Thiess’ sustainability drive accelerates in 2023

With the release of its 2023 sustainability report, Thiess says it has advanced its journey towards sustainable mining, reducing its emissions and diversifying its commodities and services.

Further progress was made towards its 2025 decarbonisation target, reducing Scope 1 emissions by 21% and Scope 2 emissions by 12% during 2023.

These efforts were further enhanced by the group’s diversification of its commodities and services, to rebalance its thermal coal revenue to less than 25% by the end of 2027, which is tracking ahead of schedule. Recognising this, the group has now set an additional diversification target to rebalance its portfolio to consist of less than 20% thermal coal revenue by the end of 2030.

“The group remains committed to supporting a smooth energy transition and will continue to provide sustainable mining services to its thermal coal clients as the use of this commodity continues to support economic growth in many societies,” it said.

These goals have been set alongside the release of Thiess’ 2023 sustainability report, which, itself, reported on several projects helping the decarbonisation cause.

To progress its target of 85% of light vehicles being electric or hybrid by 2030, Thiess began battery electric and hybrid light vehicle trials in Australia, North America and Chile, in 2023, with similar trials expected to begin in Indonesia in 2024.

In Chile, Thiess formalised an agreement to lease two Voltera R6 electric cars, each with a range of 280-300 km, which were delivered to the Llanos copper project in October. This initiative aims to reduce emissions by approximately 7.2 t CO2-e each year. Thiess also partnered with Hualpen, a Chile-based transport company, to trial the use of an electric bus to transport personnel during shift change from the city of Calama to the Llanos copper project, in Minera Centinela, approximately 100 km away. The use of the electric bus results in an estimated emissions saving of approximately 140 kg CO2-e per trip, which Hualpen estimates will result in a total emissions saving of approximately 15 t CO2-e per year.

In the US, Thiess investigated the application of an electric 4×4 light vehicle in the challenging weather conditions at its molybdenum site. The site is around 3.5 km above sea level with temperatures often dropping to -20°C. The chosen engineered solution uses a Hypercraft electric drive system to convert a heavy-duty designed Ford F-250 Super Duty 4×4 (pictured). This fully-electric solution provides a range of 160-225 km and was deployed in December 2023.

At the Mt Pleasant operation in New South Wales, Australia, Thiess has introduced two electric vehicles (EVs) – a Polestar 2 and Kia EV6 – and a hybrid Mitsubishi Outlander, as pool cars. The vehicles provide personnel with an opportunity to trial the experience of driving an EV to encourage wider adoption. Two ABB 22 kW electric chargers were installed to support the trial with a third installed for use by employees and visitors who drive EVs to site.

Outside of light vehicles, Thiess, through MACA, welcomed the first Liebherr R 9300 250-t excavator in Australia into its growing fleet at the Karlawinda gold project in Western Australia. Commissioned in August 2023, the R 9300 uses innovative technology to provide improved performance and better fuel efficiency, Thiess says. Thiess also introduced Komatsu 930E-5 electric drive trucks, with tier 4 engine technology, at two Australian projects to enhance operational efficiency. The trucks are expected to deliver a 5% reduction in fuel consumption compared to other trucks in their class, it says.

In 2023, the MACA team at the Okvau gold project in Cambodia worked with its supplier to reduce the compressor power of all drill rigs to 90% to improve efficiency and reduce fuel consumption and emissions. Since the implementation of the initiative in June 2023, fuel consumption across all six Epiroc drill rigs has been reduced by an average of 20%. This equates to an annual saving of approximately 165,000 litres of fuel and 570 kg of CO2-e emissions. Thiess said: “MACA intends to continue with the reduced compressor power as there has been no adverse effects since the initiative was implemented. Drill performance in normal conditions has been unaffected and no maintenance issues have been reported.”

Building on the success of the initiative, the aim is to extend the modifications to remaining drill rigs of the same model within its fleet.

Also during 2023, Thiess completed a study to determine the optimum horse power (HP) setting for the Cat 794AC trucks at a Queensland project based on application, production capability and fuel burn. The study allowed Thiess to identify the most appropriate setting, considering tonnes moved and fuel consumed, and calculate component life targets based on each setting. The trial resulted in fuel savings of 15.79% across a fleet of seven 794ACs by reducing the HP setting from 3,500 HP to 3,100 HP. According to internal calculations this equated to a saving of A$1.68 million ($1.11 million) per year in fuel, $180,000 in life extension and an annual reduction in emissions of 3,790 t CO2-e.

The site team concluded there was no reduction in asset performance, however the trial indicated a reduction in truck productivity of 4.72%. Although this is a bespoke situation, Thiess says it will look to identify similar cases at other sites where the trial findings may be utilised.

In September 2023, Thiess launched the Thiess Remote Operation Centre (TROC) In Jakarta, Indonesia. Using leading technology, TROC supports fleet management at the Wahana mine over 1,000 km away. This remote technology can help to improve efficiency and productivity of the mining fleet, Thiess says.

Thiess will look to implement the technology at its MSJ mine next, allowing TROC to support additional mines as Thiess continues on its digitisation journey.

