Gulfstream G450 crosses the Atlantic on 50/50 biofuel-jetfuel blend   Leave a comment

The use of biofuel in aerospace is reaching viability. The ideal situation will be when biofuel feedstock does not have to complete with foodstock.

 

Honeywell’s biofuel is derived from camelina, a dedicated energy crop that grows in rotation with wheat, which reduces competition with the food market. According to Honeywell, the biofuel offers up to an 85 percent reduction in net emissions compared to petroleum-based fuels. Additionally, it is manufactured using the same hydro-processing technology already used for the manufacture of today’s transportation fuels, and can be mixed with petroleum-based fuel. Furthermore, tests have shown that it can be used for military or commercial applications without need for aircraft or engine modification.

The initial technology was driven by a 2007 contract from the U.S. Defense Advanced Research Projects Agency (DARPA) to produce renewable military jet fuel. Honeywell has experimented with biofuels made from camelina, jatropha and algae in sixteen biofuel test flights so far, and have produced more than 700,000 U.S. gallons (264,979 liters) of Honeywell Green Jet Fuel to date. The feedstock for the transatlantic flight was grown and harvested by Sustainable Oils, a U.S.-based producer of camelina-based technology.
