Storage and Use
At normal temperature and pressure, propane is a gas. It changes to a liquid when cooled and moderately pressurized – about twice the pressure in a normal truck tire.
It is stored and transported in its compressed liquid form, but by opening a valve to release propane from a pressurized storage container, it is vapourized into a gas for use. Even at -40°C (-40°F), propane still vapourizes; that is why propane can even be used at extreme freezing temperatures.
Propane is an odourless gas to which an odourant – ethyl mercaptan – has been added to help detect leaks.
Liquid propane boils to vapour at -42.2°C (-44°F).
In a liquid form, propane is half the weight of water.
One unit of liquid propane has the same energy content as 270 units in gaseous form.
About 23.5 cubic feet (0.66 m3) of air is required to burn 1 cubic foot (0.028 m3) of propane.
Complete combustion of propane produces clean water vapour and carbon dioxide.
Hundreds of thousands of Canadians rely on propane in countless applications for their homes, businesses, farms and fleets.

Propane is a clean-burning energy source that is low carbon, emits virtually no air pollutants, and is safely transported and used across Canada every day.
Compared to other fuels, propane’s utilization helps to improve air quality, reduce GHG emissions and protect the environment.
- Fuel vehicles that produce far fewer harmful emissions than traditional fuels.
- Provide heat and power to rural and remote ‘off-grid’ communities across Canada, decreasing health impacting pollutants.
- Offer farms a chemical-free way to control pests and weeds, and a cleaner way to dry crops and heat barns.
- Act as a reliable and portable back-up energy source in conjunction with renewables.
