Is Propane a Fossil Fuel? Here’s What to Know

Propane is produced as a byproduct of crude oil and natural gas. Is Propane a fossil fuel? It is a fossil fuel because it contains carbon from organic matter exposed to high temperatures in the Earth’s crust.

Propane separates during the petroleum refining process. At that time, propane was considered a byproduct, not a fossil fuel derivative. However, all fossil fuels have similar chemical properties. They react similarly for propulsion and heating purposes.

Even though propane is a fossil fuel, there are a few things to consider before saying “no.” Propane, known as liquefied petroleum gas (LPG or LP gas), is a byproduct of natural gas processing and, on rare occasions, crude oil refining.

What Are Common Uses of Propane?

Cooking with Propane

Propane is a prevalent fuel. It is a colorless gas used in homes as a heating source. Propane flows into homes and buildings from a large tank. Propane is also supplied in cylinders, making it portable for grills and generators.

Propane is often preferred to other fossil fuels because it burns cleaner and has a high energy content. This makes it safe for use in the home, on the job site, and even for cooking. It does not require extraction from tar pits or shale gas mining.

Shale gas extraction has risen over the past few decades. Domestic natural gas processing is now the primary source of propane for the United States. It’s a lot more money to buy propane than natural gas. Its energy efficiency may reassure some homeowners, but this isn’t always the case. The answer lies in the price of natural gas right now.

It is odorless, like natural gas, so an odor is added during processing so people can recognize its existence. Some modified automobiles and trucks may run on propane. This results in 30%-90% lower carbon monoxide emissions than regular automotive gasoline.

Propane is a good alternative for individuals who do not have access to natural gas. This is true, especially in rural areas without a connection to a large-scale natural gas pipeline network.

Residential use of propane includes:

  • Furnaces
  • Fireplaces
  • Water heating
  • Cooking
  • Dryers
  • Fire pits
  • Barbecues
  • Pool heaters
  • Camping equipment
  • Landscaping equipment
  • Backup power sources

Homeowners need to schedule propane deliveries for their outdoor storage tanks. There is no central underground delivery system for propane.

If a homeowner owns their tank, it may sit underground to eliminate it as an eyesore. 

Commercial use of propane includes:

  • Generators
  • Forklifts
  • Heavy equipment
  • Heaters
  • Outdoor lighting
  • Restaurant stoves
  • Crop dryers
  • Farm irrigation machinery
  • Fleet vehicles. 

Propane is also used in recreational vehicles and by campers who enjoy meeting challenges that require them to go off the grid.

Propane has a greater energy-to-weight ratio than gasoline or diesel. Therefore, it can provide power for many applications. These fuels are easy to transport for use in various applications.

Propane burns cleanly, creating little to no smoke and barely any soot. It has a higher energy content than natural gas, making it more efficient for heating. Propane is a liquid stored under pressure, which makes it easily transportable.

Propane will turn into gas if the pressure is released. It is safe because it will dissipate if it leaks, so there is no possibility of an explosion. It also does not pool the way gasoline or natural gas can.

Propane is popular with chefs because it provides immediate heat and maintains consistent temperatures throughout the cooking process. Propane has a high heat content and can fry and cook food quickly and efficiently.

Propane is typically associated with professional cooking because chefs can use it to produce high heat levels without changing the temperature drastically.

Globally, millions of vehicles use propane fuel. Propane is a common choice for fleet vehicles due to its environmentally friendly emissions profile. Propane contains less carbon monoxide, nitrogen oxide, and carbon dioxide than gasoline. 

Farmers use propane because it is a stable fuel that stores well year-round. It is a clean fuel that does not clog equipment engines with residue. Because propane is non-toxic, farmers are not required to create an EPA spill prevention procedure. 

Propane is a fossil fuel used as an alternative for furnaces or heaters that use electricity or gasoline/diesel fuel. Manufacturers of large engines recommend propane because it delivers excellent performance with less maintenance than fuels like gasoline or diesel.

Propane leaves no carbon deposits that cause the wearing of pistons and spark plugs. The engine stays clean and free of sludge.

How Is Propane Different Than Natural Gas?

Natural gas is extracted from the ground and is combined with crude oil to become a usable energy source. Petroleum is a byproduct of this combination process.

Both natural gas and propane are fossil fuels, though separated during the petroleum refining process.

Natural gas is formed from prolonged exposure of organic matter, like plant remains or animal carcasses, to high amounts of heat and pressure in the Earth’s crust over hundreds of millions of years.

Natural gas is a fossil fuel because it contains carbon from the organic matter in the Earth’s crust. Propane is a fossil fuel as well because it forms from natural gas. Propane is a natural gas called “bottled” or “liquefied petroleum.”

Individuals who choose to use propane are typically attracted by the significantly lower cost of propane compared to natural gas.

Because propane doesn’t move through pipelines, it must move from production facilities on trucks, railcars, and barges. This process can lead to an increase in the overall cost of propane when compared with natural gas.

What Are Fossil Fuels?

Fossil fuels like coal, natural gas, and petroleum power almost everything we do, from heating homes to fueling our cars. We use them to create electricity for household and commercial appliances.

