Why CNG is not used for cooking food?

For cooking food in normal home stoves we require pressure around 21 mbar. And this is much lower than atmospheric pressure so you will have to use pressure regulator before stove to decrease the pressure to 21 mbar. While CNG is used mostly on vehicles which has pressure between 200 to 250 bar.

In respect to this, why CNG gas is used in vehicles?

Compressed natural gas (CNG) (methane stored at high pressure) is a fuel which can be used in place of gasoline (petrol), Diesel fuel and propane/LPG. It is safer than other fuels in the event of a spill, because natural gas is lighter than air and disperses quickly when released.

Do CNG vehicles get better gas mileage?

One GGE of natural gas produces an equal amount of energy as a gallon of gasoline. Therefore it gets the exact same gas mileage. However, a GGE of natural gas costs significantly less (I pay $1.39). For example, the gas mileage for my 2011 CNG Tahoe is the same as its gasoline counterpart: 21 MPG on the highway.

Is compressed natural gas cheaper than gasoline?

According to the Environmental Protection Agency, NGVs pave the potential to emit 25 percent less greenhouse gases than diesel-powered vehicles. Best of all, natural gas is cheaper — $1.50 to $2 less per gasoline gallon equivalent, according to NGVAmerica.
