Marine specialist Vinssen has achieved an Approval in Principle (AiP) in South Korea for the country's first hydrogen-powered tugboat. The certification was awarded by the Korean Register for a tugboat equipped with a 2,700kW hydrogen fuel cell that can store excess electricity in batteries for low-load operations. During high-demand scenarios, the stored energy complements the fuel cell's power, ensuring stable and efficient propulsion. Vinssen highlighted the vessel's eco-friendly propulsion system, designed to optimize hydrogen energy usage and comply with environmental regulations while maintaining high performance in marine environments. This project, resulting from a Memorandum of Understanding with KRE, showcases innovation in the marine industry. The development of a hydrogen-powered leisure boat in South Korea further demonstrates the country's commitment to sustainable marine technology. Similarly, in the US, Amogy achieved success by retrofitting a tugboat with a hydrogen power system, contributing to zero-emission marine transportation. These advancements underscore the global shift towards eco-friendly marine operations and the growing role of hydrogen technology in the sector.
