BHP's first electric excavator operational at Yandi

21 August 2024

BHP has taken another important step on our operational decarbonisation journey with the first electric excavator in BHP’s fleet now operational at our Yandi iron ore mine in the Pilbara, Western Australia.

Instead of a diesel engine, the R 9400 E Liebherr electric excavator has an electric motor, with power fed to the machine by a trailing cable.

Equipped with Liebherr's autonomous cable reeler for optimal on-site mobility, this innovation boosts productivity and operator safety.

Western Australia Iron Ore (WAIO) Asset President Tim Day said reducing diesel in our business was key to helping us achieve our medium-term target to reduce operational greenhouse gas (GHG) emissions (Scopes 1 and 2 from our operated assets) by at least 30 per cent by FY2030 (from adjusted FY2020 levels) – and ultimately our long-term goal of net zero operational GHG emissions by CY2050.

“Electrification of our fleet is our preferred solution to displace greenhouse gas emissions from using diesel – from trucks to trains to excavators – we’re working hard to electrify our equipment,” Tim said.

“Collaborations with partners like Liebherr are critical to accelerate development of the technology required to reduce diesel emissions, while ensuring we continue to improve the safety and productivity of our operations.”

Brian Boitano, Executive General Manager, Sales and Marketing, Liebherr-Australia said: “The R 9400 E is a testament to Liebherr’s dedication to providing innovative and efficient zero emission solutions for the mining sector.

“We are thrilled to partner with BHP, a forward-thinking industry leader, to introduce our proven electric excavators into their operations and to help them move forward in their decarbonisation journey.”

This milestone not only underscores BHP's commitment to adopting cutting-edge technologies but also highlights Liebherr's role as a trusted partner and solutions provider within the mining sector.

Our strategy aims to decarbonise our mining equipment by switching from diesel to renewable electricity or other low to zero GHG emissions power. Renewable electricity is not purchased through the market as WAIO is not connected to an existing grid, so we are working through the best way to introduce the large volumes of renewable or other low to zero emissions power that we will need.   

This includes a number of actions to decarbonise our sites, with a focus on maximising renewable electricity and other sources of low to zero GHG emissions power, diesel displacement through electrification, and working to manage fugitive methane emissions.

les expérimentations vont laisser place à l'industrialisation :

Fortescue, Liebherr secure orders for 100 electric mining trucks

Australian miner Fortescue and German-Swiss equipment manufacturer Liebherr have secured orders for 100 autonomous battery-powered mining trucks for other mining and transport companies, Fortescue executive chairman Andrew Forrest told Reuters.

The trucks were developed as part of Forrest’s plan to cut Fortescue’s direct and indirect carbon emissions to zero by 2030. Fortescue is the world’s fourth-largest iron ore miner.

Fortescue and Liebherr have received expressions of interest for hundreds more of the electric version of the T 264 truck that they developed together, Forrest told Reuters in an interview in New York.

The 240-tonne capacity trucks are more expensive than the roughly $5 million price tag for large diesel mining trucks. Fortescue and Liebherr, which teamed up in 2022 to develop the trucks, have not detailed the price of the electric version.

The two companies signed a $2.8 billion partnership on Wednesday to supply 360 of the trucks to Fortescue, three times as many as the 120 planned under the initial partnership. They would also supply 55 electric excavators and 60 battery-powered dozers. The vehicles they have developed would be made available for other firms, the companies said on Wednesday.

Fortescue builds the drive trains and batteries, which it developed, while Liebherr provides the truck, Forrest said.

“They are more reliable and more productive than diesel trucks,” he said.

“That’s our holy grail, that we can take on the fossil fuel trucks with our first edition. That’s not a bad outcome. Immediately competitive.”

The company has also developed a way to fully charge the huge trucks in 30 minutes, he said. The technology was scaled up from the technology used to charge electronic racing cars used in Formula E, he said.

Fortescue is saving $300 million to $400 million per year on fuel costs already from battery-powered trucks in its fleet, Forrest said.

