produced by natural gas under similar conditions An alternative method suggested for H 2 storage/transportation is to convert it into solid metal hydrides, MH 2 .

Alternative Fuels Hydrogen gas is most efficient and clean fuel It produces the most energy per gram, Transportation and storage are difficult It requires a much large fuel tank than gasoline; May be compressed into liquid form, but poses explosion hazard An alternative way is to convert it into a solid metal hydride (MH 2 ) one that is able to release H 2 when heated. Most likely the hydrogen will be used to power fuel cells that will be installed in automobiles

Alternative Fuels Oil shale Shale rocks contain complex HC called kerogen Huge deposits in western states, especially Colorado; Kerogen is not fluid like petroleum - cannot be pumped; Rocks containing fuel must be heated to >250 o C to decompose the kerogen into smaller HC molecules; Process produces large quantities of waste rocks a negative environmental impact.

Alternative Fuels Ethanol: Produced by fermentation of sugar (from sugar cane or corn) Pure ethanol produces about 27 kJ/g of energy Use as fuel supplement Added to gasoline as gasohol (which contains ca. 10% ethanol) Pure ethanol not suitable for motor fuel in USA, especially in winter, because it does not vaporize easily in cold climate. Pure ethanol is widely used as motor fuel in Brazil where the climate is warmer.

Alternative Fuels Methanol: Methanol produces about 20 kJ/g of energy when completely combusted It has been used in race cars as a mixture of 85% methanol and 15% gasoline. California is evaluating methanol as motor fuel Arizona and Colorado are considering similar step.
