How is AI transforming petroleum refining hydrogen operations?

Artificial Intelligence (AI) is playing an increasingly pivotal role in optimizing hydrogen production and refining efficiencies. Honeywell’s Protonium technology, launched in 2025, harnesses AI and machine learning to improve electrolyzer and plant design efficiency, exemplified by its implementation at the Mid-Atlantic Clean Hydrogen Hub in the U.S. Similarly, TotalEnergies leverages AI-driven digital twins in Europe to enhance operational accuracy and integrate green hydrogen into petrochemical workflows. AI frameworks such as AceWGS further accelerate catalyst innovation, contributing to cleaner and more effective refining processes.

What factors are driving the market’s impressive growth and what challenges does it face?

The market growth is stimulated by stringent regulations for fuel quality, refinery expansions, and increasing investments in cleaner hydrogen technologies such as electrolysis for green hydrogen. However, economic considerations present significant hurdles.

Transitioning from grey hydrogen to low-emission hydrogen sources like green or blue hydrogen is capital intensive and risky for refiners, slowing widespread adoption. European refiners face subsidy uncertainties, leading some to pause green hydrogen projects.

Market Scope

What are the emerging opportunities and trends within the petroleum refining hydrogen market?

• Why is electrolysis gaining momentum in hydrogen production?
  Driven by decarbonization efforts and regulatory emphasis on clean hydrogen, electrolysis is the fastest-growing production method segment, especially among small and medium-sized refineries.

• How are refining processes evolving with hydrogen usage?
  While hydrocracking remains dominant, hydrotreating is witnessing rapid growth due to its effectiveness in removing impurities and meeting ultra-low sulfur fuel standards.

Regional and Segmentation Analysis

The Asia Pacific region leads the market, supported by refinery modernization and government backing for hydrogen projects, with China serving as a major growth engine. North America follows as the fastest-growing area due to its expansive refinery capacity, rigorous regulations, and substantial government support for low-carbon hydrogen initiatives.

Production Process Segmentation

• Steam Methane Reforming (SMR): This process dominates the market, holding approximately 75% of the share in 2024, due to its proven effectiveness, cost-efficiency, and widespread use in large refineries. SMR primarily produces grey hydrogen, which accounts for the majority of hydrogen used in the industry.

• Electrolysis: The fastest-growing segment, expected to witness significant expansion during the forecast period. Driven by decarbonization efforts and increasing investment in green hydrogen technologies, electrolysis offers environmentally friendly hydrogen production from renewable energy sources. Notable projects in Europe and North America exemplify this growth.

Application Segmentation

• Hydrocracking: The hydrocracking segment led the market with a 35% share in 2024. This process converts heavy crude oil fractions into valuable, cleaner fuels such as diesel, jet fuel, and gasoline, making it essential for modern refineries.

• Hydrotreating: A rapidly expanding application responsible for removing sulfur and other contaminants from fuels to meet stringent environmental standards like IMO 2020 and Euro 6.

• Fluid Catalytic Cracking (FCC): Also significant, this process utilizes hydrogen to maximize the yield of lighter, high-value products from crude oil.

Type Segmentation

• Merchant Hydrogen: Hydrogen supplied by third-party providers, used broadly across refineries, especially in small to medium-sized facilities.

• Captive Hydrogen: Hydrogen produced and utilized within the same refinery or chemical plant, generally through onsite reforming units.

End-Use Industry Segmentation

• Petroleum Refining: The primary end-user, accounting for about 60% of hydrogen consumption. Large, complex refineries require vast amounts of hydrogen for desulfurization, hydrocracking, and other processes.

• Chemical & Petrochemical Production: Contributing approximately 20%, where hydrogen acts as a feedstock for ammonia, methanol, and other chemicals.

• Energy Transition & Low-Emission Fuels: Growing segment with increasing focus on low-carbon hydrogen solutions for sustainable fuels and decarbonized processes.
