Summary
The hydrogen (H2) production source category consists of process units that produce H2 by reforming, gasification, oxidation, reaction, or other transformation of feedstock, and that sell the H2 as a product. H2 production units that are located at a petroleum refinery are included in this source category if they are not owned by or under the direct control of the refinery owner. Greenhouse has (GHG) emissions from H2 production units other than catalytic reforming units that are owned by a petroleum refinery subject to Subpart Y (Petroleum Refineries) must be reported according to the provisions of Subpart P.
