Natural Gas vs. LPG — What's the Difference?
By Tayyaba Rehman & Maham Liaqat — Published on August 19, 2024
Natural Gas is primarily methane with a mix of other gases, used for heating and cooking. LPG, or Liquefied Petroleum Gas, is propane or butane, stored as a liquid under pressure.

Key Differences
Natural Gas is a mixture of hydrocarbons, mainly methane, extracted from underground or undersea deposits. It's used widely for heating, cooking, and electricity generation due to its abundance and relatively clean combustion. On the other hand, LPG, short for Liquefied Petroleum Gas, is primarily composed of propane, butane, or a mixture of the two, and is produced during natural gas processing and petroleum refining. LPG is stored in pressurized tanks and is used similarly to natural gas but is more portable due to its liquefied state.
Natural Gas, being lighter than air, disperses quickly when leaked, which can reduce its risk of ignition. LPG, however, is heavier than air and can pool at ground level, creating a greater risk of ignition if leaked.
The distribution of Natural Gas is predominantly through pipelines, making it a convenient option for residential and industrial areas connected to the gas network. LPG, in contrast, is distributed in portable cylinders or tanks, making it a versatile choice for areas without pipeline infrastructure.
Natural Gas is considered to be more cost-effective for consumers connected to a supply network due to the lower costs associated with its extraction and distribution. LPG, while more expensive, offers the advantage of portability and accessibility, especially in remote or off-grid locations where natural gas pipelines are not available.
In terms of environmental impact, both Natural Gas and LPG are cleaner alternatives to coal and oil, producing fewer pollutants and greenhouse gases upon combustion. However, Natural Gas has a slight edge in terms of environmental friendliness due to its higher methane content and more efficient combustion.
