The Industrial Gas Industry's Stable Structure and What Is Disrupting It
The industrial gas industry — producing and distributing oxygen, nitrogen, argon, carbon dioxide, hydrogen, helium, and specialty gases for industrial, medical, and electronics applications — has been one of the most stable and consistently profitable sectors of the global chemicals industry for the better part of a century. The sector's stability has rested on a set of structural characteristics that are unusual in the chemicals industry: long-term take-or-pay supply contracts that underpin plant economics with contracted revenue; on-site or pipeline-supplied customer relationships that create switching barriers through the capital cost and operational disruption of switching gas supplier; the oligopolistic market structure in most national and regional markets, where the economies of production scale and distribution network density limit viable competition to a small number of large operators; and the essential-good nature of the industrial gases that most industrial production processes depend on, creating demand that is insensitive to economic cycles in its baseline and correlated with industrial production in its growth rate. Air Liquide, Linde, Air Products, and Messer — the four dominant global industrial gas companies — have built businesses of extraordinary stability and profitability on these structural foundations.
The green energy transition is disrupting this stable structure in ways that are simultaneously creating enormous opportunity for the industrial gas industry and challenging the business model foundations that have sustained its stability. The disruption operates through several channels simultaneously. Green hydrogen production — the electrolysis of water to produce hydrogen using renewable electricity, without the carbon emissions of the steam methane reforming that produces the vast majority of today's hydrogen supply — is creating demand for a new category of hydrogen production and distribution infrastructure that differs fundamentally from the grey hydrogen production plants that the industrial gas companies have operated for decades. Carbon capture, utilisation, and storage — which uses CO2 as a feedstock for industrial processes or sequesters it in geological formations — is creating demand for CO2 capture, compression, and transport infrastructure that the industrial gas companies are well positioned to supply. And the energy transition in the industries that the industrial gas companies serve — steel, chemicals, refining, cement — is changing the production processes of those industries in ways that alter their industrial gas demand profiles in both volume and composition.
Hydrogen: The Market-Defining Opportunity
Hydrogen is the industrial gas market's defining opportunity in the green energy transition era, because the anticipated growth of green hydrogen production — from a current volume of less than 1 million tonnes per year globally to the hundreds of millions of tonnes per year projected in the most ambitious decarbonisation scenarios — would dwarf the current scale of the hydrogen market and create a transformation in the business that manages its production, storage, and distribution. The industrial gas companies are uniquely positioned for this opportunity: they have decades of experience producing, purifying, compressing, storing, and distributing hydrogen; they have the customer relationships in the steel, chemical, and refinery industries that represent the primary near-term green hydrogen demand; and they have the engineering, project development, and supply chain capabilities required to build the large-scale electrolysis plants, storage infrastructure, and distribution systems that green hydrogen supply chains require.
Air Products has made the most aggressive commitment to the green hydrogen opportunity, with multi-billion dollar investments in the NEOM green hydrogen project in Saudi Arabia — one of the largest green hydrogen projects in the world — and in a green hydrogen production and distribution network in the United States and Europe. Air Liquide, Linde, and a growing number of regional industrial gas companies are pursuing green hydrogen opportunities across multiple geographies with investment programmes that reflect the strategic importance the sector assigns to hydrogen in the energy transition. The competitive dynamic in green hydrogen development is distinct from the oligopolistic stability of the conventional industrial gas market: new entrants including electrolyser manufacturers, energy companies, and utility companies are pursuing hydrogen supply positions, and the technology landscape of electrolysis — which draws on electrochemical engineering rather than the cryogenic distillation expertise of conventional industrial gas production — opens the market to competitors whose capabilities are different from those of the established industrial gas incumbents.
Carbon Dioxide: From Commodity to Climate Tool
Carbon dioxide has historically been a commodity industrial gas — a by-product of combustion, fermentation, and chemical production processes whose commercial value as an industrial gas was modest and whose market dynamics were driven by local production and distribution economics. The green energy transition is transforming CO2's status from an industrial by-product to a central element of the carbon management strategies that industries, governments, and financial markets are building to address climate change. Carbon capture — the separation and compression of CO2 from industrial and power generation flue gases for transport to geological storage or industrial utilisation — is creating demand for gas processing infrastructure at industrial facilities whose CO2 emissions must be managed under tightening regulatory frameworks. CO2 utilisation — the use of captured CO2 as a feedstock for e-fuels, enhanced oil recovery, greenhouse horticulture, and food and beverage carbonation — is creating a demand-side market for CO2 that adds commercial value to carbon capture beyond the avoidance of carbon pricing costs alone.
The industrial gas companies' position in the emerging CO2 value chain rests on their expertise in gas capture, compression, purification, and transport — skills directly transferable from their oxygen and nitrogen production operations to CO2 management. Air Liquide has been particularly active in developing CO2 capture and transport infrastructure in industrial clusters in Europe, and Linde's engineering and construction capabilities position it as a builder and operator of carbon capture facilities for third-party industrial clients. The development of CO2 transport networks — pipeline infrastructure connecting industrial CO2 sources to geological storage sites or utilisation facilities — creates a new infrastructure category that resembles the liquid and pipeline gas distribution networks that the industrial gas companies have historically operated, and in which their capital allocation and project development capabilities are directly applicable.
Electronics and Healthcare Gases: The Stable High-Margin Core
While the green energy transition is creating the structural disruption that will define the industrial gas market's long-term evolution, the electronics and healthcare gas segments are providing the stable, high-margin revenue foundation that funds the investment in green energy transition opportunities. Specialty gases for semiconductor manufacturing — the ultra-high purity process gases, noble gases, and specialty chemical precursors that semiconductor fabrication requires — are growing with the semiconductor industry itself, which as described elsewhere in this publication is growing at rates above those of the broader economy driven by AI infrastructure investment and the digitalisation of industrial production. Medical gases — oxygen and nitrous oxide for anaesthesia and critical care, medical air, and the specialty gases used in medical devices and pharmaceutical manufacturing — have stable demand profiles that are insensitive to economic cycles and provide predictable revenue that offsets the capital intensity of the green energy transition investments the industrial gas companies are making. The combination of stable, high-margin core revenue in electronics and healthcare, growth in green hydrogen and carbon management, and the sustained demand from traditional industrial customers creates a business mix for the leading industrial gas companies that is more diversified and, in the long term, more resilient than the conventional industrial gas market structure alone would provide.
