Ammonia is a promising solution for long-distance and carbon-free storage and transportation of hydrogen. However, the decomposition of NH3 into hydrogen and nitrogen is energy-intensive, especially at elevated pressures. This paper presents a high throughput approach to accelerate catalyst screening and process optimization for NH₃ cracking. A 16-fold parallel fixed-bed reactor setup with was upgraded toward NH₃ processing. Validation was conducted using an in-house Fe-based catalyst, demonstrating the unit's capabilities and enabling the generation of kinetic data sets. This innovative approach not only accelerates catalyst assessment but also contributes to energy-efficient NH₃ cracking processes for hydrogen production. High throughput technology enables rapid testing of diverse catalysts, addressing the growing demand for hydrogen.
