Air Liquide’s new technology converts ammonia into hydrogen at industrial scale

November 16, 2025 |

In France, Air Liquide announced the successful start-up of what it claims to be the world’s first industrial-scale ammonia cracking pilot unit with a 30 tons per day ammonia to hydrogen conversion capacity at the Port of Antwerp-Bruges, Belgium. 

This technology proven at the industrial scale for the development of world scale ammonia cracking plants enables access to low-carbon and renewable hydrogen for the decarbonization of industry and mobility, the firm said.

This new, proprietary ammonia cracking technology expands Air Liquide’s portfolio for low-carbon and renewable hydrogen production. As part of the successful development of this unit, key proprietary innovations were developed across critical areas including process safety, material testing, advanced catalysis for ammonia cracking, ammonia combustion, and efficient molecule separation.

“The commissioning of our ammonia cracking pilot unit in Antwerp is a key milestone. This is a world’s first which paves the way for new low-carbon hydrogen supply chains,” said Armelle Levieux, member of Air Liquide’s executive committee.
