Ammonia cracking with nickel catalyst is widely applied for on-site hydrogen generation from ammonia as a transport and storage medium. In this endothermic process, ammonia is decomposed at temperatures between 600 and 1000 °C into nitrogen and hydrogen. High-performance nickel catalysts such as ReforMax® 117 RR enable efficient ammonia decomposition with stable conversion rates and reliable long-term operation.
Typical applications include hydrogen supply for fuel cells, protective and reducing atmospheres in thermal processing, and decentralized hydrogen production in industrial plants. Because the reaction itself is CO₂-free, ammonia cracking is considered a key enabling technology for hydrogen infrastructure and the green hydrogen economy. When combined with optimized reactor design and catalyst systems, the process delivers high hydrogen purity and consistent gas quality.
Reaction: 2NH₃ → N₂ + 3H₂
