Bureau Veritas Marine & Offshore (BV) has announced its participation in NAVHYS, a European research project dedicated to advancing the use of liquid hydrogen (LH2) in maritime applications. Funded by the Clean Hydrogen Partnership, NAVHYs was initiated by the Ariane Group, leveraging their experience with LH2 as a fuel for Ariane rockets. The project's primary focus is on developing innovative solutions for storing and utilizing liquid hydrogen as an energy carrier in maritime transport, with an initial emphasis on hydrogen-fueled Service Operation Vessels (SOVs). BV has actively contributed to the project proposal and consortium structure, bringing expertise in safety, rule development, and classification to support innovation in hydrogen-fueled vessels. One key technical aspect NAVHYs is addressing is the utilization of below-deck Type C LH2 tanks as marine fuel for SOVs, with envisioned storage tanks of 200-300 cubic meters and the capacity to carry 12-18 tonnes of liquid hydrogen. BV will issue three Approvals in Principle (AiPs) through its Design Assessment activities, covering the liquid hydrogen storage system, fuel system, and their integration into an SOV. Additionally, BV will lead safety research and rule development tailored to liquid hydrogen in maritime settings. The project will explore shore-based hydrogen supply solutions and the lifecycle of hydrogen-fueled vessels. Formally launched in January 2025, NAVHYS is expected to achieve Technology Readiness Level (TRL) 8-9 by 2030, facilitating real-world deployment of hydrogen-powered vessels between 2035 and 2040. Bureau Veritas Marine & Offshore's president, Matthieu de Tugny, expressed pride in supporting the NavHyS project to address challenges related to liquid hydrogen deployment in shipping, emphasizing a commitment to innovative technologies for maritime decarbonization. According to Nicolas Hardouin, program manager at ArianeGroup, the project's design of the liquid hydrogen fuel system and its integration below deck in the ship signify a significant innovation compared to past maritime projects.
