Jet Fuels. SAJF needs alternative jet fuel specifications, either on their own or when blended with conventional jet fuel. As such, SAJF (blended as necessary) are “drop-in” replacements for conventional jet fuel.
Alternative. SAJF are alternative in that they are produced primarily from nonpetroleum sources of hydrocarbons using a potentially broad range of biochemical and thermochemical conversion processes.
Sustainable. Alternate fuels need to be sustainable both in terms of their ability to reduce net life-cycle carbon emissions relative to conventional alternative jet fuel and in terms of environmental, societal, and economic factors.
