Liquid Natural Gas (LNG) – Liquefied Natural Gas: A Reliable Methane Solution
In summary, Liquefied Natural Gas (LNG) is natural gas cooled to its liquid state (below -161°C or -258°F), reducing its volume by approximately 600 times, making it more economical and safer to store and transport when there are no pipelines.
Liquefied Natural Gas – Liquid Natural Gas (LNG) is natural gas that has been cryogenically cooled into a liquid state, below the methane boiling point of -161°C or -258°F.
It’s the same gas that powers stoves, heaters, and numerous other applications in homes and businesses around the world.
Liquid Natural Gas (LNG) is primarily composed of methane and is naturally produced.
At ELGAS, we focus on unlocking the potential of stranded gas—small, isolated gas deposits that aren’t economically viable for traditional pipelines.
Our specialization lies in micro-LNG plants (liquefied natural gas plant) that transform these stranded resources into valuable energy sources.
By leveraging cutting-edge technology developed by our parent company, Linde, we make it possible to utilize stranded gas for high-volume industrial and commercial applications.
This technology offers compelling benefits as a fuel source, including: providing cost-effective energy solutions for a wide range of applications.
Liquefied Natural Gas – Liquid Natural Gas (LNG) is a cleaner-burning fuel compared to other fossil fuels, helping reduce greenhouse gas emissions and supporting sustainable energy practices.

Liquefied Natural Gas Price – Price of LNG Gas
The liquefied natural gas price (price of LNG gas) in Australia is influenced by LNG exports.
Liquefied Natural Gas – LNG exports drive up the price of LNG gas exports and domestic pipeline natural gas use.
However, the same isn’t always true if the natural gas comes from stranded natural gas fields.
As stranded natural gas would be difficult to export, the export demand doesn’t affect it.
The liquefied natural gas price (price of LNG gas) from stranded natural gas reserves tends to be more stable and is frequently offered on multi-year contracts.
In addition, for larger commercial users, the liquefied natural gas price (price of LNG gas) is frequently less than that for LPG, providing some incentive to switch from LPG to Liquefied Natural Gas – LNG.
Liquefied Natural Gas Transportation – Liquid Natural Gas Ship – LNG Carrier: How is LNG Transported?
Define LNG carrier (LNG gas carrier) or how is liquid natural gas transported (how is LNG transported)?
Liquefied natural gas transportation is typically by ocean LNG freight in an LNG ship (liquid natural gas ship), LNG carrier ship, or LNG tanker vessel.
For LNG road transport, an LNG carrier (LNG gas carrier) is an LNG tanker truck (liquid natural gas tanker) or LNG transport trucks.
How is Liquefied Natural Gas – LNG stored? Liquid Natural Gas Tanks
An LNG storage facility has LNG storage in an LNG vessel, LNG tank (liquid natural gas tanks), or cryogenic liquid natural gas tanks.
Liquid natural gas tanks are typically vertical, as opposed to horizontal LPG tanks.
Liquified Natural Gas Meaning – LNG Meaning
Liquified natural gas meaning is natural gas that has been cooled to a liquid state, below -161°C or -258°F, making storage and transport easier and more cost effective.
Liquefied Natural Gas – LNG is the acronym that stands for liquefied natural gas.
Why Natural Gas is Liquefied at a Liquefied Natural Gas Plant
The liquification process, at a liquefied natural gas plant, reduces the volume of the natural gas by more than 600 times, making storage and transport more feasible and economical to locations without a pipeline.
This makes long distance transport possible, including transoceanic shipments by LNG ships.
Liquefied Natural Gas – LNG allows the supply of natural gas to areas that are not served by natural gas pipelines.
Summary of How LNG Works
- Raw natural gas is cleaned of impurities, any water is removed, natural gas liquids are stripped out, and then it is processed by an LNG plant.
- Dry natural gas (methane) is cooled to its liquid state, below the methane boiling point of -161°C or -258°F.
- The liquefied natural gas (LNG) can then be stored in cryogenic tanks or transported in special cryogenic trucks or ships.
- At the point of use, the LNG is warmed to convert it back into a gas, called regasification, and then used on site or distributed through a pipeline.
Regasification of Liquefied Natural Gas – LNG
At the point of use, the Liquefied Natural Gas – LNG is warmed to transform it back to its gaseous state, using an LNG vaporizer.
This process is called regasification.
Then the LNG is either used on site or transported by pipeline to distribution companies, industrial consumers, and power plants.
What is Liquefied Natural Gas – Liquid Natural Gas (LNG) Explained
What is liquefied natural gas?
Liquid Natural Gas (LNG) , or Liquefied Natural Gas, is simply natural gas (methane) in a liquid form.
Liquefied Natural Gas – Liquid Natural Gas (LNG) is natural gas cooled cryogenically to below its boiling point of −161°C.
This changes the natural gas from its gaseous state to a liquid, reducing its volume by 600:1 (1m³ of LNG = 600m³ of methane gas).
To use Liquid Natural Gas (LNG), it goes through a regasification process, transforming from a liquid back to a gas.
Liquefied Natural Gas – Liquid Natural Gas (LNG) is used just as you would pipeline natural gas.
Put simply, Liquefied Natural Gas – Liquid Natural Gas (LNG) is Natural Gas Made Portable™.
Liquefied Natural Gas – Liquid Natural Gas (LNG), which is predominantly Methane, is an odourless, non-toxic and non-corrosive.
If spilled, the Liquefied Natural Gas – Liquid Natural Gas (LNG) evaporates quickly and disperses, leaving no residue.
Benefits of Liquefied Natural Gas – Liquid Natural Gas (LNG)
- Reduced storage volume of natural gas of more than 600 times as LNG goes from its gaseous state to liquid.
- The volume reduction allows it to be transported more efficiently over long distances.
- Liquefied Natural Gas – Liquid Natural Gas (LNG) can be supplied to locations without a pipeline, including remote destinations.
- A small liquefied natural gas plant can be used to process “stranded natural gas” in gas fields to small to justify a pipeline.
