In 2024, the shipping industry continued its push towards lower emissions with 600 vessels ordered for alternative fuels, expanding the total orderbook to 1,737 vessels. The in-service alternative-fuelled fleet also saw growth, reaching 1,860 vessels. Methanol-fuelled vessels led the way in new fuel orders, followed by a significant surge in ammonia-fuelled vessel orders. Projects and advancements in ammonia technology were highlighted, emphasizing the industry's commitment to decarbonisation. Hydrogen fuel also gained traction with orders for 12 vessels, including hydrogen-powered passenger ferries. Efforts in LNG and LPG were noteworthy, with a focus on reducing methane emissions. While progress is evident, uncertainties remain around the availability and cost of zero-emission fuels. The industry's readiness for future fuels, potential for public interventions to scale up production capabilities, and the importance of stable markets were emphasized. Initiatives like the Maritime Fuel Supply Dialogues aim to drive regional fuel supply development at scale for maritime decarbonisation.