Thiess also completed a hydrogen trickle feed trial on 40% of its haul fleet at the Prominent Hill operation in South Australia, in 2023 (now owned by BHP). Findings have been leveraged with the aim to initiate a second trial at a New South Wales project in 2024.

In 2024, Thiess plans to begin trials of hybrid excavators in Indonesia and battery-powered light/medium trucks in Australia, continue dual fuel trials and MACA’s pursuit of fleet retrofit solutions in Australia, complete an additional hydrogen trickle feed technology trial and investigate more fuel-efficient options for its asset rebuilds, it says.

INTERMAT to showcase zero carbon transition across construction sector

The next edition of INTERMAT, the sustainable construction solutions and technology exhibition, will take place from April 24-27, 2024, at Paris Nord Villepinte exhibition centre, in France, with large international manufacturers having already signed up.

To date, and since the round table held on April 20 with the entire construction sector, new names have confirmed their attendance at the show, including Ausa, Epiroc, Faymonville, Liebherr, Magni and Volvo. They join the registered exhibitors whose participation had already been announced: Alphi, Bobcat, Cummins, Imer, Komatsu, Groupe Monnoyeur, Putzmeister, Sany, Sateco, Schwing Stetter, Sunward, Takeuchi, Topcon and Wacker Neuson.

Davy Guillemard, CEO of Volvo Construction, said: “INTERMAT 2024 has reinvented itself to address the issues of the decarbonisation of the construction industry, adapt to environmental constraints, and advance along the road to sustainability. As these commitments are particularly close to the fundamental values and ambitions of the Volvo Group, which is resolutely determined to be a proactive leader in change and accelerate on the low carbon path, we have chosen to invite our clients and partners to meet us at INTERMAT 2024 to present them with all our low carbon solutions at their disposal.”

François Escourrou, CEO of Wacker Neuson, said: “The next INTERMAT show, with its low carbon theme, is keenly awaited by our group which has set itself the goal of cutting its carbon dioxide emissions by 50% in 2025 compared with 2019. To do so we have opted to convert our machines to electric power to support our clients in their CSR policy. We will therefore have a lot of new products to present at INTERMAT in 2024 in terms of equipment, with around 40 new machines in the electric range, but also in terms of associated services and digitalisation.”

Olivier Saint-Paul, CEO of PL2M, said: “At PL2M, the screed and rendering machine market leader, we look forward to taking part in the next INTERMAT 2024 and bringing our contribution to the zero carbon transition of the building sector. The event offers the chance to present new solutions that are resolutely focussed on the future, rounding out our ranges of rendering machines, fluid screed pumps and traditional screed conveyors. Our brands Putzmeister, Lancy and Brinkmann will be showcased on our stand with a great many innovations for ever higher performances and safety on building sites, and less environmental impact.”

The four major challenges of construction

The 2024 edition, in its move to gather the entire construction industry around a shared vision of the future, aims to harness its collective excellence to address the sector’s major issues in terms of decarbonisation and energy, digitalisation, CSR commitment, training and employment, and organise a platform for dialogue with the public authorities. To do so, it will draw on four main pillars that will offer highlights and developments featuring in the four main challenges for construction.

1) Innovations – innovate to find solutions to the major challenges faced by construction

Industry Forum (new in 2024) bringing together the five main construction federations DLR, EVOLIS, UMGO-FFB, FNTP, SEIMAT: an agora featuring a series of talks and round tables with top-level speakers, construction professionals, official authorities, French and international special guests, and perspectives from other sectors to address zero carbon issues from all angles and in a forward-looking dimension.

World Of Concrete Europe Forum: a series of talks dedicated to the concrete industry, the material and its various applications; INTERMAT Innovation Awards: a competition reflecting the sector’s new challenges, and unique visibility before and during the show with a dedicated display area; INTERMAT Press Days: two days of workshops and discussions on 18 and 19 January 2024 between exhibitors and journalists.

2) Energy – incorporate high performance energy sources to support the economy

New Technologies and Energies Hub (new in 2024): an area dedicated to exhibitors and start-ups, and a speaking platform; a demonstration zone dedicated to equipment, in particular electric, for a plunge into the worksite of the future, with two exhibitors already registered: Theam and River.

3) New Equations – promote professions, and financial and human resources

A space dedicated to jobs and training to give a platform to occupational promotion initiatives, workshops and talks, job dating sessions, etc. INTERMAT Rental Day: a special day devoted to equipment rental with contributions from international experts.

4) Commitments – reach net zero to contribute to protecting the planet

An exhibition model redesigned in terms of offering and format (four days instead of six); a show redesigned in an approach of resource sobriety and circular economy, with responsible products and services; an event offering physical and social access to the widest possible audience.

There will also be an exhibitor range revolving around five hubs of expertise:

  • Earthmoving, demolition and transportation;
  • Roads, materials and foundations;
  • Lifting and handling;
  • Building, civil engineering and concrete sector, including the event WOCE which will present the full value chain of the concrete industry from upstream to downstream;
  • New in 2024: New Technologies and Energies (electric, hydrogen, natural gas energies, autonomous vehicles, virtual technology engineering, etc.).

