Air Liquide organizes its activities principally into a Gas & Services segment (Large Industries, Industrial Merchant, Healthcare, Electronics), plus Engineering & Technologies and Global Markets & Technologies; each segment delivers production, distribution, equipment and specialist services for industrial, medical and high-tech customers worldwide and together they accounted for roughly 97% of Group revenue in 2025.
What each main segment delivers
Gas & Services supplies bulk and packaged gases (oxygen, nitrogen, hydrogen, rare gases), on-site production, pipelines and aftermarket services to heavy industry, mid-sized industrial customers and hospitals; this segment remains the Group's largest revenue source.
Large Industries builds and operates dedicated production plants and pipeline networks under long-term contracts (typically 15-20 years), delivering continuous high-volume gases to steel, chemicals, refining and energy customers and supporting other Group activities with bulk supply.
Industrial Merchant serves about 2 million customers with cylinder, liquid and small-bulk deliveries, rental equipment, and application services (welding, food processing, metal fabrication), often through dense local distribution networks and acquisitions of regional players.
Healthcare provides medical gases, home-care respiratory services, hospital oxygen systems, consumables and digital patient support; the activity includes medical device services and supply of specialty ingredients used in pharmaceuticals and vaccines.
Electronics offers ultra-high-purity gases, specialty molecules, carrier gases, advanced materials and on-site gas generation for semiconductor fabs, flat-panel and photovoltaic manufacturers, where product purity and rapid responsiveness are critical.
Engineering & Technologies delivers engineering, construction, process technologies and turn-key plants for industrial gas production (air separation, hydrogen units, cryogenics), supporting internal projects and third-party clients worldwide.
Global Markets & Technologies (also described as Global Markets or Technologies) focuses on innovation, specialty ingredients, hydrogen value-chain projects (production, storage, distribution), decarbonization solutions and industrial R&D partnerships.
How the segments work together
- Shared production: Large Industries plants produce bulk gases that feed Industrial Merchant and Healthcare deliveries within the same industrial basins.
- Engineering support: Engineering & Technologies designs and builds plants used across the Group, enabling faster deployment of on-site units.
- Cross-selling: Electronics and Global Markets leverage purity technologies and specialty molecules developed in R&D to create high-margin products.
- Hydrogen integration: hydrogen production and distribution is coordinated across segments to serve mobility, industry and energy-transition projects.
Key statistics and historical context
Founding and scale: Air Liquide was founded in 1902 and by 2025 reported presence in roughly 59-73 countries with approximately 65,000-66,500 employees and more than 4 million customers and patients served globally.
Revenues and segment weight: In the 2025 reporting cycle, the company cited that Gas & Services activities accounted for about 97% of Group revenue, with consolidated revenue figures reported in recent filings around $29.3 billion for 2024 (reporting conventions vary by currency and year).
R&D and patents: The Group filed hundreds of patents in recent years (350+ reported in 2022) and invested tens to low hundreds of millions annually on innovation for energy transition and specialty materials; management announced multi-billion ambitions for low-carbon hydrogen through 2035 (an illustrative target of roughly $8.6 billion of planned investment across the value chain).
Hydrogen footprint: Air Liquide's hydrogen activities historically expanded from the 1990s and by recent accounts included large-scale production, pipeline networks and storage solutions; hydrogen sales and projects are highlighted as strategic for mobility and industrial decarbonization.
Service and product breakdown (illustrative table)
| Segment | Main products & services | Primary customers | Contract type / term |
|---|---|---|---|
| Large Industries | Bulk O2, N2, H2; pipelines; on-site plants | Steel, chemicals, refineries, energy | Long-term (15-20 years), JV or supply agreement |
| Industrial Merchant | Cylinders, liquid deliveries, rental equipment, services | SMEs, fabricators, food processors | Spot and recurring deliveries, local contracts |
| Healthcare | Medical gases, home oxygen therapy, hospital systems | Hospitals, clinics, patients at home | Service contracts, reimbursement-based arrangements |
| Electronics | Ultra-pure gases, specialty molecules, on-site gas systems | Semiconductor fabs, panel manufacturers | Short lead-time supply, long-term quality agreements |
| Engineering & Technologies | Plant engineering, construction, licensing | Group projects, third-party industrial clients | Project-based, EPC contracts |
| Global Markets & Tech | Specialties, hydrogen solutions, R&D collaborations | Pharma, energy, mobility projects | Partnerships, commercialization agreements |
Revenue & regional structure (compact numbered summary)
- Gas & Services accounted for the vast majority of revenue in recent annual reports (about 97% in 2025 reporting summaries).
- Geographical split typically shows material sales across EMEA, Americas and Asia-Pacific, with the United States and Europe as key markets by revenue.
- Capital intensity is high: Large Industries projects require multi-year CAPEX with long payback but stable recurring cash flows via long contracts.
Selected historical milestones
1902 founding: Air Liquide was established in 1902 and gradually expanded from oxygen/nitrogen supply into hydrogen and specialty gases over the 20th century.
1990s hydrogen growth: The company began systematically developing hydrogen value chains from the mid-1990s, later adding pipeline and storage networks to serve refining and emerging mobility markets.
2020s energy transition: In the 2020-2025 period, management prioritized low-carbon hydrogen and decarbonization services, committing substantial R&D and partnerships to scale up electrolytic and low-carbon production.
Operational examples
On-site production: For a large steel mill, Air Liquide may install an air-separation or hydrogen unit onsite under a 15-20 year contract providing guaranteed availability and joint plant operation responsibilities.
Home healthcare: A patient with chronic respiratory failure can receive oxygen concentrators and follow-up digital monitoring services under local home-care programs contracted through health providers.
Quote - "Our Gas & Services activities are the structural core of Air Liquide and account for nearly all our revenues," a recent corporate report noted in the 2025 integrated disclosure.
Common questions
How customers choose services
Large industrials select on reliability, cost per ton and integration with processes; they prioritize long-term partnerships and pipeline access.
SMEs and local customers choose based on delivery frequency, local service density and rental equipment options provided by the Industrial Merchant network.
Healthcare providers select on regulatory compliance, supply redundancy and patient service capabilities for home oxygen, while pharmaceutical clients require traceability and specialty-ingredient quality.
Practical metrics to watch
Revenue share by segment (watch Gas & Services percentage each year), capital expenditure on Large Industries projects, number of on-site plants installed, hydrogen tons sold annually, and R&D/patent filings are useful KPIs for analysts tracking the Group.
