The Hydrotug 1, the world's first hydrogen-powered tug, has been built for an experienced Belgian owner, showcasing a groundbreaking development in sustainable maritime operations. The tug is equipped with dual-fuel engines, enabling it to run on both hydrogen and traditional marine fuel, thereby significantly reducing CO2 emissions and advancing cleaner port operations. It also integrates compressed hydrogen storage systems for safe and efficient operation in demanding harbour environments, alongside state-of-the-art emissions control technologies to ensure compliance with environmental regulations. Ricardo Garcia, Group Commercial Director at Armon Shipyard, emphasized the tug's role in demonstrating the practical application of hydrogen technology in a high-power workboat setting, a feat previously limited to prototypes or smaller vessels. This pioneering vessel not only represents a major step towards decarbonisation efforts in the maritime sector but also paves the way for a more sustainable future in maritime operations.
