The Port of Gothenburg recently conducted a trial utilizing hydrogen-powered generators to supply electricity for shore power to Stena Line vessels. The generators, fueled by green hydrogen, supported the Stena Germanica and Stena Scandinavica ships while docked. This initiative aimed to explore the feasibility and benefits of using hydrogen in the maritime industry. While questions were raised about why direct renewable electricity was not utilized, hydrogen was chosen for its energy storage capabilities and flexibility. The Port of Leith in Scotland has also ventured into green hydrogen for shore power generation, emphasizing its advantages in grid management. By producing green hydrogen during surplus renewable electricity periods, it ensures a balanced grid and reliable power supply, even when renewable sources are not actively generating electricity. This innovative approach highlights the potential of hydrogen as a sustainable energy solution in the maritime sector, offering both environmental and operational benefits.
