Epiroc’s range of drill rigs, mine trucks and loaders for underground applications are now verified to be compatible with HVO100. This alternative fuel reduces particulate tailpipe emissions and other harmful substances, including greenhouse gases.

Rickard Johansson, Vice President Marketing at Epiroc’s Underground division, said: “By switching from fossil diesel to HVO100, customers can reduce CO2e emissions in operations by up to 1,000 tonnes per year, using a Minetruck MT42 S as an example. We are very proud to offer this alternative energy source to support our customers in the transformation towards more sustainable mining operations.”

HVO100 (Hydrotreated Vegetable Oil) can serve as a direct replacement for fossil diesel or be used in a blended form. When used in diesel engines, this renewable fuel can reduce CO2e emissions by up to 90%, according to Neste, compared with conventional fossil diesel, depending on operating conditions and production methods.

Ulrika Ford, Global Sustainability Manager, Epiroc Underground division, added: “Epiroc has ambitious sustainability targets for 2030, and we continuously strive to improve our offering by finding more sustainable customer solutions. The ability to use HVO100 in our underground rigs, loaders and trucks is an important step towards meeting these targets and helping our customers lower their carbon footprint.”

Moving from fossil diesel to HVO100 does not require any changes to service, installation or infrastructure, as it works similarly to mineral diesel, according to Epiroc. This makes the transition to HVO100 a smooth and practical alternative solution, it says.

HVO100 can be used in all underground drill rigs, mine trucks and loaders produced from December 2022. For compatibility with earlier models, and for machines already in the field.

Epiroc says it is committed to halving CO2e emissions in our own operations. For example, in the product company in Örebro, Sweden, fossil diesel usage is being phased out and all machines are now fuelled up with HVO100 instead.

In November 2023, Epiroc announced HVO100 compatibility for surface drill rigs.

Rokbak is highlighting its four product focus areas – innovation, sustainability, connected services and efficiencies – at CONEXPO-CON/AGG 2023, in Las Vegas, this week, as the articulated hauler manufacturer says it continues to prioritise the customer and environment to meet industry challenges head-on.

Rokbak is using its presence at CONEXPO to highlight four connected product focus areas that will continue to shape the company’s development journey and have been created from customer feedback, market research, technology advancements and product performance improvements. The four themes are innovation, sustainability, connected services and efficiencies – and they encompass everything from future product developments to reducing operational costs, it explained.

“We’re always innovating, designing and building to keep our haulers rock solid,” Rokbak’s Senior Product Manager, Scott Pollock, said. “Since the success of our rebrand 18 months ago, we are now moving into the next phase of the Rokbak development journey. Our four product themes will be used to develop both Rokbak’s future product and product services offerings, aligned to customer needs.”

Innovation

One of the future developments that Rokbak is currently working on is its next generation cab for the RA30 (30-t payload) and RA40 (40-t payload) articulated haulers. Key benefits of the new design include higher levels of operator comfort and improved performance, modern ergonomic layout and displays, ease of operation and future proofing functionalities for automation and connectivity.

Other areas under this theme include using technological advances, modern component specifications and fuel economy to reduce customer operating costs. These reductions have been achieved through things including extended time between scheduled maintenance, fuel efficiencies, longer life fluids and filter systems. This has led to an average cost reduction for the EU Stage V/US Tier 4 Final RA30 of 19%/h, and 10%/h for the RA40, the company claims.

Sustainability

As part of the Volvo Group, Rokbak’s long-term plans are aligned with the group’s sustainability values. This includes the Volvo Group target to reach net-zero greenhouse gas emissions by 2040.

Rokbak is reviewing technical solutions that will allow it to achieve its sustainability goals. All Rokbak haulers are built for low fuel consumption and global CO2 emissions compliance. Both the RA30 and RA40 are compatible with hydrotreated vegetable oil, which allows customers to significantly reduce CO2 emissions.

