The global transition toward a low-carbon economy identifies hydrogen (H2) as a fundamental energy vector. However, critical challenges related to long-distance storage and transport limit its implementation on a global scale. In this context, ammonia (NH3) emerges as a strategic hydrogen carrier due to its high volumetric hydrogen density, ease of liquefaction, and well-established global logistics infrastructure. This thesis analyses the process design and simulation in Aspen Plus of a catalytic ammonia cracking process to produce 5 tons/day of high-purity hydrogen (99.9%). Given the strongly endothermic nature of the reaction, the study focuses on comparing two heat supply strategies: conventional thermal heating via combustion and electrical heating.
