WAE placing Fortescue in mine electrification pole place

Andrew Forrest’s assertion on Fortescue Metals Group’s deliberate acquisition of Williams Superior Engineering (WAE), an offshoot of the Williams F1 workforce based by the revered, late Sir Frank Williams CBE, again in January was hardly understated.

He mentioned: “This announcement is the important thing to unlocking the components for eradicating fossil gasoline powered equipment and changing it with zero carbon emission expertise, powered by FFI (Fortescue Future Industries) inexperienced electrical energy, inexperienced hydrogen and inexperienced ammonia.”

As time has progressed, the £164 million ($193 million) deal for the UK-based WAE closed (in March), and one other vital announcement within the type of a tie-up between FMG, FFI, WAE and Liebherr has adopted, the FMG Founder and Chairman’s phrases have seemed more and more prescient.

This grew to become obvious to IM on a current go to to WAE’s Grove headquarters in Oxfordshire, England.

What FMG now has on its books and what FFI is managing within the type of WAE is arguably one of many world’s main decarbonisation expertise corporations.

WAE’s attain goes far past the pit lanes of a race monitor. Its impression is felt within the automotive, defence, aerospace, power, life sciences and well being care sectors – for instance, a Babypod 20, a Formulation One-inspired atmosphere for new-born infants in want of emergency transportation, was on show within the boardroom IM sat in throughout an interview at Grove.

One in all its newer market entries has been in mining, with WAE’s fingerprints on two of the {industry}’s main gasoline cell electrical car (FCEV) haul truck actions.

Previous to the acquisition by Fortescue, WAE offered “electrical structure and management {hardware} and software program” for the battery system on a 100-day “dash” FFI mission centered on changing a legacy 221-t class Terex Unit Rig MT4400 AC electrical drive, diesel-powered haul truck to run on a ‘inexperienced’ hydrogen 180 kW gasoline 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 12 months, WAE equipped a 1.2 MWh battery pack that, together with a number of gasoline cells amounting to 800 kW of energy, propelled the transformed 291-t-class Komatsu 930E across the mine website.

Enter to those two tasks put WAE on the mining map, however this represents a fraction of the impression the corporate is prone to have on mining’s decarbonisation journey going ahead.

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

Each tasks spotlight the depth of battery system expertise experience that led FMG to buying the corporate within the first place – design experience spawned from improvement throughout a number of sectors and working environments, utilising the newest cell expertise throughout all type elements.

There’s a frequent thread that hangs between all this work, as Craig Wilson, WAE CEO, defined to IM.

“We develop our battery methods for the particular software, factoring within the responsibility cycle, the fee constraints, required efficiency and atmosphere the answer might be working in,” he mentioned. “In motorsport, for example, you may think about weight, aerodynamics and house are extra important than they’re in mining.”

Being battery cell, chemistry and format agnostic, WAE has constructed up a popularity within the battery {industry} for specifying and creating a various pool of battery methods that proceed to push efficiency to the restrict.

Differentiated modelling

Subtle modelling and simulation instruments – a lot of which has been developed in-house – are behind this, in accordance with WAE’s Chief Programme Supervisor, Alec Patterson.

“We’ve got detailed in-house simulation instruments which permit us to develop and optimise a battery pack’s efficiency in opposition to any buyer’s drive cycle standards,” he mentioned. “This contains thermal simulation the place the workforce mannequin the detailed internals of a cell, permitting them to know precisely how every cell is prone to behave and, thereby, with the ability to optimise their cooling for elevated efficiency. This comes from our motorsport heritage and the workforce’s means to govern and analyse massive quantities of knowledge via supercomputer ranges of processing energy.”

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

Battery design additionally requires a robust deal with security and that is the place WAE’s intensive sensible expertise is absolutely utilised.

“We’ve got detailed in-house simulation instruments which permit us to develop and optimise a battery pack’s efficiency in opposition to any buyer’s drive cycle standards,” Alec Patterson says

Patterson summarised this providing: “There are a selection of how the battery is developed to make sure cell security. These vary from understanding intimately the efficiency of the cell via sensible testing, the design of the modules themselves and the monitoring of the cells for voltage and temperature all through utilization. WAE has developed its personal Cell Monitoring Unit {hardware} and Battery Administration Unit {hardware} and, mixed, they monitor the standing of the pack and management the efficiency outputs many occasions a second. Within the FFI battery sub pack, dielectric (non-conductive) coolant is used so if a leak was to happen it wouldn’t trigger an inner difficulty; detection of which might be via WAE’s propriety on-board sensors.”

