In the first week of June, Alla Shogenova and Kazbulat Shogenov took part in the Annual EAGE 2025 Conference and Exhibition in Toulouse, southern France, one of the largest geoscientific events in Europe. Before the conference, the researchers took part in an excursion to natural hydrogen in the Pyrenees.

About 6,000 participants were registered for EAGE 2025, including 1,300 oral and poster presentations and 2,000 exhibitors. Energy transition was one of the most engaging themes and subjects for the presented technologies, research, workshops and field trips. CO2 capture, transport and storage, CO2 mineral carbonation in basalts, geothermal energy and associated lithium production, energy storage, natural hydrogen and associated helium production, as well as traditional geophysical and geological modelling were among the presented and discussed themes during the conference and associated events. The world’s most famous oil, gas, and geophysical companies demonstrated their full readiness to work towards climate neutrality and offered carbon-neutral options and technologies.

Unique geological settings and natural hydrogen sampling were demonstrated during a geological excursion in the Pyrenees. by Pr. Charles Aubourg (University of Pau and Pays de l’Adour) and Dr. Marc Blaizot (GEOLVAL) introduced many different geological features and rocks of various ages and genesis, including faults, salt diapirs, and nearly vertical layers of rocks. CVA company (Dr. Gille Fabre and Dr. Emmanuelle Baudia) demonstrated natural H2 sampling.

On the last day of the conference, Kazbulat Shogenov presented the poster (sponsored by the Estonian Ministry of Climate) „Game-changing CCUS technology – direct injection from a ship in the Baltic Sea (Shogenov, Shogenova, Berenblyum and Ostvedt)”, which sparked considerable interest among the poster session visitors.
