1. Other Alternative Fuels

2.  Natural gas (compressed or liquefied)  Liquefied petroleum gas (propane)  Hydrogen  Coal-derived liquid fuels

3. Natural Gas  Natural gas is a mixture of hydrocarbons, mainly methane, and is produced either from gas wells or in conjunction with crude oil production.  Natural gas is consumed in the residential, commercial, industrial, and utility markets.  Natural gas can either be stored onboard a vehicle as compressed natural gas (CNG) or as liquefied natural gas (LNG).  Natural gas can also be blended with hydrogen.

4. Propane  Propane or liquefied petroleum gas (LPG) is a popular alternative fuel choice for vehicles.  Propane is produced as a by- product of natural gas processing and petroleum refining.

5. Hydrogen  The simplest and lightest fuel is hydrogen gas.  Hydrogen may contain low levels of carbon monoxide and carbon dioxide  Hydrogen can be produced using diverse, domestic resources including fossil fuels, such as natural gas and coal, nuclear; and biomass and other renewable energy.

6. Methanol  Methanol is produced from natural gas in production plants with 60% total energy efficiency.  Methanol can be made with any renewable resource containing carbon such as seaweed, waste wood and garbage.  Methanol fuel cells will greatly reduce carbon dioxide emissions for vehicles and virtually eliminate smog and particulate pollution.

7. Answer the following in your notebooks and print the file.  Which alternative fuel is also called propane?  Which alternative fuel can be compressed or liquefied?  Give 3 examples of renewable resources.  Research from the internet, newspaper or magazine about the use of (any) alternative fuel. Print or cut the article and make a summary about what you have read.
