SMR technology plays a crucial role in meeting the high hydrogen demand across sectors such as petrochemicals, refineries, and ammonia production. Its strong link with grey hydrogen production further supports its market hold as industries continue to prioritize low-cost solutions for large-scale operations. The availability of natural gas as a feedstock also strengthens the use of SMR across developed and developing economies.

By Delivery Mode Analysis

Captive delivery mode is prevalent, capturing a 73.4% segment share.

In 2024, Captive held a dominant market position in the By Delivery Mode segment of the Hydrogen Generation Market, with a 73.4% share. This dominance reflects the strong preference among industrial users to produce hydrogen on-site to meet their specific operational needs. Captive hydrogen generation offers several benefits, including reduced dependency on external suppliers, improved supply reliability, and cost savings on transportation and storage.

Industries such as petroleum refining, ammonia production, and methanol manufacturing often rely on continuous and high-volume hydrogen inputs. For these operations, having an on-site generation system ensures process efficiency and avoids the logistical complexity of delivered hydrogen. Additionally, captive systems are designed to match the exact pressure and purity requirements of the user, which enhances overall productivity.

The widespread adoption of steam methane reforming (SMR) technology further complements the captive model, as it enables cost-effective, large-scale hydrogen production using natural gas. The combination of economic advantage and customization has made captive hydrogen generation the preferred choice for large-scale industrial users.

By Application Analysis

Chemical and refinery applications lead, with a 64.6% market usage rate.

In 2024, Chemical and Refinery held a dominant market position in the By Application segment of the Hydrogen Generation Market, with a 64.6% share. This leading position is driven by the critical role hydrogen plays in refining processes and chemical manufacturing, particularly in hydrocracking, desulfurization, and ammonia production. These industries require large volumes of hydrogen to maintain continuous operations and meet stringent product specifications.

Refineries use hydrogen extensively to remove sulfur and other impurities from fuels, especially in response to global regulations for cleaner fuels. Similarly, the chemical industry, especially ammonia and methanol production, depends heavily on hydrogen as a feedstock. These applications demand a stable and uninterrupted hydrogen supply, making them key drivers of the overall hydrogen generation market.

The use of captive hydrogen generation units within these sectors has also contributed to their market dominance, ensuring reliable and cost-effective hydrogen availability. With existing infrastructure already tailored to accommodate large-scale hydrogen usage, the chemical and refinery industries remain the primary consumers in 2024.
