Details

This workshop explores advancements in sub-surface hydrogen storage and natural hydrogen exploration. Experts will discuss geological storage potential, geochemical interactions, microbial impacts, and innovative geophysical monitoring and exploration methodologies, providing insights into the challenges and opportunities in harnessing hydrogen for a sustainable energy future Hydrogen will play a crucial role in Europe’s energy transition towards a carbon-neutral society. The subsurface offers relatively safe and cost-effective options for storing hydrogen, supporting future energy hubs with enhanced energy security. Additionally, recent findings show that naturally produced hydrogen accumulations in the subsurface are a promising cheap/green resource for the hydrogen economy. This workshop explores advancements in subsurface hydrogen storage and natural hydrogen exploration. Experts will discuss the potential for geological storage in salt caverns, lined rock caverns, depleted oil and gas reservoirs, and aquifers. We welcome contributions at various scales, from laboratory studies focused on geochemical interactions observed in exposure or core flooding experiments to microbial studies under different pressure-temperature conditions and their corresponding effect on the petrophysical and geophysical properties, as well as large-scale case studies investigating future hydrogen production and storage networks. Innovative methodologies for hydrogen exploration and monitoring will be presented, along with new findings on the natural generation and trapping of hydrogen. Sub-Topics that will be covered in the workshop: Laboratory experimental set-up for hydrogen rock interaction Geophysical inversion methods to detect hydrogen-saturated rocks Case studies focusing on storage or exploration
