Hydrogen and decarbonation training

Aimed at shipping personnel, paramaritime professionals, merchant navy officers and engineers.

No pre-requisites

• Gain an in-depth understanding of hydrogen and decarbonisation strategies in maritime transport, including the properties of hydrogen, its production, and its use as an alternative fuel, as well as examining other alternative fuels such as methanol and ammonia.
• Explore in detail the international regulations and standards applicable to hydrogen and other alternative fuels in the maritime sector, addressing aspects of safety, storage, and distribution.
• Examine existing and emerging technologies related to the use of hydrogen and other alternative fuels, focusing on their advantages, disadvantages, and practical applications in the context of decarbonisation.
• To develop an understanding of the risks associated with the use of hydrogen (gaseous and liquid) and other alternative fuels, integrating strategies to control these risks through the analysis of typical incidents and accidents.
