Outline
Ammonia synthesis based on hydrogen derived from renewable electricity (i.e. green hydrogen and green ammonia process) is frequently fluctuated due to weather change and the sections are highly coupled. To understand the synthesis and scheduling of power generation and transmission, hydrogen production by water electrolysis, hydrogen storage, electrochemical energy storage, and ammonia synthesis sections in green ammonia process, a generic process model for both steadystate and dynamics mode was developed using the next generation process simulation software, AVEVA Process Simulation, and the dynamics response of the model to weather fluctuation was investigated by means of multisteady state simulation. The results show that optimized design and scheduling of the hydrogen storage and electricity storage modules can significantly stabilize the ammonia production, utilize excess renewable electricity, reduce grid power input, and thus, improve the economy.
