As this publication has reported several times, biofuel tests in jets and other planes have proved that the lower-emissions fuels are as efficient or more efficient than their fossil fuel counterparts. Since the emissions are released so high in the atmosphere, they’re much more potent than similar emissions released at ground level. Discussion of the results of Continental’s January biofuel test flight has begun again at the Paris Air Show, with participants focusing on how best to supply the quantity to biofuel neces sary to significantly cut into the 60 billion gallons of jet fuel burned annually worldwide. In the meantime, Boeing is certifying its Bio-SPK fuel — which the company says could replace up to 70% of their commercial aviation fuel — and expects approval as soon as 2010.
