LNG – liquefied natural gas – is basically natural gas that has been super-compressed to form a liquid that can then be transported easily by specialist ships and road tankers.
It was Kirsty Taylor who caught the judges’ attention. She has won an iPad for her school Hazelhead Academy in Aberdeen. Well done!
Our next letter is M – for mud, yes mud. But what is it? A clue is that drilling rigs use it.
We want you to tell us what it is, where it comes from and how it is used in not more than 250 of your own words.
Deadline for Entries is Friday, February 25. The winning entry will be published on March 4 and its author will have won an iPad for their school, thanks to Shell’s generosity. Shell’s Inside Energy app is packed with information on energy through videos, animations and picture galleries.

L is for Liquefied Natural Gas
What is LNG?
Liquified Natural Gas, or LNG for short, is a natural gas which is usually 90% methane. It also contains small quantities of ethane, propane, butane and nitrogen. It has to be transformed into liquid form for ease of storage or for transportation purposes.
Production
The production of LNG removes all of the water and any carbon dioxide or anything else in it that could cause it to freeze. This is important because it is kept at really low temperatures. It is also crucial that the cold LNG doesn’t come into contact with water as that can cause an explosion. This process can in some cases be designed to give almost 100% methane.
What is it used for?
It is used as a substitute for conventionally produced natural gas because there is a lot of “stranded” gas in remote areas that can be liquefied and transported to market in specialist ships. It can be relatively cheap.
