Europe’s plans for a self-sufficient battery supply chain are moving into a stage focused on whether the continent can fund, build and operate facilities that convert raw lithium into battery-grade chemicals. The shift is occurring as the lithium sector faces both strategic expectations and project-level economics tied to capital costs, feedstock access and long-term customers. In parallel, investors are responding to market conditions shaped by recent price declines.
Lithium demand growth contrasts with weaker pricing
Demand for lithium is supported by growth in electric vehicles, battery storage systems and renewable energy infrastructure. The International Energy Agency reported that global lithium demand increased by nearly 30% in 2024. Despite this expansion, prices have not recovered to earlier highs following the surge in 2021 and 2022.
Lithium prices fell sharply after the 2021-2022 peak period, losing more than 80% of their value from peak levels. The resulting environment has made it harder for new entrants to secure financing for large-scale projects. Investors have become more selective, prioritising projects that show economic resilience rather than those relying primarily on strategic narratives.
Battery-grade conversion becomes a key supply-chain constraint
Conversion is central to turning mined or brine-derived lithium into battery-grade lithium hydroxide used in high-performance EV batteries. Europe’s battery manufacturing plans depend on more than upstream production, with conversion capacity identified as a vulnerability in the regional supply chain. Where local conversion is limited, European manufacturers remain reliant on overseas processing networks, including those linked to Asia.
This dependency places lithium converters among the most strategically important assets in the battery ecosystem. The operational challenge is not only technical capability but also the ability to secure consistent feedstock and maintain plant utilisation over time. Financing and permitting therefore intersect with supply continuity requirements for conversion projects.
Germany’s Lionheart targets geothermal brines and renewable power
Vulcan Energy Resources’s Lionheart project in Germany’s Upper Rhine Valley is designed around geothermal brine extraction combined with renewable heat and power generation. The first phase is expected to produce approximately 24,000 tonnes of battery-grade lithium hydroxide annually. The European Investment Bank has stated that the project is designed to generate most of its own energy requirements and target net-zero emissions.
The project’s structure reflects an integrated approach that links resource extraction with chemical conversion while targeting a low-carbon profile. Its development has also reached a final investment decision supported by a financing package worth approximately €2.2 billion. The funding mix includes senior debt from multiple financial institutions, equity investments from industrial partners and public-sector financial support.
Critical minerals financing mix for large-scale conversion
The Lionheart financing package also includes strategic investors and government-backed financing mechanisms. The project illustrates how large-scale lithium conversion facilities are increasingly expected to combine public and private capital rather than rely only on traditional junior mining financing models. Long-term industrial partnerships and committed customers are described as part of the required structure for such projects.
Alongside Germany’s developments, France is also pursuing domestic integration through mine-to-chemical supply-chain initiatives aimed at producing battery-relevant intermediates within national boundaries. These efforts are tied to government support mechanisms intended to strengthen industrial policy objectives.
Imerys EMILI in France aims at integrated hydroxide production
Imerys’s EMILI project in France targets production of approximately 34,000 tonnes of lithium hydroxide annually. The output is described as sufficient to supply batteries for around 700,000 electric vehicles each year. The French government has committed financial support through a minority investment.
The EMILI project is positioned as an attempt to establish a fully integrated mine-to-chemical supply chain within a single country. It forms part of a broader regional push to localise key steps between raw materials and battery-grade chemicals rather than relying solely on external processing networks.
Rock Tech Lithium Guben converter advances permitted capacity
Rock Tech Lithium’s Guben Converter Project in Germany is described as fully permitted and designed to produce approximately 24,000 tonnes of battery-grade lithium hydroxide per year. The project has been recognised as a strategic initiative under the Critical Raw Materials Act. Cost optimisation efforts have reduced expected capital expenditures, improving commercial attractiveness.
The project progress is being monitored as a test case for Europe’s ability to build competitive lithium-processing infrastructure. Alongside these developments, conversion plants across Europe continue to face operational dependencies tied to raw-material sourcing.
Feedstock security remains linked to utilisation risk
Many European converters are expected to rely on imported feedstock including spodumene concentrate, lithium brines and intermediate lithium products. Without reliable access to raw materials, converters risk operating below capacity regardless of technical performance. Feedstock security has therefore become as important as financing and permitting for maintaining throughput.
This sourcing challenge affects how conversion assets can be valued over time when market conditions remain volatile. It also shapes how regional processing capacity may develop alongside upstream production and cross-border chemical supply arrangements.
Cathode active materials expansion extends beyond hydroxide
The regional battery strategy also covers materials beyond lithium hydroxide, including cathode active materials used in cell manufacturing. Orano and XTC New Energy developed the Neomat Cathode Active Material (CAM) project in Dunkirk. Backed by nearly €500 million, the facility is expected to produce 40,000 tonnes of cathode active materials annually.
The CAM output is described as supporting battery production for approximately 500,000 electric vehicles. This development reflects an expansion of localisation efforts beyond gigafactories into upstream material inputs required for battery manufacturing chains.
Localising multiple inputs remains central through 2030
The focus has shifted toward localising critical battery inputs such as lithium hydroxide, cathode active materials, battery precursors, graphite anodes and recycled battery metals. Without these components, gigafactories remain dependent on external supply chains that limit strategic autonomy. Dependencies across feedstock supply, battery chemicals, graphite processing and specialised materials are described as likely to persist well beyond 2030.
The scenario outlined for the remainder of the decade includes several globally competitive lithium-processing assets across Europe contributing to domestic capacity growth. Projects referenced include Vulcan Energy’s Lionheart, Rock Tech Lithium’s Guben Converter Project and Imerys’s EMILI initiative. However, complete elimination of reliance on imported materials is described as unlikely.
Investor criteria emphasise offtake terms and permitting pathways
The European lithium market is described as entering a more disciplined phase where investors reward projects that demonstrate long-term offtake agreements and secure feedstock supply. Additional criteria include realistic capital expenditure requirements, low-carbon energy sources and clear permitting pathways. Projects built primarily on strategic rhetoric are described as finding it harder to attract financing under these conditions.
The developments across Germany and France illustrate how conversion capacity planning depends on both industrial execution elements and structured funding approaches. In this context, converters are treated as key nodes linking raw-material availability with downstream battery chemical requirements across Europe’s manufacturing base.
Lithium remains a cornerstone of Europe’s battery strategy as one of the continent’s most important critical minerals. In the current market environment, possessing a resource alone does not address the need to convert raw materials into battery-ready chemicals while securing customers, managing costs and delivering projects on time. Europe’s progress toward battery independence is therefore tied to converters, refiners and processing plants brought into operation rather than upstream discovery activity alone.
