Ammonia
3.7.1.
Special provisions
Both hydrous and anhydrous ammonia shall be reported jointly as 100 % ammonia.
Where CO2 from ammonia production is used as feedstock for the production of urea or other chemicals, point (b) of Section B.8.2 of Annex III shall apply.
Where a deduction of CO2 is allowed according to that section and where it would lead to negative specific embedded direct emissions of ammonia, the specific embedded direct emissions of ammonia shall be zero.
3.7.2.
Production routes
3.7.2.1.
Haber-Bosch process with steam reforming of natural gas or biogas
For that production route, direct emissions monitoring shall encompass: — All fuels directly or indirectly linked to ammonia production, and materials used for flue gas cleaning. — All fuels shall be monitored, irrespective of whether used as energetic or non-energetic input. — Where biogas is used, the provisions of Section B.3.3 of Annex III shall be applied. — Where hydrogen from other production routes is added to the process, it shall be treated as a precursor with its own embedded emissions.
Relevant precursors: separately produced hydrogen, if used in the process.