Fuel and energy costs are the biggest operating costs for Fortescue, he said. Eliminating some of those costs would help the company weather structural changes in the iron ore market, he said.

Iron ore prices are hovering near two-year lows plumbed earlier this month around $91 a tonne as more supply comes on line amid top buyer China’s economic slowdown.

Fuel is also one of the company’s biggest emissions sources. Fortescue’s mining fleet consumed about 450 million litres of diesel in FY24, accounting for 51% of its scope 1 carbon emissions.

Fortescue has been exploring various strategies to produce green iron metal. The company eventually wants to convert all its iron ore into green iron, Forrest said, declining to say when it might meet that target.

There would be strong demand for green iron from steel plants in China, Japan, South Korea and Europe, he said.

“They’ll take it straight away,” he said. “As they can make steel without the pollution.”

Electric mines to operate with 56-88% less costs than diesel
Electric Mine Consortium’s report states that electric mines are set to operate at significantly lower costs but present challenges such as infrastructure and upfront costs.

Smruthi Nadig September 30, 2024

The mining industry is at a turning point, with electric mines able to operate at significantly lower costs, between 56% and 88% less than those powered by diesel, according to a report by the Electric Mine Consortium (EMC).

More than 80% of publicly traded companies in the industry have committed to achieving net-zero emissions by 2050. Approximately 25% have also set near-term 2030 or 2035 carbon reduction targets.

The report reveals that 84% of industry professionals believe Australia’s mining sector will not reach the government’s 82% renewable energy penetration target by 2030.

The mining industry is accountable for around 8% of global carbon emissions. However, only 60% of the industry plans to switch its upcoming mining operations to electric. Around three-quarters of miners cite high capital costs as the primary barrier to adopting electric equipment, rated 1.5 times more significant than concerns about operational effectiveness.

The price of new battery-electric haul equipment can be double that of diesel. EMC states that the business model carries operational risks and uncertainty. The associated infrastructure such as upgraded electrical systems, fast chargers and spare batteries is also a new addition that increases costs.

However, equipment will keep getting better and cheaper. For example, Sandvik’s latest battery will have a 36% longer range than its previous iteration.

The report indicates that electric equipment, clean energy, ventilation, drilling and processing will all operate on the same energy system. Any extra energy used by electric equipment will be offset by reductions in ventilation system energy use, as explained in the IGO, Perenti and ABB Electric Mine white paper based on the Cosmos mine.

Mark Norwell, CEO of Perenti, recently collaborated with IGO and its business partner ABB to study the transition of an underground mine’s fleet from diesel vehicles to battery-electric vehicles, emphasising the importance of all stakeholders in mine electrification.

Norwell said: “We are optimistic that in time an electric underground mine will be the most economic and socially responsible mining method. The electrification of underground mines will deliver significant benefits to health, environment and cost.”

As of 2024, the financial case for using total cost of ownership or net present value is weak in Australia but more favourable in Canada and Europe due to public policies.

According to the report, more than 15% of Sweden’s Sandvik’s global production and demand is now for battery-electric load and haul equipment, but in Australia, no battery-electric underground haul trucks have been ordered for full operation due to “a lack of policy support”.

Nonetheless, global mine health and safety laws require operators to minimise risks while considering costs. Implementing a single electric energy system can accelerate the development of technologies like automation, improving safety for underground workers.

“With diesel particulates posing severe health risks such as lung cancer, and with current Australian standards being over 6x higher than [the] level considered safe by Safe Work Australia for underground miners, electrification is not just an economic opportunity; it is a health imperative,” stated Graeme Stanway, chair of the Electric Mine Consortium. “Investing in cleaner technologies can eliminate these hazards and support our commitment to sustainability.”

Le plan de Fortescue pour faire passer la mine électrique à l’échelle industrielle… en misant sur les batteries

Le groupe australien Fortescue, dirigé par le milliardaire Andrew Forrest, veut faire un pas de géant vers la mine verte. Pour «arrêter de brûler des combustibles fossiles» dès 2030, le géant des mines de fer a notamment signé pour 2,8 milliards de dollars de contrats avec l'allemand Liebherr pour s'équiper en excavateurs, tombereaux et autres engins électriques alimentés avec des batteries.

