[Geodynamics] EGU General Assembly 2025 session: Natural Hydrogen/Helium systems: scientific challenges and future resource perspectives

Dear colleagues,

The role of natural hydrogen (a.k.a. "geological", or "white" hydrogen) as a potential major contributor to a decarbonized energy system in the future has sparked significant debate in recent years. Geological helium resources, independent of co-production with fossil fuels, have similarly attracted the attention of both scientists and industry professionals, especially when co-located with hydrogen.

To date, a truly interdisciplinary scientific understanding of the subsurface natural hydrogen/helium system is lacking, with knowledge being fragmented across disciplines, and exploration/assessment workflows in their infancy. This session aims to address key subsurface aspects of geological hydrogen/helium systems, soliciting contributions from a broad range of disciplines, covering solid earth geosciences, geochemistry, hydrology, remote sensing and soil system sciences. In particular, the session aims to address:

- Generation potential and migration/possible accumulation processes and fluid pathways
- Geological history of such systems through the Wilson cycle
- Source rock/origin and conversion kinetics, flux estimates and relation to emplacement/host environment through geological time
- Spatial characteristics of geological hydrogen/helium systems - distribution, 3D geometry and their activity through geological time.
- Measurement and instrumentation aspects to detect, characterize, and quantify source, fluxes, shallow subsurface interactions and surface leakage of H2 and He.
- Natural hydrogen/helium occurrences and recent discoveries

We're very happy to have Prof Chris Ballentine (U Oxford) as solicited speaker for this session (https://url.au.m.mimecastprotect.com/s/qALvCXLW2mUM7yrlgF6f2IWNOLt?domain=earth.ox.ac.uk).

Looking forward to having you contributing to an exciting session and seeing you in Vienna in 2025.

Best,
Christian Heine (Shell, NL), Annick Loschetter (BRGM, FR), Meike Bagge (BGR, DE), Rodolfo Christiansen (LIAG, DE)