During the four days of the show, professionals will be able to take advantage of the demonstration zone, an integral part of the INTERMAT DNA, which will offer centre stage to innovative equipment operating in real-life conditions.

Australia’s first Liebherr R 9300 mining excavator starts work at Karlawinda gold mine

Liebherr-Australia has recently delivered an R 9300 mining excavator to long-term customer MACA at the Karlawinda gold project, in Western Australia, with the machine becoming the first such excavator commissioned in the country.

After a successful launch – with five of these excavators already sold in Indonesia – the commissioning of the first R 9300 in Australia further demonstrates the strength of the machine’s reputation, the OEM says.

The mining excavator was commissioned in late August at Karlawinda, in the Pilbara region of Western Australia. MACA, a global contractor that works within the mining, construction and process engineering sectors and is owned by Thiess, is excited to welcome this machine to its growing Liebherr excavator fleet, it says.

It joins three Liebherr R 9200 excavators operating on the site, owned by Capricorn Metals, expanding MACA’s already extensive Liebherr fleet, totalling over 20 excavators.

The R 9300 was chosen not only for its capacity to assist in meeting the production targets of its client, but also for the excavator’s fuel efficiency; its state-of-the-art technology, such as Liebherr’s Assistance Systems; and its operational effectiveness, Liebherr says.

Liebherr-Australia completed the assembly, testing and commissioning of the R 9300 in a matter of four weeks. The company will continue to support the machine and MACA from both its Perth and Newman branches, as well as from the factory for Liebherr mining excavators in Colmar, France.

The R 9300 was launched to the global mining market in June of this year. It is the second Generation 8 excavator within the Liebherr Mining portfolio and comes with the most advanced Liebherr Mining innovations as standard. The R 9300 will replace the R 9250 as the 250-tonne mining excavator in Liebherr’s portfolio in 2024.

You can find out more about the R 9300 in this video interview here.

Fortescue kicks off battery-electric truck testing in the Pilbara

Fortescue Metals Group has started testing a battery-electric truck at its operations in the Pilbara of Western Australia as part of its latest decarbonisation efforts.

Having floated the idea of a battery-electric haul truck some three years ago – and started a physical build process 12 months ago – the company is now testing a battery-electric converted MT4400 AC truck at its Christmas Creek iron ore operations, Fortescue confirmed last week.

WAE and Fortescue Future Industries, part of Fortescue’s newly branded Fortescue Energy division, have been spearheading developments on this truck, referred to as the “Roadrunner” (pictured). The 221-t payload vehicle is fitted with a 1.4 MWh battery from WAE. It has already been run through more than 20 hours of dynamic testing that has included, among other things, downhill recharging scenarios, Fortescue said last week.

The vehicle is thought to be the largest battery-electric haul truck running in Pilbara operating conditions.

The converted MT4400 AC is expected to be joined by a 3 MW charger prototype – developed by WAE and a third party – by the end of the year. “This will help us to understand and develop haul truck duty and charging cycles,” Mark Hutchinson, CEO of Fortescue Future Industries, said in a conference call last week.

In June, Fortescue, through WAE, announced the expansion of its battery and electric powertrain production operations in the UK with an additional state-of-the-art facility in Oxfordshire. The facility, which will open in 2024, will focus on the production of a wide range of zero emission products for the off-road sector, including trucks and trains.

Alongside these battery-electric developments, Fortescue said it will have its first “green hydrogen fuel cell haul truck” on site for similar testing next year. This truck is being delivered through the company’s partnership with Liebherr and will be based off a 240-t-payload T 264 haul truck.

In June 2022, Fortescue announced a partnership with Liebherr for the development and supply of green mining haul trucks for integration with the “zero emissions power system” technologies being developed by FFI and WAE. Under the partnership, Fortescue agreed to purchase a fleet of 120 haul trucks from Liebherr; a commitment that represents approximately 45% of the current haul truck fleet at Fortescue’s operations.

In answer to an analyst question last week, Christiaan Heyning, FFI’s Head of Decarbonisation, said: “We are…putting both battery-electric trucks as well as a fuel cell electric trucks on-site this calendar year to do extended testing to figure out the ramp-up efficiency of both battery-electric and fuel cell. We will use those insights to make the final decisions about what our fleet will be.

“As you appreciate, it’s really dependent on whole routes and, therefore, we need to do more testing before we can make up our mind.”

A 100-day “sprint” FFI project focused on converting a legacy 221-t class Terex Unit Rig MT4400 AC electric drive, diesel-powered haul truck to run on a ‘green’ hydrogen 180 kW fuel cell system and a 300 kW/h battery was previously completed and run at Fortescue’s Hazelmere facility in Western Australia.

First Quantum to add to Liebherr T 284 fleet at Sentinel copper mine

First Quantum Minerals is in the process of bolstering its fleet of Liebherr T 284 trucks at the Sentinel operation in Zambia, in line with a redistribution of loading equipment to better suit working areas at the copper mine.

In the company’s March quarter, Sentinel reported copper production of 36,232 t, 37,177 t lower than the previous quarter due to the intense rainy season, resulting in the accumulation of water in the Stage 1 pit.

