Difference Between Natural Gas and Propane Gas


Main Difference

The main difference between Natural Gas and Propane Gas is that Natural Gas is a mixture of many gases like methane, ethane, butane, and propane, whereas Propane Gas is the raw condition of gas, which is the extract of natural gas.

Natural Gas vs. Propane Gas

Natural gas uses for heating purposes and as a fuel, and propane gas is the gas used for heating purposes and home appliances. Natural gas consists of many gases like ethane, methane, propane, and butane, while propane gas is the type of raw gas isolated by the processing of natural gas. Natural gas supply needs a pipeline because it exists in the gaseous form, whereas propane gas compressed in the liquid form so it can supply in portable containers.


The natural gas processed as liquefied natural gas (LNG), compressed natural gas (CNG), and gaseous form general natural gas; on the other hand, propane gas stored in liquid form and used in vehicles as liquefied petroleum gas (LPG). Natural gas used after a simple refinery procedure, and it becomes clear with a simple method, while propane gas needs a refinery process to become isolated.

Natural gas considered more cost-effective than propane due to its simple refinery procedures and supplying methods — propane gas considered an expensive source of energy than natural gas. The price can depend upon the area and demand.

Natural gas is clean burning and greenhouse gas that emits a less amount of harmful agents like carbon mono oxide, carbon dioxide, and nitrous oxide. Propane gas is also an environment-friendly and green gas; it is a non-toxic, safe, and cleanly burning gas. Natural gas is lighter in weight, and propane gas possesses a higher weight. Natural gas shows less energy efficiency, whereas propane gas is more energy efficient.

What is Natural Gas?

Natural gas is a mixture of different gases. It is the type of fossil fuel that distilled from the earth. It mainly composed of methane gas, but a little number of other gases like ethane, butane, propane, carbon dioxide, helium, and nitrogen also added with it making its natural gas. Natural gas is non-renewable and clear gas. Natural gas is clean-burning gas and used in home appliances.


Natural gas can be compressed and store in the liquid form. It is a naturally extracted gas and can refine through very simple methods. The cleaning process used to make it more efficient. Natural Gas can store in the refillable tanks in the liquid form. The natural gas stored in the form of liquefied natural gas is called LNG. The compressed natural gas called CNG, while the unpressurized and uncompressed is known as simple natural gas. The pipeline method used for the supply of natural gas.

Natural gas is a cost-effective and cheaper source of energy for customers. The connection cost of natural gas pipelines varies from home to home and area to area. The cost will increase if your home is farther from the main connection. The energy consumption can display as the 1000 BTU furnace uses 97 cubic feet of natural gas in one hour.

Natural gas has a safe impact on the environment. It is clean and clear, burning greenhouse gas. It emits a lower amount of harmful gases like carbon dioxide, nitrous oxide, etc. Natural gas possesses no smell and no color.

What is Propane Gas?

Propane gas is a gas pulled out from the petroleum and crude oil, and mixture of gases during the refinery process. The result of fuel can store in containers and cylinders under pressure. It becomes a highly concentrated fuel with high output. Propane gas proved useful in areas where the natural gas is not available like villages and peripheral areas. Propane gas is commonly available in the liquefied petroleum gas LPG and stored in liquefied form.

Propane gas is a hydrocarbon and fossil fuel that used 95% in the United States and North America. Propane gas is the non-toxic and green gas and causes no harm to an environment. Propane gas is colorless and odorless, so it could not detect during leakage. The detection of leakage is possible by adding odor during the processing of gas. Propane gas also used in some special vehicles as fuel, and it produces less carbon mono oxide.

Propane gas is heavier in weight than air and natural gas. It can disappear in the air very easily. Propane gas is more costly than natural gas. The leakage of propane gas can create the danger of explosion or suffocation. The propane gas leakage can be covered easily by shutting down the supply of gas by shutting down the turn off the valve at the cylinder top.

Propane gas burns in 1000 BTU furnace approximately 40 cubic feet/ hour. Propane gas can use in home appliances like heaters, kitchen tops, cloth dryers, and barbecues. It is portable gas fuel so more accessible for a barbecue at any place.

Key Differences

  1. Natural gas comprises methane gas with a small quantity of some other gases like nitrogen, helium, propane, and butane; on the other hand, propane gas is raw gas distilled from natural gas.
  2. Natural gas is a cost-effective and cheaper source of energy; contra wise propane gas is a little expensive.
  3. Natural gas supplied through a pipeline, while propane gas supplied in tanks and cylinders.
  4. Natural gas consumption is 1000 BTU furnace of natural gas uses 97 cubic feet/ hour; conversely’ for propane gas is 1000 BTU of propane uses 40 cubic feet/hour.
  5. Natural gas is lighter in weight; contrarily, propane gas is heavier in weight.
  6. Natural gas possesses less efficient energy; on the flip side, propane gas possesses more efficient energy.
  7. Natural gas has no harmful impact on the environment, safe and clean-burning gas, whereas propane gas is also ecofriendly, safe, and green gas.
  8. Natural gas can store in both gaseous and liquid form, while propane gas stores in liquid form.


Natural Gas is the mixture of multiple gases like methane, ethane, butane, propane, nitrogen, and carbon dioxide, whereas Propane Gas is the raw gas that extracts from the crude oil during the refinery process.
