Europe’s shift toward electrification and clean energy is often framed around renewable power projects, electric vehicles, and battery gigafactories. Yet behind these visible technologies lies a less discussed but equally decisive issue: where the minerals required for these systems will actually be processed.
Across key materials such as lithium, nickel, cobalt, graphite, and rare earth elements, Europe has begun to recognize that its most serious vulnerability does not lie in mining itself. Instead, the challenge lies in the intermediate stage between raw extraction and manufacturing—refining and materials processing.
This industrial layer, often described as the “missing middle” of the supply chain, has become one of the defining strategic challenges of Europe’s energy transition.
A Structural Gap in Europe’s Industrial Supply Chains
Europe is home to some of the world’s most advanced automotive, engineering, and renewable-energy industries. The continent leads in areas such as wind turbine manufacturing, electric vehicle development, and advanced battery production.
However, the upstream supply chain feeding these industries remains fragile. In many cases, Europe exports raw mineral concentrates or relies on imports of refined materials from Asia, particularly China, which dominates global processing of several critical minerals.
This imbalance has raised serious concerns among policymakers and industry leaders. Without domestic refining capacity, Europe’s high-tech industries remain exposed to supply disruptions, trade tensions, and geopolitical pressure.
The EU’s Strategy to Build Domestic Processing Capacity
In response to these risks, the European Union introduced the Critical Raw Materials Act, a new policy framework designed to strengthen supply-chain resilience.
Under the legislation, the EU aims to ensure that by 2030 at least 40 percent of critical minerals consumed in Europe are processed within the region. The policy also targets 25 percent of supply coming from recycling and limits dependence on any single external supplier to no more than 65 percent.
Achieving these goals will require a wave of refining plants, chemical conversion facilities, and advanced materials processing hubs across Europe—essentially building an industrial layer that historically has been missing from the continent’s resource economy.
Critical Minerals Power the Clean Energy Economy
The importance of refining capacity becomes clear when examining the materials needed for modern clean technologies.
Electric vehicles rely on lithium-ion batteries, which require large quantities of lithium, nickel, cobalt, manganese, and graphite. Offshore wind turbines depend heavily on copper wiring and rare-earth permanent magnets, while modern semiconductor devices require specialty metals such as gallium, germanium, and indium.
Without refining facilities capable of producing these materials domestically, Europe’s ambitious plans for electrification and digitalization remain vulnerable to global supply bottlenecks.
Estonia’s Rare Earth Processing Cluster
One of the most significant examples of Europe’s emerging refining infrastructure is located in Sillamäe, Estonia, where Neo Performance Materials operates the Silmet rare-earth separation plant.
The facility processes imported rare-earth concentrates and converts them into high-purity rare-earth oxides, which are used in magnets, electronics, and industrial catalysts. Currently, Silmet remains the only large-scale commercial rare-earth separation facility operating within the European Union, highlighting both its strategic value and Europe’s broader processing deficit.
Neo Performance Materials has recently strengthened this ecosystem by opening a permanent magnet manufacturing facility in Narva, also in Estonia. The plant is designed to produce around 2,000 tonnes of NdFeB magnets annually, with potential expansion to 5,000 tonnes per year.
These magnets are essential components in electric vehicle motors and wind turbine generators, making the Estonian cluster a key part of Europe’s emerging rare-earth supply chain.
France Builds a Rare Earth Refining and Recycling Hub
France is rapidly becoming another central node in Europe’s rare-earth processing landscape.
In La Rochelle, the Belgian chemical group Solvay operates a rare-earth processing facility that historically produced materials used in catalytic converters and specialty chemicals. In recent years, however, the plant has shifted toward producing neodymium-praseodymium (NdPr)—the key metals used in permanent magnets for electric vehicles and renewable energy technologies.
By the end of the decade, Solvay aims to supply 20 to 30 percent of Europe’s NdPr demand, helping diversify supply away from global processing centers. France is also developing Europe’s largest rare-earth recycling ecosystem. In Lacq, the company Carester is building the Caremag recycling facility, designed to recover rare-earth oxides from discarded magnets found in electric vehicles, wind turbines, and electronic equipment.
