Vulcan’s €2.2bn Lionheart Project Gets Green Light with Lithium Production Licence

A Milestone for European Lithium Production

Vulcan Energy Resources has achieved a significant regulatory breakthrough with the issuance of its first lithium production licence for the Lionheart Project, located in Germany’s Upper Rhine Valley Brine Field. This licence, the first of its kind in the region and the state of Rhineland-Palatinate, clears a major hurdle for Vulcan as it transitions from development to production.

The Lionheart Project is now fully funded, following a substantial €2.2 billion financing round completed in December 2025, and construction is underway. The project aims to produce 24,000 tonnes of lithium hydroxide monohydrate annually; enough to supply roughly half a million electric vehicle batteries each year. This scale positions Vulcan as a key player in Europe’s drive to secure a domestic, sustainable supply of critical battery materials.

Integrated Lithium and Renewable Energy Production

What sets Lionheart apart is its innovative integration of lithium extraction with renewable energy generation. Using geothermal brine from beneath the Upper Rhine Valley, Vulcan employs its proprietary VULSORB® technology to extract lithium while simultaneously producing renewable heat and power. The project is expected to generate 275 GWh of renewable electricity and 560 GWh of renewable heat annually, supporting local energy needs and reducing carbon emissions.

The lithium production licence, named LiThermEx, covers the Insheim geothermal permit area within Lionheart, which is already operational for renewable heat and power. This initial licence is granted for six years, with Vulcan planning to extend it to a 30-year term aligned with the project’s development plan, underscoring the long-term vision for sustainable lithium supply.

Strategic Implications for Europe’s Battery Supply Chain

Securing this licence is more than a company milestone; it represents a strategic advance for Germany and the European Union in their efforts to build resilience in critical raw materials and battery supply chains. With global competition intensifying for lithium; a key component in electric vehicle batteries; Vulcan’s progress signals a move towards reducing Europe’s dependence on imports and fossil fuel-based production methods.

Vulcan’s Managing Director, Cris Moreno, highlighted the importance of this achievement, thanking local authorities for their collaboration and emphasising the project’s role in delivering Europe’s first fully domestic lithium supply chain powered by geothermal energy. The Lionheart Project thus stands as a lighthouse initiative, combining innovation, sustainability, and industrial scale.

Looking Ahead

With construction underway and offtake agreements secured, Vulcan is on track to commence commercial production by 2028. The company also anticipates securing further lithium production licences for other areas within the Lionheart Project, which could expand its output and reinforce its position in the European battery materials market.

Investors and industry watchers will be closely monitoring Vulcan’s progress, particularly the extension of the LiThermEx licence and the successful integration of lithium extraction with renewable energy co-production. The project’s success could serve as a blueprint for sustainable critical materials production worldwide.
