Air Force to fly on synthetic fuel?
The government's biggest energy user is considering a cheaper, cleaner fuel to fire its jet engines.

The US Air Force is experimenting with a synthetic fuel that could become a cheaper fuel-alternative for the entire US military and even commercial aviation, officials say.
As the cost of a barrel of oil approaches $100 and US reliance on foreign oil sources grows, the Air Force, the single biggest user of energy in the US government, wants to find a cheaper alternative. Air Force officials think they may have found it in a fuel that blends the normal JP-8 fuel, currently used for the military's jet engines, with a synthetic fuel made from natural gas and liquid coal.
The 50-50 blend is less expensive – between $40 to $75 per barrel – and it burns cleaner than normal fuel. The synthetic fuel is purchased from US-based suppliers and then blended with the military's JP-8 fuel.
"We're making sure the Air Force is ahead of the curve so we can utilize this domestic resource instead of having to be both dependent on foreign sources and send dollars offshore instead of spending the dollars here in the US," says Kevin Billings, a deputy assistant secretary of the Air Force helping to oversee the initiative.
Last week, on the 104th anniversary of the Wright Brothers' first flight, the Air Force flew a C-17 Globemaster III from Washington state to New Jersey, the first transcontinental flight using the synthetic fuel. The flight was an attempt to demonstrate that pilots could fly the plane, considered a "workhorse" of the Air Force fleet, using "syn-fuel" without degrading the performance of the plane's engine.
The flight went well, officials say.
"It was completely unremarkable, which is exactly what we wanted to have happen," says Mr. Billings.
The flight followed a similar demonstration with a B-52 Stratofortress bomber last year. The fuel was then certified for use in the B-52 this summer. The service hopes to have all its planes certified to run on the fuel within the next five years. And by 2016, the Air Force hopes to meet half their US demand for fuel using the synthetic blend, first used in the 1920s, but further developed during World War II.
The Air Force would like to increase the amount of synthetic fuel it uses by that time, but recognizes that the private sector's push to get there will largely determine how fast the Air Force can move towards its goal or accelerate beyond it.
"[T]he market isn't moving fast enough yet for us to move any quicker," says William Anderson, assistant secretary of the Air Force for installations, environment and logistics.