Saturated ground conditions significantly impacted mining rates due to poor road conditions and water in the pit prevented access to working faces, particularly in the lower benches of Stage 1, First Quantum said in its March quarter results.

Despite the challenges encountered during this quarter, copper production for 2023 remains unchanged at 260,000-280,000 t as higher feed grades are expected in the second half of the year, with grades showing improvement already in April.

“The current focus on deploying additional dewatering capacity in Stage 1 to regain access to the high-grade ore is already yielding results early in the second (June) quarter,” it said.

The mine plan has been rescheduled, even if total volumes remain substantively the same and higher grade zones will be dispatched across the remaining three quarters of the year, the company noted. This is to be complemented by a change in location of the in-pit ramps to liberate high-grade ore by mining the saddle zones between Stage 1 and Stage 2.

There will also be a redistribution of loading equipment to better suit working areas and truck fleet capacity is planned to increase in the June quarter with the commissioning of an additional Liebherr T 284, followed by two more in the second half of the year.

Sentinel is a leader in electric mining as a long-term user of trolley assist technology with its Komatsu 960E and Liebherr T 284 trucks, which run under trolley using pantographs.

At MINExpo 2021, Liebherr confirmed it would supply a further 11 T 284 trucks to operate on trolley lines at First Quantum Minerals’ Sentinel and Cobre Panama mines with the miner claiming, in the process, the title of the world’s largest ultra-class truck fleet on trolley. Three of these 363-t-payload machines were planned to be deployed at Sentinel, with the remainder at Cobre Panama.

Two Liebherr T 284 trucks with the Trolley Assist System were commissioned at Sentinel copper mine all the way back in 2016 and testing of the trolley solution began in February of 2017, with 12 months allotted for FQM to evaluate the trucks, the trolley and the customer service.

At the end of the trial period, FQM expressed it was pleased with the results of the Trolley Assist System and the performance of the T 284, leading to an order for six more trolley-capable T 284 trucks at Sentinel mine, along with 30-trolley-capable T 284 trucks for Cobre Panama copper mine in Panama, Liebherr explained.

Williams Advanced Engineering to debut off-highway electrification solutions at Bauma

Williams Advanced Engineering (WAE), now wholly owned by Fortescue Metals Group, will be showcasing a wide range of cutting-edge electrification solutions, all of which will support acceleration of the off-highway sector in its journey to decarbonisation, at next week’s Bauma 2022 event in Munich, Germany.

WAE will be using the event to show its leading advanced battery and energy storage technology, which have been specifically developed for the rugged use cases of mining and other off-highway applications.

Following its acquisition by Fortescue at the start of this year, WAE, already a leader in high performance battery technology developed originally for global motorsport and road car programs, is becoming a leading supplier to the off-highway sector, using its expertise to support Fortescue in its transition to a global green renewables and resources company through the decarbonisation of its worldwide vehicle fleet, it said.

Additionally, WAE is working on a world first, zero emission ‘Infinity Train’; a regenerating battery-electric iron ore train project using gravitational energy to recharge its battery-electric systems without any additional charging requirements for the return trip to reload.

In June 2022, Fortescue announced a partnership with Liebherr, who will be developing and supplying green mining haul trucks (using the T264) in which zero emission power system technologies – developed by Williams Advanced Engineering – will be integrated.

WAE’s technology line-up at Bauma 2022 will include the following off-highway specific innovations:

Off-Highway Battery Module

Featuring a scalable, modular design delivering sub-30 minute pack charge times for maximum performance, WAE’s Off-Highway Battery Module boasts laser-welded cell-to-busbar technology for in service reliability, the company says. It also has a robust alloy frame, which improves durability and extends life in service, as well as optimised cell packaging for maximum energy density.

Battery Management Unit

Unlocking battery performance through best-in-class software architecture, WAE’s Battery Management Unit is designed for pack architectures of less than 800 V. Its advanced state detection algorithms allow for more efficient energy usage, while the unit also reduces equipment down-time by enabling maximised fast charge rates.

Cell Management Unit

Enabling real-time telematics to maximise cell performance, WAE’s Cell Management Unit allows high precision cell voltage and temperature monitoring. Its innovative flexi interconnects enables enhanced durability, while the system’s design also allows manufacturing complexity to be reduced for high volume applications.

DC-DC Converter

With a ruggedised design developed for deployment in off-highway vehicle applications, WAE’s DC-DC Converter is a 600kW 1.5kV – 1kV stepdown converter for high power loads. Its Silicon Carbide technology delivers exceptional efficiency of 98.5%, while full power operation takes place at ambient temperature of 50°C.

Vehicle Control Module

This powerful processing platform unlocks vehicle performance advantages, featuring a versatile vehicle system controller. Specifically designed for decarbonised powertrains it has a flexible heterogenous MPSoC processor.

