The Hydrogen Supply Chain Nobody Talks About

How a System Built for Oil Refineries Quietly Supports Dozens of Modern Industries

Hydrogen is frequently described as the fuel of the future.  It appears in conversations about clean transportation, steel decarbonization, energy storage, and semiconductor manufacturing.  Governments are investing billions of dollars in hydrogen hubs, as well as incentives, tax credits, grants and funding for hydrogen projects in certain regions.  Vehicle makers continue exploring hydrogen mobility. Industrial leaders are discussing hydrogen as a cornerstone of the low carbon economy.

Yet very few people understand how the hydrogen economy actually works today.

The modern hydrogen supply chain was not built for transportation, energy storage, or distributed industrial demand.  It was built primarily to serve oil refineries, chemical, plastics and fertilizer production.  Most of the hydrogen produced in the United States and around the world is generated for these sectors.  The petrochemical industry produces some hydrogen; however, a refinery can either be a net hydrogen producer or a net hydrogen consumer depending on the type of feedstock being refined.  Everything else, from semiconductor manufacturing to rocket launches to hydrogen forklifts, often relies on excess capacity from this refinery, petrochemical and fertilizer-oriented system.

This reality creates a structural vulnerability.  When hydrogen demand grows in emerging sectors, it is frequently drawing supply from a production ecosystem designed decades earlier for entirely different industrial priorities.  When refinery demand shifts or production tightens, the ripple effects reach far beyond gasoline and diesel production.

Understanding who depends on that system is critical to understanding the fragility of the hydrogen economy.

Where Hydrogen Actually Comes From

Globally, hydrogen production is dominated by two industrial uses. Oil refining consumes hydrogen for hydrocracking and desulfurization processes that convert heavy crude oil into gasoline, diesel, and jet fuel.  Fertilizer production consumes hydrogen as a feedstock for ammonia synthesis, which is essential for modern agriculture.  Methanol production is the third largest hydrogen consumer. The first step of most plastics is methanol production.  

Together, these three sectors consume the vast majority of hydrogen production. Estimates from international energy agencies consistently show that roughly two thirds of hydrogen is used by refineries, while most of the remainder supports ammonia for fertilizer and methanol production.  Keep in mind that refineries drive the demand and as a result petrochemical and fertilizer plants are located nearby.

Everything else shares what is left, and the problems emerge when they are not located nearby.

Semiconductor manufacturing, chemical production, glass fabrication, steel processing, electronics manufacturing, aerospace, power plants, and hydrogen mobility often depend on merchant hydrogen supplied through industrial gas producers or distributors.

This merchant hydrogen frequently originates from production assets built to serve refineries or ammonia plants.

The hydrogen economy therefore rests on a foundation that few outside the industrial gas sector fully recognize.

Hydrogen production infrastructure is concentrated around large petrochemical complexes where demand is stable and continuous.  These facilities are optimized for scale, efficiency, and predictable industrial consumption.  They are not optimized for distributed demand across dozens of smaller industries and regional customers.

This structural concentration shapes the entire supply chain.

Liquid Hydrogen and the Merchant Supply Network

Once hydrogen is produced as a gas it must be compressed or liquefied before distribution.   Liquefaction allows hydrogen to be transported efficiently in bulk tanker trucks to customers that cannot justify building their own production systems.

Liquid hydrogen distribution networks supply a wide range of industries that require reliable hydrogen but do not operate large, centralized hydrogen production plants themselves.

These industries include electronics manufacturing, aerospace programs, advanced materials production, food processing, drug processing, metals manufacturing, power production, other manufacturing and scientific research at universities.

Industrial gas companies operate liquefaction plants that convert gaseous hydrogen into cryogenic liquid form (-451 degrees F).  Tanker fleets then deliver hydrogen across regional supply networks to customers ranging from semiconductor fabs to research laboratories.

These customers rarely produce hydrogen themselves. Instead, they depend on the reliability of the merchant hydrogen system.

When supply disruptions occur upstream, those effects propagate quickly.

