Tourmaline, Clean Energy open two new natural gas fuelling stations in Alberta
But Canada has been much slower than the U.S. when it comes to building out an RNG industry and related infrastructure. Littlefair said that's why in this country it makes sense for the transportation sector to look to natural gas as a "bridging" solution until cleaner options are available.
"It's not going to be one-size-fits-all technology — there will be places where electricity might make sense, where hydrogen might someday make sense," he said.
"But we know that natural gas will work today. We know it's going to take all of the above to be able to reduce our carbon footprint worldwide."
Tourmaline CEO Mike Rose said CNG makes sense for Western Canada in particular, because natural gas in this region is abundant, easily distributed and affordable. In just over a year, Rose said, the existing fuelling station in Edmonton has grown to count nine heavy-haul trucking companies among its customers.
Cummins, one of the world's leading engine manufacturers, recently introduced its X15N natural gas engine into the Canadian and U.S. heavy-duty truck market, a development that is expected to drive further adoption of CNG. Companies such as Walmart, UPS and FedEx have already been testing those engines within their own fleets.
"This will rapidly involve into a material new segment," Rose said. "The new engine technology is here that we need ... and we're going to scale it up."
One of North America's largest logistics companies, Mullen Group Ltd., already has 19 fully operational CNG trucks, with plans to deploy another 15 as soon as they become available.
CEO Murray Mullen said that while natural gas-powered engines are about 30 per cent more expensive than a traditional diesel engine, the CNG itself is cheaper than retail diesel fuel.
He added the natural gas-powered trucks Mullen Group already has in its fleet have been performing "exceptionally well."
"Compressed natural gas is viable, it's competitive, and it's good for the environment," Mullen said. "Are all of our trucks on it yet? No ... But we think we're in the early stages of this."
Tourmaline and Clean Energy Fuels plan to have a total of seven CNG fuelling stations by the end of 2025. Stations are already being planned for Kamloops, Fort St. John and Chilliwack, B.C., as well as Fort McMurray, Alta.