Connected services

Rokbak’s improved Haul Track telematics system is helping machine owners manage total cost of ownership by keeping an eye on everything from fuel consumption and machine usage, to problems that if neglected could lead to repairs or unplanned downtime. The bespoke system gives customers more visibility and control of their machines with live data viewable on desktop computers and mobile devices, according to Rokbak. This includes: locating equipment and monitoring productivity and operational costs by keeping track of everything from scheduled maintenance planning, early fault warning and performance management information.

Haul Track is now AEMP-enabled, allowing for mixed fleet management via a single communication platform, Rokbak says.

Efficiencies

Rokbak says its fuel-efficient drivetrains deliver powerful performance and meet worldwide emission standards with low cost of operation and low environmental impact. The high performance drivetrain has responsive, usable power with adaptive shifting for low fuel consumption and operating costs.

Another efficiency aspect of the Rokbak design is easy service access, making the RA30 and RA40 quick and simple to maintain with ground-level test points, electric-lift hoods and tilting cabs, enabling high uptime and productivity.

“Rokbak haulers deliver new benchmarks in both performance and total cost of ownership, and reinforce the company’s commitment to sustainability and journey to net-zero as part of the Volvo Group,” Pollock concludes. “Customer needs will continue to guide our product strategy and we will continue to invest in our Rokbak products and services.”

BHP is trialling the use of hydrotreated vegetable oil (HVO) to help power mining equipment at its Yandi iron ore operations in Western Australia.

Supplied through a collaboration with bp, the renewable diesel made from HVO will be used in haul trucks and other mining equipment over an initial three-month trial period, the miner says.

BHP Western Australia Iron Ore (WAIO) Asset President, Brandon Craig, said: “About 40% of BHP’s operational greenhouse gas emissions come from using diesel fuel, and this is a core focus of our decarbonisation strategy. Ultimately, our aim is to have fully-electric trucking fleets at our sites, but alternative fuels like HVO may help us reduce our emissions in the meantime while the electrification transition takes place.

“This collaboration with the teams at Yandi and bp is really exciting to see, given the potential application in our WAIO business and BHP’s operations globally.”

bp President Australia, and SVP Fuels and Low Carbon Solutions, Asia Pacific, Frederic Baudry, said: “bp’s ambition to be a net-zero company by 2050 or sooner, and to help the world get to net zero, recognises the crucial role bp has to play in the energy transition.

“Globally, bp plans to increase its investment in low-carbon energy. Forging strategic partnerships with companies like BHP enables bp to create solutions that satisfy the increasing demand for lower carbon fuels in sectors like mining and transport.”

BHP has a medium-term target to reduce operational greenhouse gas emissions by at least 30% by its 2030 financial year, from an FY2020 baseline. Approximately 40% of BHP’s operational emissions in its FY2020 baseline year came from diesel-powered equipment.

The HVO is to have internationally recognised certification as being sourced from more sustainable feedstocks such as waste products.

Shell on the future of fuel switching

Mark Hannan, General Manager for Mining Decarbonisation at Shell, explores how mining operators can switch their fleets from diesel to low-carbon fuels as part of a wider transition to zero-carbon fuels.

The mining industry is in need of decarbonisation but delivering change at pace is a real challenge. There is huge pressure to achieve this when, it is estimated, 10% of the world’s energy-related greenhouse gas (GHG) emissions come from primary minerals and metals production, according to Nature Geoscience Magazine (2020).

For a mining company to achieve their decarbonisation goals, it is beneficial to maximise the benefits in the short term while providing greater flexibility for the long term. One such area that offers opportunities for this is fuel switching in mining fleets.

Decarbonisation drives the need for alternative fuels

No matter what stage a mining business has reached on its pathway to decarbonisation, it is important to review how its mobile assets impact the environment. McKinsey shows that between 40-50% of CO2 emissions in mining come from the diesel used for mobile assets.

Due to concerns around diesel fumes in confined spaces, the problem is largely being solved in underground sites – with some due to run entirely on battery-electric assets in the near term. In open-pit mines, where equipment is larger, emissions from diesel fuel are a challenge still to overcome, which is why fuel switching is essential to decarbonisation.

