Optimal Scheduling of a Tri-Generation Plant for Blue Ammonia, Hydrogen, and Power

As the world's energy demand grows and fossil fuels become increasingly burdensome, governments and stake-holders have recognized the importance of reducing carbon dioxide emissions to combat climate change. Hydrogen has been identified as a crucial component of successful decarbonization efforts. However, because hydrogen has a low density, it must typically be compressed at high pressures or liquefied in order to be transported and stored effectively. This study introduces a new method for generating compressed hydrogen, ammonia, and electricity through a multigeneration process. The process involves using a catalytic membrane reactor to recover hydrogen, while simultaneously capturing all CO2 through a membrane. The process also incorporates a high-temperature solid oxide fuel cell for efficient heat and electricity integration. Furthermore, the study presents an optimization model for the multigeneration process that helps to identify the most effective operational production patterns for generating hydrogen, ammonia, and electricity. Optimization is performed on an hourly basis for a duration of one week. According to the findings, the production of hydrogen is deemed to be the most beneficial among the three options, followed by ammonia, then electricity.
