Compressed natural gas

A solution for reducing the transportation sector's environmental footprint

The transportation sector accounts for 43% of all greenhouse gas (GHG) emissions in Quebec*. As such, to fight climate change, it is urgent to reduce the carbon footprint not only of our cars, but also of light, medium and heavy vehicles. Énergir now offers compressed natural gas (CNG) as an alternative to diesel for road transportation, specifically for passenger and freight transportation. CNG emits up to 25% less GHG than diesel.

About LNG

CNG has exactly the same properties as natural gas in its gaseous state. However, it can be stored at 300 times atmospheric pressure, which reduces the volume by an equal amount. Transported in high pressure tanks, it is the ideal choice for short-range daily trips.

Supply dynamics

To fuel vehicles with CNG, the natural gas from Énergir's gas network is first compressed to occupy 300 times less space than diesel or gasoline. The CNG is then stored in high pressure tanks at fueling stations along the Blue Road. There are currently 18 fueling stations supplying CNG for light, medium and heavy vehicles on short-range daily trips, providing up to 1,000 km of travel per full tank.

The Blue Road, a growing network of resorts

Introduced in 2011, the Blue Road is the first public network of compressed and liquefied natural gas refueling stations for Canada's transportation industry. Some of the stations are located along the corridor of highways A-20/H-401, between Quebec City and Toronto. As deployment of the Blue Road continues, compressed or liquefied natural gas fueling points will be added in a strategic, flexible manner at various Quebec and Ontario locations.

CNG is used in a number of sectors

Compressed natural gas meets several categories of need including waste collection, passenger transportation (long distance, inter-city) and freight transportation. 


Living with natural gas means choosing comfort and the pleasure of home living

Efficient, practical and safe, natural gas is the energy choice of many a Québec family. From air and water heating to cooking and drying, using natural gas makes living spaces even more pleasant.


Natural gas is commonly used to heat large spaces in hospitals , schools , warehouses , office buildings , arenas, and stores , as well as smaller spaces like restaurants , convenience stores and hair salons . It is also used for heating water , cooking and as fuel for commercial fleets .

The use of natural gas is also widespread in the industrial sector

Énergir's clientele includes aluminum plants and businesses in the mining, papermaking, agrifood and metallurgy sectors, all of which consume nearly half of the company's natural gas deliveries. Since natural gas is the only energy source with a high enough calorific value to replace heavy fuel oil, industries use it not only to heat air and water, but also for processing methods .

Clean and economical energy

Less costly than electricity and heavy fuel oil, natural gas can cut the energy bills of businesses and industries in half. Opting for natural gas also means choosing to reduce their greenhouse gas emissions. When a plant uses natural gas instead of oil, it cuts its greenhouse gas emissions by up to 32%, it almost completely abolished the emissions of nitrogen oxides and sulfurs (those responsible for acid rain ) as well as the fine particles and it saves up to 40% on energy costs — key to continued development and improved profitability.


Natural gas is also a fuel

Liquefied natural gas and compressed natural gas motors are a proven technology commonly used for many years in road and maritime transport worldwide. As the best alternative fuel to diesel or gasoline for heavy-duty vehicles, natural gas in transportation also reduces GHG emissions by as much as 25%.
