Emerging Technologies: Mining Electrification

November 10, 2022

Leading-edge technology is integral to reducing greenhouse gas emissions on a global scale, and Pathways Alliance companies have a long track record of world-class research and development (R&D) partnerships and investments to build on.

For more than a decade, much of that collaborative work to create a sustainable future has been coordinated by Canada’s Oil Sands Innovation Alliance (COSIA), now the innovation arm of Pathways Alliance.

Our emerging technologies series looks at some of the work being done by COSIA and the six member companies who make up the Pathways Alliance.

This feature focuses on the electrification of mining.

The next generation of mining technologies is revolutionizing oil sands mining operations, carrying the sector into the digital age. An array of innovation, everything from automated truck fleets to artificial intelligence, is significantly reducing greenhouse gas emissions, boosting safety and efficiency, and lowering operating costs across mine sites in Canada and around the world. In Alberta, about 20 per cent of the oil sands is shallow enough to be mined and innovation success here is delivering a wide range of environmental and economic benefits.

“Materials handling is a big part of mining and a significant cost for the industry,” explains Anthony Van Tol, Mine Automation Project Engineer at Suncor and one of several member representatives who lends his expertise to COSIA’s Mining Working Group. “We’re looking for ways to move materials more efficiently and reduce emissions. This is a big push across the mining sector.”

Van Tol is involved in a project to reduce the reliance of mine haul truck fleets on diesel fuel. These giant vehicles transport materials from the mine face to processing facilities and are the primary source of emissions on site. Some of the approaches the group is investigating are cleaner fuels, improving haul truck design, and implementing trolley (electric) assist. The group collaborates with the Canadian Mining Innovation Council (CMIC) to evaluate new technologies and engages with industrial truck manufacturers to align research efforts.

Statistics show mining trucks run at peak power about 30 per cent of the time, which means that 70 per cent of the time, power is wasted idling. What if the trucks could access power when they needed it, just the right amount at the right time? That’s what electrification achieves. The proven technology has been successfully applied to mining in other parts of the world and is now being adapted for the oil sands.

It involves replacing a truck’s mechanical drive and diesel motor with an electrical drive and battery. Overhead trolley lines are installed on main transportation routes and the truck is fitted with a rooftop contact system to access power. “The trucks hook on and off the overhead line as and when they need to,” Van Tol explains. “When they connect, they run off electricity and when they disconnect, they run off battery. It’s very efficient because the truck only takes the power it needs.”

Other vehicle enhancements include regenerative braking, an energy recovery mechanism that kicks in when trucks go downhill. When braking, the vehicle makes use of a generator to slow down the vehicle, while also generating power that goes back into the electricity network. “All these improvements support efficiencies in the running of your entire fleet,” Van Tol notes. As innovation proves viable, best practices are shared among Pathways Alliance members and more broadly, delivering benefits across the mining industry, he says.

All told, the Pathways Alliance is developing and deploying more than 70 emerging technologies to drive sustainable development of the oil sands and support Canada’s efforts to meet its emissions targets.

Forward-looking statements can be identified by words such as achieve, aspiration, believe, anticipate, intend, propose, plan, goal, seek, project, predict, target, estimate, expect, forecast, vision, strategy, outlook, schedule, future, continue, likely, may, should, will and/or similar references to outcomes in future periods. Forward-looking statements in this press release include, but are not limited to, references to the viability, timing and impact of the Oil Sands Pathways to Net Zero initiative collaboration and the development of pathways in support of a net-zero future; support for the pathways from the Government of Alberta and the Government of Canada; the ability to enable net zero emissions from oil production and preserve economic contribution from the industry; the continued role of fossil fuels as part of a diversified energy mix; and the deployment of technologies to reduce GHG emissions, such as CCUS, process improvements, energy efficiency, fuel switching, electrification, infrastructure corridors and new emissions-reducing technologies. All net-zero references in this announcement apply to emissions from oil sands operations (defined as scope 1 and scope 2 emissions).

Forward-looking statements are based on current expectations, estimates, projections and assumptions at the time the statements are made. Actual future results, including expectations and assumptions concerning: demand growth and energy source, supply and mix; amount and timing of emissions reductions; the adoption and impact of new facilities or technologies, including on reductions to GHG emissions; project plans, timing, costs, technical evaluations and capacities, and the ability to effectively execute on these plans and operate assets; that any required support for the pathways from the Government of Alberta and the Government of Canada will be provided; applicable laws and government policies, including climate change and restrictions in response to COVID-19; production rates, growth and mix; general market conditions; and capital and environmental expenditures, could differ materially depending on a number of factors. These factors include global, regional or local changes in supply and demand for oil, natural gas, and petroleum and petrochemical products and the resulting price, differential and margin impacts; political or regulatory events, including changes in law or government policy and actions in response to COVID-19; the receipt, in a timely manner, of regulatory and third-party approvals including for new technologies; lack of required support from the Government of Alberta and the Government of Canada; environmental risks inherent in oil and gas exploration and production activities; environmental regulation, including climate change and GHG regulation and changes to such regulation; availability and allocation of capital; availability and performance of third-party service providers; unanticipated technical or operational difficulties; project management and schedules and timely completion of projects; reservoir analysis and performance; unexpected technological developments; the results of research programs and new technologies, and ability to bring new technologies to commercial scale on a cost-competitive basis; operational hazards and risks; general economic conditions, including the occurrence and duration of economic recessions; and other factors referenced by the companies’ in their most recent respective annual reports and management’s discussion and analysis, as applicable.

Forward-looking statements are not guarantees of future performance and involve a number of risks and uncertainties, some that are similar to other oil and gas companies and some that are unique to the companies. Actual results may differ materially from those expressed or implied by its forward-looking statements and readers are cautioned not to place undue reliance on them. The companies undertake no obligation to update any forward-looking statements contained in this press release, except as required by applicable law.
