Vulcan Energy has officially started full-scale construction of its Lionheart lithium chemicals facility in Frankfurt, targeting a 2028 commercial production start with a capacity to supply 500,000 EV batteries annually.
- Construction begins at Frankfurt lithium chemical plant
- Lionheart targets 24,000 tonnes lithium hydroxide annually
- Project integrates renewable energy co-production
- €2.2 billion funding secured with positive Final Investment Decision
- Strong government and industry backing highlighted
Groundbreaking Marks Shift to Full-Scale Construction
Vulcan Energy (ASX:VUL, FSE: VUL) has transitioned from preparatory work to full-scale construction at its flagship Lionheart lithium chemicals plant in Frankfurt’s Infraserv Industrial Park Höchst. The event, marked by a ceremony attended by Hesse’s Minister-President Boris Rhein and Frankfurt’s Lord Mayor Mike Josef, signals a tangible step toward the company’s 2028 target for commercial lithium hydroxide monohydrate (LHM) production.
Designed to produce 24,000 tonnes of LHM annually, Lionheart’s output is expected to supply lithium for approximately 500,000 electric vehicle batteries each year. Alongside lithium production, the facility will generate 275 GWh of renewable power and 560 GWh of heat annually, reflecting Vulcan’s integrated approach to combining lithium extraction with renewable energy generation.
Financing and Strategic Support Cement Project Momentum
The company secured a €2.2 billion ($3.9 billion) funding package in December 2025, underpinning its positive Final Investment Decision for Lionheart. This financial backing has enabled Vulcan to proceed confidently with construction, following the earlier groundbreaking at its upstream lithium extraction plant in Landau. The project’s location in the Upper Rhine Valley Brine Field, straddling Germany and France, positions it as a key pillar in Europe’s critical raw material and battery supply chain resilience.
Vulcan’s Managing Director Cris Moreno emphasised the milestone, noting the strong collaboration with stakeholders to bring the Lionheart vision to life. This momentum follows Vulcan’s recent €40 million Siemens automation deal, which secured critical automation infrastructure and marked the completion of major supply contracts for the project.
Innovative Technology and Renewable Integration
Lionheart’s lithium extraction leverages Vulcan’s proprietary VULSORB® direct lithium extraction (DLE) technology, which taps into low impurity geothermal brines naturally heated beneath the Upper Rhine Valley. This process not only extracts lithium efficiently but also produces renewable energy co-products that support plant operations and supply surplus power to local consumers.
The downstream chemical plant in Frankfurt converts lithium chloride into battery-grade lithium hydroxide monohydrate through electrolysis, completing a vertically integrated supply chain within the region. Regulatory approvals are in place, allowing construction to advance without delay.
Europe’s Push for Domestic Lithium Production
The project’s high-profile support from government officials underscores Germany’s strategic intent to bolster domestic lithium production and reduce reliance on imports. Lionheart is positioned as a lighthouse project for Europe’s energy transition, aligning with broader regulatory incentives such as lithium royalty exemptions and critical raw material policies.
While Vulcan’s path forward is well capitalised and technologically advanced, the company’s forecasts and timelines remain subject to the usual risks inherent in resource development and construction projects. Market conditions, regulatory changes, and operational challenges could influence the pace and scale of production.
Bottom Line?
Vulcan’s Lionheart project has entered a critical construction phase, but its success will hinge on navigating complex operational and market risks ahead of its 2028 production goal.
Questions in the middle?
- How will Vulcan manage supply chain and construction risks to meet its 2028 production target?
- What impact will evolving European lithium demand and regulatory frameworks have on Lionheart’s commercial viability?
- Can Vulcan scale beyond Lionheart to maintain competitive advantage in Europe’s lithium market?
