When used for heating or cooking, most people cannot tell much difference between propane and natural gas. Some barbecue enthusiasts prefer natural gas because it is a cleaner burning fuel, meaning that it doesn’t release as many pollutants into the air. Exhaust from propane might affect the taste of food, but this is also considered to be part of the charm of grilling.
Think about the environmental impact of propane and natural gas.
While they have many similarities, they also differ, including their chemical composition, energy efficiency and storage and distribution methods. Below are the main factors that distinguish propane and natural gas so you can make the right choice for your home, business or industrial use. Since prices vary from region to region, there’s no universal answer for which fuel is more economical. It’s easy to compare prices for your particular area but remember that propane delivers much higher efficiency. Ultimately, both types of fuel are more efficient and less expensive than electricity in many regions. Many appliances are perfectly capable of burning both natural gas and propane.
The Differences Between Propane and Natural Gas
A relative newcomer in the arena of household fuels, propane is much younger. We’ve only been using it for the past century or so, and it’s still rare in homes when compared to natural gas. While aboveground tanks are more affordable and quicker to install, they may not fit so well with your landscaping.
What are the disadvantages of LPG heating?
- The natural gas price is typically lower than the price of LPG, which means LPG is only really suitable for off-grid homes.
- LPG is still a fossil fuel and releases carbon dioxide when it's used to power a gas boiler.
- LPG is not as convenient as natural gas as it has to be delivered by road.
Safety and Environmental Impact
Propane, on the other hand, is compressed into a liquid state before being delivered and is stored outside the house in a propane tank. It will remain in it’s liquid state until it is converted to a gas and is used for heating. Hence, natural gas is cheaper per unit of energy than propane. However, propane has a higher energy content per cubic foot, with approximately 2,500 British Thermal Units (BTUs) per cubic foot.
- Storage and TransportPropane is stored in tanks, which can be easily transported to your property.
- Clean renewable power is now the cheapest form of power in most parts of the world – and it is getting cheaper every year.
- The GWP measures how much worse a gas is in trapping heat compared to carbon dioxide.
- Natural gas is a fossil fuel that releases CO2 through combustion.
- As a result, the mining industry often refers to propane and butane as natural gas liquids (NGLs) because they are found alongside methane.
- Another common thing between the two is that the LPG comes from natural gas processing.
Propane is stored in lightweight pressurized tanks made of steel and other corrosion-resistant materials that vary in size based on application. Tank sizes range between 100 to 1,000 gallons for residential tanks and 1,000 to 30,000 gallons for commercial and residential tanks, which can be under or above ground. These tanks have a pressure valve that releases the pressure and converts propane back into its gaseous state to facilitate residential, commercial and industrial uses. One of the most profound differences between propane and natural gas is their transportation and storage methods, which are determined by their natural state. Natural gas is a combustible, colorless, odorless and nonrenewable gaseous fossil fuel. Like propane, odorants are added to help with gas leak detection.
Why did Australia stop using LPG?
A big part of why LPG cars and bowsers are becoming less common actually comes from the death of Australia's local car manufacturing industry. Ford was making LPG-fitted Falcons from the factory until its local production ceased in 2016, while Holden stopped offering the option of LPG on its Commodore range in 2015.
Instead, you’ll use fuel from a tank or a portable canister in your home. You can choose the size based on your needs, with options ranging from a 30-gallon propane tank to a 250-gallon propane tank and beyond. Some suppliers add sulfuric scents to these products to make it easier to tell when there’s a leak. In natural gas lines, leaks can be hard to spot, and various bureaucratic and infrastructure issues can make them hard to fix as well.

While it’s not quite to the same extent, Australia’s exports of LPG have also doubled in recent years. Additional space in the trunk of a car or the bed of a pickup truck is used to store the CNG tanks. This problem has been mitigated in factory-built CNG vehicles by installing the tanks under the vehicle body, e.g. Fiat Multipla, Fiat Panda, Volkswagen Touran Ecofuel, Volkswagen Caddy Ecofuel, and Chevvy Taxi.
- One difference in the physical properties of propane and natural gas is how easily they liquefy and are transported.
- Its low carbon footprint and greenhouse gas emissions also appeal to many homeowners.
- In Australia, natural gas accounts for about 22 per cent of the country’s primary energy consumption.
- Natural gas is extracted from subsurface formations and refined into usable fuel, which is then supplied to homes and businesses via underground service lines.
- Fortunately, these emissions remain to be significantly lower than those produced by burning coal and petroleum products.
- Whether you need to power up an outdoor gas grill or get more off-grid independence in the case of a utility outage, propane is the way to go.
It’s important to consider your existing space and infrastructure, heating needs, and budget when choosing between these two fuels. Although both propane and natural gas are popular choices, LPG is more versatile. It’s a clear winner for fuel efficiency, and generally better for the environment.
A fuel’s energy efficiency dictates how much of it you’ll use. The more efficient the fuel is, the slower you’ll use it and the less you’ll have to buy. Lighter than propane, natural gas dissipates more quickly than propane when released into the atmosphere. So, you could make a claim that natural gas is a little safer than propane which takes a little longer to vanish in the air. I’ve seen a lot of cooktops, some rated to be used with LPG (liquid gas or propane) and others with natural gas.
While propane is usually measured in gallons (or liters), natural gas is found in cubic feet (or cubic meters). Heat is measured in British Thermal Units (BTUs), which is the amount of heat needed to increase the temperature of 1 pound (0.5 kg) of water by 1°F (0.56°C). When the amount of energy each produces is compared, both are measured in their gaseous form. Recently, there lpg vs natural gas has been a growing emphasis on renewable energy sources, but natural gas and propane remain crucial transitional fuels. Innovations in carbon capture and storage (CCS) technology are being developed to mitigate the environmental impact of natural gas extraction and usage.
Is LPG better than natural gas for the Environment?
LPG Advantages
It's not toxic and it does not damage the environment before or after combustion. Natural gas, on the other hand, is considered a clean-burning fuel (as it is cleaner than coal or gas), but it contains methane—a greenhouse gas that contributes to pollution.
