What’s the difference between CNG and LNG?

In short, Compressed Natural Gas (CNG) is made by compressing natural gas to 1/100th of its normal volume. Liquefied natural gas (LNG) is a process where natural gas is cooled to a liquid 1/600th the volume of natural gas. Both processes allow natural gas to be more easily stored and transported.

Because of the abundance of natural gas in America, CNG and LNG are also a domestic alternative to importing oil as they can be used as a vehicle fuel, offering life cycle greenhouse gas (GHG) emissions benefits and reduced tailpipe emissions.

In Colorado, our state is a net exporter of natural gas and able to sell the excess gas we can’t use. Many have recognized the benefits of exporting LNG overseas. It has the potential to bring jobs, stimulate the economy, and strengthen our nation’s ability to leverage our energy security position when it comes to international affairs. By 2035, LNG exports in Colorado will create up to 11,366 new jobs and $1.8 billion in economic growth. (Source: ICF International)

In 2013, Noble Energy Inc., one of the biggest oil and natural gas producers in the Denver-Julesburg Basin north of Denver, announced plans to build Colorado’s first dedicated liquefied natural gas (LNG) plant. (Source: Denver Business Journal)
