Norwegian shipbuilder Vard has announced its collaboration with the European project NAVHYS to develop a groundbreaking design of a service operation vessel (SOV) that will operate with zero emissions, powered by liquid hydrogen. This project, spearheaded by the aerospace company the ArianeGroup, involves a consortium of 11 partner companies working towards creating innovative solutions for the storage and utilization of liquid hydrogen on a seagoing vessel. The SOV, which is being designed for the North Star Group in the UK, will feature a liquid hydrogen storage and fuel system that will undergo approval from Bureau Veritas. The primary objective of the NAVHYS project is to introduce a revolutionary concept for a below-deck LH2 storage and fuel system on an SOV, with the vision of presenting a fully decarbonised maintenance solution for wind energy service providers. By focusing on enhancing energy efficiency and minimizing the environmental footprint, NAVHYS aims to contribute significantly to the advancement of hydrogen fuel systems in maritime applications. Supported by the European Union, the partnership between Vard and NAVHYS signifies a crucial step towards sustainable and eco-friendly maritime operations. The collaboration underscores a commitment to innovation and environmental stewardship, highlighting the potential of hydrogen as a clean energy source in the shipping industry. Through this initiative, the project partners aim to set a precedent for future developments in the field of hydrogen-powered vessels, paving the way for a more sustainable and greener maritime sector.