Semiconductor Manufacturing and Ultra High Purity Hydrogen

Semiconductor fabrication represents one of the most sensitive hydrogen dependent industries in the world.  Hydrogen is used in wafer annealing, epitaxial growth, chemical vapor deposition, extreme ultraviolet lithography and several cleaning processes essential to chip manufacturing.

The semiconductor industry requires extremely high purity hydrogen.  Contamination can destroy entire batches of wafers, resulting in millions of dollars in losses.  As a result, semiconductor facilities often rely on specialized industrial gas distributors that deliver hydrogen produced and purified through large scale supply networks.

Most semiconductor manufacturers do not operate their own hydrogen plants.  Instead, they rely on regional hydrogen supply infrastructure that ultimately traces back to merchant hydrogen production facilities.

As semiconductor manufacturing expands globally, particularly with the construction of new fabrication plants in the United States and Europe, hydrogen demand from this sector will increase significantly.  Also, the latest high-performance chips require finer (thinner) circuits, and the lithography process has shifted to using high purity hydrogen to etch those circuits.  The challenge is that the underlying hydrogen supply chain was never designed specifically to support these distributed technology clusters.

Chemical Manufacturing and Industrial Feedstocks

Hydrogen plays a central role in chemical manufacturing. It is used in methanol production, hydrogen peroxide synthesis, plastics, foams and pharmaceutical manufacturing, and a variety of specialty chemical reactions.

Large chemical complexes sometimes produce hydrogen internally, but many mid-sized producers rely on delivered hydrogen supplied through industrial gas firms.  These deliveries frequently originate from liquefaction plants linked to the broader refinery-based hydrogen ecosystem.

Because chemical production often occurs in regional clusters rather than at massive refinery complexes, distributed hydrogen supply is essential.  When merchant hydrogen supply becomes volatile due to refinery demand fluctuations or production constraints, pricing volatility, as well as availability occurs so chemical producers feel the impact quickly.

The dependence is structural rather than incidental.

Food Processing and Hydrogenation

Hydrogen is also an important industrial input in food processing.  Hydrogenation processes convert vegetable oils into margarine, shortening, and other food products with specific chemical characteristics.

Although food processors are not commonly associated with the hydrogen economy, many facilities rely on hydrogen deliveries from industrial gas suppliers to operate these processes.

As with other industries, these facilities often depend on merchant hydrogen supplied through liquefaction networks tied to large, centralized hydrogen production plants. The hydrogen economy therefore extends into industries far removed from energy production.

Steel and Metal Processing

Hydrogen is widely used in metallurgy and materials processing.  It provides reducing atmospheres for heat treatment and annealing, helps prevent oxidation during manufacturing processes, and is increasingly being explored as a reducing agent in low carbon steel production.  While the production of steel and aluminum ingots require oxygen, rolling it and bending it requires hydrogen to anneal it.

The emerging hydrogen based direct reduced iron process has attracted global attention as a pathway to decarbonize steel manufacturing.  However, large scale hydrogen supply remains the limiting factor.

Even before these new technologies scale, many metallurgical operations rely on hydrogen delivered through the same merchant hydrogen system that supports other industrial users.

As hydrogen demand grows for steel decarbonization, the strain on existing supply infrastructure will become more pronounced.

Aerospace and Rocket Launch Systems

One of the most visible uses of hydrogen occurs in the aerospace industry.  Liquid hydrogen is used as rocket fuel because of its high energy content and clean combustion properties.

Liquid H2 is used in rocket fuel

Space launch systems operated by NASA, SpaceX, United Launch Alliance, and other aerospace organizations rely on liquid hydrogen deliveries from specialized industrial gas suppliers.

Historically, disruptions in hydrogen supply have delayed launches and forced scheduling adjustments. Rocket programs therefore depend on reliable liquid hydrogen supply chains that originate from the same merchant hydrogen infrastructure supporting other industries.

The aerospace sector illustrates how critical hydrogen reliability can be when supply disruptions occur.

