Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4) that has been converted to liquid form for ease of storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state. It is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately −162 °C (−260 °F); maximum transport pressure is set at around 25 kPa (4 psi).
LNG achieves a higher reduction in volume than compressed natural gas (CNG) so that the (volumetric) energy density of LNG is 2.4 times greater than that of CNG or 60 percent that of diesel fuel. This makes LNG cost efficient to transport over long distances where pipelines do not exist. Specially designed cryogenic sea vessels (LNG carriers) or cryogenic road tankers are used for its transport. LNG is principally used for transporting natural gas to markets, where it is regasified and distributed as pipeline natural gas. It can be used in natural gas vehicles, although it is more common to design vehicles to use compressed natural gas. Its relatively high cost of production and the need to store it in expensive cryogenic tanks have hindered widespread commercial use. Despite these drawbacks, on energy basis LNG production is expected to hit 10% of the global crude production by 2020.(see LNG Trade)

A second, a minute, an hour, a day goes by
I'm hopin' just to be by your side
I'm turnin' the handle, it won't open
Don't make me wait 'cause right now I need your smile
Knock, knock
When life had locked me out I turned to you
So open the door
'Cause you're all I need right now, it's true
Nothin' works like you
Little louder, little louder
Little louder knockin'
Little louder, little louder
A warm bath, a good laugh, an old song that you know by heart
I've tried it but they all leave me cold
So now I'm here waitin' to see you
My remedy for all that's been hurtin' me
Knock, knock
When life had locked me out I turned to you
So open the door
'Cause you're all I need right now, it's true
Nothin' works like you
You seem to know the way
To turn my frown upside down
You always know what to say
To make me feel like everything's okay
Little louder, little louder
Little louder knockin'
Little louder, little louder
Little louder knockin'
Little louder, little louder
Little louder knockin'
Little louder, little louder
When life had locked me out I turned to you
And you open the door
And you're all I need right now, it's true
Nothin' works like you
When life had knocked me down I turned to you
And you open the door
And you're all I need right now, it's true
Nothin' works like you
Nothin' works like you
When life had locked me out I turned to you
And you open the door
And you're all I need right now, it's true
Nothin' works like you
