Natural gas is stored under high pressure as Compressed Natural Gas (CNG). CNG is used for power generation. It is also a less polluting fuel used for automobiles. The great advantage of CNG is that it can be used directly for burning, in homes and factories. It also has a higher calorific value than most of the other fuels.
