Hitachi Energy and BluVein to combine technologies in electrification MoU

Hitachi Energy and BluVein, an innovator in dynamic charging technology, have signed a Memorandum of Understanding (MoU) to, they say, accelerate the electrification of heavy haul mining fleets and solve one of the biggest challenges in decarbonising mine operations.

Hitachi Energy’s advanced power electronics and digital charging technologies allow BluVein’s e-rail charging technology to deliver electricity safely and reliably to haul trucks of up to 400 t while transporting materials.

The collaboration will fast-track the development of a high-powered, fast and flexible dynamic charging solution for surface and underground mines and quarries in Australia and across the globe. BluVein will focus on its leading-edge e-rail and connection of the truck, which Hitachi Energy will further complement with advanced power electronics and digital solutions to power and monitor the whole system.

“This strategic collaboration with BluVein will enable our mining customers to trial next-generation dynamic charging solutions vital for achieving net-zero emission targets without compromising on operating practices or productivity,” Marco Berardi, Head of Grid & Power Quality Solutions and Service business at Hitachi Energy, said. “We believe this new collaborative approach will deliver on our common goal to accelerate the transition to all-electric mining and a carbon-neutral future.”

James Oliver, CEO at BluVein, added: “This MoU supports BluVein’s mission of partnering with a technology leader to deliver a universal dynamic connector that facilitates the removal of fossil fuel from mines and help propel the industry globally to meet its decarbonisation goals. Together, we are helping the industry move to a more sustainable and responsible future.”

Hitachi Energy and BluVein are also exploring the off-vehicle hardware requirements for BluVein1 for underground and smaller fleets, while actively cooperating on BluVein Proving Grounds, currently under construction in Queensland, Australia.

BluVeinXL: aiming for benchmark status in the haulage fleet electrification game

Since being named one of eight winning ideas selected to progress to the next stage of the Charge On™ Innovation Challenge in 2022, BluVeinXL has done more than most, assembling a consortium of major mining partners focused on accelerating BluVein’s standardised dynamic charging technology to decarbonise the mining sector.

Late last year, Austmine, which manages the BluVeinXL project, welcomed Rio Tinto, OZ Minerals, BHP, Newcrest Mining, Evolution Mining and Freeport-McMoRan to the consortium of funding members to fast-track the BluVein technology. It has since welcomed Vale to the consortium.

These companies have backed the vision of BluVein, a joint venture between Olitek (Australia) and Evias (Sweden), to dynamically power mixed-OEM haul fleets while in motion, enabling smaller on-board battery packs, faster vehicle haulage speeds up ramp, grid load balancing, elimination of static fast charging, maximum fleet availability and – most importantly – the complete elimination of diesel.

These consortium partners are focused on delivering BluVein’s fleet electrification solution to Technology Readiness Level (TRL) 6 with a minimal viable product (MVP) demonstration, ahead of full commercial deployment of the technology.

BluVeinXL leverages much of what was developed for BluVein1, the primarily underground solution using the BluVein Rail™ slotted power rail system and the on-vehicle BluVein Hammer™ to simultaneously charge and power mining fleets ‘on the go’. The Rail is an enclosed electrified e-rail system mounted above or beside mining vehicles while the Hammer connects the electric vehicle to the Rail.

In underground scenarios, BluVein’s technology completely removes the need for battery swapping or static fast charging while allowing the use of smaller, lighter and lower cost batteries in continuous and high-duty applications, according to the company.

In open-pit operations, BluVeinXL will be similarly transformative, offering a next-generation alternative to what BluVein refers to as “the cumbersome, inflexible and expensive conventional catenary wire trolley systems that are currently hampering mines from fully decarbonising their haulage operations”.

To get the latest on the BluVeinXL open-pit electrification solution, IM caught up with James Oliver, CEO of BluVein.

IM: Now you have the founding consortium members confirmed for BluVeinXL, where do you go from here? Are you currently engaged with major OEMs on creating a standard design that can fit on any truck?

JO: Seven consortium members is just the start, and we will be announcing additional members very soon. We greatly value our members as it is ensuring we get ‘voice of industry’ and the key technical requirements during this critical stage. One of the major benefits our members see in BluVein is our standardisation, meaning our technology can be used with mixed-OEM fleets, mixed machine types and can even be used to make alternative clean fuel use more efficient and cost effective.

