The highest energy consumption in Swedish agriculture is associated with the production of nitrogen fertilisers. At present, nitrogen fertilisers are mainly produced from natural gas and coal in the Haber-Bosch process. This project is examining the possibility of producing nitrogen fertilisers from renewable resources, for example via gasification of biomass.
Utilising gasified straw or designated energy crops for nitrogen production could help Swedish agriculture to significantly reduce its greenhouse gas emissions.
