DNV has released a competence standard (ST) for methanol and a recommended practice (RP) for ammonia, to enable crew and shipowners to tackle the safety risks and challenges posed by the introduction of new alternative fuels and technologies through shipping’s decarbonization.While new fuels and technologies are key to achieving maritime decarbonization, their adoption necessitates robust safety and competence frameworks.According to DNV’s Alternative Fuels Insights platform,…

Researchers at Stanford University and King Fahd University of Petroleum and Minerals in Saudi Arabia have developed a prototype device that can produce ammonia using wind energy to draw air through a mesh.The approach is an alternative to the traditional method that produces ammonia by combining nitrogen and hydrogen at high pressures and temperatures. This existing method consumes 2% of global energy and contributes 1% of annual carbon dioxide emissions from its reliance on natural gas.The study…

In light of the evolving regulatory landscape for ammonia as a maritime fuel, and the recent finalization of the IMO’s draft interim guidelines on ammonia, the International Association of Classification Societies (IACS) has withdrawn Unified Requirement UR H1, “Control of Ammonia Releases in Ammonia Fuelled Vessels.”The news comes ahead of its scheduled implementation date of January 1, 2025. IACS says the decision stems from the differences between its safety parameters and those outlined in the IMO Interim Guidelines.