We are currently working with two to three major fleet OEMs and progressing agreements related to integration and demonstration of the BluVeinXL technology. We are confident we will be able to demonstrate with at least one OEM as the MVP, and hopefully more during the current project. Once we agree with each OEM the agreed interface point, then the BluVeinXL integration with the various fleet types becomes quite simple. To do this our technical team works closely with the OEMs on all aspects of the integration including Hammer, Rail and the control systems. By standardising with our various OEM fleet partners, we are delivering on what the mining customers are demanding – a truly standardised dynamic charging system.

James Oliver, CEO of BluVein

IM: How are you managing to engage OEMs that are also providing their own trolley assist applications that, they believe, may be suitable for similar haul truck propulsion setups to BluVeinXL?

JO: BluVein’s safe and proven electrification technology is based on over a decade of research and development undertaken for electric highways by our joint venture partner Evias. We are confident in our system’s ability to deliver high power transfer whilst also delivering on the safety and robustness requirements demanded by mining customers. Critically, the high-power transfer characteristics of BluVein’s slotted rail system enables simultaneous on-ramp hauling and charging of multiple closely spaced mining haul vehicles. This is a game-changing capability and of high interest to our mining partners. The conventional catenary wire-based trolley systems have limitations on power delivery capacity, earthing and other critical safety elements, and, therefore, are not as favoured by miners.

We do, however, see benefits of OEMs trialling a range of different mine electrification approaches, as long as we can all agree on a common vehicle connection point, specifically at the dynamic charge interface. This will ensure the end customer is able to select the best solution for their individual sites. We understand that BluVein will not be everything to everyone, but for the applications it does suit, we are confident it will be a true game changer over conventional catenary and static fast charging options for haul truck fleets.

We hope to be able to demonstrate BluVeinXL side by side with a catenary wire system to showcase the competitive advantages BluVeinXL has – that is higher power transfer; safer, easier to install, use and relocate; and overall lower cost. Ultimately it will be up to the customer to choose based on the performance of the system and we think this will stack up in BluVeinXL’s favour.

IM: Can you expand on how your system alleviates the requirements on haul road conditions that typically comes with the current generation of trolley assist technology? Do you see your Rail and Hammer technology being able to work in any conditions (the Arctic included)?

JO: Part of our current package of work is to understand with our mining partners what these extremes are to ensure we are developing a solution that has minimal up-stream and down-stream impact on operations. The vision is to have a deployable solution that suits all climates and terrains.

Our core technology partner, Evias, has spent over a decade developing BluVein’s core technology to function effectively in icy and muddy conditions. By building on these learnings, we are confident that BluVeinXL will work in the vast majority of terrains and climates experienced in mining – from the hot and humid Pilbara region of Australia to the coldest parts of northern Canada.

It is BluVein’s safe slotted e-rail technology that enables it to be located near to the ground to the side of haul roads. Our Hammer and Arm is being designed to cater for the full range of haul road conditions, thereby reducing the burden on mines to maintain haul road conditions to perfection as is required with conventional overhead wire catenary systems.

Our consortium members have very good geographic spread to help us understand and test in these conditions. Part of our current work is to clearly understand from our mining partners what these environmental extremes are to ensure our solution will function effectively in all operations.

IM: Has your work to this point indicated how small the on-board batteries could be in a typical open-pit scenario for 220-t-payload trucks?

JO: We have taken a technology-agnostic approach to what on-board power and storage system we are supplying; our current focus is getting enough energy onto the vehicle as efficiently and safely as possible to power drive motors and charge smaller batteries if and when available. While we cannot reveal exactly how much smaller we can make the batteries, early studies show the batteries can be reduced as much as 60% when coupled with dynamic charge that has enough capacity to power the drive and charge the battery.

BluVein1 for underground and quarries can provide up to 3 MW of power sufficient for up to 100-t payload vehicles

IM: So what payloads do you think you could be providing this solution for?

JO: The BluVein Rail and Hammer design is completely scalable. BluVein1 for underground and quarries can provide up to 3 MW of power sufficient for up to 100-t payload vehicles. The BluVeinXL system can offer in the range of 4-7 MW, sufficient for up to 250-t payload vehicles. Our engineering team plan to use BluVein1 and BluVeinXL as stepping stones for an eventual introduction of a BluVein solution suited to ultraclass fleets with 9-12 MW of capacity sufficient for up to 350-400 t payloads.

