About natural gas

Natural gas distributed in Québec is composed of 95% methane, less than 4% ethane and nitrogen, and 1% carbon dioxide and propane. To reach the user, natural gas travels through different mains buried in the ground. An intricate network lies beneath cities, connecting homes, businesses and industries.

Growing demand

The environmental benefits and competitiveness of natural gas compared to other forms of energy are contributing to its growing demand in all sectors. Prioritizing its use as a replacement of more polluting energies is a logical choice for the environment and for achieving Québec’s greenhouse gas reduction targets.

Safe energy

Natural gas is not toxic and it is odourless in its natural state. An odorizer called mercaptan is added to natural gas to make it easy to detect in the case of a leak. Mercaptan gives it that "rotten egg" smell and makes it possible to detect at concentrations of less than 1% in the air.

In the open air, natural gas rises and rapidly dissipates since it is lighter than air. It is insoluble in water and does not contaminate it. It forms bubbles, rises to the surface and quickly disperses into the air.

Natural gas does not ignite easily. To burn, it must have a 5 to 15% concentration in the air (i.e. a lower range than that of gasoline or propane) and an ignition source must be present.

Natural gas, part of everyday life

Millions of people enjoy the benefits of natural gas, which make it one of the most commonly used energy sources in the world today. From homes, restaurants and schools, to grocery stores, office buildings, hospitals and heavy industry, natural gas is part of Québecers’ day-to-day life.

A complementary solution

Where public transit is concerned, vehicle electrification is one alternative to diesel, but this solution isn’t sufficient in some cases, i.e. for transportation over long distances or on winding terrain, where CNG proves more efficient.

Passenger transportation vehicles running on CNG produce less GHG and less noise—two factors that allow for a better experience among primary users: our citizens. CNG is also more economical than diesel, which is a considerable advantage for companies managing vehicles with high fuel consumption, further exacerbated by their frequent stops.

Adapted solutions

To reduce their GHG emissions, road tractors can opt for LNG or CNG. Those with less daily mileage to cover or a lower charge to drag often choose CNG, which is better suited to short-range daily transportation. Several engine models are available to allow freight transportation companies to convert their vehicle fleet to natural gas, thereby saving money and helping improve air quality.

Impressive results

Since 2001, Énergir and many of its customers have helped carry out more than 130,000 energy efficiency projects that have helped keep more than one million tonnes of GHGs from being released into the atmosphere. That’s equivalent to 250,000 fewer cars on our roads.

Other avenues for natural gas

Natural gas is also available in other forms, including liquefied natural gas (LNG) and compressed natural gas (CNG), which can now replace diesel as a fuel for the heavy transportation and maritime transport industries. Now, businesses and establishments in remote areas not served by a pipeline network can access a natural gas supply via truck or boat. The development of organic matter also gives Québec access to vast reserves of renewable natural gas. This resource allows municipalities and other organizations to turn a profit on their wastes while reducing their environmental footprint.
