Airlines Focus On Biofuel Trials Gather Momentum
It's bad enough for some propeller planes to be referred to as being powered by rubber bands. Now the cynics could begin having a dig at commercial airplane flying on everything from cooking oil to liquefied algae.
With the civil air travel market under increasing pressure from rising oil costs and ecological legislation, the race is on to find viable alternatives to conventional kerosene and these so far seem to come down to numerous kinds of biofuel.
Not surprisingly, the first trials of alternative fuel were started by British aviation pioneer, Sir Richard Branson, whose Virgin Atlantic started London to Amsterdam flights with limited biofuel use in 2008. This was quickly followed by Lufthansa and Air New Zealand who each utilized different blends of routine fuel and bio derivatives consisting of some from made from jatropha which can grow in soil considered too poor for growing mainstream foods.
Jatropha is a genus of roughly 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 very best prospects for future biodiesel production. It is resistant to dry spell and pests, and produces seeds consisting of 27-40% oil.
Recently, US aerospace giant Boeing, Brazilian aeronautical major Embraer and the Sao Paulo state Research Support Foundation transferred to perform research and advancement into making use of biofuels to power jet airliners. It was reported that Brazilian airline companies Azul, Gol, TAM and Trip would function as tactical consultants for the task.
The current airline to start try out new fuels is the Alaska Air Group which has actually performed internal US flights using a blend of 80 % petroleum based fuel and 20% biofuel made from cooking oil. This mix, it is claimed, can cut damaging emissions by 10%.
One actually encouraging development has been the move away from biofuels which compete head on with food consumers thereby avoiding a price spiral. Not so long earlier, a rise in usage of biofuels in cars triggered a spike in as US farmers diverted too much corn to fuel processing.
Hopefully in the future, airlines and vehicle drivers will focus biofuel intake on non-food sources such as jatropha and algae. It would be a combined blessing indeed if some people ended up starving just to please another person's green credentials.
