VINSSEN, a maritime decarbonization technology specialist, has achieved a significant milestone in eco-friendly technology by receiving Approval in Principle (AIP) certification for Korea's first hydrogen fuel cell-powered tugboat. This accomplishment, in collaboration with KRE and the Korean Register, signifies a major advancement in applying decarbonization technology to high-carbon-emitting vessels like tugboats, contributing to the maritime industry's sustainability efforts. The hydrogen fuel cell-powered electric tugboat, with a 2,700 kW propulsion system, utilizes hydrogen fuel for operations and stores excess electricity in batteries to ensure energy efficiency across different load scenarios. VINSSEN's system optimizes hydrogen energy usage based on the tugboat's operational needs, meeting environmental regulations and delivering exceptional performance in challenging marine conditions. VINSSEN's eco-friendly propulsion system not only incorporates fuel cell technology but also integrates battery energy storage systems, offering a comprehensive green solution for port operations. This innovation positions VINSSEN at the forefront of maritime decarbonization, with a commitment to driving a sustainable future for global maritime operations. Moreover, VINSSEN's participation in Sea Asia 2025, scheduled in Singapore, highlights the company's dedication to promoting its eco-friendly vessels and propulsion systems on an international platform. With over 50 patents related to electric propulsion systems and hydrogen fuel cells, VINSSEN aims to transform diesel-powered vessels into environmentally friendly ones powered by electric and hydrogen technologies.
