Natural gas is a clean burning fuel with minimal NOx, SOx, and particulate emissions.
When used as a transportation fuel, natural gas is either compressed or liquefied to increase its energy density and allow for sufficient on-board storage to give the means of transportation an acceptable range of operation. The tables below illustrate which modes of transportation are best suited to use LNG and CNG.
Compressed Natural Gas – CNG
CNG is natural gas that is:
- Compressed at a high pressure to reduce its volume by up to 300 times compared with natural gas at a normal pressure.
- CNG is ideal for passenger cars, pick-up trucks, cube vans, buses, shuttles, short-haul tractor-trailers, dump trucks, medium and long haul trucks, and refuse trucks.
Liquefied Natural Gas – LNG
LNG is a natural gas that is:
- Cooled to a liquid state at -162 degrees Celsius to reduce its volume by 620 times compared with natural gas at normal pressure.
- LNG is ideal for ferries, ships, rail, long-haul trucks, mining applications and industrial uses.
