It's bad enough for some propeller planes to be referred to as being powered by rubber bands. Now the cynics might begin having a dig at industrial aircraft flying on whatever from cooking oil to liquefied algae.
With the civil air travel market under increasing pressure from increasing oil rates and environmental legislation, the race is on to discover viable options to traditional kerosene and these so far seem to come down to different types of biofuel.
Not surprisingly, the very first trials of alternative fuel were initiated by British aviation pioneer, Sir Richard Branson, whose Virgin Atlantic began London to Amsterdam flights with limited biofuel use in 2008. This was rapidly followed by Lufthansa and Air New Zealand who each used various blends of routine fuel and bio derivatives including some from made from jatropha curcas which can grow in soil considered too poor for growing mainstream foods.
Jatropha is a genus of approximately 175 succulent plants, shrubs and trees (some are deciduous, like Jatropha curcas), from the household Euphorbiaceae.
In 2007 Goldman Sachs cited Jatropha curcas as one of the best prospects for future biodiesel production. It is resistant to drought and pests, and produces seeds including 27-40% oil.
Recently, US aerospace giant Boeing, Brazilian aeronautical major Embraer and the Sao Paulo state Research Support Foundation relocated to perform research and development into using biofuels to power jet airliners. It was reported that Brazilian airlines Azul, Gol, TAM and Trip would function as tactical specialists for the project.
The most recent airline to begin exploring with brand-new fuels is the Alaska Air Group which has actually carried out internal US flights using a mix of 80 % petroleum based fuel and 20% biofuel made from cooking oil. This mix, it is claimed, can cut hazardous emissions by 10%.
One really motivating development has actually been the relocation away from biofuels which complete head on with food consumers thus avoiding a cost spiral. Not so long back, a surge in usage of in cars and trucks caused a spike in maize prices as US farmers diverted too much corn to fuel processing.
Hopefully in the future, airline companies and drivers will focus biofuel consumption on non-food sources such as jatropha and algae. It would be a mixed blessing certainly if some individuals wound up starving just to please somebody else's green qualifications.
