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