From 2026, Air Liquide will capture CO2 from its hydrogen plant in the port of Rotterdam, using its Cryocap technology. The carbon dioxide will then be transported and sequestered under the North Sea.
Air Liquide will therefore be able to supply its customers, under long-term contracts, with hydrogen that has been significantly decarbonised. To achieve this, the company will use its Cryocap technology, a CO2 capture system based on a cryogenic process. The captured carbon dioxide will then be transported via the Porthos* infrastructure, currently under development, before being permanently sequestered under the North Sea, around 20 kilometres off the coast.
This initiative will be roll-out out in 2026 and will combine pipelines (one on land, one underwater), a compressor station and a sandstone storage system. Porthos aims to reduce emissions by 2.5 million tonnes of CO2 per year, around 10% of Rotterdam’s industrial emissions.
*Porthos: Port of Rotterdam CO₂ Transport Hub and Offshore Storage.It was recognised by the European Union as a major cross-border infrastructure project, helping to achieve energy and climate policy objectives. It has thus been included on the list of projects of common interest (PCIs).
