UK gears up to produce rare earth magnets needed for electric cars

UK aims to cut dependence on China for super-strong magnets

Britain could revive domestic production of super-strong magnets used in electric vehicles and wind turbines with government support, it has been reported.

This would cut the UK's reliance on supplies from China and achieve vital cuts in carbon emissions, two sources told Reuters.

A UK government-funded feasibility study will be published on Friday, laying out the steps Britain must take to restart output of rare earth permanent magnets, the sources said.

A magnet factory would help Britain, currently hosting the Cop26 UN climate talks in Glasgow, Scotland, meet its goal of banning petrol and diesel cars by 2030 and slashing carbon emissions to net zero by 2050.

British production of the magnets ended in the 1990s when industry found it could not compete with China.

But with the huge growth in demand the government is keen to secure enough supplies.

Last month, the UK government set out plans to achieve its net-zero strategy, which includes spending £850 million ($1.15 billion) to support the roll out of electric vehicles and their supply chains.

The study outlines how a plant could be built by 2024 and eventually produce enough of the powerful magnets to supply 1 million EVs a year, the sources said.

“We're looking to turn the tide of shipping all this kind of manufacturing to the Far East and resurrect UK manufacturing excellence,” one source said.

The government's Department for Business declined to comment on details regarding a possible magnet factory because the report has not been released.

“The government continues to work with investors through our Automotive Transformation Fund to progress plans to build a globally competitive electric vehicle supply chain in the UK,” an official said.

EV ramp up

British rare earths company Less Common Metals put together the feasibility study and is considering seeking partners to jointly build the factory, the sources said.

LCM is one of the only companies outside of China that transforms rare earth raw materials into the special compounds needed to produce permanent magnets.

Car makers will need the magnets as they ramp up EV output in Britain.

Ford said last month it would invest up to £230m in an English plant to produce around 250,000 EV power units a year from mid-2024.

Magnets made of rare earth element neodymium are used in 90% of EV motors because they are widely seen as the most efficient way to power them.

Electric cars with these magnets require less battery power than those with ordinary magnets, so vehicles can travel longer distances before recharging.

A race by car makers to ramp up EVs and countries to switch to wind energy is due to boost demand for permanent magnets in Europe as much as tenfold by 2050, according to the EU.

The sources said government support would be vital so Britain could compete with China, which produces 90 per cent of supply.

The strategy mirrors similar efforts by the EU and the US to create domestic industries of raw materials, rare earth processing and permanent magnets.
