The NASA is investigating the subject of the use of alternate fuels or aviation fuels derived from energy resources other than naturally occurring crude oil. This paper presents the results obtained thus far of investigations conducted by and for the NASA's Langley Research Center, aimed at assessing the potentials of coal-derived aviation fuels. Coal has been identified as one of the more plentiful remaining U. S. energy resources (an order magnitude greater than crude oil) and was selected as the energy source for this investigation. The fuels considered were synthetic aviation kerosene, liquid methane, and liquid hydrogen. Synthetic aviation kerosene was selected for study because the use of such a fuel is likely to cause fewer changes to the present air transportation system than would other fuels. Liquid methane and liquid hydrogen were selected for study because of their high energy content per kilogram. The Langley investigations have included the areas of fuel production, air terminal requirements for aircraft fueling, and the performance characteristics of aircraft designed to utilize alternate fuels. In the fuel production studies the energy requirements associated with the production of each of the three selected fuels have been determined, as have estimates of the fuel prices.