IM: Where are you with your field trials on this solution? Do you expect these to commence this year?

JO: The targeted ‘wheels on track’ for BluVein1 is 2023, followed closely in 2024 with the BluVeinXL MVP demonstration. Right now I cannot reveal too much but there are some exciting partnerships being progressed to achieve this.

In terms of field trials, our ideal setup – and I think one the industry really wants – is a single site where all key mine electrification technologies can be tested out side-by-side. There are some very positive conversations going on between all three parties – the solution OEMs, truck OEMs and mining companies – on this front, which is exciting for BluVeinXL.

As has been said many times, there is no ‘silver bullet’ when it comes to mine decarbonisation. We know that BluVein’s dynamic charging solutions will tick a lot of boxes, but not all. So, it’s great if we can work together to ensure we cover any gaps. There is just too much at stake to try and go it alone.

IM: Anything else to add on the subject of electrification and dynamic charging?

JO: One question we have been asked is does BluVein’s Hammer and Rail technology only support dynamic charging? While power transfer while in motion is our obvious advantage, our system is basically an automated IP2X-rated power connection that can transfer more than 4 MW of energy. Could we use this for automated static fast charging also? Our answer to that is absolutely.

BluVein’s underground dynamic charging developments accelerating

BluVein, after officially receiving agreement and project approval from all project partners, has initiated the third phase of technology development and testing of its underground mine electrification solution, BluVein1, it says.

BluVein is a joint venture between Australia-based mining innovator Olitek and Sweden-based electric highways developer Evias. The company has devised a patented slotted (electric) rail system, which uses an enclosed electrified e-rail system mounted above or beside the mining vehicle together with the BluVein hammer that connects the electric vehicle to the rail.

The system, which is OEM agnostic, provides power for driving the vehicle, typically a mine truck, and charging the truck’s batteries while the truck is hauling load up the ramp and out of an underground mine.

The underground-focused development under BluVein is coined BluVein1, with the open-pit development looking to offer dynamic charging for ultra-class haul trucks called BluVein XL. This latter project was recently named among eight winning ideas selected to progress to the next stage of the Charge On Innovation Challenge.

The purpose of the third phase of the BluVein1 technology development is to:

  • Conduct a full-scale refined hammer (collector) and arm design and testing with a second prototype;
  • Execute early integration works with mining partners and OEMs;
  • Provide full-power dynamic energy transfer for a vehicle demonstration on a local test site; and
  • Confirm a local test site for development.

IM understands that the company is close to sealing an agreement for a local test site where it will carry out trials of the dynamic charging technology.

James Oliver, CEO, BluVein, said the third phase represents an essential final pre-pilot stage of BluVein1.

“It excites me that the BluVein solution is becoming an industry reality,” he said. “The faster BluVein1 is ready for deployment, the better for our partners and the mining industry globally.”

BluVein recently entered a Memorandum of Understanding with Epiroc, where the Sweden-based OEM will provide the first ever diesel-to-battery-converted Minetruck MT42 underground truck for pilot testing on the slotted electric rail system from BluVein.

“This MoU also ensures that we are designing and developing the system into a real-world BEV for full-scale live testing and demonstration on a pilot site in 2023,” BluVein says.

In addition to Epiroc, IM understands BluVein is working with Sandvik, MacLean, Volvo and Scania, among others, on preparing demonstration vehicles for the BluVein1 pilot site.

The BluVein1 consortium welcomed South32 into the project in May, joining Northern Star Resources, Newcrest Mining, Vale, Glencore, Agnico Eagle, AngloGold Ashanti and BHP, all of which have signed a consortium project agreement that aims to enable final system development and the construction of a technology demonstration pilot site in Australia.

The project is being conducted through the consortium model by Rethink Mining, powered by the Canada Mining Innovation Council (CMIC), which CMIC says is a unique collaboration structure that fast-tracks mining innovation technologies such as BluVein and CAHM (Conjugate Anvil Hammer Mill).

