To drive the defossilization of economies worldwide and achieve the Paris Climate Goals, it is crucial to produce large amounts of sustainably generated hydrogen (H2) and store it efficiently and cost-effectively. For Europe, as an energy-importing continent, the transition from fossil to green energy carriers holds central importance. Ammonia (NH3), a carbon-free energy carrier that can be easily liquefied, offers an efficient and cost-effective transport option in numerous scenarios, especially considering the existing ship and port infrastructure for industrial quantities. A significant extension of application possibilities for imported green NH3 is its conversion back into H2 through catalytic reforming, also known as cracking or decomposition. In this presentation, a comprehensive overview of the current status of global ammonia-to-hydrogen projects will be delivered, emphasizing large-scale constructions for harbors and maritime transportation applications.
