In the upcoming decades, the integration of renewable energies into our continuous process routes, by producing and processing green hydrogen, is of paramount importance to combat climate change. To include green hydrogen in conventional process routes large hydrogen storages or dynamic process control strategies for hydrogen processing are needed. In this work a dynamic process control strategy for a Power-to-Ammonia (PtA) value chain is studied. A PtA process plant and respective process control strategies to adjust the plant load are conceptualized. To study the feasibility, a Haber-Bosch reactor system is modeled and implemented in MATLAB 2022b. Simulation case studies are carried out to emulate load changes. The simulation shows that the conceptualized process enables an intermittent production of ammonia based on green hydrogen. Further studies with more detailed models and refined process control strategies are planned for a detailed analysis to optimize the efficiency and flexibility of the production.
