Ammonia Fuel - NOx + N₂O Slip
Estimated NOx + N₂O emissions per kWh for ammonia-fuelled engines - drives well-to-wake GHG footprint.
NOx produced
1.500t
N₂O slip
0.0080t
N₂O → CO₂eq (GWP 273)
2.18t
Formula, assumptions, and limits
$$\text{GHG} = m_{N_2O} \cdot 273$$
N₂O GWP 273 (AR6 100-yr) makes 0.1 g/kWh slip equivalent to ~27 g/kWh CO₂ - meaningful on a carbon-free fuel. SCR + ammonia-slip catalyst (ASC) needed to cut NOx below Tier III.
