Thigpen Energy LNG and CNG Virtual Pipeline Equipment

What is the difference between LNG and CNG?

Thigpen Energy provides virtual pipeline solutions for both LNG and CNG applications across North America. Thigpen Energy’s solutions are 100% mobile and turn-key.

The two different ways that natural gas is stored (and supplied) are referred to as “LNG” (Liquified Natural Gas) and “CNG” (Compressed Natural Gas). The basic differences between these types of natural gas storage are:


  • Natural gas in its cryogenic liquid form
  • Stored at -260F (-162 C) at atmospheric pressures
  • LNG can be hauled long distances from the liquefier while remaining economical


  • Pressurized natural gas
  • Stored at pressures of 3,000 (non-North America standard) to 3,600 psi (North America standard)
  • For fleet use, CNG stations must be near a pipeline network

Both LNG and CNG are less dense forms of energy than petroleum-based liquid fuel. Relative to one gallon of diesel, LNG = 1.7 DGE and CNG = 3.8 DGE. According to information provided by the US Energy Information Administration, the density ratio of gasoline, LNG, and CNG to diesel are:

Other variances between LNG and CNG are storage capacity and weight. The following table shows those differences.
