 Some key parameters for the energy performance of a green ammonia plant include:

Levelized cost of ammonia (LCOA): A key performance indicator (KPI) that can be used to evaluate the plant's performance 

Hydrogen load factor (HB LF): A KPI that can be used to evaluate the plant's performance 

Energy intensity: The global average energy intensity of ammonia production is around 41 GJ/t, while the best available technology (BAT) energy performance levels are 28 GJ/t for natural gas-based production and 36 GJ/t for coal-based production 

System efficiency: The power-to-ammonia process can achieve a system efficiency of over 74% 

Heat utilization: Steam cycles with three pressure levels can maximize heat utilization at the system level 

Other factors that can impact the energy performance of a green ammonia plant include:

Renewable energy sources: The use of renewable energy sources, such as wind and solar, can help reduce the cost of the plant 

Operational improvements: Improving the performance of existing equipment can help reduce emissions 

Process changes: Structural shifts in the processes used to produce ammonia can help reduce energy intensity
