EV Boom: How Rare Earths are Powering the Future – A GoldMinr Report

The electric vehicle (EV) revolution is in full swing, promising a cleaner, more sustainable future for transportation. But beneath the surface of this green revolution lies a critical dependency: rare earth elements (REEs). These obscure metals are the unsung heroes powering the high-performance motors that drive EVs, and understanding their role is crucial for investors and anyone interested in the future of the automotive industry. According to the International Energy Agency (IEA), demand for neodymium, a key ingredient in EV motors, is projected to rise by over 70% by 2030, highlighting the critical and complex nature of rare earth demand as the EV market accelerates.

The Unseen Engine: Rare Earths in Electric Vehicles

Rare earth elements are a group of 17 metallic elements with unique magnetic and luminescent properties. While they’re used in various high-tech applications, including wind turbines and consumer electronics, their role in EVs is particularly significant. Specifically, neodymium (Nd) and praseodymium (Pr) are essential for creating neodymium-iron-boron (NdFeB) magnets, the most powerful type of permanent magnet commercially available.

These magnets are the heart of Permanent Magnet Synchronous Motors (PMSMs), which have become the industry standard for EVs due to their efficiency, high torque output, and compact design. In 2024, PMSMs and Axial Flux Motors (which also rely on rare earth permanent magnets) made up over 86% of the EV motor market. Unlike induction motors, which are less efficient and bulkier, PMSMs provide the power and performance that consumers demand from their EVs. Dysprosium (Dy) and Terbium (Tb) are also used to enhance the performance of neodymium-based magnets, especially in high-temperature applications.

Forecasting Demand: A Rare Earths Crystal Ball

The demand for rare earth elements in EVs is skyrocketing. In 2024, rare earth demand from EV motors reached 37 kilotons, up 32% year-over-year, and is expected to rise to 43 kt in 2025. Projections from the IEA and Adamas Intelligence suggest dramatic increases in demand across battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), and hybrid electric vehicles (HEVs) through 2035. This surge is driven by improving technologies, falling battery costs, and government policies supporting electric transportation.

However, this increased demand also presents challenges. The rare earth supply chain is heavily concentrated in China, which controls over 80% of the market. This creates significant geopolitical risks and supply chain vulnerabilities for Western economies. As demand continues to rise, diversifying the supply chain and reducing reliance on a single source will be crucial.

The Environmental Impact: A Balancing Act

While EVs offer a cleaner alternative to traditional combustion engine vehicles, the mining and processing of rare earth elements can have significant environmental consequences. Traditional extraction methods involve removing topsoil, using chemicals to separate the metals, and creating leaching ponds. This process can lead to air and water pollution, erosion, and soil contamination. For every ton of rare earth produced, the mining process yields 13kg of dust, 9,600-12,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue.

In some regions, such as Baotou, China, rare earth mining has led to severe environmental damage, including soil incapable of supporting crops and contaminated water supplies. Abandoned mines pose ongoing hazards, with remaining chemicals leaching into groundwater and pools of wastewater potentially pouring into local waterways.

However, efforts are underway to mitigate these environmental impacts. Researchers are developing cleaner extraction methods using mildly acidic solutions and exploring ways to remove rare earths from waste coal ash. Recycling and reuse of rare earth materials are also gaining traction, offering a more circular supply chain that reduces the need for new mining.

Supply Chain Vulnerabilities and Geopolitical Concerns

The concentration of rare earth production in China raises concerns about supply chain security and geopolitical stability. China controls over 90% of global rare earth permanent magnet production, making manufacturers reliant on these components vulnerable to export restrictions and price volatility. In early April 2025, China imposed export restrictions requiring special government approval for exporting seven categories of medium and heavy rare earth metals, including terbium and dysprosium, which are critical for EV motor production. This measure has since escalated to a full suspension of exports until a new regulatory framework is established.

To address these vulnerabilities, countries like the United States, Australia, and Canada are working to diversify their supply chains and reduce their dependence on China. Initiatives like the U.S. government’s $2 trillion infrastructure proposal and Canada’s $2 billion critical minerals sovereign fund aim to boost domestic production and secure access to these essential materials.

The Future of Rare Earths in the EV Industry

As the EV market continues to grow, the demand for rare earth elements will remain strong. While some automakers are experimenting with magnet-free designs to reduce their reliance on these materials, PMSMs are expected to remain the dominant technology due to their efficiency and performance advantages.

Companies like MP Materials are strategically positioned to capitalize on this growing demand. MP Materials operates Mountain Pass, the sole scaled rare earth mine and processing facility in the United States, and is focused on creating a vertically integrated supply chain from mine to magnet.

However, the industry must also address the environmental and social concerns associated with rare earth mining. Sustainable extraction methods, recycling initiatives, and supply chain transparency will be crucial for ensuring that the EV revolution is truly green.

Navigating the Rare Earth Landscape: Advice for Investors

For investors looking to capitalize on the EV boom, understanding the rare earth landscape is essential. Here are a few key considerations:

Supply Chain Diversification: Look for companies that are actively diversifying their supply chains and reducing their reliance on China.
Sustainable Practices: Prioritize companies that are committed to sustainable mining and processing practices.
Technological Innovation: Keep an eye on companies that are developing new technologies to reduce the need for rare earth elements or improve their extraction and recycling.
Geopolitical Factors: Stay informed about geopolitical developments that could impact the rare earth market.

The EV revolution is transforming the automotive industry, and rare earth elements are playing a crucial role in this transformation. By understanding the dynamics of the rare earth market, investors can make informed decisions and capitalize on the opportunities presented by this rapidly growing sector.
