Sittard, The Netherlands, Stamicarbon, the innovation and license company of MAIRE Group, has signed a license agreement with its customer in the USA to develop a basic engineering design package for a 450 MTPD green ammonia plant. The plant will be based on the state-of-the-art NX Stami Green Ammonia™ technology and is expected to start up in 2026, producing green ammonia to be used as feedstock for nitrogen-based fertilizers. 

NX Stami Green Ammonia™ enables environmentally friendly ammonia production by deriving nitrogen from the air and using hydrogen obtained by water electrolysis instead of the steam reforming of fossil fuels. As a result, this technology offers a sustainable and highly competitive alternative to conventional gray processes, paving the way for producing green fertilizers from renewable energy sources.  

“NX Stami Green Ammonia™ is at the heart of Stamicarbon’s innovation program, and we are excited to see this technology implemented in several projects around the world,” said Pejman Djavdan, Stamicarbon CEO. “It represents a significant leap forward for the production of green fertilizers based on renewable resources."
