Norwegian technology firm Pherousa has recently obtained approval in principle for its innovative onboard ammonia cracking technology from leading classification societies American Bureau of Shipping and DNV. This groundbreaking technology facilitates the conversion of ammonia into hydrogen directly onboard, offering a more efficient and practical fuel source for powering fuel cells and hydrogen-driven engines in the maritime sector. Ammonia's higher energy density and better storage capabilities compared to pure hydrogen make it an ideal hydrogen carrier for maritime applications. Pherousa also highlights the potential of its technology to replace traditional fuels with hydrogen as pilot fuels in ammonia-fuelled engines, addressing the challenges of ammonia's higher ignition temperature by using hydrogen as a pilot fuel. By incorporating hydrogen as a pilot fuel, dual-fuel ammonia ships can achieve net-zero emissions, contributing significantly to environmental sustainability in the shipping industry. The company is now focused on expanding its technology for commercial use within the shipping sector, aiming to provide cleaner and more sustainable solutions for maritime transport.
