Bureau Veritas Marine & Offshore is actively participating in the NavHyS project, a European research initiative dedicated to advancing the use of liquid hydrogen in maritime applications to reduce carbon emissions in the shipping industry. Funded by the Clean Hydrogen Partnership, the project brings together 14 partners from across Europe with the goal of decarbonizing the shipping sector. NavHyS focuses on the ambitious deployment of below-deck Type C LH2 tanks as marine fuel for service operation vessels, addressing safety, rule development, and classification aspects. Bureau Veritas will provide three Approvals in Principle through its Design Assessment activities and lead safety research specific to liquid hydrogen in maritime environments. The project, set to run for 36 months with a €5 million EU contribution, aims to achieve Technology Readiness Level 8-9 by 2030, paving the way for the real-world deployment of liquid hydrogen-powered vessels between 2035-2040. By leveraging expertise from the space sector in cryogenic storage, NavHyS plans to revolutionize the design of service operation vessels supporting offshore wind farms with innovative concepts like 200-300 m³ storage tanks for liquid hydrogen. The coordination by ArianeGroup involves leading organizations and experts to drive technological advancements in the maritime industry. Matthieu de Tugny, President of Bureau Veritas Marine & Offshore, highlighted the commitment to supporting advanced technologies that accelerate maritime decarbonization, ensuring a safe and scalable future for hydrogen-powered vessels. Nicolas Hardouin, Program Manager at ArianeGroup, emphasized the project's disruptive innovation in liquid hydrogen fuel system design and integration into ships, leveraging space system architectures and technologies. The NavHyS project represents a significant step towards a sustainable and environmentally friendly maritime sector.
