Energy transition
The recent years have made it a certainty: inaction in the energy transition is more costly than action. For more than a decade, Air Liquide has been anticipating this by developing new sustainable solutions for industry, leveraging its field of expertise and acknowledging the role its essential small molecules could play.
Geopolitical uncertainties, energy supply risks and the growing frequency of extreme climatic events remind us of the urgency to act collectively. We must reduce our dependence on fossil fuels and lower global greenhouse gas emissions. In this context, Air Liquide is working alongside its customers and industrial partners to decarbonize their activities. Discover the Group’s wide range of molecules and technological solutions that make Air Liquide a key contributor to the energy transition.
Our main technologies to accelerate the energy transition
To help tackle the climate emergency, it is crucial to decarbonize production methods. Consequently, Air Liquide has developed a series of cutting-edge technologies to support its industrial customers in their decarbonization while reducing its own emissions.

Porthos, capturing CO₂ to decarbonize Rotterdam’s industrial basin
Air Liquide is one of the four launching customers of the Porthos project, an infrastructure initiative to capture and store the CO₂ emissions of Europe’s largest industrial port. The goal: substantially reduce the environmental footprint of the Port of Rotterdam in the Netherlands thanks to an ambitious Carbon Capture and Sequestration (CCS) solution. Find out more here.
Hydrogen, a key to a successful energy transition
For decades, hydrogen has been used in diverse sectors of industry. Since its use does not emit any greenhouse gases, only water vapor, it can serve as an effective and decarbonized alternative to fossil fuels in many fields of the industry as well as for mobility. As such, hydrogen will play a key part in the energy transition.
Air Liquide Normand’Hy: an electrolyzer project at the heart of the Normandy industrial basin
Air Liquide Normand'Hy is much more than a 200 MW electrolyzer under construction. It is a human, technological and territorial adventure that mobilizes Air Liquide employees and an ecosystem of committed partners. This flagship project illustrates the Group's strategy of promoting hydrogen as a key solution of the energy transition, drawing on more than 60 years of expertise and a strategic partnership with Siemens Energy.

How does hydrogen contribute to the decarbonization of the glass industry?
Glass is made by melting a mixture of silica (contained in sand) or recycled glass – and this requires very high temperatures of around 1,400°C. When used as a combustible instead of natural gas, hydrogen can be an alternative for decarbonization since, during its combustion, it combines with oxygen to only form water vapor. So there is zero emission of greenhouse gases. Learn more here.

Decarbonizing mobility
With heavy mobility responsible for 25% of worldwide CO₂ emissions, Air Liquide firmly believes that hydrogen has a key role to play in accelerating the energy transition. The Group’s expertise in this field dates back more than 60 years. Its technologies are used throughout the hydrogen supply chain, from production to storage and distribution. The Group serves industries from metallurgy to electronics, and from refining to mobility.
Air Liquide is joining forces with both private companies (from major industrial multinationals to startups) and public entities to develop the full potential of hydrogen for reducing CO₂ emissions.
Air Liquide has teamed up with TotalEnergies to create a joint venture (named TEAL Mobility) focused on developing a network of over 100 hydrogen stations across Europe. This network will primarily serve heavy-duty vehicles along major road corridors in France, Benelux, and Germany.
Air Liquide will also invest in a new hydrogen packaging and delivery supply chain to refueling stations along the Seine Axis in France, to support the acceleration of low-carbon mobility. The new packaging site will be supplied with renewable hydrogen from the Air Liquide Normand’Hy electrolyzer with a capacity of 200 MW currently under construction. Learn more here.
Air Liquide is at the forefront of integrating hydrogen into the aviation sector, partnering with key players to develop a global hydrogen ecosystem for more sustainable air travel. Air Liquide is actively developing a hydrogen ecosystem at Incheon Airport in South Korea, in partnership with Airbus, Korean Air, and Incheon International Airport Corporation: two high-capacity hydrogen stations have already been operational since August 2021, fueling hydrogen fuel cell buses, cars, and demonstration trucks with Air Liquide providing a long-term hydrogen supply. The partnership is also developing a roadmap to guide the broader adoption of hydrogen and expand hydrogen infrastructure to other Korean airports.