However, there are still many elements to consider when making the business case for alternative fuels. This includes the performance of alternative fuels in comparison with diesel, the capital investment needed to implement them and how widely available they are. That is before analysing the benefits of meeting emissions targets against the higher cost of using low-carbon fuels.

A net-zero future is coming, but it is not here yet

In the longer term, there are two diesel alternatives that will offer key routes to effective fuel switching: hydrogen and electricity.

Hydrogen is set to play a significant role in the decarbonisation of every industry – not least those featuring hard-to-abate sectors like mining. As well as reducing emissions in overall energy use across sites, hydrogen will provide a low-carbon alternative to diesel that also delivers higher energy density to drive the performance of mobile assets.

Government support for hydrogen power is growing rapidly and it is an area in which Shell is working closely with customers and original equipment manufacturers (OEMs) to drive innovation and deliver supply at scale. However, with hydrogen supply dependent on elements such as the availability and cost of technology, land, water, storage and transport, it is an alternative that will only start to present real impact from 2030 and beyond.

For off-highway equipment in mining, fleet electrification is often seen as a more relevant near-term solution. This is not surprising as electric power can not only contribute to reduced emissions but also help businesses shift away from their exposure to volatile diesel prices – potentially leading to a positive impact on total cost of ownership (TCO).

To help deliver on the mining industry’s longer-term aspirations for fleet electrification, Shell is developing a suite of modular end-to-end solutions for mining heavy-duty vehicles that decarbonises haul trucks while minimising the operational impact of electrification in a scalable, interoperable and sustainable way.

When looking to make the switch to electrification, mining companies must address the significant escalation in power demand that would come with full-scale electrification. Also, they will want to know the electricity is generated from renewable sources – helping them to reduce their Scope 1 and 2 emissions. Electrification powered by renewable energy will be a significant driver of change for mining sites, which is why Shell is working to overcome the barriers to increasing its renewable capacity – such as the need for upgrades to the grid and storage capabilities.

Low-carbon fuels offer an immediate next step for mining businesses

Hydrogen and electrification represent the future of fuel for mobility in mining. But, in the short term, there is another alternative that can act as a transition fuel and help lower emissions while businesses wait for hydrogen and electricity to become viable at scale: low-carbon fuels.

There are two types of low-carbon fuels relevant to mobility in mining:

  • Biodiesel – also known as Fatty Acid Methyl Ester (FAME); and
  • Renewable diesel – also known as Hydrotreated Vegetable Oil (HVO)

Though both are derived from organic biomass like waste vegetable oils and animal fats, there are differences in their chemical composition owing to a different manufacturing process that impact their use. For instance, biodiesel is the more affordable choice, yet most OEMs place a limit on the percentage it is possible to blend with conventional diesel due to quality concerns such as storage stability and performance in cold temperatures. Renewable diesel more closely resembles the composition of conventional diesel, meaning it can be blended in any ratio up to a concentration of 100%, but is more expensive due to the complexity in refinery processing. Crucially, both fuels offer a route to emissions reduction in mining – and a combination of the two is likely to be needed.

These low-carbon fuels offer a more immediate solution to the challenges of fleet decarbonisation in mining, without making costly investments in infrastructure. Not only can they be used in existing heavy-duty diesel engines, but, as long as they are in accordance with manufacturer advice, they also require no infrastructure investment. This makes them a more affordable short-term option that enables businesses to reduce emissions today while working to implement the ecosystem needed to transition to hydrogen and electricity tomorrow.

Overcoming the challenges of availability at scale

The merits of low-carbon fuels for a sites’ mobility needs might already be clear. After all, the technology is mature and it is easy to implement – certainly compared with hydrogen and electricity. However, there are still barriers to overcome before we see widespread adoption in the mining industry.

Availability and affordability are the two critical challenges. Despite its maturity, supply of low-carbon fuels is tight – especially given the remote regions that mining operations usually take place in. The need to comply with regional regulations on renewable fuels is also driving rising demand. For example, the EU Commission’s renewable energy directive has proposed increasing its target for renewable energy sources consumption by 2030 to 45% (up from its current goal of 32%).

