LIQUEFIED NATURAL GAS

LIQUEFIED NATURAL GAS (LNG)

Liquefied Natural Gas (LNG) is a clear, colourless and non-toxic liquid which forms when natural gas is cooled to -162ºC (-260ºF). The cooling process shrinks the volume of the gas 600 times, making it easier and safer to store and ship. When LNG reaches its destination, it is turned back into a gas at regasification plants. Once it has been warmed to become natural gas, it is dispersed through pipelines for use by homes, businesses and industries where it is burnt for heat or to generate electricity. LNG is now also emerging as a cost-competitive and cleaner transport fuel, especially for shipping and heavy-duty road transport
