How to Use This Calculator

Enter Ammonia Input (kg), Cracking Efficiency (%), and Purification Loss (%).
Set Energy Input (kWh).
Review the Hydrogen Yield (kg) result.
Use Energy Content (kWh) and Conversion Ratio (kg H₂/kg NH₃) to inform your decision.
Use the chart to visualize the results and explore different scenarios by adjusting inputs.

How the result changes with Ammonia Input (kg)

Ammonia Input (kg): Mass of ammonia (NH₃) to be cracked into hydrogen.
Cracking Efficiency (%): Thermal decomposition efficiency. Modern crackers achieve 85-95%.
Purification Loss (%): Hydrogen lost during purification (PSA or membrane) to remove residual NH₃ and N₂.
Energy Input (kWh): Total energy required for cracking and purification.

Net Energy Balance: Positive = energy surplus, negative = net energy consumer.