Graham Belgum, General Manager for Green Fleet, WAE, said: “High performance battery and electrification systems are at the core of what we do. Over the last two decades WAE has garnered unparalleled experience in the development of cutting-edge technology which, increasingly is being applied to the off-highway sector. Now that we are part of the Fortescue family, WAE is central to battery power systems and products capability, supporting the business as it transitions to a clean, green fleet. Our technology has the potential to accelerate the decarbonisation of any off-highway vehicle – and we are delighted to be debuting these at Bauma 2022.”

WAE putting Fortescue in mine electrification pole position

Andrew Forrest’s statement on Fortescue Metals Group’s planned acquisition of Williams Advanced Engineering (WAE), an offshoot of the Williams F1 team founded by the revered, late Sir Frank Williams CBE, back in January was hardly understated.

He said: “This announcement is the key to unlocking the formula for removing fossil fuel powered machinery and replacing it with zero carbon emission technology, powered by FFI (Fortescue Future Industries) green electricity, green hydrogen and green ammonia.”

As time has progressed, the £164 million ($193 million) deal for the UK-based WAE closed (in March), and another significant announcement in the form of a tie-up between FMG, FFI, WAE and Liebherr has followed, the FMG Founder and Chairman’s words have looked increasingly prescient.

This became apparent to IM on a recent visit to WAE’s Grove headquarters in Oxfordshire, England.

What FMG now has on its books and what FFI is managing in the form of WAE is arguably one of the world’s leading decarbonisation technology companies.

WAE’s reach goes far beyond the pit lanes of a race track. Its impact is felt in the automotive, defence, aerospace, energy, life sciences and health care sectors – as an example, a Babypod 20, a Formula One-inspired environment for new-born babies in need of emergency transportation, was on display in the boardroom IM sat in during an interview at Grove.

One of its more recent market entries has been in mining, with WAE’s fingerprints on two of the industry’s major fuel cell electric vehicle (FCEV) haul truck movements.

Prior to the acquisition by Fortescue, WAE provided “electrical architecture and control hardware and software” for the battery system on a 100-day “sprint” FFI project focused on converting a legacy 221-t class Terex Unit Rig MT4400 AC electric drive, diesel-powered haul truck to run on a ‘green’ hydrogen 180 kW fuel cell system and a 300 kW/h battery.

For the nuGen FCEV truck that premiered at Anglo American’s Mogalakwena PGM mine in South Africa earlier this year, WAE supplied a 1.2 MWh battery pack that, along with multiple fuel cells amounting to 800 kW of power, propelled the converted 291-t-class Komatsu 930E around the mine site.

Input to these two projects put WAE on the mining map, but this represents a fraction of the impact the company is likely to have on mining’s decarbonisation journey going forward.

WAE is currently engaged on two major projects for FFI – one being the conversion of another legacy Terex MT4400 AC electric-drive truck to an all-battery powered setup and the other being an all-battery rail loco that FFI has named the INFINITY TRAIN™.

Both projects highlight the depth of battery system technology expertise that led FMG to acquiring the company in the first place – design expertise spawned from development across multiple sectors and operating environments, utilising the latest cell technology across all form factors.

There is a common thread that hangs between all this work, as Craig Wilson, WAE CEO, explained to IM.

“We develop our battery systems for the specific application, factoring in the duty cycle, the cost constraints, required performance and environment the solution will be working in,” he said. “In motorsport, for instance, you can imagine weight, aerodynamics and space are more critical than they are in mining.”

Being battery cell, chemistry and format agnostic, WAE has built up a reputation in the battery industry for specifying and developing a diverse pool of battery systems that continue to push performance to the limit.

Differentiated modelling

Sophisticated modelling and simulation tools – much of which has been developed in-house – are behind this, according to WAE’s Chief Programme Manager, Alec Patterson.

“We have detailed in-house simulation tools which allow us to develop and optimise a battery pack’s performance against any customer’s drive cycle criteria,” he said. “This includes thermal simulation where the team model the detailed internals of a cell, allowing them to understand exactly how each cell is likely to behave and, thereby, being able to optimise their cooling for increased performance. This comes from our motorsport heritage and the team’s ability to manipulate and analyse large amounts of data through supercomputer levels of processing power.”

Prototyping and field tests are designed to “validate” this modelling and simulation work, he added.

Battery design also calls for a strong focus on safety and this is where WAE’s extensive practical experience is fully utilised.

“We have detailed in-house simulation tools which allow us to develop and optimise a battery pack’s performance against any customer’s drive cycle criteria,” Alec Patterson says

Patterson summarised this offering: “There are a number of ways the battery is developed to ensure cell safety. These range from understanding in detail the performance of the cell through practical testing, the design of the modules themselves and the monitoring of the cells for voltage and temperature throughout usage. WAE has developed its own Cell Monitoring Unit hardware and Battery Management Unit hardware and, combined, they monitor the status of the pack and control the performance outputs many times a second. In the FFI battery sub pack, dielectric (non-conductive) coolant is used so if a leak was to occur it wouldn’t cause an internal issue; detection of which would be through WAE’s propriety on-board sensors.”

Overlay these preventative measures with an array of experience in various fields that would have seen battery systems take significant G-shock loads and operate in high temperature environments – whether that be a crash on a Formula E circuit or an Extreme E race in the Sahara – and it is easy to see why FMG initially believed WAE had knowledge and skills transferrable to mining.

