Isobuta-what? Alaska partners with Gevo to bring biofuel to commercial flights
Share
Alaska Airlines today operated the first commercial flights using a 20 percent blend of renewable alcohol-to-jet biofuel produced by Gevo, a renewable chemical and biofuel company. The two flights originated in Seattle with destinations of San Francisco and Washington D.C.
Alcohol-to-jet biofuel was just approved for use by ASTM International in March 2016 and is the first aviation biofuel to be certified and approved since 2011.
Fuel made of isobuta-what?
To make renewable jet fuel, Gevo starts with a non-edible field corn. First, Gevo’s process captures the protein and fiber in the corn to produce a high value animal feed product. Then, the starch (or sugars) in the corn kernels is fermented into isobutanol. This fermentation process is similar to that used to make ethanol – the type of alcohol used in alcoholic beverages. Isobutanol is then chemically converted through a Gevo-patented process into a renewable jet fuel. What they’ve created is the first carbohydrate-based, sugar-fermented fuel.
