Decarbonising the Fertiliser Industry: The Potential Role of Biomass Gasification

P. Gilbert & P. Thornley
Greenhouse gas emissions associated with fertiliser production are increasing as global food demand increases. This study uses life cycle assessment to assess the production of nitrogen (N)­fertiliser from biomass gasification, compared to natural gas steam reforming. Steam reforming is very energy intensive and fertiliser production accounts for approximately 1% of global greenhouse gas emissions. To replace this, biomass feedstock is gasified to produce a H2 rich syngas, which is then combined with N2 to produce...
