How does a resilient, flexible ammonia process look? Robust design optimization of a Haber-Bosch process with optimal dynamic control powered by wind

Ammonia can be an essential energy vector for storing excess renewable during the year and release this when demand is high. This storage provides part in sector moments there not enough wind sun to cover demand. Although Haber-Bosch a very mature process synthesize hydrogen nitrogen ammonia, it flexible match erratic nature of renewables. mismatch creates need large intermediate buffer tanks. To reduce capacity tank, we optimize dynamic power-to-ammonia minute time scale while considering uncertainties linked Therefore, coupled stochastic power Power-to-Ammonia performed design optimization under uncertainties, i.e. robust optimization, three-hour scenario optimal control. The showed significant trade-offs between most productive, flexible, resilient, plant designs. For productive designs, bypass fraction feed have roles achieving these In future, will use consider uncertainty over more extended periods (days, weeks months) with investigate its effect on size plant’s cost.
