Science and digital, at the heart of all our innovations
A unique scientific expertise
Thanks to its strong expertise in Essential Small Molecules and its knowledge of data science, R&D has a wide range of skills in materials science, process engineering, life science, chemistry, combustion, cryogenics and analytical science that enable Air Liquide to continuously develop new applications for its molecules. With its scientific and industrial partners, R&D is actively working to deepen its knowledge of Essential Small Molecules in order to explore new horizons and thus provide solutions to future challenges in industry and health.
Our 18 Essential Small Molecules are: oxygen (O2), nitrogen (N2), hydrogen (H2), carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), argon (Ar), xenon (Xe), krypton (Kr), neon (Ne), helium (He), nitric oxide (NO), nitrous oxide (N2O), acetylene (C2H2), ozone (O3), water (H2O) and silane (SiH4).

Innovation with ecosystems
Our innovation is part of an open, global ecosystem. It is supported by our Innovation Campuses in Europe, the United States and Asia, the Campus Technologies Grenoble in France, and the Digital Factory.
Our innovation teams bring together profiles of different nationalities and skills: scientific and technical profiles in Research & Development, developers, engineers, network architects, designers, data scientists within Digital & IT (including Alizent), technical and commercial profiles for the Global Markets & Technologies activity, or for ACCELAIR and ALIAD.
Accelerating innovation with start-ups
Air Liquide works with around a hundred start-ups to accelerate innovation and integrate new products, technologies and solutions into the Group's offerings.
With ALIAD, the Group's venture capital investor, Air Liquide supports innovative technological start-ups to help them grow, with the objective of helping them industrialize their products and access different markets. This support takes the form of minority stakes in the start-up's capital.
ACCELAIR, Air Liquide's deep tech start-up accelerator, hosted on the Innovation Paris Campus, offers selected start-ups access to experimentation spaces (laboratories, test platforms) and a support programme run by Air Liquide experts to accelerate the process of bringing their offer to market.
