Hydrogen production from ammonia: Catalytic pathways and reactor technologies

Poster Abstract: Ammonia (NH₃) is increasingly recognized as a practical hydrogen carrier for the low-carbon energy transition, combining a high volumetric hydrogen density with mature production, storage and transport infrastructure. Converting stored ammonia back into usable hydrogen, however, requires catalytic decomposition (cracking) steps that remain limited by reaction kinetics, energy demand and downstream purification needs. This work reviews the catalytic and reactor engineering strategies currently shaping the ammonia-to-hydrogen conversion route, with emphasis on technologies capable of delivering fuel-cell-grade hydrogen.
