transforming the site of the old Moorburg coal-fired power plant into a symbol of the city’s sustainable future. With the foundation stone laid by Hamburg’s First Mayor, Dr. Peter Tschentscher, the project paves the way for a 100 MW electrolyzer to start producing green hydrogen by 2027. This facility is expected to generate around 10,000 tons of hydrogen annually, significantly contributing to Hamburg’s climate goals and supporting the decarbonization of the port and local industries [1][2].
Partnerships Powering the Hydrogen Revolution
The HGHH is a collaborative effort between Luxcara and Hamburger Energiewerke, with Luxcara holding a majority stake of 74.9%. The project is supported by both federal and state funding, highlighting the importance of public-private partnerships in driving the energy transition. The electrolyzer, essential for hydrogen production, was ordered from Siemens Energy and is part of a broader strategy to integrate green hydrogen into Hamburg’s industrial processes [2][3][4].
From Coal to Green: Transforming Moorburg
Once a site of coal combustion, Moorburg is now at the heart of Hamburg’s clean energy future. The demolition of the old power plant began in October 2023, with significant groundwork completed to prepare for the installation of the electrolyzer. This transformation is a testament to the city’s commitment to sustainable development and its strategic use of existing infrastructure to support new technologies [3][5].
Looking Ahead: The Future of Hydrogen in Hamburg
As Hamburg positions itself as a leader in the hydrogen economy, the HGHH serves as a catalyst for further advancements in green energy. The project not only aims to meet local energy needs but also to establish Hamburg as a key player in the European hydrogen network. With the production set to commence in the latter half of 2027, all eyes are on this ambitious initiative to see how it shapes the future of energy in the region [1][4][6].