Carl Weatherell, Executive Director and CEO, CMIC/President Rethink Mining Ventures, said: “With the urgent need to decarbonise, CMIC’s approach to co-develop and co-deploy new platform technologies is the way to accelerate to net zero greenhouse gases. The BluVein consortium is a perfect example of how to accelerate co-development of new technology platforms.”

Oliver concluded: “The BluVein1 consortium is a great reminder that many hands make light work, and through this open collaboration with OEMs and mining companies, we’re moving faster together towards a cleaner, greener future for mining.”

Newcrest’s Lihir operation boosts safety with latest Olitek Anako Sense solution

Newcrest Mining’s Lihir operation in Papua New Guinea has commissioned an improved Temperature Measuring Unit (TMU) that, it says, further enhances safety for personnel working at its geothermally active open-pit operations.

This second generation TMU, called Anako Sense, follows the commissioning of the Anako 13 prototype on March 6, 2018, at Lihir. The unit engineers out the risk of personnel exposure to geysering events during drill hole measurement activities, according to the technology developer Olitek Mining Robotics (OMR).

Anako 13 allowed geothermal technicians to operate a mobile arm from the vehicle remotely, while simultaneously lowering or raising a probe safely to measure and record temperature, water level and depth within blastholes. It was designed to mechanise this quality monitoring process in the open pit, removing operators from danger and putting them in the safety of an air-conditioned cabin.

The Mark 2 machine just delivered to Lihir provides faster than manual cycle times, while eliminating fatigue, repetitive strain injury and exposure risks, according to OMR. It also provides real-time data capture of borehole quality measurements.

Newcrest teams collaborated with several business partners to deliver the Anako Sense unit early this year, allowing geothermal technicians to continue carrying out their work safely as Lihir’s mining pit phases extend deeper and further north into Kapit orebody, the miner said.

Lihir Manager – Mine Technical Services, Ben Likia, thanked various Newcrest teams and business partners for delivering the project safely and ensuring a timely site deployment of Anako Sense, including training sessions for key personnel.

“I also congratulate our national employees who completed their training sessions,” he said. “We have competent geothermal personnel who are now operating the new TMU, and several mobile maintenance personnel who will assist in ensuring the TMU is regularly maintained and fit for purpose.

“The safety of our people in Lihir is our number one priority, and this improvement is testimony to that. We are committed to ensuring everybody goes home safe and healthy every day.”

While Anako Sense has obvious applications at mine sites with geothermal hazards like Lihir, the technology’s appeal is much broader, according to James Oliver, OMR’s Managing Director.

“Anako Sense could be used and applied at any mine operating in freezing cold conditions, at high altitudes, located in inland deserts, or around voids,” he said. “The quicker we get people off the bench and into safe vehicle cabins, the better off the industry will be. The development of Anako Sense will help that transition.”

Lihir Superintendent – Geothermal Operations, Kaipale Pano, said the enthusiasm and feedback from the project team and personnel had been heartening.

“The project is a success for Newcrest Lihir because we (Newcrest) encourage employees to experiment with new ideas to improve safety and production performance,” he said. “We displayed Newcrest’s practice – ‘Bottom-up Innovation’ – and values – ‘Working Together’ and ‘Innovation and Problem Solving’ – through this project.

“We are proud to have the best people and outstanding operators, mostly Papua New Guineans, who constantly team up to deploy safe and latest mining technologies at Lihir.”

The name Anako was inspired by an incident at Lihir nine years ago. In 2013, Samuel Ayata, a Geothermal Technician from Eastern Highlands and Morobe, sustained injuries from geysers when collecting blasthole data. His father, Ayata Anako, collapsed upon receiving news about the incident and was bedridden for almost three weeks, pleading with his son to quit his job.

Ayata said: “The scars on my body were a drive for our team to take on this safety initiative and continue improving it; we named the TMU after my father. I thank Newcrest for supporting our commitment to work safely for our families.”

Olitek on a mechanisation mission to provide mine safety step change

IM’s Teams call with Olitek Mining Robotics’ (OMR) James Oliver and Newcrest’s Tony Sprague starts like many other meetings, with a safety share.

Centred on the experiences of a drill and blast expert, Barry Crowdey, owner of Blastcon Australia Pty Ltd, this ‘share’ goes some way to highlighting mining’s hidden safety problem.

