Dynamic Simulation of a Novel Small-scale Power to Ammonia Concept

Ammonia is a promising energy vector and storage means for hydrogen. Power to ammonia (P2A) processes employ renewable energy to split water to provide the hydrogen for the Haber-Bosch ammonia synthesis. The fluctuating nature of the renewables requires a good dynamic behavior of these cycles.Employing the software Aspen Plus Dynamics(r), this paper investigates the dynamic behavior of a novel containerized P2A solution, which is going to be tested at the University of Genova in 2023.The simulation results of the start-up, various load changes and the shutdown of the process suggest that the control architecture can handle all cases in a satisfactory way.However, there seems to be room for improvement regarding the parameters of some controls.