Hydrogen Mobility and Material Handling

Hydrogen mobility has also emerged as a growing consumer of hydrogen.  Fuel cell forklifts deployed by companies such as Amazon and Walmart rely on consistent hydrogen deliveries to operate efficiently and cleanly as their exhaust is water vapor

These deployments were among the first large scale attempts to integrate hydrogen into logistics operations.  The forklifts themselves performed well, offering fast refueling and consistent power output compared to battery powered alternatives.

However, the hydrogen used by these systems often originated from the same refinery linked merchant hydrogen network supplying other industries.  When hydrogen supply tightened and prices increased, companies responsible for guaranteeing hydrogen supply were forced to purchase hydrogen at elevated market prices.

The forklifts did not fail technologically.  The underlying supply system exposed its limitations.

The Structural Risk in the Hydrogen Economy

Taken together, these industries reveal an uncomfortable reality.  Much of the hydrogen economy depends on production capacity that was never designed to serve it.

Hydrogen supply is concentrated around refineries and ammonia plants used as a gas and delivered cleanly and efficiently via pipeline.  Merchant hydrogen markets distribute excess production in a liquid form through liquefaction and transport networks.

When refinery operations change or supply tightens, hydrogen availability for secondary users becomes uncertain. Industries that rely on delivered hydrogen are effectively downstream customers of a supply chain controlled by other sectors.

This dependency is rarely discussed in public conversations about hydrogen expansion.

Yet it shapes the entire market.

What Happens When Supply Tightens

As energy markets evolve, refinery activity may change due to increased needs in electrification, fuel demand shifts, or environmental regulation.  When refinery hydrogen production declines or shifts geographically, merchant hydrogen supply networks must adapt.

Industries that depend on liquid hydrogen deliveries will face rising costs and potential supply constraints unless new production capacity is developed specifically to serve distributed demand.

This challenge will become more pronounced as hydrogen demand expands for mobility, steel production, semiconductor manufacturing, and energy storage.

The hydrogen economy cannot continue relying on surplus production from industries with completely different priorities.

A System Built for Yesterday

The current hydrogen supply chain reflects the industrial priorities of the past century. Oil refining, petrochemicals, plastics and fertilizer production shaped its structure. Liquefaction plants and merchant hydrogen markets evolved to distribute surplus production to other industries.  Liquefaction and transport are both energy intensive and capital intensive, and ironically only the aerospace industry requires hydrogen in a liquid form.  Nearly every other industrial user must warm the liquid hydrogen back into gas before it can be used in their processes, which also results in boiloff losses during storage and handling.

For decades this system functioned because hydrogen demand outside refineries, petrochemicals and fertilizer production was relatively small. Semiconductor manufacturers, metals processors, chemical plants, food producers, aerospace programs and research laboratories could rely on merchant hydrogen supply networks that quietly redistributed excess production from these large industrial hubs.

But that balance is beginning to change.

Hydrogen demand is expanding rapidly across industries that were never part of the original supply equation. Semiconductor fabrication is scaling globally. Steel producers are exploring hydrogen-based reduction processes. Distributed power systems and energy storage applications are emerging. Hydrogen mobility continues to develop across material handling, heavy transportation and other industrial equipment.

All of these sectors are drawing from a hydrogen system that was never designed to support them.

The result is an increasingly fragile supply chain where a shift in refinery operations, a regional production disruption, or a tightening of merchant hydrogen capacity can ripple across industries that depend on hydrogen for completely different purposes.

In many ways, the hydrogen economy already exists.  It powers critical manufacturing processes, supports advanced technologies, and enables industries that modern life depends on.  Yet the infrastructure that supports it remains tied to an industrial system built for yesterday's priorities.

If hydrogen is truly expected to play a central role in the future energy and manufacturing economy, its supply chain will need to evolve from one built around refinery excess capacity to one designed for distributed industrial demand.

Because the question is no longer whether the world will need more hydrogen.

The question is whether the hydrogen supply system will evolve quickly enough to support the industries that already depend on it.
