British Columbia adopts renewable natural gas

Through its CleanBC initiative, B.C. plans to increase renewable natural gas blending to 15 per cent by 2030. Fortis photo.

Renewable natural gas (RNG) production typically begins with the collection of organic wastes such as landfill waste, agricultural waste, or waste water. When organic waste decomposes, it releases methane, which is the primary component of natural gas. Producers can capture and purify this methane and inject it as RNG into existing natural gas streams.

Since 2010, an increasing number of utilities and waste management facilities in British Columbia are producing RNG. Fortis BC, a B.C. utility that distributes natural gas, will soon be able to provide roughly 430 000 Gigajoules (GJ), or 0.2 per cent, of total B.C. natural gas end-use demand, with RNG.

Fortis customers can opt-in to pay an additional monthly charge to receive a 5 to 100 per cent blend of RNG for residential use. The household cost of RNG blending ranges from $2.35/month for 5 per cent blending, to $47.02/month for 100%.

Description: This map shows the locations of 7 RNG projects currently operating, or in development, in B.C. RNG production is primarily situated near landfill, commercial, agricultural, or other waste-related processing facilities. These sites require an anaerobic digester tank and a biogas upgrader connected to a local distribution pipeline to ensure the safe injection of RNG.

Through its CleanBC initiative, B.C. plans to increase renewable natural gas blending to 15 per cent by 2030. This will require a significant increase in production, but according to previous technical estimates, a 15 per cent blending rate is within B.C.’s potential production capacity.

One growing source of RNG is from landfill waste, which was responsible for approximately 20 per cent of Canada’s total methane emissions in 2017. By diverting waste materials away from landfills, RNG production acts as a carbon-neutral supplement to B.C.’s current natural gas supply.
