Why are fluid-rock reactions crucial for sustainably utilizing geotechnical potentials of the deep subsurface, and to tackle future energy challenges?

Sebastian Fischer
In recent years, the deep geological subsurface gained more and more attention as it offers various reservoirs potentially applicable for different geotechnical use options, e.g. deep geothermal energy, geological storage of CO2 and H2/energy. In this context, knowledge about the occurrence and the controlling processes of fluid-rock reactions in space and time is important to guarantee sustainable long-term reservoir utilization. While fluid-rock reactions occur at pore scale, they can significantly influence both reservoir-scale (transport) processes...

Latest Achievements with drill core scanning based on Laser Induced Breakdown Spectroscopy applied to 6 meter of drill core through Merensky Reef, Bushveld Complex, South Africa

Jeannet Meima , Dieter Rammlmair & Malte Junge
A 6-meter drill core from Merensky Reef, Bushveld Complex, South Africa, was scanned in detail with a drill core scanner based on Laser Induced Breakdown Spectroscopy. The purpose of the investigation was to visualize variations in the chemical composition along the core, and following a mineral classification of the LIBS data, of variations in the mineral chemical composition as well. The LIBS technology is based on atomic emission spectroscopy, in which the excitation of the...

Europe’s resilience on raw materials – how did GeoERA contribute

Antje Wittenberg , Daniel P. S. de Oliveira , Lisbeth Flindt Jørgensen , Tom Heldal & F. Javier González Sanz
Europe’s Green Transition is a declared key political goal in the European Union. The technology needed to achieve carbon neutrality by 2050 relies heavily on metals and minerals. Responsible sourcing and short travel distances of the required materials make a positive contribution to an environmental balance. In addition, raw materials make an important contribution to the well-being of a society. Hence, the United Nations sees raw materials as the key component for achieving all 17...

Mechanistic Insights of Mild Hematite Reduction in Hydrogen Storage Sites

Sonja Keller & Christian Ostertag-Henning
Hydrogen is a prospective energy carrier whose storage in extensive volumes is still an unsolved problem. One approach is underground hydrogen storage, in which geological formations such as salt caverns or depleted natural gas and oil reservoirs are used to hold large amounts of gas under pressure. However, in those formations minerals can react with the hydrogen stored and therefore deplete or contaminate the gas recovered. In our previous project we have shown that various...

An introduction to Landslide Susceptibility Assessment Tools - Project Manager Suite

Nick Schüßler , Jewgenij Torizin & Michael Fuchs
Landslide Susceptibility Assessment Tools - Project Manager Suite (LSAT PMS), an open-source, user-friendly program written in Python developed and released at the Federal Institute for Geosciences and Natural Resources (BGR). Although initially developed to conduct landslide susceptibility analyses, LSAT PMS is applicable for all types of spatial analyses related to supervised binary classification. The first LSAT PMS release supports analysis workflows based on the weight of evidence, logistic regression, artificial neural network, and analytical hierarchy...

Seismic Interpretation of a deltaic-fluviatil system within the Bückeberg-Formation (Berriasian, Lower Cretaceous, Lower Saxony Basin)

Matthias Warnecke & Gesa Kuhlmann
As part of the geothermal project GeneSys, the Federal Institute for Geosciences and Natural Resources, drilled the Groß Buchholz Gt1 geothermal well. At a depth of approx. 1,100 - 1,330m several sandstone layers of the Lower Cretaceous (predominantly Bückeberg Fm/Wealden) are present. Additionally to the borehole data, two seismic surveys covering the surrounding area (BGR 01-2001, 01-2006) were generated. For potential geothermal usage of these sandstone layers, their regional distribution within the larger Hanover area...

A systematic approach to develop recommendations for surface exploration of siting regions for a radioactive waste repository in Germany

Lisa Richter , Thies Beilecke , Raphael Dlugosch , Tilo Kneuker , Lukas Pollok , Nicole Schubarth-Engelschall & Ralf Semroch
The site selection procedure for a high-level radioactive waste repository in Germany is based on the Repository Site Selection Act (StandAG, 2017) and comprises three phases. Commissioned by the Bundesgesellschaft für Endlagerung mbH (BGE), the BGR contributes to this procedure with the projects „GeoMePS“ and „ZuBeMErk“, which aim to develop recommendations for phase 2 of the site selection procedure – the surface exploration of siting regions. For this purpose, the BGR has developed a systematic...