“So often we hear about safety shares that are almost instantaneous: rock failures, rock bursts, collapses, vehicle incidents, energy releases, ground collapses, or somebody getting pinned against something,” Oliver, OMR’s Managing Director, told IM. “You have this instantaneous safety hazard you are always trying to protect against.

“The ones that don’t get reported – and are possibly creating a big stigma in the mining industry – is the ongoing wear and tear on the human body.”

Crowdey, a blasting consultant, offers direct experience here.

As a charge-up operator, he was recently side-lined for six months after major shoulder surgery. A whole host of repetitive tasks – such as push and pull activities during blasthole preparation and charge-up – conducted over the last two decades had proven too much for his body.

“A charge-up operator is a highly sought-after job,” Oliver said. “The perception is: you have to be tough to do it well. Barry never complained about this – which probably speaks to awareness around men’s mental health to a degree – and would often use his time off to recover from body soreness likely caused by these repetitive tasks.”

The injuries that don’t get reported – and are possibly creating a big stigma in the mining industry – are the ongoing wear and tear on the human body, James Oliver says

He added: “After stories like this, it is no wonder the mining industry has a stigma for wearing people out and, essentially, taking away more than it is providing – personally and from an environmental perspective.”

Sprague, Group Manager, Directional Studies and Innovation at Newcrest, has experienced some of the strains placed on the human body by carrying out similar manual tasks on mine sites, reflecting on a three-month stint on a blast crew in Kalgoorlie at the height of summer.

He, Newcrest and the wider mining industry are responding to these issues.

For the past three-or-so-years, Newcrest has been collaborating closely with OMR to develop a range of smart, safe and robust robotic systems enabling open-pit mechanised charge-up, blasthole measurement and geological blasthole sampling, as well as underground remote charge-up for tunnel development.

This suite of solutions is tackling a major industry problem that most mining OEMs focused on automating load and haul, or drilling operations, are not looking at.

OMR is addressing this market gap.

“Apart from a small number of mines and in specific applications, the mining industry is generally not ready for automation,” Oliver said. “Effective mechanisation of the hazardous mining tasks is what is needed first. This is where design thinking is crucial – process review, deletion, modification and optimisation to enable robotic mechanisation.”

Sprague added: “Most processes in mining have been designed for fingers and have taken hundreds of years to be optimised around them. We now need to mechanise these processes before we can start thinking about automating.”

The metric for momentum

The injuries that OMR and many others are looking to alleviate with mechanisation of these manual processes are not generally captured by lost time injuries or other similar safety metrics.

Most processes in mining have been designed for fingers and have taken hundreds of years to be optimised around them, Tony Sprague says

This has historically made it hard to invest in such technology – the numbers don’t typically show up in the WH&S reporting.

Yet, the risk of not confronting this issue is starting to have more sway over operational decision making at the same time as technology is reaching a suitably mature level.

“The image of Barry at home recovering from surgery to address career-induced injuries is not the image the mining industry wants to portray any longer,” Oliver said.

And with mining companies competing with other industries for skilled talent, they can no longer afford to put such stress on their people.

The idea, as OMR says, is to maintain process performance with well executed mechanised equipment. “Strain the machinery, not the people” is one of the company’s mottos.

And it will only take a few more frontrunners adopting such technology to affect real change across the industry, according to Oliver.

“Socially, people will speak,” he said. “If the mine down the road has someone in the comfort of an air-conditioned cabin carrying out remote charge-up operations, that news will soon spread. Operators will no longer tolerate being exposed to rock bursts, injuries and the like, and will leave positions where they are put in such a situation.”

It is such momentum that has, arguably, led to the industry backing innovators like OMR.

One of the company’s products, the Remote Charge-up Unit (RCU), is now the subject of a major collaborative project managed by the Canada Mining Innovation Council (CMIC).

Seeking to alleviate the issues associated with loading and priming explosives at the development face, the RCU’s core enabling technology is OMR’s innovative “Trigger Assembly” (pictured below), which enables lower cost conventional detonators to be mechanically installed safely and efficiently. This system is fitted to a modified Volvo wheeled excavator, with its hydraulic robotic boom, and is the key to moving people away from harm’s way in the underground mining setting.

