While serving a vanguard Navy, Air Liquide is also innovating

Shipbuilding has long been regarded as an indicator of a country's industrial capacity. It is a great source of innovations, including ships that use renewable energy as a means of propulsion. While serving a vanguard Navy, Air Liquide is also innovating. We have designed an oxygen and nitrogen production unit unlike any other in the world. More broadly, we manufacture gas production, storage, and regeneration systems for submarines and surface vessels and work on pioneering projects using our expertise in hydrogen and nitrogen.
