Vulcan Frankfurt LiOH processing plant secures key permit in Germany

Vulcan Energy Resources

The Vulcan Frankfurt LiOH processing plant has cleared a major regulatory hurdle with its new German construction permit. The 24,000 t/yr lithium hydroxide monohydrate facility will sit in Frankfurt and anchor Vulcan’s European battery strategy. As a result, the Vulcan Frankfurt LiOH processing plant moves closer to supplying regional cathode and EV manufacturers with local low-carbon lithium.

Vulcan plans to fund the Vulcan Frankfurt LiOH processing plant during July–December 2025. However, the company must raise sufficient capital by 31 December to retain €104mn in German government grants awarded in late July. This deadline adds urgency to financing discussions and underscores Berlin’s support for EU battery value chains. Vulcan will feed the plant with lithium chloride from its Landau extraction project in southwest Germany, creating an integrated domestic supply route.

Offtake-backed model underpins Vulcan’s project financing

Long term offtake contracts provide a strong commercial base for the Vulcan Frankfurt LiOH processing plant. Vulcan has committed 182,000t of LiOH over ten years to LG Energy Solutions, Umicore and Stellantis. Therefore, a significant portion of future output is already locked into Tier-1 battery and automotive customers.

In addition, Vulcan is negotiating a fourth offtake deal it expects to sign by year end. This additional contract should further support project finance discussions with lenders and strategic investors. Meanwhile, Stellantis has already backed the Frankfurt plant through a $50mn equity investment in 2022, becoming Vulcan’s second-largest shareholder. This mix of offtake, strategic capital and grants gives the project a diversified funding stack.

Frankfurt LiOH plant targets 2027 start within EU battery buildout

Project timelines show how the Vulcan Frankfurt LiOH processing plant fits into Europe’s broader battery expansion. Vulcan began producing LiOH at a Frankfurt demonstration plant in November 2024 to de-risk technology and qualification. The company now targets commercial production at the full-scale facility in 2027, subject to successful financing.

Meanwhile, the integrated Landau–Frankfurt flow sheet aims to deliver lower-carbon lithium to EU customers. This is increasingly important as battery passports, ESG scoring and local content rules shape sourcing decisions. Therefore, the Vulcan Frankfurt LiOH processing plant could become a flagship European lithium hub if execution stays on track.

The Metalnomist Commentary

Vulcan’s progress confirms that offtake-backed lithium chemicals projects with strong policy support remain bankable, even in a volatile capital market. The key test now is whether Vulcan can close funding in time to secure German grants and hit its 2027 start date. For cathode producers and OEMs, Frankfurt’s eventual ramp-up will be a critical signal for how fast Europe can localise strategic lithium chemicals.
