Turning vision into industrial reality through innovation

Innovation at Air Liquide is measured by the impact it delivers. We start off with an idea, which we shape into a concrete, useful solution that we then deploy at scale with and for our customers.

Our committed teams—from our R&D units to those working in our plants—drive this approach, built around a targeted and dynamic innovation portfolio. We also leverage artificial intelligence (AI) and data, which support us in consolidating our knowledge, enhancing our expertise, and shortening the path from exploration to industrialization.

At Air Liquide, innovation is not just a process: it is our very culture, expressed with a pioneering spirit that is both bold and pragmatic. Innovation at Air Liquide is firmly focused on delivering the impact needed to advance our technologies and operations, while preparing the Group’s future.

From our laboratories to our industrial units, innovation transforms breakthrough ideas into concrete, deployable solutions that serve our customers, patients and society as a whole. This dynamic relies on a structured approach: develop a portfolio of targeted projects, accelerate scale-up, and drive the transformations required to remain a technological leader in a rapidly changing world.

Two priorities stand out as factors that can best reshape our trajectory. First, there is the energy transition, which calls for ever more efficient, reliable and resource-conscious solutions. Second, the semiconductor industry, whose development—led by the rise of artificial intelligence and its infrastructures—is redefining performance standards.

Beyond sector dynamics, AI is also emerging as a driver of structural transformation. Combined with our teams’ expertise, it enables us to explore faster, make better decisions, and deploy more effectively. By leveraging it today in support of our key priorities, we are strengthening our capacity to deliver high impact solutions.

  • Ammonia cracking: a cornerstone of a global low-carbon hydrogen value chain
    November 2025 marked the commissioning of the world’s first industrial-scale pilot unit producing hydrogen (H₂) through ammonia (NH₃) cracking. Located in the port of Antwerp-Bruges, Belgium, the plant—capable of converting 30 tons of ammonia into hydrogen per day—removes a major barrier to the development of a truly global hydrogen economy.
