Liquified Natural Gas

TAD Fuel Plants produce ultra-pure Bio-Methane as Liquified Natural Gas. LNG is easy and economical to store, transport, and dispense. 

Natural gas is mainly used as fuel for generating electricity and heat. Natural gas in compressed form is used as fuel for vehicles which is known as CNG. It is used as fuel for boilers and air conditioners worldwide. This is used for making fertilizers also, mainly ammonia.

LNG - The contemporary fuel

Liquefied Natural Gas (LNG) is an environmentally friendly energy source that emits less carbon dioxide than coal or oil. Natural gas is cooled to minus 162 degrees Celsius which turns it into a liquid. Liquefaction reduces the volume to 1/600 of that of gas and enables it to be transported in large quantities by sea.


LNG offers a unique advantage over CNG for more demanding high-horsepower applications by eliminating the need for a turbocharger. Because LNG boils at approximately −160 °C (−256 °F), by using a simple heat exchanger a small amount of LNG can be converted to its gaseous form at extremely high pressure with the use of little or no mechanical energy. A properly designed high-horsepower engine can leverage this extremely high pressure energy-dense gaseous fuel source to create a higher energy density air-fuel mixture that can be efficiently created with a CNG-powered engine. The end result, when compared to CNG engines, is more overall efficiency in high-horsepower engine applications when high-pressure direct injection technology is used. The Westport HDMI2 fuel system is an example of a high-pressure direct injection technology that does not require a turbocharger if teamed with appropriate LNG heat exchanger technology. The Volvo Trucks 13-litre LNG engine is another example of an LNG engine leveraging advanced high-pressure technology.

Westport recommends CNG for engines 7 liters or smaller and LNG with direct injection for engines between 20 and 150 liters. For engines between 7 and 20 liters either option is recommended. High horsepower engines in the oil drilling, mining, locomotive, and marine fields have been or are being developed. 


LNG has recently been introduced as an alternative to heavy oil as a marine fuel. BHP, one of the largest mining companies in the world, is aiming to commission minerals transport ships powered with LNG by late 2021. Florida East Coast Railway has 24 GE ES44C4 locomotives adapted to run on LNG fuel
