Bulk industrial gases

Why the concentration exists

Bulk industrial gases are atmospheric gases delivered in large volumes for continuous industrial production. They are produced primarily through cryogenic air separation, which uses fractional distillation of liquefied air. Cryogenic distillation is the current mainstream technology for bulk supply. The three atmospheric gases exist in air at fixed proportions of 20.95% oxygen, 78.08% nitrogen, and 0.93% argon. Bulk supply is defined as gases with purity of 99.99% or less, distinguishing them from higher-purity electronic grades.[1][21]

Supply is concentrated because bulk gas production requires large air separation units connected to extensive pipeline networks. Air Liquide's pipeline network extends over 9,700 km for transporting bulk industrial gases. In the United States, Air Liquide owns and operates more than 2,000 miles of industrial gas pipelines along the Gulf Coast. These fixed assets lock customers into long-term supply contracts because the alternative of building competing infrastructure is uneconomic.[11][15]

Few large producers contribute to 50% of total manufactured oxygen in the world. The supply chain requires sophisticated system engineering covering production, purification, and transportation. Each step has its own technical difficulties and strict standards. Bulk gas installations provide scalability through large-capacity storage systems that can handle variations in usage patterns. Manufacturing operations require gas supply systems that scale with production demands while maintaining unwavering reliability.[23][1][5]

What the evidence shows

Who supplies it

Major players including Linde, Air Liquide, and Air Products control approximately 75-80% of the global industrial gases market. Prominent companies in the industrial gas market include The Linde Group, Air Liquide, and Air Products and Chemicals. Global industrial gases market size reached USD 109.4 Billion in 2024. Atmospheric gases accounted for the largest market share of 48.4% among product types in 2024.[27][19][28]

Air Liquide's Large Industries business line operates more than 300 large air separation units for bulk industrial gas production. In 2025, the Large Industries business line generated 7,110 million euros in revenue, representing 26.4% of Air Liquide's group revenue. Air Liquide is present in 75 countries with approximately 66,400 employees and serves more than 3.8 million customers and patients. Airgas, an Air Liquide company, has 18,000+ bulk tanks installed, 31+ Air Separation Units, and 15+ CO2 plants.[11][14][13]

Messer is the largest privately held industrial gas business in the world, with Americas sales accounting for more than 50% of worldwide sales of over $5 billion USD. POSCO operates 20 air separation units, the largest fleet in Korea. Nippon Sanso Matheson supplies bulk oxygen for electronics and semiconductors with purity up to 99.9999%. Leading companies in the bulk specialty gas system market also include Taiyo Nippon Sanso, Messer Group, Swagelok, Parker Hannifin, and others.[17][9][22][26]

What it depends on, and what depends on it

Industrial gases are used in a wide range of industries, including manufacturing, healthcare, food and beverage, electronics, and energy. Several industries, including metallurgy, petrochemicals, electronics, healthcare, and food processing, are driving up demand for these gases. POSCO supplies oxygen, nitrogen, and argon as bulk industrial gases. Nippon Sanso Matheson supplies bulk oxygen for laboratories with purity up to 99.999%.[2][8][9][22]

INOX Air Products signed a 15-year contract to supply 2,400 Nm³/hr of ultra-high purity nitrogen to Insolation Green Energy's 4.5 GW solar cell plant. Messer is a trusted medical bulk oxygen supplier to over 1,000 hospitals nationwide, supported by more than 30 production facilities. Air Liquide supplies primarily nitrogen, oxygen, and hydrogen to more than 350 pipeline customers in the U.S. Cryogenic storage tanks for bulk oxygen range in size from 500 to 420,000 gallons.[25][16][15][24]

Where it sits in the stack

What would break it

In August 2025, a decree signed by Vladimir Putin placed Air Liquide's subsidiaries under temporary management of the Russian company M-Logistika. This represents a sudden loss of operational control in a major market. To compensate for the loss of Russian natural gas supplies, Germany and the EU are importing more liquefied natural gas. Such geopolitical shifts can disrupt established supply chains and force rapid restructuring.[18][6]

Air Liquide and Siemens Energy inaugurated the world's first PEM gigawatt electrolyzer factory in Berlin in November 2023, with a production capacity of three gigawatts by 2025. This represents a shift toward green hydrogen production at industrial scale. Companies like Air Liquide will be able to leverage existing infrastructure and scale to further press their advantages over competitors. The coming years will present unprecedented possibilities in green hydrogen, high-purity gases, and bio-based solutions.[10][4][7]

UIG provides onsite generators as small as 20,000 standard cubic feet an hour through thousands of tons per day. I-MAXIMUM offers alternative gas supply systems based on mixing Propane and Air to produce synthetic natural gas. Microbulk offers significant cost savings compared to cylinders and uses less floor space. These alternatives could erode demand for traditional bulk supply in certain applications.[20][7][3]

What to watch

The bulk specialty gas system market is expected to see widespread adoption of fully automated, AI-optimized gas management platforms in the 2026-2030 timeframe. Air Liquide and Siemens Energy inaugurated the world's first PEM gigawatt electrolyzer factory in Berlin in November 2023, with a production capacity of three gigawatts by 2025. Air Liquide's Integrated Bulk Operations program, which connects assets in the liquid gas supply chain, was launched in 2017.[26][10][12]

On August 22, 2025, Air Liquide agreed to buy South Korea's DIG Airgas for 2.85 billion euros ($3.31 billion). Air Liquide announced the acquisition of DIG Airgas in 2025, becoming the industrial gas leader in South Korea. In September 2025, POSCO began supplying industrial gases to battery manufacturers at a facility in Pohang's Yeongil Bay Industrial Complex.[18][10][9]
