1. System Boundaries
3.6 Hydrogen
3.6.1 Special provisions
Only the production of pure hydrogen or mixtures of hydrogen with nitrogen usable in ammonia production shall be considered. Not covered are the consumption of synthesis gas or of hydrogen as precursor within refineries or organic chemical installations, where hydrogen is exclusively used within those plants and not used for the production of goods listed in Annex I to Regulation (EU) 2023/956.
3.6.2 System boundary
3.6.2.1 Steam reforming and partial oxidation
For those production routes, direct emissions monitoring shall take into account:
– all processes directly or indirectly linked to hydrogen production and the separation of hydrogen and carbon monoxide, and flue gas cleaning;
– all fuels used in the hydrogen production process irrespective of their energetic or non-energetic use, and fuels used for other combustion processes including for the purpose of producing hot water or steam.
3.6.2.2 Steam cracking
For that production route, direct emissions monitoring shall take into account:
– all processes directly linked to hydrogen production;
– all processes directly or indirectly linked to the production processes, and from flue gas cleaning.