The project is being delivered in a series of development phases through to Technology Readiness Level 7. This functioning prototype machine will enable personnel to move at least 4-5 m away from the underground development face and carry out efficient and effective face charge-up.

This project is moving into the procurement and build phase of the first prototype, according to Oliver.

Newcrest is also one of the major miners steering developments of the RCU, alongside Agnico Eagle, Glencore and Vale within the CMIC collaboration.

While Sprague says his company has injected early seed funding to get some of the OMR work moving, he thinks industry collaboration is key to bringing the products to market.

“What got me into wanting to do these sorts of projects is the belief that the mining industry can be so much better than it currently is,” Sprague said. “We can change this faster by finding smart, agile companies like Olitek and support them with groups of like-minded mining companies to accelerate projects. We are showing that when the industry works together, we can make solutions to our problems appear.

He added: “I’m a true believer that momentum breeds momentum. In these types of projects, I use my finite seed funds and stretch them as far as possible. I might not know how to get to the end of a project in terms of funding it, but if I can get it to a point where we have some TRL3 designs and lab testing to prove the concept, you can go out to the market and find ways to progress up through the technology readiness levels.

“It is about chipping away and progressing up through the TRLs as opposed to asking the industry to blindly invest in R&D.”

Moving up a level

And this is where most of OMR’s technology suite is at: TR5 to TRL6 level.

Oliver explained: “If we look at the RCU unit at the moment, we have a robotic excavator platform that was developed on a sister project. This modular approach we are taking has allowed us to go into new applications seamlessly because of the base technology building blocks we have created.”

Alongside the RCU, the company is working on an “Anako” suite of products, namely: Anako Sense, Anako Sample and Anako Prime.

Anako Sense is a borehole probe sensing machine allowing operators to remotely measure the depth, temperature and presence of water within blastholes. It has been designed to mechanise this quality monitoring process in the open pit, removing operators from danger and putting them in the safety of an air-conditioned cabin. The Mark 2 machine – which is now commercially available – provides faster than manual cycle times, while eliminating fatigue, repetitive strain injury and exposure risks, according to OMR. It also provides real-time data capture of borehole quality measurements.

Anako Sample provides a mechanised sampling process to collect blasthole data. It, again, removes personnel from harm’s way, while providing fast cycle times and repeatable sample quality. It also provides automated data recording. This technology is currently going through Factory Acceptance Testing, with plans to deploy to a customer site shortly.

Anako Prime – for mechanised open-pit charge-up – provides all the benefits of the other Anako products while being compatible with multiple types of explosives. It is leveraging the developments made in the underground environment with the RCU and has a Mark 1 machine completed. Progress is also being made on a Mark 2 version to achieve high productivity, fully mechanised priming and bulk emulsion placement, according to Oliver.

While more products could be added to the OMR portfolio in time, the company is focused on leveraging the proven Volvo wheeled and excavator platform that can scale up from 6 t to 60 t capacities and can move quickly around the mine.

Given the strong collaborative relationship OMR has fostered with Volvo over the years, there is also potential down the line for the Volvo network to support these machines across the globe, providing the machine uptime safety net that many remote mine operators would like if they were to take up the OMR technology option.

The inspiration

Crowdey’s role in this story does not end with the safety share. He is also now training operators on this new equipment, providing a real-life example of the reason to adopt such mechanisation as well as how easy that adoption process is.

Sprague said: “You might think you need to be an expert excavator operator to work these technologies, yet the smart controls, vision and positioning systems for hole location, for instance, means the machines do the hard work for you.”

Oliver added to this: “We say a trainable operator can be sat in that machine and, after a matter of days, be as efficient as a manual operator.”

There is an impending deadline for mine operators to confront these issues, with mechanisation of the most dangerous processes the first port of call, according to Oliver.

“The only way to stop this mining impact is about enabling machinery to do the work and going through a mechanisation process to ensure the Barrys of this world don’t have to conduct these manual processes,” he said. “A good example of that over the last decade is the installation of hose feeders on emulsion pumping units in blasthole charging. That represents a ‘step’ in the right direction, but what we need now is ‘step change’.

“Eventually there will be places in a mine that people simply cannot go, so we better start perfecting mechanisation now as automation will be needed one day. It might be 10 years from now, but, if we’re not mechanised by that point, we will simply not be able to mine these more challenging ore deposits.”
