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-quality natural gas—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 in North America 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.

Since January 2024, Enbridge has operated six U.S. landfill gas-to-RNG facilities. Tomorrow RNG, an Enbridge company, now delivers RNG from landfills in Texas and Arkansas, collecting gas produced by waste decomposing 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 with the first project under construction in Longview, WA.

Enbridge’s gas utility, Enbridge Gas, is currently operating eight Canadian RNG projects, with four additional projects under construction.

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, Walker Industries and Comcor Environmental has constructed and commissioned a large landfill gas to RNG facility in Niagara Falls.

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.
