Propane, or liquefied petroleum gas (LPG), is a hydrocarbon gas that is compressed and stored in a liquid form.
It is both colorless and odorless, although an odor is added for safety reasons. That way, if a leak were to occur, it could be detected.
Propane is considered a clean energy source because of its non-toxic and non-poisonous nature.
What is Propane Used For?
Propane was first used inside homes in 1912. Since then, scientific and technological advancements have led to hundreds of propane fuel uses, including:
- Furnaces or boilers
- Water heaters
- Cooking range
- Engine applications
- Outdoor grill
- Patio heater
- Spa or pool heater
- Clothes dryer
Propane used only for motor vehicles is often referred to as autogas, even though it is the same propane used for other purposes.
Is Propane a Natural Gas?
Propane is one of the cleanest, most efficient, and most versatile fuels. It is an alternative fuel source that continues to grow in popularity as it is environmentally friendly and emits lower levels of greenhouse gas emissions into the atmosphere.
Propane is a by-product of natural gas processing and crude oil refinement. It is produced from liquid components recovered during the processing and refinement of natural gas and crude oil.
A more sustainable and renewable source is also being explored, which is produced from 100% renewable raw materials. In this case, propane is produced from renewable biomass-based feedstocks. This is helpful as it has the same chemical structure and physical properties as conventional propane.
Propane is a non-toxic and safe fuel for transportation and can be shipped via pipeline, railroad, barge, truck, or tanker worldwide.
Most of the propane consumed in the United States is produced in North America. In fact, 90% of the United States propane supply is produced domestically, while the remaining supply is imported from Canada and Mexico.
Propane has several advantages over other fuel types, including its domestic availability, reliability, and reduced emissions.
Despite its widespread popularity and use, propane and its environmental effects have been misunderstood.
10 Benefits of Using Propane:
There are some distinct benefits of using propane as an energy source.
1. Non-toxic: Propane is non-toxic and non-poisonous, so it cannot contaminate soil, groundwater, marine ecosystems, or natural habitats.
2. Low carbon: Propane is a low-carbon, clean-burning energy source that does not emit air pollutants.
3. Reduce greenhouse gases: Using propane improves overall air quality, reduces greenhouse gases, and improves health outcomes.
4. Efficient: It is a dependable and efficient source of heat and power that helps lower emissions.
5. Affordable: The propane supply is high, so prices are often lower and cheaper than other energy sources.
6. Reliable: Propane is reliable, even during extreme weather or a natural disaster, providing a backup and alternative energy source.
7. Abundant resource: Propane is an abundant resource. The United States is one of the leading producers of propane and produces more propane than the current demand.
8. Alternative to gasoline: It is an attractive alternative to gasoline and diesel and is sometimes referred to as a “bridge fuel” until long-term renewable technologies are developed.
9. It’s safe: It can safely be transported globally and within the United States.
10. Benefits economy: The production of propane benefits the economy, as it employs over 97,000 workers across the United States and contributes around $40 billion to the U.S. gross domestic product.
5 Myths About Propane & the Environment:
Myth 1: Propane is bad for the environment – False
True: Propane is considered a low-carbon and clean energy source that is environmentally friendly before and after combustion.
Propane is non-toxic and non-poisonous, so it cannot contaminate soil, groundwater, marine ecosystems or natural habitats. When released into the air, propane evaporates and dissipates, producing almost no effects on the ozone layer and no air pollutants.
Even if there is an unexpected leak or spill, propane becomes a harmless vapor that requires no cleanup or remediation. For this reason, the transportation of propane is far safer than other fuels, as the environmental impact and risk associated with a spill or leak are much lower.
Myth 2: Propane is not clean energy – False
True: Propane is one of the cleanest and most versatile fuels. While it emits a low level of carbon dioxide, it is considered a clean fuel when burned compared to gas and diesel. It is listed as a clean fuel under the 1990 Clean Air Act and is not considered a greenhouse gas.
The greenhouse gas emissions from propane are lower than from gasoline, disease, coal, and heating oil.
Substituting propane for other fuels reduces the amount of carbon dioxide, carbon monoxide, and nitrogen oxide released into the atmosphere. For example, propane emits 60% less carbon monoxide than gasoline and emits almost 100% less particulate matter than diesel.
A propane grill emits 50% less carbon dioxide than a charcoal grill, 43% fewer greenhouse gases than electricity, 38% fewer greenhouse gases than fuel oil in furnaces, and 26% fewer greenhouse gases than gasoline in vehicles. This makes it an attractive alternative fuel source, as it is much cleaner.
Myth 3: Propane isn’t a safe fuel – False
True: Propane is a safe fuel when stored and handled correctly. It is non-toxic, safe to transport, and dissipates when released into the air. Thus, in the unlikely event that there is a leak or spill, unlike liquid fuels, propane will not contaminate the surrounding environment. It will vaporize and dissipate into the air, leaving behind no mess.
In addition, since propane is non-toxic, it does not cause health issues or concerns.
Myth 4: Propane is not energy efficient – False
True: Propane is considered an efficient fuel because it has a higher energy density and delivers more BTUs (per gallon or cubic foot). It also burns less volume per hour than other conventional fuels. For example, a propane vehicle’s gas tank goes much farther than most other liquid fuels. This efficiency leads to significant economic benefits.
According to the U.S. Department of Energy, electricity costs more than twice the cost of propane.
Propane is more economical and more efficient than electrical heat. A well-functioning propane heating system can reduce energy costs and reduce greenhouse gas emissions by as much as 68%.
Propane creates a warmer heat within the system, meaning that the heat coming out of the air registers is much warmer immediately. For this reason, less propane is required to generate heat to the desired temperature than conventional heating methods.
A propane heating system can reach up to 98% efficiency, which is highly helpful.
Propane cooking systems heat much quicker and efficiently than electric cooktops, reducing cooking time and energy. It also reduces static in dryers and lessens wrinkles without fabric softener.
Myth 5: Propane causes air pollution – False
True: Propane burns more cleanly than gasoline or diesel fuel. Propane vapor will not cause air pollution and is not considered an air pollutant. It does not contain sulphur and is not a contributor to acid rain. It emits zero soot and does not affect the ozone layer or contribute to smog production.
The burning of propane produces lower levels of air toxins, such as benzene and acetaldehyde, than gasoline or diesel. For example, propane vehicles reduce life-cycle greenhouse gas emissions by 10%.
The exhaust associated with a propane engine does not emit air pollution, which is one of the main reasons forklifts and other machinery are powered by propane inside warehouses across the United States.
Final Thoughts on is Propane a Natural Gas
Millions of people use propane daily for residential, commercial, and industrial purposes. While it is a popular and clean energy source, it remains misunderstood because of misinformation.
Propane is a solution that can help reduce air pollution and greenhouse gas emissions and protect the natural environment.
In addition, propane offers several benefits related to reliability, efficiency, and abundance.
Looking towards the future, as more propane is produced from renewable sources (e.g. renewable biomass-based feedstocks), it will increase the environmental benefits associated with its use. Propane is a sustainable choice that will continue to benefit future generations.
