Rio Tinto completes conversion of Kennecott heavy mining fleet to renewable diesel use

Rio Tinto has completed the transition from conventional to renewable diesel for all heavy mining equipment at its Kennecott copper mine in Utah, giving the mine one of the lowest carbon footprints of any copper producer in the US, it claims.

Kennecott’s fleet of 97 haul trucks and heavy machinery equipment at the mine, concentrator, smelter, refinery and tailings are now all fuelled by renewable diesel (a combination of 90% soybean and the remainder animal fat and used cooking oil) sourced in the United States. This is expected to reduce the mine’s Scope 1 emissions by 450,000 t, equal to eliminating the annual emissions of 107,000 cars. In addition, the switch to renewable diesel reduces PM2.5 (particulate matter less than 2.5 microns) emissions at the tailpipes of its haul truck fleet by 40%, a reduction equivalent to approximately 2,300 million miles of light vehicle travel annually.

“Kennecott has one of the lowest carbon footprints of any copper producer in the United States, thanks to recent initiatives such as the closure of a coal-fired power plant, installation of a 5 MW solar farm, deployment of battery-electric vehicles underground, and the transition to renewable diesel,” the company says. “The operation’s overall carbon footprint has now been reduced by more than 80% from 2018 levels.”

Speaking at an event on site with the Governor of Utah, Spencer J Cox, to celebrate the achievement, Rio Tinto Copper Chief Operating Officer, Clayton Walker, said: “The transition to renewable diesel is a significant step toward our decarbonisation goals at Kennecott where we have now reduced emissions by 80%, thanks to a range of initiatives in recent years. We remain committed to being responsible stewards of the environment and are always looking to find better ways to provide the materials the world needs for the energy transition.”

Kennecott’s transition to renewable fuel will also make low-carbon fuel more accessible in the state of Utah. In partnership with Kennecott, HF Sinclair is dedicating two tanks to renewable diesel for the mine with each having tank capacity of 18,000 barrels or 756,000 gallons.

HF Sinclair Executive Vice President, Commercial, Steven Ledbetter, said: “We’re proud to support Rio Tinto’s sustainability journey with a low-carbon fuel produced at our facilities. We’re excited to see Kennecott move from trial to full implementation and what this could mean for other industries with evolving energy needs.”

In 2023, Kennecott conducted an initial trial of renewable diesel, which compared two trucks using regular diesel against two using renewable diesel. Officials measured the trucks’ acceleration, cycle time, fuel usage and engine inspection reports. The renewable diesel was trialled successfully, complementing similar test findings from Rio Tinto’s Boron mine in California.

Combined with Rio Tinto’s Boron mine – which completed the full transition of its heavy machinery from fossil diesel to renewable diesel in May 2023 – renewable diesel use at Kennecott replaces 11% of Rio Tinto’s global fossil diesel consumption with renewable diesel.

Rio Tinto is targeting reductions in Scope 1 and 2 emissions of 50% by 2030 and net zero by 2050.

Rio Tinto to move to 100% renewable diesel at Kennecott copper operation

Rio Tinto will replace its entire fossil diesel consumption with renewable diesel at its Kennecott copper operation in Utah from 2024, the mining company has confirmed.

Kennecott’s fleet of 90 haul trucks and all heavy machinery will begin to transition to renewable diesel in the March quarter of 2024, along with consumption from the concentrator, smelter and refinery. HF Sinclair is set to provide the fuel.

The transition will reduce Kennecott’s Scope 1 carbon emissions by approximately 495,000 t/y of CO2 equivalent, comparable to eliminating the annual emissions of more than 107,000 passenger cars.

The renewable diesel is made from renewable biogenic materials sourced in the US. It will be supplied through the existing diesel supply chain, as part of a continuing partnership between Kennecott and HF Sinclair.

Rio Tinto Copper Chief Operating Officer, Clayton Walker, said: “Transitioning Kennecott completely to renewable diesel builds on a suite of decarbonisation initiatives that have reduced carbon emissions from the operation by 65% since 2019. This is an important next step in our commitment to finding new and better ways to reduce operational emissions, while producing materials essential to the global energy transition.”

HF Sinclair Executive Vice President, Commercial, Steven Ledbetter, said: “As a long-time supplier of Rio Tinto and a fellow operator in the Rocky Mountain region, we are pleased to support Rio Tinto’s sustainability journey with a low-carbon fuel made at our facilities. This is a great step demonstrating our continued progress to meet the evolving energy needs of our customers.”

Rio Tinto is targeting reductions in Scope 1 and 2 carbon emissions of 50% by 2030 and net zero by 2050.

Rio Tinto Chief Decarbonisation Officer, Jonathon McCarthy, said: “Combined with Rio Tinto’s U.S. Borax operation – which completed the full transition of its heavy machinery from fossil diesel to renewable diesel in May 2023 – this initiative would replace 11% of Rio Tinto’s global fossil diesel consumption with renewable diesel.

“The use of drop-in fuel such as renewable diesel will allow Rio Tinto to reduce emissions in the short term, complementing ongoing work towards the commercial readiness of longer-term technical solutions such as battery electric haul trucks.”

The decision to convert to renewable diesel comes after a successful seven-month trial at Kennecott’s Bingham Canyon mine. This trial was conducted in collaboration with Cummins to test renewable diesel in different operational environments and on different equipment which supported the decision of OEM to approve the use of renewable diesel in Rio’s equipment.

Petro-Canada Lubricants releases PRODURO TO-4+ UHP fluid to boost equipment productivity

Petro-Canada Lubricants, an HF Sinclair brand, has launched PRODURO™ TO-4+ UHP, a multi-purpose synthetic all-season transmission, hydraulic, drive line and wet brake fluid for heavy-duty mobile equipment that, the company says, increases equipment productivity and decreases operating costs.

Developed to improve the performance of mining and construction equipment operating in extreme conditions, PRODURO TO-4+ UHP maximises durability and equipment protection at elevated system temperatures and in severe operating conditions, it says.

Offering improvement in High Temperature High Shear and in-service viscosity, as well as the potential to safely extend oil drain intervals, PRODURO TO-4+ UHP can deliver significant cost savings for equipment operators, Petro-Canada Lubricants claims.

During a more than two-year long customer trial, the fluid demonstrated the ability to meet the requirements of the Caterpillar TO-4 specification, increase equipment life by up to 6% and deliver significant cost savings based on 25 units for a large Canadian mine operating across two sites, according to the company.

The advanced fluid can also eliminate seasonal change-outs for hydraulics, wet brakes, drive trains and transmissions without compromising the lubricant performance or equipment wear. Due to the fluid’s ability to prolong equipment life, PRODURO TO-4+ UHP can also help support a mining operation’s sustainability goals, the company says.

Sharon Perichak, Segment Marketing Manager for Mining at Petro-Canada Lubricants, said: “PRODURO TO-4+ UHP is a game changer. Working closely with our trial partner, we developed this fluid to extend transmission life and hours of service while reducing running costs. For years we have been supporting mining operators and equipment owners to overcome their lubricant challenges and optimise equipment performance. This ethos and collaborative approach has been at the forefront of the innovation and development behind PRODURO TO-4+ UHP and we are delighted to offer equipment operators the step-change in protection the transmission fluid delivers.”
