It's a government project. $3 a gallon inclides the "savings" of having X fewer troops to escort fuel convoys in theater, Y fewer KBR contractors actually hauling the fuel and selling it to the Pentagon at no-bid contract prices and Z fewer warships required to rotate off mission for refueling and escorting replenishment ships.
Once you factor all of that in, it's only $3 a gallon!
But really, the operational flexibility this could give the military is amazing and would reduce many of the hidden costs of getting fuel at sea or in theater.
