Propane tanks store liquid propane under pressure
Propane is a flammable hydrocarbon gas that is converted into liquid propane gas through pressurisation in a propane tank. Propane tanks store liquid propane under pressure. This is because propane gas is put under pressure when stored in a tank, and in this pressurised state, it turns into a liquid. Propane tanks are the preferred storage method for liquid propane gas.
The pressure inside a propane tank will usually fluctuate based on the outside temperature. For example, a 20-pound propane tank at 70°F will have a pressure of 145 psi, while the same tank on a 100-degree day will have 172 psi of pressure. Propane pressure should ideally be between 100 and 200 psi to ensure the liquid propane gas remains in a liquid state.
Excessive pressure can cause the tank's safety relief valve to discharge. Direct sunlight, dark paint colours, and external heat sources can all contribute to excessive temperatures. Therefore, it is recommended to store propane tanks in a shaded and well-ventilated area.
Propane tanks are commonly used to store liquid propane for fuel in heating, cooking, hot water, and vehicles. Propane is also used in transportation fuel, typically called Autogas.

Propane is used for cooking, heating, and vehicles
Propane is a versatile fuel that is used for cooking, heating, and fuelling vehicles. It is a fossil fuel derived from natural gas and petroleum deposits. In its purest form, propane is non-toxic and odourless, but during processing, it is infused with a strong odour similar to rotten eggs to help users detect a gas leak.
Cooking
Propane is a popular choice for cooking, especially in rural areas, as it is easier to obtain than natural gas or electricity. It is used in the food service industry to fuel grills and industrial ovens, as it saves money and has a higher energy output. Many rural homes are equipped with propane cooking facilities, and it can also be used for camping or emergencies. Propane stoves and grills are available in various sizes, from small and portable to full-size cooktops.
Heating
Propane is widely used for home and water heating. It is delivered in liquid form and vaporises to supply heating appliances as a gas. Propane heating is efficient, versatile, and available in areas not serviced by natural gas lines. It has a greater BTU rating than natural gas, providing higher heat per unit. Propane can also power other appliances such as stoves, clothes dryers, and generators.
Vehicles
Propane, also known as autogas or auto propane, is used as a fuel for vehicles worldwide. It is a mixture of propane and butane and is considered a ""green" fuel as it reduces CO2 exhaust emissions by around 15% compared to petrol. It is commonly used in countries like Turkey, Russia, South Korea, Poland, and Ukraine, and in Canada, it is the most popular alternative fuel. Converting a vehicle to propane can be more cost-effective than converting it to natural gas.

Propane is more expensive than natural gas
Propane is a flammable hydrocarbon gas that is converted into liquid propane gas through pressurization in a propane tank. It is commonly used for fuel in heating, cooking, hot water, and vehicles. Propane tanks need to be periodically refilled, requiring diligent monitoring and scheduling. Propane is more expensive per unit than natural gas. For example, if propane costs $2.50 per gallon, natural gas is the cheaper option. Propane has a higher energy content per unit, making appliances that use propane more efficient. Propane delivers more BTUs for your dollars, so if you prefer using it in your home, it may be a smart choice despite the higher cost.
Propane is ideal for homes in rural or off-grid areas, as it doesn't require pipeline infrastructure. It is stored in tanks on your property, ensuring availability even if external supplies are disrupted. Propane is also more portable than natural gas, giving you the freedom to set up a barbecue anywhere in your yard.
Natural gas is generally more convenient in urban areas, where pipeline infrastructure already exists. It is delivered automatically to your home, whereas propane tanks need to be refilled periodically. Natural gas is also lighter than propane, so it dissipates more quickly when released into the atmosphere, making it slightly safer.
When deciding between propane and natural gas, consider energy efficiency, price, and convenience. While propane is more expensive and may be less convenient due to the need for tank refills, it offers higher energy efficiency and is ideal for rural homes or those without nearby gas transmission lines.
