What does the abbreviation CNG stand for?

The abbreviation CNG stands for Compressed Natural Gas. This term refers specifically to natural gas that has been compressed to a fraction of its volume for storage and transport. Natural gas primarily consists of methane, a clean-burning fossil fuel that is often used as an alternative to gasoline or diesel in vehicles.

Using the term "compressed" is significant as it highlights the process through which natural gas is stored, allowing it to occupy a smaller space. This compression enables efficient transportation in specially designed vehicles, including trucks dedicated to delivering natural gas. The focus on "natural gas" also indicates that it is sourced from geological formations or as a byproduct of oil extraction, underscoring its role as a crucial energy resource.

The other options do not accurately represent the term CNG or its significance in the context of energy and fuel. Therefore, understanding what CNG stands for is fundamental for anyone working in the field of compressed natural gas, particularly for delivery truck drivers who engage with the fuel daily.
