Cover Story: To achieve a decarbonisation transition of the energy mix, renewable ammonia is seen as an important option in the transport and energy sectors. A green ammonia synthesis system was designed, modeled, and simulated in the study. The results show that at a recirculation ratio of 70%, the system’s annual total energy consumption is 426.22 GWh, with annual ammonia production reaching 8342.78 t. The optimal system configuration comprises seven 12 MW offshore wind turbines, integrated with a 460 MWh lithium battery and 240 t of hydrogen storage capacity. At this configuration, the LCOE costs approximately GBP 5956.58/t. It shows that incorporating renewable energy can significantly reduce greenhouse gas emissions, but further optimisation of energy storage configurations and reaction conditions is needed to lower costs.
