Air Liquide to build a world-scale CO2 capture unit to
contribute to Rotterdam’s industrial basin decarbonization
Air Liquide has announced that it will build, own and operate a world-scale carbon capture unit in the
industrial basin of Rotterdam, the Netherlands, leveraging its proprietary Cryocap™ technology. The new
unit will be installed at the Group’s hydrogen production plant located in the port of Rotterdam and will be
connected to Porthos, one of Europe’s largest carbon capture and storage infrastructure aiming at
significantly reducing CO2 emissions in this large industrial basin.

Air Liquide will capture the CO2 from its existing world-scale hydrogen plant in the port of Rotterdam,
leveraging CryocapTM, a technological solution for CO2 capture using a cryogenic process. Captured CO2 will
then be transported through the Porthos infrastructure, which is currently being developed, and permanently
stored in depleted gas fields in the North Sea, approximately 20 kilometers off the coast. The carbon capture
unit will be operational in 2026. Through this project, Air Liquide will be able to supply hydrogen that will be
significantly decarbonized, to its long-term customers, as contracted.

The Porthos infrastructure overall will enable to reduce emissions by 2.5 million tons of CO2 per year –
equivalent to around 10% of the current Rotterdam industry CO2 emissions. The European Union has
recognised Porthos as a major cross-border infrastructure project, contributing to the achievement of energy
and climate policy objectives, and has included Porthos to the list of Project of Common Interest.

Emilie Mouren-Renouard, member of Air Liquide’s Executive Committee and Chief Executive Officer of the
Europe Industries Hub, said: “We are pleased to take another concrete step to contribute to the
decarbonization of one of Europe’s largest industrial basins while participating to the development of
Porthos. This new world-scale CO2 capture unit illustrates our expertise and commitment to implementing
decarbonization solutions, both for our customers and our own assets, in line with the Group’s ADVANCE
strategic plan to reduce its CO2 emissions by 33% by 2035.”
