For communities that decide to go ahead with an anaerobic digestion project, the environmental benefits are two-fold: besides reducing greenhouse gas emissions from their landfill sites, the sites produce their own RNG. Similar to natural gas in its chemical make-up, RNG can be injected into the Énergir network or used as a fuel.

Growing potential

Énergir actively supports the development of biomethane by contributing its expertise to biomethane projects currently being developed. Biomethane is an energy solution that helps meet the requirement of the Québec government’s 2030 energy policy and that contributes to the transition toward a more sustainable, lower-carbon economy. Its potential is enormous: according to Énergir’s forecasts, between 700-1,000 million m3 of renewable natural gas could be produced each year in Québec.

In Saint-Hyacinthe, nothing is lost, everything is transformed

In summer 2017, Saint-Hyacinthe will be the first city to inject biomethane into the Énergir network. Each year, more than 149,300 tonnes of organic wastes will be transformed into 13 million m3 of RNG. Of this, 1 million m3 will be used to heat its municipal buildings and 12 million m3 will be injected into the natural gas network to supply other cities, institutions and private customers.

The City thus expects to achieve savings of half a million dollars a year, thereby inspiring other municipalities in Québec, some of which are planning similar initiatives in the years to come.