Patterson concludes that advances in quality within the manufacturing process will also add to the reliability of the sub packs. At WAE those advances come in the form of laser welding, which ensures each cell is connected robustly for maximum performance.

Battery prototype progress

All this and more are being factored into the 221-t all-battery solution WAE is currently focused on as part of the FFI and FMG brief.

The battery will take the place of the diesel engine and alternator and will plug directly into the Terex MT4400 inverter to drive the motors and rear wheels. The battery system will have a capacity of >1 MWh (final specification to be revealed at a later date) and will be charged by a “fast-charge solution” sourcing power from a renewable grid FMG has already setup as part of its 60 MW Chichester Solar Gas Hybrid Project.

FMG has already set up a renewable grid as part of its 60 MW Chichester Solar Gas Hybrid Project

Once the battery system is delivered, integrated into the truck and commissioned at FFI’s Hazelmere facility, it will be transported to the Pilbara where it will start extensive testing outside FMG’s current mining operations.

WAE, FMG and FFI have overcome more than a few hurdles to get to the point where they can talk about such a plan.

While most of the battery houses in the UK can test each sub pack individually, WAE had to locate a specialist test house capable of testing out the full battery pack from both a motor-drive perspective and a battery re-generation standpoint.

This has seen the complete solution – a 12 t motor, inverter, cooling system, battery system and power distribution unit – begin testing a few months back.

Charging packs of this scale is one of the major industry challenges currently.

“Our charging strategy is centred around the individual cell chemistry and form factor which allows us to specify a higher rate of charge for the battery sub pack,” Patterson said. “To enable fast charging, a combination of a large charger and ability to cool the pack through the charging process is required, and our pack is designed for both.”

At the same time, WAE is aiming to further optimise the regeneration aspect of the electrification project, realising this is key to getting the trucks to complete as many haul cycles as possible without the downtime associated with a battery recharge – even if it is a ‘fast charge’.

“The real challenge is centred around how to manage the large accumulation of energy from the wheel motor during braking or retarding downhill fully laden,” Patterson said. “Do you send this to the battery or the resistor grid to burn off? Our job is to optimise the power electronics to make sure as much of that energy as possible goes back into the battery in order to make the whole system more efficient.”

The entire battery system will soon be shipped to Australia to go into the Terex truck at Hazelmere, at which point the charging system can be fully tested and the re-generation system trialled.

Leveraging gravity

This work will no doubt influence the other big project WAE is currently involved in for FFI and FMG – the electrification of FMG’s rail operations.

Fortescue’s current rail operations include 54 operating locomotives that haul 16 train sets, together with other on-track mobile equipment. Each train set is about 2.8 km in length and has the capacity to haul 34,404 t of iron ore in 244 ore cars.

A world first, zero emission INFINITY TRAIN concept has been put forward to replace this setup – which travels on some 620 km of track between the Cloudbreak mine and Herb Elliott Port at Port Hedland.

The regenerating battery-electric iron ore train project will use gravitational energy to fully recharge its battery-electric systems without any additional charging requirements for the return trip to reload, according to FMG.

The challenges associated with this project include the size of the battery and motor combination required to store enough energy from the fully laden, downhill journey from Cloudbreak to Herb Elliott Port to make sure the unladen trains can travel back without a charge, and the residual power and torque generation that would typically be applied to get the locos started.

On the latter, Patterson said: “Your contact area in terms of the wheel to rail is very small in comparison to the load, so our control strategy will utilise learning from our in-house VDC (vehicle dynamic control) software to design a solution that controls slippage for maximum adhesion.”

If an appropriate solution comes to the fore, the sustainable value is significant for FMG.

Fortescue’s rail operations consumed 82 million litres of diesel in the 2021 financial year, accounting for 11% of Fortescue’s Scope 1 emissions. This diesel consumption and associated emissions will be eliminated once the INFINITY TRAIN is fully implemented across Fortescue’s operations, significantly contributing to Fortescue’s target to achieve “real zero” terrestrial emissions (Scope 1 and 2) across its iron ore operations by 2030.

Electrification for everyone

Just as WAE’s involvement in the conception of the first Formula E battery led to wider electrification in motorsport, WAE believes its work in mining will have far-reaching ramifications across the off-highway sector.

Just how far reaching it will be is dictated by the most significant project – in terms of scale and timeline – WAE has on its books.

In June, FMG announced a partnership with Liebherr for the development and supply of green mining haul trucks for integration with the “zero emissions power system” technologies being developed by FFI and WAE.

Under the partnership, Fortescue will purchase a fleet of haul trucks from Liebherr; a commitment that represents approximately 45% of the current haul truck fleet at Fortescue’s operations, with truck haulage diesel consumption representing approximately 200 million litres in the 2021 financial year, accounting for 26% of Fortescue’s Scope 1 emissions.

The zero emissions power system technologies are expected to be fitted on machines based off the 240-t T 264 model to be deployed at its Pilbara mining operations. They could include both battery-electric and FCEV configurations, hence the reason why the all-battery prototype project and the FCEV project are so significant.

