Relationship Between Greenhouse Gas Emissions and Natural Gas Vehicles

A natural gas vehicle or NGV is an alternate fuel vehicle that applies contracted natural gas (CNG) or, less normally, liquefied natural gas (LNG) as a clean alternative to other automobile fuels. Worldwide, there are roughly five million NGVs as of 2006, with the largest number of NGVs in Argentina, Brazil, Iran, Pakistan, and Thailand. In Europe they are popular in Germany and Italy.

NGV’s can be refueled anyplace from existing natural gas lines. This makes home fueling stations that exploit into such lines possible. A company called FuelMaker has initiated such a system known as “Phill”, which they have built up in partnership with Honda.

Existing gasoline-powered vehicles may be converted to CNG. An expanding number of vehicles worldwide are being manufactured to run on CNG (Honda Civic, Samand). GM do Brasil introduced the MultiPower engine in August 2004, which was capable of using CNG, alcohol, and petrol as fuel.

The Relationship between Chemical Industry and Energy

The relationship between chemical industry and energy is very close. For instance, many different kinds of energy are the products of fossil fuels and its derivatives through chemical processing. Energy can be divided into primary energy and secondary energy. Primary energy includes heat energy and motive power which we get from nature and apply them to our industry directly, such as coal, petroleum, natural gas, hydroenergy and nuclear energy. Energy like coal, oil and natural gas belongs to fossil fuel. Among all the varieties of energy, fossil fuel is consumed at the largest account. In 1985, the whole amount of primary energy consumption all over the world reached 10610 megatons. Among this consumption account, coal reached 29.7 percent; petroleum 39.9 percent; natural gas 21.1 percent; hydroenergy 7.7 percent; and nuclear energy 4.9 percent. Secondary energy (electricity excepted) mainly means the fuel got from primary energy through chemical processes. For example, liquidfuel like gas, diesel oil, jet fuel and heavy oil are refined from petroleum. They are all important goods and materials for modern transportation and military affairs such as automobiles and airplanes. Secondary energy also includes gaseous fuel got from coal processing used for industry and civilian life and artificial petroleum obtained from coal and oil shale.