Nathan Mann 11 octobre 2024


Pour diminuer sa consommation de diesel, Fortescue prévoit d'utiliser des engins à batteries, mais aussi une cinquantaine d'excavateurs électriques.

«Le Net Zero en 2050 est une arnaque. Le monde a besoin d’un Vrai Zero maintenant. Fortescue peut vous dire quand nous allons éliminer les combustibles fossiles et vous montrer exactement comment. Tout industriel devrait en faire autant que nous» ! C’est avec un certain sens de l’urgence et de la provocation médiatique que le milliardaire australien Andrew Forrest a dévoilé, le 25 septembre dernier, le plan de transition climatique de Fortescue. Il préside cette entreprise qu’il a fait grimper parmi les plus grands producteurs de minerai fer du monde (192 millions de tonnes exportées et 10 milliards de dollars américains de profits avant intérêts, taxes et amortissement en 2023).

Gold mining company Newmont has commissioned its first battery-electric large mining truck, dubbed Early Learner Cat 793 XE, at its CC&V mine in Teller County, Colorado.

This initiative is part of Newmont’s strategic alliance with mining equipment manufacturer Caterpillar aimed at reducing the company’s carbon emissions from diesel-powered machines in mining operations.

According to Newmont, diesel combustion machines used in surface and underground mining contribute significantly to its carbon emissions.

Newmont chief operating officer Natascha Viljoen said: “As we look toward the future, our focus remains on creating a safer and more productive mining environment and this battery-electric large mining truck is one more step we are taking to further advance our safety and sustainability commitments.”

The collaboration between Newmont and Caterpillar will concentrate on the validation and testing of the Early Learner 793 XE. These activities are crucial for understanding how battery-electric large mining trucks can be integrated into mining operations and are expected to establish a new benchmark for the industry.

Caterpillar Resource Industries group president Denise Johnson said: “As the mining industry navigates the energy transition, we know a diverse set of solutions will be required for our customers to achieve their operational and sustainability objectives.

“We are excited about our collaboration with Newmont and working with them to truly understand the implementation and impact of the Early Learner 793 XE at CC&V.”

Caterpillar’s development of its first battery-electric 793 prototype was supported by key mining customers through the company’s Early Learner programme, which was launched in 2021. The prototype’s successful demonstration took place in November 2022.

The Cat 793 XE reached select customer sites for further testing and validation in September 2024. Seven of these trucks were constructed and tested at Caterpillar’s Tucson Proving Ground facility in Green Valley, Arizona.

This step signifies the second development phase of Caterpillar’s Early Learner programme and continues the momentum from the prototype’s demonstration.

Rio Tinto to trial battery swap trucks at Mongolia’s Oyu Tolgoi copper mine
The first truck will arrive at Oyu Tolgoi mine in Mongolia this year, with the remainder planned for mid-2025.

November 6, 2024

Rio Tinto will trial battery swap technology for electric haul trucks at the Oyu Tolgoi copper mine in Mongolia by partnering with China’s State Power Investment Corporation (SPIC).

The two-year project will involve eight haul trucks with a 91t payload, 13 batteries with 800kWh of capacity, and a robotic battery swap and charging station.

The first truck is scheduled to arrive at Oyu Tolgoi this year, with the full fleet and infrastructure expected to be commissioned by mid-2025.

This innovative technology, already applied on haul trucks in mining operations across China, allows vehicles to exchange depleted batteries for charged ones, bypassing the need for static charging stations.

This swift exchange is set to minimise downtime and offer more flexibility.

The trucks will be used for tasks such as tailings dam rehabilitation and topsoil movement, with Oyu Tolgoi staff responsible for their operation and maintenance.

The batteries are designed to last up to eight hours, depending on the task, and the swapping process is expected to take around seven minutes.

