On Wednesday 14 January, the European Maritime Safety Agency (EMSA) published two reports on the safety of hydrogen and ammonia as fuels in maritime transport. While the first involves risks that have yet to be fully assessed, the second is a viable long-term solution.
With regard to hydrogen, EMSA noted a lack of specific data on hydrogen-related failures and uncertainties concerning its suitability for maritime applications. This leads to a high level of uncertainty in the analysis of leak frequency for hydrogen fuel system installations.
In addition, activities related to the on-board hydrogen fuel system introduce new occupational risks associated with direct exposure to hydrogen and its flammable and cryogenic properties, as well as its asphyxiating effects. The crew must fully understand the risks involved in handling fuel and be familiar with the built-in safety devices. EMSA recommends that comprehensive training, operating procedures and a strong safety culture be put in place to ensure the safe operation of the vessel.
It also felt that the lack of guidelines on bunkering at berth was a major safety gap that needed to be filled.

EMSA believes that ammonia could become a viable long-term solution. However, its adoption poses significant safety and operational challenges, not least because of its toxicity, corrosiveness and the need for specialised fuel systems and engines. It is essential to address these risks through rigorous safety protocols, regulatory frameworks and flight crew training.
Valve failures are a frequent cause of incidents which, in some cases, can lead to toxic dispersion, serious injury and environmental damage. Other root causes include corrosion of pipes and equipment due to exposure to chemicals and poor maintenance.
