Are natural gas-fuelled vehicles the way of the future?
Automotive analyst Dennis DesRosiers says governments should stay out of picking winners and losers.
CALGARY — Proponents of natural gas-fuelled vehicles say they can help reduce carbon emissions now but government support is needed to get businesses on board.
The alternative fuel has been around for decades but new technology developments and greater awareness of the need to bring down emissions has led to heightened interest, said Bruce Winchester, executive director of the Canadian Natural Gas Vehicle Alliance.
“We see some opportunities and some real potential, particularly as governments start to look at transportation as a source of greenhouse gas emissions,” he said.
Like most alternative fuels, natural gas still only makes up a small fraction of the fuel powering the total number of vehicles on the road. But Winchester said he sees potential for growth in medium- and heavy-duty fleet vehicles, where energy demands are higher.
Natural gas has about 15 per cent less greenhouse gas emissions than diesel. That can translate into a far bigger impact if trucking fleets are converted to use natural gas.
“You’re going to get bigger emissions savings when you look at an application that requires a lot of kilometres and therefore a lot of fuel burned,” he said.
He pointed to C.A.T. Transportation in Quebec that as of February had switched 20 trucks to compressed natural gas for long-haul transportation down to Texas. The company said that as a result, in the first six weeks of the year it saved 18 tonnes of carbon dioxide.
But Winchester said carbon prices are too low or non-existent to make it enough of a financial incentive to switch, especially with diesel prices at their lowest in years, which is why the industry is hoping for government help.
Ritch Murray, manager of Enbridge Inc.’s natural gas transportation division, says the $200 million for lower-emission vehicles and refuelling stations mentioned in a leaked version of Ontario’s draft climate plan would go a long way.
“That’s going to be some welcome investment,” said Murray. “These are businesses and they’re looking at the bottom line. And if there’s not an incentive to fuel switch, they’re going to think twice about it.”
British Columbia and Quebec already have some forms of natural gas vehicle incentives. A spokesman for Alberta’s environment minister said the government could consider alternative fuelling options through the energy efficiency program once it’s established.
The federal government also promised $62.5 million for alternative fuels in its latest budget, but almost all of that is going towards electric vehicle infrastructure.
Murray, who manages the largest commercial natural gas vehicle fleet in Canada at Enbridge, says that for heavier-duty vehicles there aren’t really electric options, but natural gas is ready to go.
“It’s readily deployable, commercialized technology that has an immediate impact on GHGs and we can get it out right now in the heavy duty space, where there aren’t any electric options,” said Murray.
But with so many competing vehicle fuel alternatives, automotive analyst Dennis DesRosiers says governments should stay out of picking winners and losers.
“It’s not the government’s job to decide whether it’s going to be natural gas or diesel in the future,” he said. “Just set a standard and let industry figure it out.”
