A consortium led by ArianeGroup has initiated a groundbreaking project named NAVHYS to explore the use of liquid hydrogen (LH2) as an energy carrier in maritime transport. The project focuses on developing solutions for storing and utilizing LH2 in a zero-emission service operation vessel (SOV) designed for offshore wind farms. Collaborating with eleven partners from diverse fields such as space industry, shipbuilding, and energy, the project aims to integrate an innovative below-deck LH2 storage and fuel system into the SOV, which will be designed by Vard for North Star, a shipping company. The NAVHYS project also includes obtaining approval in principle from Bureau Veritas for the vessel design. Marie-Sophie Nizou, the Program Manager at ArianeGroup and Coordinator of NAVHYS, emphasized the significance of liquid hydrogen for shipping, particularly its energy density benefits for long-distance transport. The project addresses the technological challenge of storing LH2, which requires tanks capable of maintaining extremely low temperatures. Partners in the project will contribute expertise in areas like safety, hazard analysis, technology scale-up, and fuel tank design. Supported by the Clean Hydrogen Partnership and co-funded by the European Union, NAVHYS aims to accelerate the decarbonization of the maritime sector by integrating liquid hydrogen tanks into vessels. Valérie Bouillon-Delporte, the Executive Director of the Clean Hydrogen Partnership, expressed pride in supporting this pioneering project, highlighting its role in promoting clean hydrogen technology and driving the energy transition. The NAVHYS project aligns with the partnership's mission to advance innovations that enhance the competitiveness of European companies while contributing to decarbonization efforts. The introduction of the NAVHYS project comes as a significant development in the use of liquid hydrogen as an energy source for maritime applications. This project, along with other initiatives like Louis Dreyfus Armateurs' SOV concept using liquid hydrogen, signifies a promising shift towards leveraging clean energy sources and cutting-edge technology in the maritime industry.
