Renewable energy for the region Our Geothermal Heating Plant in Landau
The Landau geothermal heating plant plays a crucial role in our overall project. In addition to supplying heat to the existing district heating networks in Landau, the facility is also used for lithium extraction.
Currently, after heat has been extracted, the cooled thermal water is directed to our neighboring LEOP plant, where it is mainly used for testing and optimizing our lithium extraction process.
In the future, the geothermal wells will be connected via pipelines to the commercial lithium extraction facility located in the D12 industrial area of Landau, enabling lithium production on a larger scale.
The existing power generation facility will be dismantled. In the future, thermal energy that cannot be fed into the Landau district heating network will also be used in D12 for power generation.
Heat from Deep Underground: Geothermal Heating Plant in Landau Back in Operation
In Landau, climate-friendly district heating from geothermal energy is being supplied again: Vulcan’s geothermal heating plant resumed heat supply to EnergieSüdwest (ESW) on the morning of Monday, April 28, 2025. At the start, the facility delivers up to two megawatts of thermal output depending on demand—enough to supply households in the southern part of Landau with renewable energy.
With the gradual expansion of capacity, the district heating network is expected to operate almost climate-neutrally by 2026/27. From 2027 onward, parts of the city center are also planned to be connected to the network. Until now, the area has been predominantly heated with gas—the switch to geothermal energy will significantly reduce CO₂ emissions.
