Airplanes powered by coal -- at first blush it sounds about as attractive as the toddler chainsaw. But Accelergy in Houston says it has come up with a way to convert the ubiquitous rock into an economical, clear, and arguably clean form of jet fuel.
The company will initially try to sell fuel to the U.S. military -- the Air Force has already begun initial testing -- and has also started to field inquiries from China and some commercial aircraft and engine manufacturers. Biomass can also be substituted for coal, or at least part of it, in the recipe, depending on the desired characteristics of the final fuel.
The Department of Defense will likely set its standards for synthetic jet fuels in 2013, and CEO Tim Vail claims that Accelergy's fuel will be able to meet those standards.
