The “Luftbrücke” license area is located in the northernmost part of the Vulcan Zero Carbon Lithium Project area and encompasses a number of industrial facilities including the Höchst Chemical Park and Frankfurt Airport. The City of Frankfurt aims to achieve carbon-neutrality by 2035 – no small feat considering that the city has a very carbon-intensive heat supply, 80% of which comes from gas and coal, serving a high heat demand in the range of 6-12 TWh per year.

This new licence and recent collaboration with the City of Frankfurt is a strong signal to renewable energy developers that Germany is unlocking demand for renewable heating to de-risk its reliance on foreign fossil gas.

“This new licence signifies a major future phase opportunity for Vulcan as a dual lithium and geothermal energy producer,” said Managing Director and CEO Cris Moreno. “We have a strong presence already in the region as we progress towards commissioning of our Central Lithium Electrolysis Optimisation Plant located in Höchst Chemical Park, which will also be the location of our Central Lithium Plant for our Phase One commercial operations. We look forward to growing our relationship with the Frankfurt region and its stakeholders to support their energy transition to meet their carbon neutral goals by 2035.”

Vulcan also reports investing in a joint research well in the region together with the City of Frankfurt, the Hessian Ministry of Economics, the LandesEnergieAgentur Hessen GmbH (LEA), the state geological survey, the BäderBetriebe Frankfurt GmbH, Mainova AG, the Leibniz Institute of Applied Geophysics (LIAG) and GLU Freiberg GmbH to test the heat and lithium concentrations. The well has been drilled, and brine sampling and analysis work is under way.

Vulcan is also assessing whether the high lithium concentrations in the Buntsandstein brine reservoir extend into the “Rotliegend” brine reservoir to the north under Luftbrücke.