Overlay these preventative measures with an array of expertise in varied fields that might have seen battery methods take vital G-shock hundreds and function in excessive temperature environments – whether or not that be a crash on a Formulation E circuit or an Excessive E race within the Sahara – and it’s simple to see why FMG initially believed WAE had data and abilities transferrable to mining.

Patterson concludes that advances in high quality inside the manufacturing course of can even add to the reliability of the sub packs. At WAE these advances come within the type of laser welding, which ensures every cell is related robustly for optimum efficiency.

Battery prototype progress

All this and extra are being factored into the 221-t all-battery answer WAE is presently centered on as a part of the FFI and FMG transient.

The battery will take the place of the diesel engine and alternator and can plug immediately into the Terex MT4400 inverter to drive the motors and rear wheels. The battery system can have a capability of >1 MWh (ultimate specification to be revealed at a later date) and might be charged by a “fast-charge answer” sourcing energy from a renewable grid FMG has already setup as a part of its 60 MW Chichester Photo voltaic Fuel Hybrid Challenge.

As soon as the battery system is delivered, built-in into the truck and commissioned at FFI’s Hazelmere facility, will probably be transported to the Pilbara the place it would begin intensive testing exterior FMG’s present mining operations.

WAE, FMG and FFI have overcome quite a lot of hurdles to get to the purpose the place they’ll speak about such a plan.

Whereas a lot of the battery homes within the UK can take a look at every sub pack individually, WAE needed to find a specialist take a look at home able to testing out the complete battery pack from each a motor-drive perspective and a battery re-generation standpoint.

This has seen the entire answer – a 12 t motor, inverter, cooling system, battery system and energy distribution unit – start testing a couple of months again.

Charging packs of this scale is without doubt one of the main {industry} challenges presently.

“Our charging technique is centred across the particular person cell chemistry and type issue which permits us to specify the next charge of cost for the battery sub pack,” Patterson mentioned. “To allow quick charging, a mixture of a big charger and skill to chill the pack via the charging course of is required, and our pack is designed for each.”

On the identical time, WAE is aiming to additional optimise the regeneration facet of the electrification mission, realising that is key to getting the vans to finish as many haul cycles as attainable with out the downtime related to a battery recharge – even when it’s a ‘quick cost’.

“The actual problem is centred round find out how to handle the big accumulation of power from the wheel motor throughout braking or retarding downhill absolutely laden,” Patterson mentioned. “Do you ship this to the battery or the resistor grid to burn off? Our job is to optimise the ability electronics to ensure as a lot of that power as attainable goes again into the battery with the intention to make the entire system extra environment friendly.”

All the battery system will quickly be shipped to Australia to enter the Terex truck at Hazelmere, at which level the charging system will be absolutely examined and the re-generation system trialled.

Leveraging gravity

This work will little question affect the opposite large mission WAE is presently concerned in for FFI and FMG – the electrification of FMG’s rail operations.

Fortescue’s present rail operations embrace 54 working locomotives that haul 16 prepare units, along with different on-track cellular gear. Every prepare set is about 2.8 km in size and has the capability to haul 34,404 t of iron ore in 244 ore vehicles.

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

The regenerating battery-electric iron ore prepare mission will use gravitational power to completely recharge its battery-electric methods with none extra charging necessities for the return journey to reload, in accordance with FMG.

The challenges related to this mission embrace the scale of the battery and motor mixture required to retailer sufficient power from the absolutely laden, downhill journey from Cloudbreak to Herb Elliott Port to ensure the unladen trains can journey again with out a cost, and the residual energy and torque technology that might usually be utilized to get the locos began.

On the latter, Patterson mentioned: “Your contact space by way of the wheel to rail could be very small compared to the load, so our management technique will utilise studying from our in-house VDC (car dynamic management) software program to design an answer that controls slippage for optimum adhesion.”

