Focus: Automakers’ drive to keep away from China’s EV uncommon earth dominance gathers velocity

LONDON/BERLIN, Nov 14 (Reuters) – The auto trade’s drive to make electrical automobile motors with little to no uncommon earth content material has hit excessive gear, with European, U.S. and Japanese automakers and suppliers racing for options in an space dominated by China.
Automakers have principally relied on motors with uncommon earth-based everlasting magnets, which have been essentially the most environment friendly at offering the torque to energy EVs.
However various kinds of motors with out everlasting magnets that have been beforehand too huge and too inefficient, or these with greatly-reduced uncommon earth content material have develop into commercially viable, prompting the frenzy for options.
Market chief Tesla (TSLA.O) garnered headlines earlier this 12 months saying it might lower uncommon earths from its next-generation EVs.
However automakers from Common Motors (GM.N) to Jaguar Land Rover (JLR) and main suppliers like BorgWarner (BWA.N) are researching, or have developed, motors with low- to zero-rare earth content material akin to magnet-free externally excited synchronous machines (EESMs), which generate a magnetic discipline utilizing electrical present.
Others like Nissan (7201.T) are going additional than beforehand reported, with a twin technique to develop each newer EESM motors and in addition to develop everlasting magnet motors the place the uncommon earth content material will likely be steadily eradicated altogether.
China dominates the mining and processing of a gaggle of 17 metals generally known as uncommon earths, although corporations elsewhere are attempting to loosen China’s grip.
Latest Chinese language restrictions on exports of gallium and graphite – which is important for EV manufacturing – highlighted the chance of over-reliance on China.
German provider ZF (ZFF.UL) has developed an EESM motor that Chief Know-how Officer Otmar Scharrer stated matches the scale and efficiency of everlasting magnet motors.
“This is a crucial contribution to creating us a bit of extra impartial of China,” he stated.
ZF is in talks with U.S., European and Chinese language automakers to provide the motor and may very well be in manufacturing mannequin EVs inside two years, Scharrer stated.
Except for over-reliance on China, refining uncommon earths, akin to neodymium and dysprosium, includes solvents and poisonous waste that battle with sustainability targets.
“In case you get it proper, you’ve got obtained a way more sustainable product,” Ben Chiswick, director of engineering enterprise growth at Detroit-based Drive System Design, which is creating uncommon earth-free motors with three automakers.
Some automakers, like BMW (BMWG.DE) say they’re already there after years of analysis.
“It was not a house run… however it works very properly with out uncommon earths” stated Uwe Deuke, the engineer answerable for creating BMW’s EESM motor for its next-generation EVs.
‘WAITING IN THE WINGS’
The typical EV everlasting magnet motor makes use of round 600 grams (1.32 lb) of heavy uncommon earth neodymium. Costs have fluctuated significantly for neodymium – at round $125/kg now, it’s down from a peak of round $223 final 12 months, however properly above $65 in 2020.
Vitesco (VTSCn.DE) designed an EESM motor for Renault (RENA.PA) and has a brand new model coming in 2026. Gerd Roesel, innovation head on the German provider’s electrification division, stated uncommon earth-free options keep away from these wild value swings.
Others like U.S. startup Niron Magnetics are creating everlasting magnets with out uncommon earths.
Tesla’s announcement on dropping uncommon earths “opened up patrons’ eyes to the truth that you do not actually need uncommon earths to make EV magnets,” Niron CEO Jonathan Rowntree stated.
Niron’s newest funding spherical included investments from GM and Stellantis (STLAM.MI).
Nissan makes use of an EESM motor in its Ariya crossover. Shunji Oki, knowledgeable chief on the automaker’s powertrain and EV engineering division, stated Nissan is creating each higher EESM motors and everlasting magnets the place uncommon earths will likely be phased out.
James Edmondson, an analyst at consultancy IDTechEx, stated automakers rushed to search out options as uncommon earth costs rose, however now costs have fallen they’re watching China carefully and ready to see if governments take motion that will curb using Chinese language uncommon earths, because the U.S. Inflation Discount Act did.
“Because of this they (automakers) produce other applied sciences ready within the wings,” he stated.
IDTechEx forecasts that as of now rare-earth everlasting magnet motors will lose some world market share over the following decade however nonetheless make up greater than 70% as Chinese language EV makers face no strain to curtail their use – although their share will likely be a lot nearer to 50% in Europe, Edmondson stated.
And the place western automakers are sticking with rare-earth everlasting magnets, they’re working to dramatically cut back their content material, he added.
Mercedes-Benz’s (MBGn.DE) next-generation EV platform, as an example, has virtually no heavy uncommon earth content material.
The problem additionally goes past motors.
In some EVs, round a 3rd of the uncommon earths used are within the sound system’s audio system. UK agency Warwick Acoustics has developed uncommon earth-free audio system which can be 90% lighter and extra vitality environment friendly than standard ones. It has signed up its first luxurious automaker buyer and is speaking to others, CEO Mike Grant stated.
“We’re combating off individuals proper now,” he stated.
