Norway, March 13 -- DNV has delivered the European Maritime Safety Agency (EMSA) commissioned multi-year study "Safety of hydrogen for use in ships," culminating in a final report and a non?mandatory guidance document. The study concludes that design-based safety is required for hydrogen-fuelled ships and recommends secondary enclosures across all hydrogen carrying components, including on open deck.Hydrogen is emerging as a potential fuel option for shipping, but wider uptake is expected to take time. The study shows that hydrogen hazards differ from those of other alternative marine fuels such as LNG. Even smaller leaks can quickly form ignitable gas clouds, and combined with hydrogen's low ignition energy and challenges associated with l...
