The main component of natural gas is methane (CH4), which accounts for 85% and about 10% of ethane (C2H6), the rest is small amount of propane (C3H8), butane (C4H10) and only one carbon atom, so when burning, natural gas emits 20% of CO2 and less 50% of Nox compared to gasoline so this is a clean fuel without causing the environmental pollution. Natural gas is less flammable and lighter than air, so when it is released, it will spread quickly and fly up.
Compressed natural gas is an alternative clean energy type compared to other types of energy. It is made up of clean compressed natural gas, at a pressure of 3000 or 3600psi.
