Today, we're diving into natural gas. Can anyone tell me how it is formed?
Isn't it made from old plants and animals, like coal?
Great connection! Natural gas actually comes from marine organisms, not from plants like coal. Over millions of years, these organisms were buried under layers of sand and clay, and through heat and pressure, they transformed into hydrocarbons.
So, does that mean it takes a long time to form?
Exactly! Just like coal, the creation of natural gas is a slow process that requires specific conditions. Remember, we call such fuels 'fossil fuels' because they come from ancient life.
How do we even find it?
That's an excellent question! We extract natural gas from wells, and it's often found alongside oil in reservoirs. The process can be tricky due to its location beneath impervious rock layers.
To remember this, think of the acronym 'GAS': 'G' for 'Gas', 'A' for 'Ancient organisms', and 'S' for 'Sealed in layers'! Let's recap: natural gas forms from marine organisms under heat and pressure over millions of years.

Now that we know how natural gas is formed, what do you think its uses are?
Is it used for cooking like LPG?
Yes, absolutely! It can be used as a cooking fuel. In fact, it's quite popular in households where it is transported in the form of LPG or Compressed Natural Gas (CNG).
What about vehicles? I’ve seen CNG cars on the road.
Exactly! Natural gas is increasingly being used as a cleaner alternative for fuel in vehicles because it emits fewer pollutants compared to gasoline or diesel.
Are there any other industrial uses?
Definitely! Natural gas is used in the production of fertilizers, chemicals, and even electricity generation. It plays a crucial role in our energy landscape.
To remember its uses, think of the phrase 'CLEAN': 'C' for 'Cooking', 'L' for 'Light vehicles', 'E' for 'Electricity', 'A' for 'Agriculture', and 'N' for 'Natural gas'.
Introduction & Overview

Quick Overview
Standard
Natural gas, a vital fossil fuel formed from ancient marine organisms, is primarily used for power generation and as a cleaner alternative for transportation. It is stored as compressed natural gas (CNG) and has significant reserves in India, with various applications in industries and households, making it an essential energy resource.
Detailed
Natural Gas
Natural gas is considered a vital fossil fuel due to its ease of transport and usage. Stored under high pressure in the form of compressed natural gas (CNG), it is increasingly adopted for power generation and as a fuel for transport vehicles due to its cleaner-burning properties compared to other fossil fuels.
Formation and Reserves
Natural gas forms from the decomposed remains of ancient marine organisms that fell to the seabed and were covered with layers of sand and clay. Through millions of years of heat and pressure, these organic materials became hydrocarbons. In India, notable natural gas reserves are located in Tripura, Rajasthan, Maharashtra, and the Krishna Godavari delta.
Applications
CNG is utilized for generating electricity and is also a fuel option for vehicles, helping reduce air pollution. It can be directly supplied to homes and factories via pipelines, enhancing convenience in its use. Various chemicals and fertilizers are also produced using natural gas, underpinning its importance in multiple sectors.
Summary
In summary, natural gas stands out as an accessible, clean energy source that supports a diverse range of applications, emphasizing the importance of judiciously utilizing this exhaustible resource while considering environmental impacts.
