Question

What is the major component of natural gas? Which properties of natural gas make it a safer fuel?

Answer 1

Natural gas is a mixture of various hydrocarbon gas known in scientific names i.e. methane, ethane, propane, and butane. Over 70% of natural gas is formed by methane, the major component.

CNG combustion produces fewer undesirable gases than the fuels mentioned above. It is safer than other fuels in the event of a spill, because natural gas is lighter than air and disperses quickly when released. ... The cost and placement of fuel storage tanks is the major barrier to wider/quicker adoption of CNG as a fuel.
