Lithium prospectivity and capacity assessment in Northern Germany

• The estimated capacity across all target horizons is 4.73 Mt with a possible range of 0. 39 to 26.51 Mt of lithium metal. • The most promising resources are in the low-permeability Permian plays on the basin margins to the south and east. • Decoupling lithium production from geothermal energy production may be necessary and will require new frontier play concepts. Given the rapidly increasing demand for rechargeable batteries and the EU's net-zero targets, lithium is an important building block for the future energy economy, but resources in Germany are limited to unconventional deposits with unknown quantities. Here, we focus on lithium resources in northern Germany and assess their potential using a probabilistic volume approach. The estimated capacity across all target horizons is 4.73 Mt with a possible range of 0. 39 to 26.51 Mt of lithium metal. However, the most promising resources lie in the low-permeability Permian deposits and require new frontier play concepts.
