A study on greenhouse gas emissions for biojet fuels produced from forest industrial residues has been published by Lovisa Björnsson and Karin Ericsson
In 2021, the Swedish Government introduced a greenhouse gas (GHG) emission reduction mandate of 27% by 2030 for aviation fuel sold in Sweden, forcing fuel suppliers to blend in increasing amounts of biojet fuel in fossil jet fuel. To limit the demand for biojet fuels, the GHG emissions must be low.
In this study, several emerging technologies for the production of biojet fuels from wood were investigated. The results show that all the production chains studied can deliver biojet fuels with 89–91% lower GHG emissions than fossil jet fuels.
There is currently no production of biojet fuel in Sweden, but several emerging wood-fuel-based production chains are being investigated on a pilot or demonstration scale. The results of this study showed that in a region with high availability of forest industrial residues and access to heat and power with low GHG emissions all these production chains could contribute to reaching the reduction mandate targets.