Fossil fuels are naturally occurring gases and liquids created from organic matter millions of years ago. The most common fossil fuels are coal, petroleum, and natural gas. 

Fossil fuels have powered many things throughout history. For example, coal-powered trains in the 19th century. In the 20th century, petroleum-burning cars became popular and continue to be a significant source of energy today. 

Fossil fuels are not renewable resources because it takes very long periods to form in the Earth’s crust. Most fossil fuels that we use today come from the remains of aquatic organisms and land vegetation. 

Fossil fuels contain carbon, hydrogen, and oxygen. Coal has the least carbon per unit volume with trace amounts of sulfur.

Petroleum has very high hydrogen and carbon concentrations and small amounts of sulfur. Natural gas is mostly methane, an extremely combustible greenhouse gas that contributes to climate change.

Due to their composition, most fossil fuels produce large amounts of carbon dioxide when they burn. 

How Are Fossil Fuels Formed?

Fossil fuels form through natural processes which take millions of years. Fossil fuels are created when dead plant and animal matter become trapped under the Earth’s surface. 

This decaying process forms pockets of methane gas, also known as “natural gas,” the main component of fossil fuels. Oil and petroleum seep through layers of rock and sand until they reach porous rocks like limestone. Petroleum comes from microorganisms fermenting dead organic matter.

Natural gas forms when plant matter and animal remains are buried deep in an underground rock formation until high temperature and pressure decompose them into hydrocarbons (methane, propane, etc.).

Propane and butane are produced from refining crude oil separated during the petroleum refining process. Propane is sometimes made synthetically from other fossil fuels.

All are nonrenewable because it takes many years to regenerate (for example, oil that has been seeping through the ground for many years).

Most scientists agree that once all of Earth’s fossil fuels deplete, humans will experience an energy crisis as the world turns to alternative energy sources.

How Are Fossil Fuels Extracted From the Earth?

Fossil fuel extraction involves drilling deep into the ground.

The Earth contains natural pockets of fuel, called “reservoirs,” which are punctured to extract oil and gas. This process happens through wells that run hundreds or thousands of feet underground.

Typically, gas pressure pushes up against the weight of the reservoir rocks above it, forcing up a fountain of oil, gas, and water. The natural gas collects in large tanks for transport to consumers.

Large-scale extraction can also come from strip mining or mountaintop removal, which uses bulldozers to dig up everything on the surface. These methods are not environmentally friendly because they destroy the land and release dangerous chemicals into the air.

Coal is extracted from the ground by large electric shovels that load it into a conveyer belt to transport it to a power plant. This process is done either at the surface or in deep underground mines.

Oil rigs extract petroleum. These rigs drill a hole into the Earth, creating an oil well. Oil passes up through steel pipes where engineers can refine it.

Natural gas extraction works in much the same way as petroleum. The only difference is the rigs and wells collect natural gas, not oil.

Fossil fuels are used as fuel and contain carbon atoms. They can either be created from the remains of decomposed plants and animals or be synthetic.

Today, fossil fuels satisfy the majority of energy needs in the world. Fossil fuels generate electricity and heat, power vehicles, and are essential to everyday life

There are three main types of fossil fuel users: retailers, manufacturers, and consumers.  Propane retailers purchase the fuel from oil companies. They redistribute propane to various locations in bulk quantities. Some retailers also offer home delivery services for customers who do not own a tank or supply line.

Manufacturers are the second type of fossil fuel user. They use oil, natural gas, or coal to make many different products. For example, oil is used to make plastic and gasoline. Natural gas is used to heat homes and provide cooking stoves. Coal is used to produce electricity, power factories, make paper, refine steel for cars, and provide fuel for steel furnaces.

Consumers are the third type of fossil fuels users. They use oil, natural gas, coal, and propane to power vehicles or run home appliances like stoves and heating systems.

Fossil fuels create heat and electricity for both commercial and domestic use. Fossil fuels like propane, natural gas, and oil fuel cars provide up to 90 percent of transportation fuel worldwide. Natural gas combines with petroleum or other hydrocarbons to power vehicles running on compressed natural gas or liquefied petroleum gas. 

Manufacturing requires large amounts of fossil fuels. For example, oil refines into gasoline and propane, which is necessary to produce new plastics, paints, fuel additives, synthetic rubber, pesticides, fertilizers, explosives, and fibers like nylon or polyester.

Fossil fuels are ubiquitous because they are relatively cheap, efficient energy sources. However, fossil fuels are nonrenewable resources that have dangerous effects on the environment.

One example is global warming caused by greenhouse gas emissions from burning fossil fuels. Propane produces less carbon dioxide than gasoline when used for transportation or heating. It can be made from natural gas, biomass material, biogas, petroleum products, and coal by fractional distillation.

Is Propane a Fossil Fuel?

Propane is the cleanest burning fossil fuel available today. It’s more efficient to use and offer great value to both consumers and businesses. By using propane, home owners and business owners can do their part in reducing energy spent and pollution emitted. On top of all this, it also makes for a very portable cooking method with all sorts of uses… just another one of the many benefits of this amazing fossil fuel!
