Liquefied natural gas (LNG)

Liquefied natural gas (LNG). Natural gas can be cooled until it becomes liquid and stored in tanks. This reduces the volume about 600 times. For transportation between locations where other means of transportation (such as pipelines) is uneconomic, natural gas can be transported as LNG by ship.

The infrastructure needed for LNG transportation consists of a liquification terminal, where the gas is cooled, LNG-ships for transportation and a regasification terminal at the destination, where it will be reheated and turned into gas. The regasification terminals are usually connected with a distribution network of pipelines.

LNG

The costs of LNG treatment and transportation have fallen in recent years, making LNG a more competitive means of distribution. Several receiving terminals exist both in Europe and in the United States, allowing gas import from other continents such as Africa.

The risk of freighting gas as LNG are not clear, some claim that since the gas is cooled rather than compressed, the gas would vaporize and burn slowly, and not explode. There has been no serious accident involving LNG since long distance transportation started in the 1960s.
