However, liquefying natural gas requires it to be stored in tanks and kept at temperatures of minus 260 degrees Fahrenheit. The extreme temperatures require investment in refueling infrastructure and special handling. Methanol is an odorless, clear alcohol fuel that has been used as an automobile fuel for years because of its energy-efficiency. The power, acceleration and overall vehicle performance of methanol-fueled vehicles is comparable to gasoline powered cars. Methanol is often added to gasoline to reduce the emissions from traditional gasoline.
Ethanol is also a liquid alcohol fuel that is manufactured mainly from corn.
Ethanol vehicles emit fewer pollutants than gasoline-powered vehicles, and many state and federal laws provide tax incentives for producing the fuel. A Major drawback of pure ethanol is its cost and the lack of refueling infrastructure. However, the vehicles currently are expensive and have a short travel range between recharging. Reformulated gasoline is a new blend of gasoline in which the composition has been altered to reduce automobile emissions. The gasoline can be used in all traditional gasoline vehicles, and it emits fewer ozone-forming pollutants.
