Successful completion of the hydrogeological and rock mechanics measurements in the Remlingen 18 borehole
The Remlingen 18 borehole was drilled for the planning and dimensioning of the new shaft facility to be constructed for the retrieval of radioactive waste.
On behalf of BGE, Solexperts test teams carried out hydrofrac stress measurements, dilatometer tests and hydraulic packer tests in the 900 m deep borehole to determine hydrogeological and rock mechanical parameters. The in-situ tests enabled high-quality data to be obtained under challenging geological conditions, so that the exploration objectives could be achieved.
July 2024, Forsthaus Bern geo-storage facility; CO2 injection to increase the storage volume
EWB (Energie Wasser Bern) operates a waste incineration plant, a wood-fired combined heat and power plant and a gas and steam combined heat and power plant at the Forsthaus energy centre. These plants generate electricity and heat. The heat produced is fed into the district heating network. The "geothermal storage" pilot project aims to store surplus heat and utilise it in the winter months. Solexperts is providing specialist staff and test equipment for the extensive geothermal storage test programme. In order to dissolve lime, CO2-saturated water is currently being injected, resulting in an increase in hydraulic permeability and storage volume. An elegant alternative to acidification.
July 2024, Einstein-Telescope
The Einstein telescope will be a world-leading measuring instrument for detecting gravitational waves. The suitability of the border region of the Netherlands, Belgium and Germany as a location for this ground-breaking measuring instrument is currently being clarified with an extensive geological investigation programme. Solexperts is currently carrying out the hydrogeological and rock mechanical borehole tests.
Underground observatory
In order to be able to carry out undisturbed measurements, the observatory with its three arms, each ten kilometres long, will lie 250 to 300 metres below the earth's surface. Gravitational waves are detected by constantly measuring the length of its three detector arms with sensitive lasers and vibration-free mirrors. A passing gravitational wave is recognised when these lengths change in a certain pattern. The Einstein telescope will be able to record thousands of times more gravitational waves than its predecessors.

29 January 2024: the "Natural Hydrogen" Trophy
On 29 January 2024 in Paris, two CNRS researchers, Ph. de Donato and J. Pirononin, were awarded the "Natural Hydrogen" trophy at the National Assembly under the patronage of Emmanuel Macron for the discovery of natural hydrogen deposits in Lorraine.
Above all, this discovery is a prime example of a successful link between the world of science (University of Lorraine and CNRS) and industry (Française de l'Energie - FDE, Solexperts). Our Regalor (REssource GAzière de LORraine) project, funded by Europe (ERDF), the State (Pacte Lorraine) and the Grand Est region with the FDE as an industrial partner, was originally focussed on a different problem: the exploration and extraction of coal seam gas in Lorraine.
We discovered native hydrogen not only by chance, but also because we developed new tools that allowed us to detect its presence in the Lorraine Carboniferous Basin. The public-private alliance in collaboration with the company SOLEXPERTS has led to two important technological innovations.
The first is a miniaturised monitoring probe called SysMoG™, which can be inserted into boreholes with a minimum diameter of 6 cm and is capable of continuously measuring the gases dissolved in geological formations down to a depth of 1500 metres. This probe is protected by a European patent, which was applied for in April 2023. The second probe is an exploration probe called GH2asBusters SysMoG™, designed for rapid gas exploration in open boreholes with a minimum diameter of 6.5 cm. Thanks to the SysMoG™ probe, we were able to establish a depth profile of the dissolved gases present in the Lorraine Carboniferous on the site of the commune of Folschviller (Moselle, Grand Est region).
December 2023, BBC reports on the hydrogen deposit in Lorraine discovered with the Solexperts SysMoG probe and the promising prospects with natural hydrogen as a future energy carrier.

12 September; Gas exploration in Lorraine continues
The GH2ASBUSTERS team is starting a campaign to prospect for dissolved gases underground on behalf of Française De L’Enérgie compagny in three boreholes in Lorraine. The first sample was taken at a depth of 950 m in a borehole deviated by more than 45°. The operation was carried out in less than 24 hours, using the SysMoG probe.

WORKSHOP: NATURAL HYDROGENE RESSOURCES IN THE ALPS – From Exploration to an Economic Production
Hydrogen will become very important in the energy transition from fossil to low-carbon and renewable energy sources. Currently, hydrogen is produced almost exclusively by technical methods that are very energy-intensive. Natural hydrogen has been successfully explored at various geological locations around the world and has great potential to become an important, additional energy source.
So far, several studies have been conducted that demonstrate the occurrence and potential economic use of natural hydrogen (see e.g. Gaucher, 2020, Zgonnik, 2020). The following video provides a good overview: https://vimeo.com/456641451.
There are also host rocks in the Alps where an accumulation of natural hydrogen can be assumed. The aim of this expert workshop is to identify and develop possible exploration and development strategies in the Alpine region.
The workshop will take place on Thursday 29 September 2022 at the IBI Euregio Competence Centre in Vahrn (Italy) and will be organised as a hybrid event.