Also, mining is not the only sector looking to alternative fuels to drive decarbonisation, meaning businesses will need to compete and trade with areas like commercial road transport to source low-carbon options. With more users needing access to alternative fuels, premiums for low-carbon fuels remain high. This can make low-carbon fuels less affordable and risks undermining any TCO improvements businesses can expect to realise from fuel switching.

It means that businesses are hesitant to act today as they wait for more capacity and greater competition to arrive – even though mining cannot afford to delay its emissions reduction efforts. That is why, at Shell, we are working to deliver additional capacity and competition. As well as investing in new production facilities (including a new biofuels facility in the Shell Energy and Chemicals Park Rotterdam, which will produce sustainable aviation fuel and renewable diesel made from waste in The Netherlands once it comes onstream), we are using our existing relationships with OEMs to help mining businesses get the most out of the low-carbon fuels they do have access to.

Collaboration will be critical to fuel switching success

Ultimately, if mining businesses are to meet their regulatory responsibilities while driving performance, they will need to unlock the opportunity that fuel switching provides. From low-carbon fuels to electrification to hydrogen, there is huge potential to reduce emissions while improving the TCO of mining mobility.

Successful fuel switching will require close collaboration with partners and suppliers to create a new fuel ecosystem by improving the availability and affordability of alternatives to conventional diesel. Only by working together will we deliver a new fuel future for mining, which is why Shell Mining is committed to supporting the industry on every step of its decarbonisation journey.

Sandvik and Finning partner on HVO biodiesel use in crushing, screening equipment

Environmental, Mining equipment, Mining services, Sustainable mining, , , , , , , , , ,

Sandvik’s Mobiles business unit and Cat dealer Finning say they have successfully tested hydrotreated vegetable oil (HVO) with C series Cat® engines without making any modifications to the engine or fuel tanks.

The test could pave the way for the renewable synthetic diesel powering large, mobile crushing and screening equipment from Sandvik, the OEM said.

Forming a part in both company’s journey towards a more sustainable future, the use of HVO reduces net carbon emissions by up to 90% compared with conventional diesel, the companies say, with the HVO used by the companies only made from renewable feedstocks certified by The International Sustainability & Carbon Certification.

Its performance is similar to regular diesel, so the power output and uptime are not compromised, according to the companies.

The companies explained: “Hydrotreating of vegetable oils is a modern way to produce very high-quality renewable diesel fuels without requiring any changes to fuel logistics, engines, or exhaust aftertreatment devices. Unlike other biodiesels, HVO is not sensitive to low or high temperatures, or indeed to exposure to sunlight, as all oxygen is removed during the production process. Also, due to the use of hydrogen in the production process, HVO has an impressive shelf life, compared to other biodiesels. Since no iron or system changes are required, it can be considered a drop-in replacement for diesel.”

Jesper Persson, Vice President Life Cycle Services at Sandvik Mobiles, said: “We are committed to using engineering and innovation through our products to make the shift towards more sustainable business. With a host of innovations in the pipeline, including electrification of our offering, we are excited to be pioneers in the industry and invest in renewable fuel sources sustainable rock processing solutions.

“Working alongside Finning to performance-engineer the feasibility of HVO means we can collect data and monitor any impact on the performance and output. It’s an exciting step in our contribution to sustainability and we will work together with our customers and suppliers for more productive, safer, and innovative solutions.”

Steffen Barrett, Sales Manager – Industrial Engines, Finning UK & Ireland, said: “As Sandvik strive to balance environmental and business sustainability, we are ready to provide the solutions they need to achieve their goals. Our customers’ priorities are evolving toward a carbon-reduced future and our products and services are evolving with them.

“We are actively supporting the use of plant-based and waste-derived fuels in our engines as alternatives to traditional fuels. Our engines are engineered for use with a range of renewable fuels, including up to B100 HVO (EN15940 or ASTM D975), that have a significantly lower net carbon footprint than conventional diesel.”
