What is blue ammonia? 

Blue ammonia is produced from natural gas with carbon capture and storage (CCS). Hydrogen is separated from natural gas through steam methane reforming (SMR) or auto thermal reforming. Carbon capture technologies are used to remove the COgenerated through this process and transport it for re-use or long-term storage. Nitrogen gas is obtained through air separation and then combined with the hydrogen gas to produce ammonia through the Haber-Bosch process.