These will be used in non-production activities at the mine’s above-ground operations.

Rio Tinto chief decarbonisation officer Jonathon McCarthy said: “By partnering with the State Power Investment Corporation, we will be demonstrating the latest technology and innovation available in China and assessing its potential to help decarbonise our operations quickly and cost effectively.

“This demonstration will allow us to explore applications for battery swap technology that deliver more flexibility and less downtime than current static charging technologies. This work will complement the electrification pilots of ultra class mining haul trucks planned for the Pilbara.”

Technical experts from Rio Tinto and Oyu Tolgoi have collaborated with SPIC and truck manufacturer Tonly to customise the equipment to meet Rio Tinto’s electrical and safety standards.

Rio Tinto operates approximately 700 haul trucks globally, with 100 in the small-to-medium class range.

vouais ... mais production d'énergie en Mongolie

https://fr.wikipedia.org/wiki/Énergie_en_Mongolie

La consommation d'énergie primaire en Mongolie, d'environ 5 millions de tonnes équivalents pétrole en 2017, a été multipliée par deux depuis 2002. Le charbon pèse pour 70 % dans le mix énergétique, suivi par le pétrole (26 %) et la biomasse non-renouvelable (3 %)2. Cette consommation élevée au regard du nombre d’habitants, et fortement carbonée s'explique par un climat particulièrement rude, les températures pouvant descendre jusqu'à -30 °C à Oulan-Bator, considérée comme la « capitale la plus froide du monde »3

[energy_isere]

Oui, mais qui te dit que la compagnies minière ne va pas installer dans le coin disons 20 MW à 50 MW de parc solaire PV dans le futur ?

[GillesH38]

vouais ça va etre bien en hiver la nuit ....(45 % de latitude Nord comme la France) Il vont peut etre pouvoir bosser entre 11h et 13 h ? et encore quand il ne neige pas ?

et puis les matières premières, c'est comme l'agriculture, c'est très compétitif, donc si il y en a qui produisent du cuivre moins cher parce qu'ils s'emmerdent pas avec des camions électriques et qu'ils peuvent bosser nuit et jour et toute l'année ... tu vois le problème ?

Tu te gausse une fois de plus, mais si tu te trompais ? Il y a ceux qui pensent différemment comme Rio Tinto : viewtopic.php?p=2402525#p2402525 avec cette expérience ils pourront bien recharger des engins electriques avec.

je me moque pas mais tu penses qu'il y aura quel facteur de charge en hiver quand ce sera nuageux avec les panneaux PV de Rio Tinto ?

Et bien ils ont bien du penser à la probabilité que ça arrive.

Donc soit les mecs joueront aux cartes, ou soit les générateurs diesels de secours seront mis en marche.

certainement oui !
après je n'ai rien contre économiser du gazole en été, c'est toujours ça de pris.

Attention a ne pas tomber dans la naivete'. Est-ce un projet de long terme, ou un affichage qui permet de repondre a la pression sociale ? C'est ultra-courant que des politiques ou des compagnies communiquent sur un objectif contraire a leur objectif principal, pour equilibrer leur image. De nombreuses pubs pour les grosses voitures polluantes sont accompagnées d'un blabla débilos sur l'écologie, ou quand la droite baisse fortement la fiscalité des plus riches, elle communique sur les 15 euros de rentree scolaire qu'elle donne aux plus pauvres. Ce sont des stratégies standard ou la comm habille le réel pour qu'il soit socialement acceptable.

Pour les compagnies, il ne faut pas fantasmer. Soit elles ont des avantages a passer a l'electrique ( moins cher, moins de difficulté d'approvisionnement..), soit elles sont contraintes par reglementation. Mais elles ne vont pas comme ca juste pour etre bien gentilles dans un monde de bisounours baisser leur empreinte carbone. Le communiqué de Reuters nous prend pour des gros neuneux quand il dit que la compagnie va baisser son empreinte carbone, comme si c'etait un but en soi pour une grosse compagnie.
