Natural gas is mainly composed of methane (CH4) accounting for 85% and about 10% ethane (C2H6), the rest is a small amount of propane (C3H8), butane (C4H10) and contains only one carbon atom, so when burned Natural gas emits 20% less CO2 and 50% less NOx than gasoline. This gas is a clean fuel and does not pollute the environment. Natural gas is difficult to burn and lighter than air, so it spreads quickly and rises high.
Compressed natural gas is a clean alternative to other types of energy. It is composed of clean compressed natural gas at a pressure of 3000 or 3600psi.
