Despite setbacks such as Airbus postponing its hydrogen aircraft development and Arcelor Mittal delaying plans for green steel production using hydrogen, Hamburg remains focused on establishing a hydrogen economy. The city initiated the Hamburg Green Hydrogen Hub project at the Moorburg site, marked by the demolition of the coal-fired power station to pave the way for a 100 MW green hydrogen electrolysis plant. Supported by European funding, the project aims to start commercial hydrogen production in 2027 and expand to 800 MW in the future. Hamburg received over EUR 250 million in funding decisions last August to develop its hydrogen network, emphasizing the city's commitment to green hydrogen infrastructure. Collaborating with seven clusters through KLIMAready, Hamburg endeavors to drive the transition to a climate-friendly economy and industry. The city's efforts have received significant subsidies from the European Regional Development Fund and the City of Hamburg. International interest in green topics was evident in trade fairs like Hydrogen Technology Europe, emphasizing the city's potential to become a model for the networked energy transition in Germany by 2025.
