The Port of Gothenburg is pioneering an innovative pilot project that utilizes a mobile hydrogen generator to provide electricity to ships while they are docked, subsequently reducing carbon dioxide emissions. This project aims to offer an alternative solution in cases where traditional On-shore Power Supply systems are not feasible. Stena Line's terminals at the port were among the first globally to adopt shore power for ships, and this new hydrogen-based approach showcases a step further in emission reduction efforts. The project, which recently entered its final stage, connected a hydrogen-powered generator to the existing shore power setup at the port's Germany terminal, successfully powering docked vessels. The initiative has received positive feedback from stakeholders, emphasizing the importance of exploring cleaner energy options in the maritime sector. This development aligns with upcoming EU regulations that mandate the use of shore power by 2030 for vessels, potentially leading to a significant reduction in CO₂ emissions. The hydrogen generator, developed by Hitachi Energy and powered by green hydrogen from Linde Gas, signifies a crucial step towards sustainable port operations. The collaboration between various companies, including PowerCell Group and Stena Line, highlights the collective effort to transition towards cleaner energy solutions. Furthermore, the versatility of the HyFlex generator extends beyond maritime operations, with potential applications in construction and other industries. Hydrogen technology is gradually gaining traction within the Port of Gothenburg, as evidenced by the deployment of hydrogen refueling stations and testing of hydrogen-powered vehicles. The positive results from the hydrogen trial showcase the feasibility and effectiveness of such solutions in reducing carbon emissions. As the maritime industry strives to mitigate its environmental impact, projects like these serve as promising examples of innovative and sustainable practices.
