Aviation biofuel…avant garde and a positive direction in curbing costs and ensuring sustainability.
“But aviation is making an important step in breaking free of its petroleum dependence through biofuel.
The ethanol that is typically used in cars—fuel alcohol refined from grain or sugar cane—would not work in aviation, at least with today’s jet engines, because its energy density (the power it packs per gallon or liter) is too low. But numerous start-up companies around the world have been working with a very different fuel derived from oils that have been extracted from plants, animal fat, or grease. The oils are treated with hydrogen to produce HRJ, synthetic kerosene that is chemically the same as jet fuel. Only carbon dating would reveal that it is not made from fossil fuel.”
