Renewable natural gas

The project at a glance

Transforming biogas from a landfill into renewable energy

The goal of the GNR Neuville project is to purify biogas from a landfill site in Neuville, Quebec, and transform it into renewable natural gas (RNG). This RNG has all the necessary characteristics to be injected into the provincial gas network, where it can replace fossil-based natural gas.

This biogas recovery process not only helps to reduce greenhouse gas (GHG) emissions by replacing fossil energy with green energy, but also allows for the local production of a renewable energy source.

Why this project?

Beyond the production of RNG, the project offers several concrete benefits.

Biogas upgrading

Instead of simply being flared, the biogas is captured and transformed into RNG, a useful renewable energy.

Odor reduction

By removing certain compounds responsible for odors, the process helps to improve ambient air quality.

GHG reduction

By replacing some of the fossil natural gas with RNG, the project helps to reduce greenhouse gas emissions.

Energy transition

The project contributes to the development of renewable natural gas in Quebec and to the transition to cleaner energy sources.

How does it work?

The main steps in producing RNG

The collection

Biogas capture

Biogas is captured at the landfill site using a network of wells and pipes. It is then drawn into the collection network using blowers.

The treatment

Biogas purification

Once transported to the plant, the biogas is cleaned and purified to remove CO2, oxygen, nitrogen, and various contaminants. This produces a renewable natural gas with the characteristics necessary for its injection into the gas network.

Liquefaction

Gas cooling

The RNG is then cooled to a liquid state. It then becomes liquefied renewable natural gas (RNG-L), which is loaded into a truck and transported to the Énergir injection station.
