Zero Carbon Lithium company Vulcan acquires geothermal plant; brine offtake agreement with geox

Vulcan Energy Resources has agreed to acquire an operational geothermal renewable energy power plant in the Upper Rhine Valley at Insheim, Germany, through the acquisition of 100% of the shares in the entity which owns and operates the plant. A new Germany subsidiary of Vulcan, based in Karlsruhe, will be the owner and operator of the Insheim Plant.

Purchased for approximately €31.5 million, utilizing a portion of proceeds from the recent A$200-million capital raise, the acquisition of the Insheim Plant establishes Vulcan as an operational renewable energy business.


The geothermal power plant in Insheim, Upper Rhine Valley, Germany.

Owned by regional energy supplier Pfalzwerke AG, the plant currently has the technical ability to produce a maximum of 4.8MW renewable power, equivalent to approximately 8,000 households, with an additional ability to produce heating. The plant is producing 2.9 MW of electricity on average.

Vulcan expects the Insheim Plant will be a source of revenue, as it reported sales of €5.8 million and an EBITDA of €2.9 million for the financial year ending 31 December 2020. The plant presently capitalizes on the Feed-in Tariff for geothermal power.

The acquisition also includes 100% ownership of the Insheim production licence surrounding the Insheim Plant. Following an MoU signed in November 2019, Vulcan had already completed the Maiden Indicated Lithium-Brine Mineral Resource Estimation at the Insheim license in January 2020, reporting an Indicated Mineral Resource of 722,000 t of contained Lithium Carbonate Equivalent (LCE), with a lithium brine grade of 181 mg/l Li.

The Insheim Plant currently pumps lithium-rich brine to the surface for geothermal energy generation before the brine is reinjected into the reservoir.

Vulcan will formally take over the plant from 1 January 2022 and will retain all existing local employees as part of the transition. Vulcan also plans to invest in the expansion and modernisation of the power plant.

The acquisition of the Insheim Plant is consistent with Vulcan’s strategy to acquire and upgrade existing brownfield renewable energy and brine infrastructure and to de-risk and grow our Zero Carbon Lithium Project. Funded with a portion of the proceeds from our recent $200 million capital raising, which was strongly supported by existing and new institutional investors, the acquisition demonstrates our willingness and ability to capitalise on strategic opportunities to ensure timely project development. This is a significant first step in establishing Vulcan as a revenue generating, renewable energy producer. German State and Federal policy increasingly supports decarbonizing heating and power grids, with a focus on decentralized, renewable energy, and Vulcan intends to build a number of distributed geothermal renewable energy plants across the Upper Rhine Valley region.

Combined with our brine offtake agreement with the Landau plant, we will work to assess the feasibility of integrating lithium extraction from these areas into our development plans. The Vulcan team remains focused on developing our world-first dual renewable energy and Zero Carbon Lithium business, with phase 1 production to supply the EU battery market targeted for CY2024.

Brine offtake. In addition to the acquisition of Insheim, Vulcan Energy has executed a 20-year brine offtake agreement with geox GmbH, the operational Landau geothermal renewable energy plant in the Upper Rhine Valley owned by the IKAV Group, a Luxembourg-based renewable energy fund manager and operator.

Under the terms of the agreement, Vulcan has the right to purchase and extract the lithium from the brine produced from Landau, and return it to the plant for re-injection, with expected brine volume from the production well of at least 100 l/s, subject to the financing and drilling of a re-injection well which can accommodate the current production well flow, and with an offtake start date of 30 December 2024.

The existing production well at Landau has the tested ability to produce at a rate of over 100 l/s, but an additional re-injection well is planned to help accommodate this flow.

In addition, subject to obtaining the relevant permissions from the authorities, the Landau plant will provide access to accommodate Vulcan’s demonstration lithium extraction plant, with a target start-up date of Q2 2022.

Vulcan has been successfully operating its first lithium extraction pilot plant at Landau since April 2021. Lithium grades in the brine from Landau well GTLA-1 are approximately 180 mg/l Li. Vulcan will seek, subject to positive feasibility studies, to incorporate this offtake agreement into its Phase 1 development plans.

The acquisition and brine offtake agreement positions Vulcan potentially to expand its Definitive Feasibility Study (DFS) and increase production in response to significant customer demand for sustainable lithium from its Zero Carbon Lithium Project.

Vulcan will assess the feasibility of extracting and processing lithium from these projects, as part of investment into an expansion and modernization of these areas, to be incorporated into planned operations. As a result, Vulcan is targeting completion of its Phase 1 DFS in H2 2022, updated from its previous target of mid-2022, to accommodate the inclusion of more project areas into expanded production studies. Vulcan’s target of first commercial production of lithium by 2024 remains unchanged.
