What is LNG?
Liquefied Natural Gas, or LNG, is natural gas that has been liquefied by reducing its temperature to -162ºC. As a result, the fuel density is then increased by a ratio of 600:1. By comparison, compressed natural gas, or CNG, achieves an energy density of 200:1.
LNG is composed primarily of methane (CH4) and has similar physical and chemical properties to pipeline gas. The liquefaction process removes undesirable elements such as water, sulphur compounds and CO2.
The use of LNG as a clean, economical, transport and power generation fuel is well established in countries such as the USA, UK and Spain. In Australia, LNG is the only realistic alternative fuel to diesel in the heavy-duty vehicle market.
LNG is ideally suited to large trucks, typically over 20 tonnes gross vehicle mass (GVM) and refuse haulers, compactors and transit buses.
