Vulcan Energy has reached financial close on its €2.2 billion Lionheart financing package, advancing one of Europe’s most closely watched efforts to establish a domestic lithium supply chain through an integrated geothermal production model in the Upper Rhine Valley between Germany and France.
The Lionheart development targets output of 24,000 tonnes per year of lithium hydroxide monohydrate, a volume equivalent to material for approximately 500,000 electric-vehicle batteries. Over a planned 30-year project life, the operation is also designed to generate about 275 GWh of renewable electricity and 560 GWh of heat as co-products.
Integrated geothermal lithium and energy production model
The Lionheart project is structured around a combined extraction and energy system, distinguishing Vulcan Energy from conventional lithium developers. Instead of relying solely on mining or standalone processing facilities, the company is producing lithium chemicals from geothermal brines while simultaneously generating renewable power and heat.
This dual-output configuration positions the project as both a battery materials production asset and an energy infrastructure development, integrating lithium supply with renewable energy generation within a single operational framework.
Construction and financing milestone progression
The financing milestone follows earlier project development steps, including securing financing arrangements, reaching final investment decision, and initiating construction in December 2025. With financial close now completed, Lionheart transitions into an execution-focused phase centered on construction delivery and operational ramp-up.
The project’s progression shifts investor focus toward commissioning performance, plant construction timelines, operational reliability, and the ability to achieve stated nameplate production capacity for lithium hydroxide monohydrate.
Strategic positioning within Europe’s battery supply chain
The Lionheart project is positioned within broader European industrial objectives aimed at reducing reliance on imported lithium and expanding domestic refining capacity for battery materials. It is also linked to efforts to establish lower-carbon supply chains for electric vehicle production. Located within Europe’s automotive manufacturing region, the project aligns with demand for localized sourcing and emissions-conscious supply inputs, reflecting industrial requirements across the regional EV supply ecosystem.
Execution phase focus on scale and product quality
With financial close completed on the €2.2 billion package, Vulcan Energy now faces execution requirements covering large-scale construction, commissioning, and production ramp-up. The project outcome will depend on the ability to deliver geothermal lithium production at industrial scale while maintaining battery-grade quality standards across its output streams.
