Classification society Bureau Veritas Marine & Offshore (BV) has announced its participation in NavHyS, a new European research project focused on advancing the use of liquid hydrogen (LH2) as marine fuel, specifically targeting below-deck Type C LH2 tanks for service operation vessels (SOVs). The project, funded by the Clean Hydrogen Partnership and led by ArianeGroup, aims to develop innovative liquid hydrogen storage systems, fuel systems, and integration methods for SOVs. BV will provide three Approvals in Principle (AiPs) and lead safety research specific to liquid hydrogen in maritime environments. The initiative also includes examining shore-based hydrogen supply solutions and the lifecycle of hydrogen-fueled vessels. NavHyS, launched in January 2025, is expected to achieve a Technology Readiness Level (TRL) of 8-9 by 2030, paving the way for real-world deployment of hydrogen-powered vessels between 2035-2040. By leveraging the expertise of the space sector in cryogenic storage, NavHyS aims to revolutionize the design of SOVs supporting offshore wind farms with advanced hydrogen storage capabilities. The envisioned storage tanks are expected to carry 12-18 tonnes of liquid hydrogen with bunkering capabilities of 10 tonH2/hour and autonomous operation for up to 10 days. Bureau Veritas expressed pride in its involvement in the project, emphasizing its dedication to supporting technological advancements for maritime decarbonization and the future of hydrogen-powered ships. The collaboration between industry leaders in space systems and maritime design is set to drive significant innovation in the field of sustainable shipping.
