Vulcan’s Lionheart lithium project: regulatory milestone and design notes for engineers
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Vulcan Energy has secured a key German regulatory milestone for its Lionheart lithium project, clearing a major hurdle towards bringing geothermal brine–sourced lithium chemicals into commercial production in the Upper Rhine Valley. The project targets direct lithium extraction from deep geothermal reservoirs, integrating baseload renewable power and heat with lithium hydroxide output for European battery supply chains. For geotechnical and civil teams, the approval signals advancing timelines for drilling, wellfield development and surface plant construction in a densely populated, infrastructure-rich setting with strict environmental constraints.
Technical Brief
- Project design couples deep geothermal production wells with reinjection wells, requiring closed-loop brine handling.
- Co-production of heat and power will influence well spacing, flow rates and surface plant layout.
- Integration with European battery supply chains implies high product purity control and stable long-term throughput.
Our Take
ABB’s mandate to deliver the full electrical infrastructure for the Lionheart geothermal lithium project points to a highly integrated power and process design, which should help Vulcan Energy control operating costs and decarbonisation performance compared with conventional hard‑rock lithium operations in Australia.
Within our 1093 Mining stories, lithium appears frequently in Europe‑focused sustainability pieces, and Lionheart’s progression in Germany positions Vulcan Energy as one of the few lithium developers in our coverage combining geothermal power and chemical production at commercial scale in the EU.
