What is CNG?2020-08-26T18:53:15+00:00


When natural gas travels through pipelines, it stays in gaseous form at

moderate pressure. But when natural gas is used in vehicles, its volume

must be reduced. This is done in one of two ways.

Compressed Natural Gas     and

Compressed to 1% of regular volume

Injected from a compresser

Stored onboard a vehicle as gas               at 3600 psi

Liquefied Natural Gas

Cooled to -260° F and condensed             into liquid form

Shipped in specialized vehicles

Dispensed through a fuel nozzle

CNG already fuels thousands of vehicles across the U.S, including

passenger vehicles,


and heavy trucks.

CNG is at the forefront of green vehicle fuels. When the CNG is produced from

renewable natural gas like that produced by San Joaquin Renewables, greenhouse

gas emissions can be reduced by up to 193% compared to diesel!

When compared to diesel, CNG has emissions of:


less particles

less NOx

less CO

less VOCs

less GHG*

*Based on lifecycle analysis by US EPA. When combined with carbon sequestration, the reduction may be close to 200%