With the first of the zero emission haul truck units expected to be fully operational within Fortescue mine sites by 2025, FMG, WAE and Liebherr look set to take the electrification lead over its mining company peers.

Yet Wilson says this type of solution could turn into a commercial product that others select for their own decarbonisation program – hence the industry-wide electrification potential.

When asked the question whether the company may still supply battery systems to the likes of Anglo American (as it did for the NuGen truck) under the new Fortescue ownership, he replied: “We could do, but the decision is not just down to us.

“Through the relationship with Liebherr, the intention is to provide really competitive products that are available to other mining companies, whether it be Anglo, Vale or BHP, for example…The absolute intention is not to come up with a development or product that is just for Fortescue.”

In this respect, he likens FMG to Tesla in the way the electric car manufacturer has acted as the catalyst to fundamentally change the automotive sector’s electrification approach.

“Tesla, today, is nowhere near being considered a large automotive manufacturer by industry standards, but they have created a catalyst for everybody else to move from in terms of battery-powered cars,” Wilson said.

“They have almost coerced the rest of the manufacturers to move this way; you only need to look at VW Group now – one of the world’s largest car makers – that is committing the majority of its business towards electrification.

“The difference with Fortescue is it is both the operator of these vehicles as well as the owner of the technology (through WAE). It is developing these products to use them, putting its whole business on the line.”

This extends as far as looking at its own mining operations and how it can optimise the pit profile and infrastructure to benefit from all the advantages expected to come with battery-electric haulage.

“Both the Fortescue mine planning and decarbonisation teams are working hand-in-hand with us to develop a mine site for the future of electric mining,” Patterson said. “We are working together to answer the questions about what needs to change to operate these trucks to maximise uptime, where to put the charging points, how to optimise the charging, etc.

“That work is going to be really important for us in terms of developing a commercial solution that provides the sustainable gains over the long term and decarbonises the entire fleet.”

Even when factoring in a project that takes ‘stretch targets’ to a new level, that is reliant on sourcing components from an evolving electrification supply chain, and that is scheduled to see solutions arrive within three years of finding an OEM partner in the form of Liebherr, it’s hard to doubt WAE, FMG, FFI and (of course) Andrew Forrest from steering such a project through to the finish line.

After that, it’s a matter of the rest of the industry catching up.

Fortescue pledges $6.2bn of decarbonisation investment on way to producing carbon-free iron ore

Fortescue Metals Group’s decarbonisation plans have stepped up a gear, with the company announcing it intends to eliminate fossil fuel use and achieve “real zero” terrestrial emissions (Scope 1 and 2) across its iron ore operations by 2030 with a $6.2 billion capital investment.

The investment, the company says, will eliminate Fortescue’s fossil fuel risk profile and enable it to supply its customers with a “carbon-free” product.

“Real zero” refers to no fossil fuels and, wherever possible, no offsets, the company explained. Under the use of the term, offsets must only be used as a temporary solution while the technology or innovation required to completely decarbonise is developed.

Fortescue’s strategy will see the company lead the market in terms of its response to growing customer, community and investor expectations to reduce/eliminate carbon emissions, it said.

“Fortescue expects to generate attractive economic returns from its investment arising from the operating cost savings due to the elimination of diesel, natural gas, and carbon offset purchases from its supply chain,” it added. “Fortescue is well positioned to capitalise on first-mover advantage and the ability to commercialise decarbonisation technologies.”

Fortescue made the announcement at the invitation of US President Biden’s First Movers Coalition and the United Nations Global Compact, with the Secretary General of the United Nations at the CEO roundtable on “Business leadership to rescue the Sustainable Development Goals”.

Fortescue also announced that the Science Based Targets Initiative (SBTi) will verify and audit its emissions reduction. This technical auditing initiative was instituted to ensure companies reach their Paris Agreement goal to limit global warming to 1.5 degrees centigrade.

Fortescue says its decarbonisation journey started on the commencement of the first major trip on August 25, 2020, during the advent of COVID-19 to secure technology, demand and resources for the green energy ecosystem. It consolidated further at the successful completion of the 100-day sprint to create the world’s first mining truck to run on hydrogen (a FCEV).

When fully implemented, Fortescue’s decarbonisation strategy and associated investment will provide significant environmental and economic returns by 2030, including:

  • Avoidance of 3 Mt of CO2-equivalent emissions per year;
  • Net operating cost savings of $818 million per year from 2030, at prevailing market prices of diesel, gas and Australian Carbon Credit Units (ACCUs);
  • Cumulative operating cost savings of $3 billion by 2030 and payback of capital by 2034, at prevailing market prices;
  • Elimination of Fortescue’s exposure to fossil fuels and associated fossil fuel price volatility which, in turn, will de-risk the operating cost profile;
  • Removal of the company’s exposure to price risks associated with relying on carbon offsets as well as carbon tax regulatory risk;
  • Establish a significant new green growth opportunity by producing a carbon-free iron ore product and through the commercialisation of decarbonisation technologies;
  • Ensuring future access to green driven capital markets.

