Committed to the energy transition

As part of its contribution to the energy transition challenge, Air Liquide drives innovation in clean mobility and offers natural energy sources to replace fossil fuels.

Hydrogen energy

Hydrogen offers a number of benefits for clean transportation. Used in a fuel cell, it combines with oxygen from the air to produce electricity, with water as the only byproduct. Hydrogen does not generate any pollution at the point of use: zero greenhouse gas, zero particle and zero noise. This energy brings a concrete response to the challenges of clean mobility in urban areas and helps to improve air quality.

Air Liquide has already installed 100 hydrogen stations in the world, including a dozen in France, 6 in Japan, more than 12 in Germany and a new network (under construction) of 12 stations in the northeast United States.

Air Liquide also supports the growth of the Paris hydrogen taxi fleet “Hype”. This fleet, deployed in late 2015 by the start-up STEP (Société du Taxi Électrique Parisien) in partnership with Air Liquide, already counts 75 hydrogen-powered vehicles and plans to deploy a total of 200 by the end of 2018.

Air Liquide develops technologies and know-how across the full span of the biomethane value chain for a sustainable transport, from biogas supply and purification for biomethane production to distribution to the final client with bio-NGV (Natural Gas for Vehicle) or clean multi-energy stations (NGV, bio-NGV, liquid nitrogen for cold transportation). Bio-GNV is a clean and renewable energy that reduces CO2 emissions by 90% and noise by up to 50% compared to diesel.

Biomethane is produced from Air Liquide's purification and liquefaction technologies that make it possible to recover all biogas (organic waste, agricultural waste, sewage sludge, etc.) and inject it into the gas network, as well as produce clean fuel for vehicles or renewable hydrogen.

Air Liquide operates more than 60 biomethane stations in Europe, mainly in France, Sweden, Norway and the United Kingdom, and 10 biomethane production units in the world: Europe, China and the United States. Therefore, Air Liquide is the world leader in the production of biomethane with a capacity of 60 MW, or 500 GWh per year.

Air Liquide provides solutions for biogas upgrading and biomethane liquefaction.

Player of deep tech

As a player of the deep tech sector, Air Liquide commercializes technologies dedicated to Space, Aerospace and scientific exploration.


Air Liquide has established its reputation in the field of space thanks to its expertise with rocket launchers (ground resources and Ariane launchers), in the design of cryogenic equipment for satellites as well as space exploration (MTG, Herschel, Planck, Melfi, Curiosity, ExoMars, etc.). Air Liquide continues to develop new technologies for the future Ariane 6 launcher or for electric propulsion for satellites and its projects in connection with space exploration.


Thanks to its expertise in gas separation and control techniques, Air Liquide contributes to these developments by designing systems for the generation, storage, and distribution of gases, for both onboard and ground applications.

Scientific exploration

Expert in cryogenics (extremely low temperatures) and gas engineering, Air Liquide is recognized as a partner of scientific research. Air Liquide designs and supplies cold production, liquefaction, and cryogenic fluid storage and distribution systems for laboratories and large scientific equipment.
