Now, you might not realize it, but hemp biodiesel is also burnable (but suffers the same issue regarding freezing). Perhaps this oil will allow for a blend that is equivalent to A1.
NZ airline flies jetliner partly run on veggie oil
WELLINGTON, New Zealand (AP) -- A passenger jet powered in part by vegetable oil successfully completed a two-hour flight Tuesday to test a biofuel that could lower airplane emissions and cut costs, Air New Zealand said.
One engine of a Boeing 747-400 airplane was powered by a 50-50 blend of oil from jatropha plants and standard A1 jet fuel.
This year has seen an unprecedented push for alternative fuels by airlines, which were slammed by skyrocketing oil prices earlier in 2008 and are now bracing for a falloff in air travel in the face of a global economic slowdown.
While Air New Zealand couldn't say whether the blend would be cheaper than standard jet fuel since jatropha is not yet produced on a commercial scale, the company expects the blend to be "cost competitive," according to company spokeswoman Tracy Mills.
Biofuels were once regarded as impractical for aviation because most freeze at the low temperatures encountered at cruising altitudes. But tests show jatropha, whose seeds yield an oil already used to produce fuels like biodiesel, has an even lower freezing point than jet fuel.
