Finland-based engineering firm, Etteplan says it is collaborating with Epiroc to enable fossil free underground heavy transportation without interruptions and, more specifically, helping redesign its Minetruck MT42 Battery into an electric trolley system.

As part of a strategic partnership project that started in 2021, Etteplan’s offices in Finland and Sweden are providing what it says are crucial resources and expertise in the development, helping secure a timely progress of the project. It is providing technical expertise for battery technology, machine electrification, electrical design, system requirements and safety risk assessment.

Last year, Epiroc, for its part, announced a collaboration with ABB and Boliden to develop an all electric battery trolley truck system based on the MT42 Battery truck for underground mining, with the trio planning to demonstrate the system on a test track in the underground polymetallic Kristineberg mine in Sweden.

For Epiroc, the trolley truck project is one of the initiatives to meet its ambitious sustainability targets and forms part of its electrification journey, Etteplan said. The new battery-electric Minetruck MT42 trolley will still be equipped with a battery and, in addition, it will be recharged on the fly via an overhead catenary wire through a pantograph, similar to a trolley bus.

Anders Svensson, Director, Service Solutions at Etteplan’s Engineering Solutions, said: “Globally, electrification of equipment is a major trend in mining, where most vehicles are currently powered by diesel engines. Therefore, the industry needs new types of competences and skill sets that we are ready to cater for. Jointly developed procedures together with major manufacturers such as Epiroc ensure that we address strategically important electrification challenges in a competitive way.”

Etteplan has worked with Epiroc, previously part of Atlas Copco, for over 20 years, and the project aligns with Etteplan’s electrification vision while showcasing how it works closely with customers to enhance their battery performance and functionality in different industries.

Remote Energy takes fuel efficiency to next level with iON-DRIVE

Remote Energy has launched iON-DRIVE – the most compact, fuel-efficient solution in its anti-idle range.

The iON-DRIVE is a roof-mounted DC HVAC system with a built-in lithium-ion battery bank. The battery-powered HVAC system allows the truck’s main engine to shut off at idle while keeping the cab cool, reducing unnecessary idle time. With its purpose built, mine-spec steel assembly coupled with the highly efficient large face evaporator, the iON-DRIVE sets the standard for rooftop air conditioning systems in tough work environments, according to the company.

The iON-DRIVE has the capacity to run the HVAC system continuously for up to 30 minutes, with the built-in lithium-ion battery charged by the haul truck’s main battery bank, via a DC-to-DC charging interface.

Installation of the system on the cabin roof is simple, with the need to connect only two cables to the truck’s battery bank.

“The iON-DRIVE is most suited to haulage cycles with short idle times, allowing for sufficient battery charging from the truck’s main engine,” the company added.

Among the key benefits of iON-DRIVE are reduced fuel consumption and carbon emissions; lower maintenance costs; the extension of service intervals and asset life; the ability to maintain operator comfort; increase available operating shifts; and the ability to improve operating redundancy with the installation of a second HVAC system.

Remote Energy Director, Chris Baumann, said: “We see that the iON-DRIVE provides a simple and unique anti-idle solution for haul truck fleets with lower idle times. With the continued push to find ways to operate more efficiently and reduce emissions, the iON-DRIVE is one solution that is available today, to reduce unnecessary fuel burn at idle.

“With the addition of the iON-DRIVE to our range of anti-idle solutions, we now have a solution for each unique application and can provide idle reduction for various haul cycle scenarios.”

BHP and TransAlta agree on solar, battery power system for Mt Keith and Leinster

BHP and its power partner in the Goldfields of Western Australia, TransAlta, are to build two solar farms and a battery storage system to help power the Mt Keith and Leinster nickel operations.

This will help BHP reduce emissions from electricity use at Mt Keith and Leinster by 12%, based on financial year 2020 levels.

The Northern Goldfields Solar Project will include a 27.4 MW solar farm at Mt Keith and a 10.7 MW solar farm and 10.1 MW battery at Leinster, and will displace power currently supplied by diesel and gas turbine generation, BHP said.

This will result in an estimated reduction of 540,000 t of CO2e over the first 10 years of operation. This is the equivalent of removing up to 23,000 combustion engine cars from the road every year, according to BHP.

BHP commissioned the solar farms and battery to be built, owned, and operated by TransAlta as part of the Power Purchase Agreement (PPA) extension signed in October 2020. Construction will commence in the December quarter, is expected to take 12-14 months and, at its peak, will employ over 100 people on site.

BHP Nickel West, Asset President, Eddy Haegel, said: “This is the first large-scale onsite solar farm and battery that BHP has commissioned at any of its global operations.

“The Northern Goldfields Solar Project will further improve our position as one of the lowest carbon nickel miners in the world. It will reduce emissions from electricity use at Mt Keith and Leinster by 12%, reduce fuel costs and improve the reliability of our electricity supply with the addition of the battery storage system.

“This announcement follows the nickel supply agreement we signed with Tesla last week. Sustainable low carbon nickel is essential for our battery and electric vehicle customers.”

TransAlta Corporation President and Chief Executive Officer, John Kousinioris, said: “We are proud to be supporting BHP’s emissions reduction targets and sustainability goals through the expansion of our renewable generation footprint into Australia.”

The partnership will contribute to BHP’s medium-term target to reduce Scope 1 and 2 emissions from our operated assets by at least 30% from financial year 2020 levels by its 2030 financial year.

The project is subject to final Western Australia state government approvals.

OZ Minerals to trial hybrid energy solution at Carapateena as part of renewables project

OZ Minerals says it has launched the Energy and Mining Collaboration (EMC) in an initial collaboration with six other organisations to investigate renewable energy and demand management related activities on a mine site.

The six other organisations are Adelaide University, CSIRO, the Department of Energy and Mining, the Rocky Mountain Institute, SunSHIFT and the Tonsley Innovation Precinct.

The first project as part of this program will be a trial installation of a circa-250 kW hybrid energy solution facility including solar, wind and a battery in the first half of 2020, located at OZ Minerals’ Carrapateena mine site in an area demarcated for piloting and prototyping. Carrapateena, in South Australia, is on track for first concentrate production in the December quarter, after which the project will ramp up to full production over the following 18 months. Carapateena is expected to produce an average of 65,000 t/y of copper and 67,000 oz/y of gold over a 20-year mine life.

The trial installation will have approximately 250 kW hybrid energy solution consisting of solar, wind, battery storage, connected to existing diesel generators, and have a Smart Grid controller for data access and tracking.

The EMC brings these organisations together into a collaboration platform with a view to developing and identifying renewable energy opportunities for an international showcase that optimises electrical and fuel demand and the integration of renewable energy systems, OZ said.

“This will be done via the creation of true partnerships around the testing of energy and technology hypotheses to unlock transformational value in mining,” the company added.

“Over the next six months, the parties, as the founding collaborators, are committed to formalising the partnerships from this collaboration, inviting in other first partnership collaborators and creating a broad and global membership of all those who would like to participate.”
