Deep geothermal energy represents a key element of future renewable energy production
due to its base load capability and the almost inexhaustible resource base. Especially with …

This paper presents the results of a revision of the data on terrestrial heat flow in Germany,
termed here as heat-flow density (HFD). The heat-flow values are considered as surface …

Geothermal projects in the Upper Rhine Graben aim to harness thermal anomalies that have
arisen due to hydrothermal circulation within the granitic basement and the overlying Permo …

Abstract The Upper Rhine Graben has a significant socioeconomic relevance as it provides
a great potential for geothermal energy production. The key for the utilisation of this energy …

Geohydraulic parameters, namely hydraulic conductivity (K), transmissivity (T), effective
porosity (ϕ), permeability (kp), anisotropy coefficient (λ), and longitudinal conductance (S), of …

Quantification of the systemic permeability of geothermal reservoirs is essential to the
assessment of their economic feasibility. Here we investigate experimentally the role of …

Geothermal energy exploitation in the Upper Rhine Graben (URG) chiefly has targeted faults
and fractures within or connected with the crystalline basement, where hot fluids of c. 200° C …

For an accurate multiscale property modelling of fractured crystalline geothermal reservoirs,
an enhanced characterisation of the geometrical features and variability of the fracture …

The extraction of rare metals like lithium (Li) from geothermal fluids is a promising alternative
to conventional mining. Membrane distillation (MD) could support energy-efficient fluid …

Lithium-rich brine plays a crucial role in the energy transition. Specifically, geothermal Upper
Rhine Graben brines and the fluid inclusions in the adjacent southwesternmost Black Forest …
