CNG

 Compressed fossil fuel (CNG) (methane stored at high pressure) could be a fuel that may be utilized in place of gasoline, fuel and liquefied petroleum gas (LPG). CNG combustion produces fewer undesirable gases than the aforementioned fuels. as compared to other fuels, gas poses less of a threat within the event of a spill, because it's lighter than air and disperses quickly when released. Biomethane — refined biogas from anaerobic digestion or landfills — are often used. CNG is employed in traditional gasoline/internal combustion engine automobiles that are modified or in vehicles specifically manufactured for CNG use, either alone (dedicated), with a segregated gasoline system to increase range (dual fuel) or in conjunction with another fuel like diesel (bi-fuel)
