USAF C-17 makes first ever transcontinental flight on synthetic fuel blend
In the search for renewable and alternative aviation fuels, the US Air Force (USAF) completed the first ever transcontinental flight of an aircraft using a blend of regular aviation and synthetic fuel. These synfuels can be produced from virtually any type of carbonaceous feedstock, including any type of renewable biomass.
A C-17 Globemaster III using the synthetic fuel blend lifted off shortly before dawn at McChord Air Force Base, Wash., and arrived in the early afternoon at McGuire AFB, N.J., where it was greeted by Secretary of the Air Force Michael W. Wynne, New Jersey Rep. Jim Saxton, and a number of officials from both the airline and energy industries.
Synthetic (bio)fuels are obtained from the gasification of carbonaceous feedstocks, after which the syngas is then liquefied via Fischer-Tropsch (FT) synthesis. The process can use both biomass (biomass-to-liquids; BtL), gas (GtL) or coal (CtL). The resulting fuels are ultra-clean, and when biomass is the feedstock both CO2, NOx and SOx emissions are reduced greatly.
The USAF has explicitly stated renewable biomass will be a potential feedstock for these synthetic fuels. By demonstrating their capacity to power large jet airplanes, these fuels are promising as a second generation source of energy for transport:
energy :: sustainability :: biomass :: bioenergy :: biofuels :: gasification :: Fischer-Tropsch :: biomass-to-liquids :: synthetic fuel :: aviation ::
The synthetic fuels have the potential to reduce the United States' dependency on foreign energy sources.
Earlier this year, the U.S. Department of Energy’s National Energy Technology Laboratory (DOE/NETL) and the U.S. Air Force released a study that examines the feasibility of producing 100,000 barrels per day of synthetic jet fuel from coal combined with biomass. The study made a life-cycle analysis and showed the coal+biomass-to-liquids (CBTL) facilities could cut emissions of carbon dioxide (CO2), the primary greenhouse gas, by 20 percent compared to conventional petroleum processes. The resulting fuels would be competitive at current oil prices.

The Air Force is taking a leadership role in testing and certifying the use of synthetic fuel in aircraft. We're working very closely with our Army and Navy colleagues to ensure that this fuel is capable of operating in all of our aircraft. This is especially important because JP-8 military jet fuel is commonly used in the battlefield by the Army and Marines tactical vehicles and generators, as well as our respective aircraft. - Michael Wynne Secretary of the Air ForceThe flight follows successful tests of the fuel blend in C-17 engines in October, and is the next step in the Air Force's effort to have its entire C-17 fleet certified to use the mixture. Air Force officials certified B-52 Stratotankers to use the mixture in August, and hope to certify the fuel blend for use in all its aircraft within the next five years.

The Air Force alternative fuel program is as important to the nation as it is to the Air Force because it keeps focus on alternative fuels by the largest user of fuel in the U.S. government. We must continue to support the research ... to find cleaner, more environmentally friendly fuels that include both renewable and unconventional fuel. - Jim Saxton, New Jersey CongressmanThe fuel blend used by the Air Force mixes JP-8 with the Fischer-Tropsch fuel. The FT process is a method that can convert virtually any carbon-based material into synthetic fuel and was invented by German chemists Franz Fischer and Hans Tropsch developed the method in the 1920s.
