Renewable natural gas

An energy produced here

Transforming organic matter like table scraps into energy: a concrete solution in the fight against climate change. This renewable natural gas produced locally can be added to the gas network or used directly to heat buildings or as a fuel. It’s one big step closer to energy independence.

About biomethanation

  1. You save your table scraps.
  2. They’re collected.
  3. The plant transforms them into renewable natural gas.
  4. Renewable natural gas is added to the gas network.
  5. The energy is ready for use.

Meet our first producer: Saint-Hyacinthe

Saint-Hyacinthe was the first city in Québec to produce energy through biomethanation and move one step closer to energy independence. Implemented in partnership with Énergir, this initiative will heat municipal buildings and fuel city vehicles while reducing greenhouse gas emissions. This project will, in time, lead to an annual reduction of 25,000 tonnes of greenhouse gas. It’s a great example of a community repurposing waste to produce renewable energy.


In 2023, Québec City will inject renewable natural gas into Énergir’s network. The biomethanation center of the agglomeration of Québec (CBAQ) is currently under construction. It will treat:
  • food residues (86,600 tons/year)
  • biosolids (materials from the wastewater treatment plant) (96,000 tons/year)

Coop Agri-Énergie Warwick

Coop Agri-Énergie Warwick is the first agricultural cooperative dedicated to the production of renewable energy in Québec. It brings together roughly ten agricultural producers from the Arthabaska RCM who will produce renewable natural gas (RNG) from slurry and manure from dairy cattle mixed with residual organic matter from surrounding businesses. The biomethanation complex will be developed, built and operated by Coop Carbone, a non-profit solidarity cooperative working on the development of cooperative agricultural biomethanization projects. The start of operations is already planned for autumn 2020.

Laval University becomes the first Québec university to buy renewable natural gas

The agreement between Laval University and Énergir for the supply of renewable natural gas (GNR) supports the University's sustainable development mission and adds to its approach to reduce energy consumption and combat climate change and carbon neutrality.

A great potential for Québec

A recent study by Deloitte and WSP Canada demonstrates how much promise this renewable energy source holds for Québec’s energy transition.

Potential to accelerate the energy transition

  • Using this volume of RNG in the gas network by 2030 would eliminate 7.2 million tons of greenhouse gas (GHG) emissions each year. That’s roughly like taking 1.5 million cars off the road.1
  • GHG reductions could be even greater if RNG were to replace diesel fuel in heavy transport, since the latter accounts for 12.1% of total GHGs in Québec.2
  • All regions of Québec will have technical and economic potential for RNG production by 2030.
  • By 2030, RNG’s technical and economic potential increases because of second‑generation technologies that use forest residues in production.

A winning energy source accross the board

  • 100% renewable energy that reduces GHGs Provides new sources of revenue for different sectors (agricultural, forestry, municipalities, etc.)
  • Gives organic waste new life, supporting a circular economy
  • Creates local jobs that cannot be outsourced and economic spinoffs for rural communities
  • Improves the trade balance by decreasing energy imports
  • Can be used in the existing gas distribution system

Other forms of natural gas

There are several forms of natural gas, allowing citizens to consume better and less. Renewable to give our waste a second life, compressed or liquefied to replace diesel as a fuel, natural gas is an energy that meets a variety of needs.

  • Natural gas

    Énergir is the largest gas distributor in Québec and Vermont.
  • Liquefied natural gas

    LNG is natural gas that changes from a gaseous to a liquid state.
  • Compressed natural gas

    CNG is compressed natural gas that can be used as fuel.

Énergir, more than natural gas!

We believe diversity is key to the future of energy. This is why Énergir is involved in developing solar and wind power and hydroelectricity.
