LNG

   Natural gas currently makes up about a quarter of the world's energy supply and the demand for natural gas is expected to gorw rapidly as petroleum resources being depleted.

Natural gas is liquefied mainly for storage and transpotration purposes.  Converting natural gas into LNG reduces the volume of the gas by roughly 620:1, meaning that one ship can transport 620 times as much gas in oet trip..

LNG can be stored at a cryogenic facility, distributed (as liquid) for use as engine fuel, or transformed back into a gas and fed directly into pipelines .Liquefied natural gas (LNG) is the same gas you use to heat your home  (predominantly methane of CH4), that has been super-cooled into a liquid state at approximately -260 degrees F and at near atmospheric pressure.

Natural gas is relatively clean and can serve as an important bridge to a greener future.  In addition to dozens of marine vessel applications, there are now more then 12 million natural gas vehicles worldwide.  In 2009, over 300,000 million cubic feet of natural gas were used for vehicle fuel. 

In more than 50 years of commercial use, the natural gas industry has had an exemplary safety record.    The industry has developed systems and procedures for handling LNG that ensure public security in the unlikely event of an accident.  Consequently, there have been very few major incidents resulting from the use of LNG.  the production, storage and use of LNG is  as safe as (or safer than) that of any other commercial fuel.
