A study by the Fraunhofer Centre for Maritime Logistics and Services (CML) reveals Hamburg's potential to become Germany's hydrogen hub by 2045. The Port of Hamburg is projected to play a crucial role in meeting up to 18% of the country's hydrogen demand, aligning with Germany's aim for greenhouse gas neutrality. The analysis emphasizes the importance of suitable waterside infrastructure, ample space, and the ability to handle import volumes of green hydrogen and derivatives like ammonia and methanol. With rising production and seaborne imports expected, the study suggests the need for constructing new liquid bulk terminals, including the Sustainable Energy Hub (SEH) zone, and repurposing the Moorburg coal-fired power plant into the 'Hamburg Green Hydrogen Hub.' Hamburg's role in green energy imports is further underlined by recommendations to enhance transport infrastructure and connect to the Hydrogen Backbone Europe network. Despite the identified potential, the study acknowledges the challenges of entrepreneurial implementation. Hamburg's strategic positioning and existing infrastructure set the stage for its significant contribution to Germany's green energy transition.
