The Hamburg Green Hydrogen Hub (HGHH), a collaboration between Luxcara asset manager and Hamburger Energiewerke, has entered into an agreement with Siemens Energy to supply and install a 100-megawatt electrolyser at the former Moorburg coal-fired power plant site in Hamburg, Germany. This initiative follows funding decisions by Germany’s Minister for Economics to support important projects related to green hydrogen. Christoph Cosler from Hamburger Energiewerke expressed that the electrolyser order is a significant milestone, marking the transition from planning to implementation phase. The electrolyser, utilizing proton exchange membrane (PEM) technology suitable for renewable energy operations, is expected to commence construction in 2025 and become operational by 2027, facilitating the annual production of approximately 10,000 tonnes of green hydrogen at the Moorburg site. The hydrogen produced will be distributed through the HH-WIN network and a lorry-loading station. The HGHH consortium intends to engage companies from diverse sectors and is currently in negotiation processes. This large-scale project is viewed as a crucial advancement in the European hydrogen sector, vital for the success of the energy transition, as stated by Alexey Ustinov, Head of Sustainable Energy Systems at Siemens Energy. The project's significance lies in the promotion of green molecules like hydrogen, emphasizing the necessity of such initiatives in achieving sustainable energy goals.
