'Today’s ubiquitous aviation fuel is a kerosene-type fuel called “Jet-A.” Jet-A offers considerable energy per weight and volume, is safe to handle, is designed to ensure prolonged engine life, is compatible with the existing storage and delivery infrastructure, and was historically low-cost.'
'Many alternative fuels pose serious hurdles. For example, biodiesel — thickens considerably at the low temperatures encountered at high altitudes. Alcohols pack comparatively little energy for given weights and volumes. Cryogenic fuels, like liquid hydrogen, pose so many obstacles (for example, they are completely incompatible with the existing infrastructure) that they are unlikely to be practical within the 10-year criterion and, are therefore, not under PARTNER’S consideration.'
