Lionheart involves the construction of an integrated lithium and renewable energy project targeting production capacity of 24 000 t of lithium hydroxide monohydrate (LHM), enough for ca. 500 000 electric vehicle batteries per annum, with a co-product of 275 GWh of renewable power and 560 GWh of heat per annum for local consumers, over an estimated 30-year project life.
The signing of the Siemens Agreement represents the final major supply agreement for Lionheart. The balance of major works agreements were signed in the latter half of 2025.
Siemens will act as the Main Automation Contractor (MAC) for Vulcan’s upstream commercial Lithium Extraction Plant in Landau, already under construction, downstream Central Lithium Plant at Industrial Park Höchst, Frankfurt, and production well sites. This will include engineering and delivery of the distributed control system, industrial network and cybersecurity infrastructure, building automation, safety systems, and associated design and lifecycle services.
The Siemens Agreement follows a Memorandum of Understanding entered into by the Company and Siemens in 2025 to acknowledge Siemens as a preferred supplier until 31 December 2035, both for Lionheart and future phases of development. Siemens Financial Services has agreed to invest €67m as part of Vulcan’s €2.2bn (US$3.9bn) financing package secured in December 2025.
Vulcan Energy’s Managing Director and CEO, Cris Moreno, commented: “The signing of this framework agreement with Siemens AG builds on our established partnership with the broader Siemens group which shares Vulcan’s commitment to innovation and sustainability.
“We are pleased to be working alongside Siemens who have a vast local presence and history working in the broader region, and bring decades of experience in delivering engineering, automation, telecommunications, and digital technology systems to similar types of industrial projects.
With construction under way, the stage is set for Vulcan and our key partners to deliver our flagship Lionheart Project, which will deliver Europe’s first fully domestic and sustainable lithium supply chain”.
