Liquefied Natural Gas (LNG)

gas naturale liquefatto

Thanks to its new uses, liquefied natural gas can contribute to the reduction of pollutant emissions

Once extracted, natural gas can be liquefied through a specific cooling process (that brings gas at -160 ° C). The operation engenders a remarkable reduction in volume. In liquid state, Liquefied natural gas (LNG) can be easily stored and transported by sea, thanks to special vessels. In this way the LNG can travel for thousands kilometers and reach the Italian regasification facilities. Once arrived, liquefied natural gas is discharged at a storage facility that takes it back to the gaseous form and makes it available for traditional consumption. The import of LNG through sea allows further diversification of sources of supply, with positive outcomes on national energy security.

LNG also has several alternative uses, thus it could replace traditional fossil fuels in several contexts and significantly reduce pollutant emissions for both maritime and heavy road transport.

Gas contributes to the growth and the sustainable achievement of the objectives of decarbonization at global level


LNG data


  • LNG
  • Pipeline

LNG will play an increasing role for the competitiveness of natural gas and will enable new markets to emerge, favoring the economic development of regions not yet equipped with modern energy systems.

Italy could attract more LNG by developing new regasification capabilities.

Liquified natural gas and the LNG "supply chain"

In order to be transported on LNG carriers, gas is liquefied. The liquefaction temperature of natural gas is approximately -160° C at atmospheric pressure.

LNG is essentially a colorless and odorless fluid with a density equal to approximately half that of water.

The LNG is transported by sea by high technology tankers featuring safety systems and environmental protection quality standards which are among the highest in the world.

Once arrived at its destination, the LNG is unloaded at the import terminal where it is heated and brought to a gaseous state and injected into the pipeline network, once at an appropriate pressure level.
