Enbridge and Renewable Natural Gas (RNG)

Renewable Natural Gas (RNG) is created by capturing “biogas” emissions from organic waste, landfills and wastewater treatment plants and upgrading into pipeline-grade methane—and it will play an important role in society’s cleaner energy future.

Following the upgrading process, carbon-neutral RNG is easily blended into existing natural gas distribution and transmission networks—where it can be used to fuel transit fleets, power industry, and heat homes and businesses without the need for any alterations, since it is an identical fuel.

Why RNG?

RNG is a carbon-neutral fuel, it can help battle climate change, and it’s all about putting waste to work.

RNG has the potential to play a key role in the decarbonization of North America’s gas supply. Long-term energy outlooks are predicting that as much as 10% of all natural gas demand could be supplied by RNG, presenting investment opportunities that are strongly aligned to Enbridge’s existing natural gas transmission and distribution assets.

So, what is Enbridge doing with RNG?

Enbridge has committed to achieving net-zero greenhouse gas (GHG) emissions from our operations by 2050. We’re working with industry partners and leveraging our vast network of gas pipelines to help pioneer RNG as an effective solution for society’s net-zero ambitions.

In November 2023, Enbridge announced the purchase of six operating U.S. landfill gas-to-RNG facilities from respected, experienced RNG developer Morrow Renewables. Tomorrow RNG, an Enbridge company, now delivers RNG from municipal landfills in Texas and Arkansas, collecting gas produced by waste decomposition in the landfill, and treating and compressing the gas to pipeline specifications.

In March 2023, Enbridge announced a collaboration with Divert Inc. to develop facilities across the United States that turn wasted food into RNG. The collaboration aims to grow RNG supply, decarbonize the food value chain and combat climate change.

Meanwhile, Enbridge’s gas utility, Enbridge Gas, is actively involved in seven Canadian RNG projects operating or under construction, with an additional 50+ projects in various stages of development.

In Toronto, one of the city’s solid waste facilities is now producing RNG around the clock as part of a collaboration with Enbridge Gas.

Meanwhile, a partnership between Enbridge Gas, Walker Industries and Comcor Environmental has broken ground on Ontario’s largest RNG facility in Niagara Falls, with an agreement to jointly develop other RNG projects across the country.

Numerous regional targets for RNG are also being announced, which further supports our strategic growth in this sector.

Enbridge will participate across the RNG value chain, from biogas collection and upgrading to pipeline-grade RNG, to injection into pipelines for transportation and distribution.
