Vulcan Energy Resources Starts Lithium Hydroxide Production at German Demonstration Plant

Vulcan Energy Resources

Lithium and geothermal group Vulcan Energy Resources has begun production of lithium hydroxide at its demonstration plant in Frankfurt, aiming for commercial production by 2027. This represents a two-year delay from its original timeline but positions Vulcan as a leader in carbon-neutral lithium extraction and processing.

From Pilot Production to Commercial Goals

Vulcan first started producing lithium chloride at its pilot extraction plant on April 8, 2024, and on December 21, initiated lithium hydroxide production using lithium chloride as feedstock. The demonstration plant has a capacity of 55 tonnes per year (t/yr), sufficient for regulatory compliance across at least three of the four required stages before commercial-scale operations commence.

The company plans to supply lithium hydroxide to key partners, including LG Energy Solutions, Umicore, Stellantis, Renault, and Volkswagen. As part of Phase 1 production, Vulcan aims to deliver 24,000 t/yr of lithium carbonate equivalent (LCE), enough for around 480,000 electric vehicles (EVs) annually, assuming an average EV battery capacity of 50kWh.

Low-Carbon Lithium Production with Geothermal Power

Vulcan employs direct lithium extraction (DLE) technology at its plant in the Upper Rhine Valley, achieving up to 95% efficiency — far higher than the 40-60% typical of traditional methods. By using geothermal brine to power extraction, the company eliminates fossil fuels from its processes, claiming the lowest carbon footprint in the global lithium production industry.

According to Cris Moreno, Vulcan’s CEO, the integrated upstream and downstream operations will produce lithium hydroxide without reliance on fossil fuels. "This allows us to provide affordable baseload heat and power, offering a sustainable and economically viable alternative," Moreno stated.

Challenges and Opportunities

Although Vulcan has twice delayed its commercial production schedule, its innovative approach to lithium extraction aligns with growing demand for sustainable materials in the EV market. Vulcan plans to create at least 1,300 direct and 1,500 indirect jobs upon reaching Phase 1 capacity.

However, the company has yet to complete a definitive feasibility study for Phase 2, which will further expand production and meet growing demand from global automakers and battery manufacturers.