If an applicable answer involves the fore, the sustainable worth is important for FMG.

Fortescue’s rail operations consumed 82 million litres of diesel within the 2021 monetary 12 months, accounting for 11% of Fortescue’s Scope 1 emissions. This diesel consumption and related emissions might be eradicated as soon as the INFINITY TRAIN is absolutely carried out throughout Fortescue’s operations, considerably contributing to Fortescue’s goal to realize “actual zero” terrestrial emissions (Scope 1 and a couple of) throughout its iron ore operations by 2030.

Electrification for everybody

Simply as WAE’s involvement within the conception of the primary Formulation E battery led to wider electrification in motorsport, WAE believes its work in mining can have far-reaching ramifications throughout the off-highway sector.

Simply how far reaching will probably be is dictated by probably the most vital mission – by way of scale and timeline – WAE has on its books.

In June, FMG introduced a partnership with Liebherr for the event and provide of inexperienced mining haul vans for integration with the “zero emissions energy system” applied sciences being developed by FFI and WAE.

Underneath the partnership, Fortescue will buy a fleet of haul vans from Liebherr; a dedication that represents roughly 45% of the present haul truck fleet at Fortescue’s operations, with truck haulage diesel consumption representing roughly 200 million litres within the 2021 monetary 12 months, accounting for 26% of Fortescue’s Scope 1 emissions.

The zero emissions energy system applied sciences are anticipated to be fitted on machines based mostly off the 240-t T 264 mannequin to be deployed at its Pilbara mining operations. They might embrace each battery-electric and FCEV configurations, therefore the rationale why the all-battery prototype mission and the FCEV mission are so vital.

With the primary of the zero emission haul truck models anticipated to be absolutely operational inside Fortescue mine websites by 2025, FMG, WAE and Liebherr look set to take the electrification lead over its mining firm friends.

But Wilson says this kind of answer may flip right into a business product that others choose for their very own decarbonisation program – therefore the industry-wide electrification potential.

When requested the query whether or not the corporate should provide battery methods to the likes of Anglo American (because it did for the NuGen truck) below the brand new Fortescue possession, he replied: “We may do, however the choice isn’t just right down to us.

“By means of the connection with Liebherr, the intention is to supply actually aggressive merchandise which can be out there to different mining corporations, whether or not or not it’s Anglo, Vale or BHP, for instance…Absolutely the intention is to not give you a improvement or product that’s only for Fortescue.”

On this respect, he likens FMG to Tesla in the way in which the electrical automotive producer has acted because the catalyst to essentially change the automotive sector’s electrification strategy.

“Tesla, at the moment, is nowhere close to being thought of a big automotive producer by {industry} requirements, however they’ve created a catalyst for everyone else to maneuver from by way of battery-powered vehicles,” Wilson mentioned.

“They’ve virtually coerced the remainder of the producers to maneuver this fashion; you solely want to have a look at VW Group now – one of many world’s largest automotive makers – that’s committing the vast majority of its enterprise in direction of electrification.

“The distinction with Fortescue is it’s each the operator of those autos in addition to the proprietor of the expertise (via WAE). It’s creating these merchandise to make use of them, placing its complete enterprise on the road.”

This extends so far as its personal mining operations and the way it can optimise the pit profile and infrastructure to learn from all the benefits anticipated to come back with battery-electric haulage.

“Each the Fortescue mine planning and decarbonisation groups are working hand-in-hand with us to develop a mine website for the way forward for electrical mining,” Patterson mentioned. “We’re working collectively to reply the questions on what wants to alter to function these vans to maximise uptime, the place to place the charging factors, find out how to optimise the charging, and so forth.

“That work goes to be actually essential for us by way of creating a business answer that gives the sustainable positive aspects over the long run and decarbonises your complete fleet.”

Even when factoring in a mission that takes ‘stretch targets’ to a brand new degree, that’s reliant on sourcing elements from an evolving electrification provide chain, and that’s scheduled to see options arrive inside three years of discovering an OEM companion within the type of Liebherr, it’s laborious to doubt WAE, FMG, FFI and (after all) Andrew Forrest from steering such a mission via to the end line.

After that, it’s a matter of the remainder of the {industry} catching up.
