Overview

Air Liquide is a Paris-based industrial group whose principal business is the production, distribution and application of gases used by industry, healthcare, research and emerging energy systems. Founded in 1902 by Georges Claude and Paul Delorme, the company developed from early work on air liquefaction and industrial oxygen into one of the world's largest industrial-gas suppliers. Its portfolio includes oxygen, nitrogen, hydrogen, argon, carbon dioxide, helium and other specialty gases, together with gas-management systems, process technologies, equipment and technical services. The company serves a broad customer base rather than relying on a single end market. Large industrial customers such as steelmakers, chemical producers, refiners and energy companies are commonly supplied through dedicated production plants and pipeline networks. Smaller and medium-sized businesses can obtain cylinder and bulk products through the industrial-merchant channel. Air Liquide also supplies hospitals, clinics, home-care patients and laboratories with medical gases and associated services. Electronics customers use high-purity gases and process materials in the manufacture of semiconductors, displays and photovoltaic products. Other applications include food preservation, metal fabrication, aerospace, automotive production, pharmaceuticals, water treatment and scientific research. Air Liquide's historical growth has combined internal engineering capability, geographic expansion and acquisitions. The group expanded outside France during the first half of the twentieth century, entered large-industry gas supply in the 1950s and developed industrial pipeline systems serving major manufacturing regions. Its engineering activities design and build air-separation units, hydrogen plants and other gas-production infrastructure for both group operations and external customers. The company also accumulated activities in welding, diving and technical equipment, although the scope and organization of these businesses have changed over time. A major strategic turning point came with the acquisition of the United States-based Airgas. Announced in 2015 and completed in 2016 after regulatory review and required asset divestitures, the transaction substantially expanded Air Liquide's American distribution network and strengthened its packaged-gas, healthcare and specialty-gas businesses. The consolidation of the industrial-gas sector following the 2018 merger of Linde and Praxair left Air Liquide as one of the two leading global competitors, alongside Linde, with Air Products as another major international rival. In the twenty-first century, Air Liquide has increasingly positioned hydrogen, carbon-management solutions, low-carbon production, advanced materials and digital operations as growth areas alongside its established gas businesses. Hydrogen activities cover production, liquefaction, distribution, mobility infrastructure and industrial use. The company has also pursued partnerships and projects connected with heavy-duty transport, electronics and decarbonization. Its activities are generally organized around gas and services, engineering and construction, and global markets and technologies, with regional execution across a large international network. The company remains headquartered in Paris and operates across Europe, the Americas, Asia-Pacific, the Middle East and Africa. François Jackow became chief executive officer in 2022, while Benoît Potier serves as chairman of the board. Air Liquide is a publicly traded company on Euronext Paris. Its competitive position rests on long-term customer contracts, capital-intensive production and distribution assets, process engineering expertise, safety and reliability requirements, and the ability to integrate gas supply with customers' industrial and healthcare workflows.

History

Air Liquide was established in France in 1902 by Georges Claude and Paul Delorme around the industrial use of air liquefaction and oxygen production. The founding technology enabled the company to supply gases at a time when oxygen was becoming important to metallurgy, welding, chemical production and medical treatment. The business gradually developed from a French specialist into an international industrial group, combining gas production with engineering, plant construction and distribution. During the 1930s and 1940s, Air Liquide expanded its international footprint, including through operations in Argentina. The postwar period brought further organizational development and geographic growth. In 1957, the group began supplying large industrial customers through dedicated networks and pipeline systems. This model connected gas-production facilities directly to major industrial consumers and became a central feature of the company's large-industries business. In 1962, Air Liquide entered the space sector, extending its expertise in cryogenic gases, propulsion-related systems and specialized engineering. From the 1960s through the 1990s, the company broadened its activities in healthcare, electronics, research, welding and other technical markets. It continued to invest in air-separation plants, gas logistics and application technologies. The engineering and construction business allowed Air Liquide to design and build production facilities for its own network and, in some cases, for third parties. The group also developed merchant-gas operations, supplying cylinders and bulk products to customers whose demand did not justify a dedicated pipeline installation. The company entered the twenty-first century as a diversified industrial-gas supplier serving large industry, industrial merchants, healthcare and electronics. Its international model combined local distribution and customer service with globally transferable process technology. Medical gases became an important area, covering hospitals, clinics and home-care patients, while high-purity gases supported semiconductor, flat-panel and photovoltaic manufacturing. A defining corporate event was the acquisition of Airgas in the United States. Air Liquide announced the transaction in November 2015 and completed it in May 2016 after obtaining approval from the U.S. Federal Trade Commission. The parties were required to divest specified production and distribution assets, including facilities associated with bulk oxygen, nitrogen, argon, carbon dioxide, dry ice, nitrous oxide and packaged welding gases. Airgas became a wholly owned subsidiary, giving Air Liquide a substantially larger U.S. operating platform. The competitive structure of the sector changed again in 2018 when Linde and Praxair combined. The transaction created a larger rival and placed Air Liquide among the leading global industrial-gas companies. Air Liquide has since pursued growth through its existing gas-and-services operations and through selected investments in hydrogen, low-carbon production, carbon-management technologies, digital tools, advanced materials and other markets requiring specialized engineering. Leadership changed in 2022, when François Jackow became chief executive officer and Benoît Potier became chairman of the board after serving as chief executive for many years. Under the current structure, Air Liquide operates through regional gas-and-services businesses supported by engineering and construction capabilities and a global markets and technologies organization. Its customer base spans metals, chemicals, refining, energy, healthcare, food, pharmaceuticals, automotive, aerospace, electronics and research. Hydrogen has become a prominent strategic theme. Air Liquide participates in hydrogen production and supply for industrial users and has explored mobility applications, including partnerships intended to support refueling networks for heavy-duty vehicles. The group continues to rely on the characteristics that have historically defined industrial gases: high safety and reliability standards, long-term customer relationships, extensive physical infrastructure, process know-how and the ability to tailor supply arrangements to different scales of demand.
