Hydrotreating remains the leading application for hydrogen in refineries in 2025, primarily to remove impurities and produce ultra-low sulfur fuels that align with global clean air mandates. Hydrocracking is the second largest application, enabling refineries to break down heavy fractions into lighter, more valuable products. Desulfurization and chemical synthesis are notable as well, driving refiners toward higher hydrogen consumption. The ongoing refinement in catalytic processes and tightening regulatory requirements ensure a consistently high share for hydrotreating and hydrocracking applications.