Once operational, the plant will produce approximately 1,400 tonnes of rare-earth oxides annually. The project involves around €216 million in investment, supported by both public funding and industrial partners. Nearby, the British company Less Common Metals plans to build a €110 million rare-earth alloy production facility, scheduled to begin operations around 2027. Together, these projects are expected to transform Lacq into Europe’s largest rare-earth refining and recycling hub.
Lithium Refining Becomes a Priority for Electric Vehicles
Beyond rare earths, lithium refining has become one of the most urgent priorities in Europe’s energy-transition supply chain.
Battery manufacturers require battery-grade lithium chemicals, including lithium hydroxide and lithium carbonate, produced through complex chemical conversion processes. While Europe hosts lithium resources in countries such as Portugal, Spain, Finland, and Austria, it has historically lacked sufficient conversion facilities.
To close this gap, several new refining projects are emerging. In Germany, AMG Lithium is building a refinery capable of producing 20,000 tonnes of battery-grade lithium hydroxide annually, supplying materials for European battery manufacturers. Additional projects are planned in Portugal and Finland, reflecting the rapid expansion of the European electric-vehicle supply chain.
Europe’s EV industry could require over 300,000 tonnes of lithium chemicals each year, making domestic conversion capacity a critical strategic priority.
Finland Leads in Battery Metals Processing
Finland has become a key player in Europe’s battery metals refining sector, particularly for nickel and cobalt, which are essential components of high-energy lithium-ion battery cathodes. Companies such as Terrafame and Boliden operate advanced refining facilities producing battery-grade nickel sulphate and cobalt sulphate, which are used in cathode manufacturing for electric vehicle batteries. These operations form part of a growing Nordic battery materials corridor, linking mining operations in Scandinavia with battery gigafactories located in Germany and Central Europe.
Graphite Processing: Another Strategic Weakness
Another critical gap in Europe’s supply chain lies in graphite processing, despite graphite being the largest component by mass in lithium-ion batteries.
Battery anodes typically require spherical graphite, which undergoes extensive purification and processing before use. Currently, roughly 90 percent of global graphite anode production occurs in China, leaving European battery manufacturers heavily dependent on imports.
To address this vulnerability, several companies are developing graphite purification and anode production facilities in Norway, Sweden, and Germany, aiming to supply Europe’s rapidly growing battery industry.
Copper and Semiconductor Metals Add to Supply Pressures
Electrification is also driving strong demand for copper, a metal essential for electrical systems. Electric vehicles require two to three times more copper than traditional combustion-engine vehicles, while renewable energy infrastructure depends heavily on copper wiring and transmission equipment.
Europe already hosts major copper refining operations in Germany, Poland, and Finland, but demand is expected to grow sharply as electrification accelerates.
At the same time, the semiconductor industry has highlighted the importance of specialty metals such as gallium, germanium, and indium, which are used in power electronics and photovoltaic technologies. Recent export restrictions by China on gallium and germanium have intensified concerns about Europe’s dependence on foreign suppliers.
Building the Missing Middle of Europe’s Supply Chain
Taken together, the growing network of rare-earth separation plants, lithium conversion facilities, battery-metal refineries, and recycling hubs represents the beginning of a European critical minerals processing ecosystem.
The challenge remains enormous. Even with the projects currently under development, Europe will continue to depend heavily on imported refined materials for much of the next decade.
China’s dominance in critical mineral refining was built over decades through massive investments in industrial infrastructure. Replicating that scale will require long-term planning, regulatory coordination, and significant capital investment.
The Infrastructure Behind Europe’s Energy Transition
Despite these challenges, Europe’s strategy is clearly shifting. Instead of relying entirely on global supply chains, the continent is gradually building its own processing capacity. From rare-earth facilities in Estonia to recycling and refining hubs in France, lithium conversion plants in Germany and Finland, and battery metals processing in Scandinavia, Europe is slowly constructing the industrial backbone needed to support its energy transition.
The transformation reflects a deeper realization: the clean-energy revolution is not only about technology but also about materials and supply chains. Wind turbines, electric vehicles, and digital infrastructure may represent the visible face of decarbonization. Yet the true foundations of this transition lie in the complex networks of refining plants and materials processing facilities that transform raw minerals into the building blocks of modern technology.
Over the next decade, these facilities will determine whether Europe can secure the materials needed for its energy transition—or remain dependent on external supply chains for the resources that power its future.
