Air Liquide sells industrial gases like oxygen and nitrogen, along with the equipment and services that big factories and hospitals need to use them.
Air Liquide is one of the world's biggest suppliers of industrial gases — the invisible stuff that keeps modern industry running. Hospitals need oxygen for patients. Steel mills need oxygen to make steel. Food companies need nitrogen to keep packaged snacks fresh. Electronics factories need ultra-pure gases to make computer chips. Air Liquide produces these gases at large plants and then pipes or trucks them to thousands of customers who can't practically make them on their own.
The clever part is how the business locks in. Gases are cheap but tricky to transport, so Air Liquide often builds an on-site plant right next to a customer's factory and runs it for them under a long-term contract — sometimes twenty years or more. That means steady, recurring revenue and customers who rarely switch. The company also sells the equipment that uses the gases, like welding gear and medical breathing devices, and increasingly it sells the expertise too, designing the systems that let a factory use gases efficiently. Air Liquide has also pushed into what it calls "electronics" — supplying the specialized gases for chipmaking — and into health, where it serves hospitals and home-care patients who need oxygen and other therapies at home. It's a French company, founded way back in 1902 (the name literally means "liquid air," because its founders figured out how to turn air into a liquid and separate out the oxygen). It now operates in dozens of countries, making it a quiet but essential pillar of global industry.
The business is steady and cash-generative, which is why Air Liquide has become a dividend favorite in Europe. Its main vulnerability is energy: making industrial gases consumes a lot of electricity, so rising power prices squeeze margins. It also faces competition from rivals like Linde and Air Products. Looking ahead, the company is betting big on hydrogen as a cleaner fuel — a potentially huge new market, but one still in its early, uncertain stages.