Fortescue’s capital estimate of $6.2 billion is expected to see the investment largely planned in the company’s 2024-2028 financial years. This investment includes the deployment of an additional 2-3 GW of renewable energy generation and battery storage and the estimated incremental costs associated with a green mining fleet and locomotives.

The capital expenditure to purchase the fleet will be aligned with the scheduled asset replacement life cycle and included in Fortescue’s sustaining capital expenditure. Studies are underway to optimise the localised wind and solar resources.

The investment is expected to generate a positive net present value through enabling the displacement of approximately 700 million litres of diesel and 15 million GJ of gas per year by 2030, as well as the associated reduction in CO 2 emissions.

Fortescue Executive Chairman, Dr Andrew Forrest AO, said: “There’s no doubt that the energy landscape has changed dramatically over the past two years and this change has accelerated since Russia invaded Ukraine.

“We are already seeing direct benefits of the transition away from fossil fuels – we avoided 78 million litres of diesel usage at our Chichester Hub in financial year 2022 – but we must accelerate our transition to the post fossil fuel era, driving global scale industrial change as climate change continues to worsen. It will also protect our cost base, enhance our margins and set an example that a post fossil fuel era is good commercial, common sense.

“Fortescue, FFI and FMG are moving at speed to transition into a global green metals, minerals, energy and technology company, capable of delivering not just green iron ore but also the minerals, knowledge and technology critical to the energy transition.

“Consistent with Fortescue’s disciplined approach to capital allocation, this investment in renewable energy and decarbonisation is expected to generate attractive economic returns for our shareholders through energy cost savings and a sharp reduction in carbon offset purchases, together with a lower risk cost profile and improvement in the integrity of our assets.”

Fortescue has already made significant effort in decarbonising its iron ore operations through its successful green fleet trials and innovation, acquisition of Williams Advanced Engineering (WAE) and its partnership with Liebherr in June this year. Building on Fortescue’s announcement in March 2022 to develop with FFI and WAE the world’s first regenerating battery electric iron ore train, feasibility studies are progressing, with delivery of the first parabolic (gravity powered) drive trains to the Infinity locomotives scheduled to be operational by the end of 2026.

Liebherr-Australia prepares for zero emission tech developments with Perth facility expansion

Liebherr-Australia has expanded its Perth mining facility, adding 47,000 sq.m of workshop, office and build space to the complex, strengthening the company’s ability to deliver accelerated zero emission solutions to the wider market.

Perth is Liebherr-Australia’s second largest branch after the company’s head office in Adelaide, South Australia.

Liebherr says the company’s growing involvement in the development and implementation of zero emission technology with Australian customers illustrates the necessity for this investment in infrastructure, and signifies Liebherr’s commitment to these industry-leading projects.

The Redcliffe-based branch purchased the land and buildings adjacent to the current location, increasing the Liebherr complex from 34,000 sq.m to 81,000 sq.m. The new acquisition includes two workshops and a three-storey office building, adding to Liebherr’s existing 3,000 sq.m service workshop, 5,000 sq.m parts warehouse, along with an administration building and build area.

Liebherr-Australia Managing Director, Trent Wehr, said: “This is our largest investment in infrastructure here in Australia in many years, and this signifies how vital this facility is for our current and future business. Liebherr’s developments in zero emission technology, and the projects we are working on with industry partners and customers, are progressing every day and will deliver tangible solutions for the wider industry well before 2030.

“The team at Liebherr-Australia is making important contributions to the decarbonisation of the mining industry, and we’re committed to resourcing this momentous work for both our long-term success and the benefit of the whole industry.”

The newly acquired office and workshop buildings will form the central hub for Liebherr’s mining zero emission, autonomy and other technology development and implementation projects in Australia.

The workshop and additional hardstand areas will facilitate these development projects, as well as new equipment builds for the growing number of machine orders in Western Australia. The additional office space will house the growing teams working on these industry-leading projects.

One can expect some of the work associated with integrating the zero emission power system technologies being developed by Fortescue Future Industries and Williams Advanced Engineering into Liebherr’s 240-t-class T 264 haul truck as part of an agreement with Fortescue Metals Group to be carried out at these expanded facilities.

Liebherr-Australia’s Regional Manager WA, Paul Hyham, says the company’s decarbonisation and technology focus has ramped up quickly over the past year.

“We’re building a really critical team here in Perth to support new technology development, which will employ everyone from engineers to on-site technicians,” he said. “We’re excited to be bringing across some of our best international talent, as well as recruiting talent locally, and upskilling our own workforce over the next 12 months. We currently have around 200 permanent employees here in Perth and we forecast an increase steadily over the next few years.”

This expansion will have significant impact on the Liebherr Mining business both locally and globally.

Hyham continued: “It’s exciting to have the forefront of this technology development and deployment right here in our backyard. Across the business there’s a feeling of excitement that we’re making real progress. Announcements like this facility expansion really show our employees, customers and our wider network that we’re on the cusp of meaningful change.”

Alongside this expansion, the Perth complex will continue to be the main mining facility for all services in Western Australia, and support its satellite network of branches in the state’s regional mining hubs including Newman and the recently-established branch in Kalgoorlie.
