Vulcan Energy Launches Civil Construction for 30MW Lionheart Geothermal Power Plant in Germany

Vulcan’s Role in Strengthening Europe’s Energy and Critical Materials Supply

Positioned at the nexus of Europe’s energy transition and battery supply chain security, Vulcan Energy Resources is developing the Lionheart project as a "lighthouse project for Europe's energy and critical raw material resilience." This underscores the strategic importance of domestic lithium production for European energy independence and electric vehicle manufacturing. Situated in the Upper Rhine Valley Brine Field along the Germany-France border, the project leverages decades of geothermal resource exploration and lithium-rich brines.

The company’s integrated operational model combines lithium extraction with geothermal energy generation, producing renewable baseload power and high-quality lithium chloride intermediates. This approach mitigates the high energy demands of lithium extraction by generating heat and power onsite from geothermal sources, enabling low-cost lithium production insulated from volatile energy prices. The commercial site spans approximately ten hectares within the Messegelände Südost industrial park in Landau, featuring infrastructure that connects well sites through an inter-connected pipeline and power (ICPP) network to transport lithium brine and industrial water.

Advancement of Civil Construction and Infrastructure Development

The start of civil construction marks a transition from bulk earthworks to intensive site development. Current activities include foundation preparation, concrete works for power plant buildings and equipment, and road infrastructure construction. These foundational steps set the stage for the subsequent building erection and process equipment assembly phases. The construction sequence reflects a methodical execution plan, with each phase building on prior groundwork.

Concrete layers are being laid as bases for the geothermal power plant foundations, signaling a move to substantial onsite building work. While the company has not disclosed the total contract value or specific timelines for completing civil construction, Managing Director and CEO Cris Moreno affirmed the project is "on time, and on budget," though baseline schedule and budget details were not specified.

Lithium Production Capacity and Impact on Battery Supply Chains

Designed to produce 24,000 tonnes of lithium hydroxide monohydrate annually, Lionheart will significantly bolster European battery manufacturing supply chains. This volume equates to approximately 500,000 electric vehicle batteries per year, based on Vulcan’s internal estimates of average EV battery size and chemistry in Europe as of the announcement date. The lithium hydroxide monohydrate produced will serve as an intermediate product for downstream battery-grade material processing.

The project produces a lithium chloride intermediate at the combined extraction and geothermal facility, which is then transported via the inter-connected pipeline and power network for further processing. Additionally, Lionheart aims to generate 275 GWh of renewable power and 560 GWh of heat annually for local consumers over its 30-year lifespan. This dual-revenue stream model monetizes both lithium production and excess geothermal heat, addressing European policy priorities for renewable energy generation and critical raw material security.

Geothermal Energy Generation and Heat Supply Integration

The geothermal component of Lionheart targets 275 GWh of renewable power annually, sufficient to meet lithium extraction energy needs and supply excess electricity to the grid or local industries. The project also plans to supply 560 GWh of heat annually to local consumers, creating an additional revenue source and integrating with regional energy infrastructure. The facility’s baseload geothermal energy production ensures consistent power availability, independent of weather or time, unlike intermittent renewables such as wind or solar.

By self-generating baseload heat and power, Vulcan asserts that Lionheart can deliver low-cost lithium production with resilience against high energy prices now and in the future. The geothermal resource is sourced from the well-established Upper Rhine Valley Brine Field, though specific technical parameters such as temperature and flow rates were not disclosed.

Project Progress and Executive Insights

CEO Cris Moreno highlighted the transition from preparatory earthworks to active civil construction, expressing satisfaction with the project's on-time and on-budget progress. He emphasized collaboration with project partners and committed to keeping shareholders informed as construction advances. While a milestone timeline chart was included in the announcement, detailed schedule and budget figures were not provided.

The announcement did not specify the identities of project partners, contractors, or joint ventures involved in Lionheart’s development.

Infrastructure Network Linking Well Sites and Processing Facilities

Lionheart features an inter-connected pipelines and power (ICPP) network linking geothermal well sites in the Upper Rhine Valley to the central processing facility in Landau. This network transports lithium brine and industrial water to the processing site and returns water for underground reinjection. It supports resource extraction, geothermal heat recovery, and waste management through integrated infrastructure. Although a significant capital investment, details on pipeline lengths, capacities, or costs were not disclosed.

The ICPP network bridges geographically separated lithium and geothermal resources with the central processing hub, distinguishing Lionheart from traditional lithium operations that separate water sources from processing facilities. Specific distances between well sites and the Landau facility and the number of planned production wells were not revealed.

Site Location and Industrial Park Context

The Lionheart commercial site occupies about ten hectares within the Messegelände Südost industrial park in Landau, Germany. The industrial park setting offers access to existing utilities, transportation, and regulatory frameworks. Landau lies in Rhineland-Palatinate, part of the Upper Rhine Valley known for geothermal resources and lithium-rich brines. The choice of an established industrial park aligns with regional economic and industrial development plans rather than remote greenfield development. No details on agreements with park operators or local authorities were provided.

The site encompasses the geothermal power plant, lithium extraction facility, and related infrastructure. Imagery included in the announcement shows the project layout and highlights civil construction areas. Being adjacent to urban areas may invite community and regulatory scrutiny, though the announcement did not address stakeholder engagement or environmental permitting.

Project Duration, Production Goals, and Long-Term Operations

Designed for an estimated 30-year operational life, Lionheart is a long-term production asset. The 24,000 tonnes per year lithium hydroxide monohydrate target corresponds to Phase One capacity, with additional phases planned as noted in prior communications. The battery equivalency of approximately 500,000 units annually is based on Vulcan’s internal estimates of average European EV battery size and chemistry as of this announcement, without accounting for future changes in battery technology.

The 30-year lifespan assumption supports the project’s economic model, reflecting expectations about resource availability, geothermal heat sustainability, and operational viability. The announcement did not disclose resource estimation methods, confidence levels, or sensitivity analyses related to reservoir performance. Reserve and resource details were referenced in earlier ASX releases.

Risks and Challenges in European Geothermal-Lithium Development

The Lionheart project faces multiple risks including subsurface technical challenges (reservoir characterization, production decline, induced seismicity), regulatory and permitting hurdles, market volatility (lithium prices, renewable energy conditions), and execution risks (construction delays, cost overruns, supply chain issues). The company’s forward-looking disclaimer notes that actual outcomes may differ materially from projections due to these factors and general economic conditions.

As one of Europe’s first integrated geothermal-lithium facilities, Lionheart carries technological and operational uncertainties inherent to emerging large-scale projects. While current progress is on time and budget, uncertainties remain regarding project completion, first production, and sustained operations.
