Ammonia - Net Calorific Value
Ammonia net calorific value - relevant for bunker sizing and dual-fuel engine tuning.
NCV
18.6MJ/kg
CO₂ factor (combustion)
0.000tCO₂/tfuel
VLSFO-equivalent
45.4t
Formula, assumptions, and limits
Carbon-free at combustion - CF = 0 for IMO CII. However N₂O slip (~2 % typical) has GWP 273 → well-to-wake footprint. Toxic at 25 ppm; requires Class-approved handling.
