We’re evolving B.C.’s energy landscape for a cleaner tomorrow. Behind every project at FortisBC are the teams of people involved to make it happen. Renewable Natural Gas¹ (RNG), a low-carbon² gas produced from decomposing organic waste, is one of the ways we are reducing the use of fossil fuels and greenhouse gas emissions today.

We sat down with Mason Lau, senior engineer, renewable gas, to learn more about what drew him to FortisBC in the first place, the future of RNG and his favourite animal. Spoiler alert: it helps make RNG.

“I was drawn to work at FortisBC because they are a pioneer in this space,” says Mason Lau. “FortisBC was one of the first utilities in North America to offer a Renewable Natural Gas program for their customers. I thought it was super cool to be able to use my engineering skills to try and solve some problems for climate change and make a difference for customers.”

RNG started as a small pilot program in 2009 and is now helping us progress towards our 2050 vision to replace 75 per cent of the natural gas running through our system with renewable and low-carbon gases.³

The fuel the gas system delivers today needs to change significantly toward low-carbon alternatives as we continue the energy transition. B.C. is unique because it has significant potential to produce renewable and low-carbon gases that will help the province transition to a low-carbon future.

Mason says, “One of my proudest accomplishments in my role at FortisBC has been taking the Renewable Natural Gas program from a small initiative and really building in some rigour and making it really robust, and able to be relied upon and produce this resilient energy that Renewable Natural Gas is.” To date, more than 12,500 customers have signed up to use RNG.

I think the thing that excites me the most about my job is knowing that Renewable Natural Gas will be a very established part of our energy future.

We’re working hard to expand our supply of RNG and thanks to people like Mason, we’re able to make real progress toward a cleaner future. Mason finishes by saying “If there is one thing I want people to know about what I do at FortisBC, it’s that this is real, this is really happening and there’s more of it to come, so get ready.”

¹ Renewable Natural Gas (also called RNG or biomethane) is produced in a different manner than conventional natural gas. It is derived from biogas, which is produced from decomposing organic waste from landfills, agricultural waste and wastewater from treatment facilities. The biogas is captured and cleaned to create Renewable Natural Gas.

² When compared to the lifecycle carbon intensity of conventional natural gas. The burner tip emission factor of FortisBC’s current Renewable Natural Gas (also called RNG or biomethane) portfolio is 0.29 grams of carbon dioxide equivalent per megajoule of energy (gCO₂e/MJ). FortisBC’s current RNG portfolio lifecycle emissions are -22 gCO₂e/MJ. This is below B.C.’s low carbon threshold for lifecycle carbon intensity of 36.4 gCO₂e/MJ as set out in the 2021 B.C. Hydrogen Strategy.

³ FortisBC uses the term renewable and low-carbon gas to refer collectively to the low-carbon gases or fuels that the utility can acquire under the Greenhouse Gas Reduction (Clean Energy) Regulation, which are: Renewable Natural Gas (also called RNG or biomethane), hydrogen, synthesis gas (from wood waste) and lignin. FortisBC’s renewable and low-carbon gas portfolio currently includes only Renewable Natural Gas. Other gases and fuels may be added to the program over time. Depending on their source, all of these gases have differing levels of lifecycle carbon intensity. However, all of these gases are low carbon when compared to the lifecycle carbon intensity of conventional natural gas. The current burner tip emission factor of RNG is 0.29 grams of carbon dioxide equivalent per megajoule of energy (gCO₂e/MJ) and the current renewable and low-carbon gas portfolio lifecycle emissions are -22 gCO₂e/MJ. This is below B.C.’s carbon intensity threshold for low-carbon gases of 36.4 gCO₂e/MJ set out in the 2021 B.C. Hydrogen Strategy.
