Product Description

What is LNG?

Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport.

Improved Air Quality. Natural gas is the cleanest-burning fossil fuel, therefore vehicles running on LNG produce lower levels of toxic emissions and air pollution than equivalent diesel engines. Nitrogen Oxides (NOx) emissions are reduced by 40-50% and articulate Matter (PM) emissions are reduced by approx 80%.

LNG Cylinders Benefits

The differences between compressed natural gas (CNG) and liquefied natural gas (LNG) are the methods of production and storage.
Both fuels are primarily methane (CH4). LNG is natural gas 'frozen' to less than -162o Celcius (-212o Fahrenheit) to liquefy it. The advantage of liquefaction over compression is that the fuel is at a higher density, meaning more energy is contained in the same space - LNG is roughly 600 times the density of natural gas at standard pressure.
In general, LNG is more commonly used for heavier vehicles whereas CNG is used for lighter vehicles. This is not a hard and fast rule though and both fuels may be used in either class of vehicle.
Once the gas is liquefied, it must be kept cold or it will revert to its gaseous state, thus LNG cylinders are designed in a
similar fashion to a thermos flask, (i.e. with substantial insulation). This design allows for the fuel to be kept cold for two
weeks or more.
