Energy Storage: Austrian Development of an integrated subsurface hydrogen storage system from lab to field pilot |
Dr. Marcus Pichler |
The lecture will be at Seismik (Kubišova 1265/8, Prague 8). In the light of a changing energy system that does already and will in the future contain even more renewable energy sources a subsurface gas storage facility seems to be a bit out of place. Therefore, RAG Austria AG already decided early on in 2013 to find ways how its assets could be of use in this renewable energy future. With the power to gas technology electricity can be converted into hydrogen which, could then possibly be stored in depleted gas reservoirs.

Expedition vulcano Litli-Hrútur 2023 |
Jeroným Lešner |
Mr. Lešner gave us an interesting lecture on vulcano Litli-Hrútur. He had made several expeditions in time of eruptions (2020 - 2023). He shared with us tips for observing active vulcanos on Iceland, we could see and touch rare samples of various forms of lava like Pele's tears and Pele's hairs and see his rich field trip inventory. |

Seismic imaging in hardrock environment:
challenges and a road ahead
|
Dr Michal Malinowski, Geological Survey of
Finland (GTK) / Institute of Geophysics PAS. |
Seismic methods are more and more often used for exploration in crystalline rocks (so called hardrock environment). However, standard seismic processing and imaging techniques are often
not able to properly handle the challenges imposed by the hardrock environment, e.g. strong
velocity contrasts in the shallow overburden, strong wavefield scattering or steeply dipping
structures. Despite problems related to building a reliable velocity model based on sparse
reflections, recent examples suggest significant uplift in imaging by using pre-stack depth
migration.
