Boeing plans Biofuel flight
#12
For the mid-term, the best solution for large turbine airlines is alternatively produced Jet A (from coal or natural gas). This sort of fuel is so similar to petroleum jet A that no aircraft mods should be required. The US Air Force has actually embarked on wholesale project to shift to 50%+ artificial Jet A in the next few years. They are doing this mainly for national security reasons to ensure they have a fuel supply in case we get cut off, but it's really good news in that they are laying the groundwork for commercial aviation to follow.
Long-term we may be able to come up with an alternative, non Jet A, fuel which is suitable for airliners, but there are several hurdles:
- The industry and/or government must decide what fuel to use.
- New aircraft must be designed and built. Kerosene burners will not be able to function effectively using anything which is much different from Jet A.
- Fuel supply infrastructure must be developed.
All of this is phenomonally expensive (hundred$ of billion$). The only incentive to using non-kerosene instead of alternative Jet A would be emissions I think. It's possible that large turbine aircraft will always use petroleum an/or alternative Jet A...it has so many characteristics which make it ideal for large airplanes.
