Bio Jet Fuel

According to a recent report produced by Australia’s CSIRO, fuels derived from biomass are the only sustainable candidate for substituting current petroleum derived aviation fuels.

Jet fuels must meet stringent technical and safety standards. Synthetic jet fuels with the same properties as petroleum based jet fuel can be made from coal, natural gas or biomass.

These synthetic jet fuels are referred to as ‘drop-in’ fuels because they can be used without changes to engine fuel systems and distribution and storage systems.

Jet fuels produced from coal or gas come with higher greenhouse gas emissions (over 100 per cent higher in the case of coal and while these may potentially be reduced via geological carbon dioxide (CO2) capture and storage (at additional cost), their use would be inconsistent with the aviation sector’s goals for levelling and eventually reducing its greenhouse gas emissions and dependence on fossil fuels.

Fuels derived from biomass are currently the only sustainable candidate for substituting current petroleum-derived aviation fuels. The technical properties of bio-derived jet fuels have been assessed against the jet fuel standards. Currently, a 50 per cent blend of bio-derived jet fuel (FT-SPK5) can be used as a ‘drop in’ fuel which meets or exceeds the jet fuel standards.

The standards have been developed based on specific refining technologies which can be used for many but not all biomass feedstock. The standard for FT-SPK has been in operation since 2009.

A second refining system covering most remaining classes of biomass is expected to be approved via ASTM International7 processes in 2011 for use in up to 50 per cent blends.

Having been successfully trialled by a number of major airlines around the world, algal biomass is regarded as a sustainable potential new source of feedstock for the production of bio jet fuel.
