Three members of our Lendület Research Group — Márta Berkesi, Ákos Kővágó and Tamás Spránitz — spent the past two weeks in southern Spain as part of a Hungarian–Spanish collaboration, contributing to the H2RISE research project (Natural hydrogen and underground storage in rift-inversion systems).
The aim was once again to investigate fluid-flow systems, but this time the focus was not on CO2, but on the formation and migration pathways of H2. The research took place in the Ronda peridotites, the world’s largest exposed subcontinental upper-mantle complex. In addition to its spectacular scenery, the Ronda massif provides a unique opportunity to study the deeper layers of the continental lithosphere and to gain insight into the generation of geological hydrogen through peridotite–water interaction.
Together with colleagues from the Instituto Geológico y Minero de España (Geological and Mining Institute of Spain), members of our research group contributed to the collection of rock, spring-water and gas samples. We hope that the selected rock samples will also provide opportunities for fluid inclusion studies. The success of the fieldwork is reflected in the large number of samples collected.
This collaboration is, of course, only just beginning, and we look forward to sharing further developments in the future.
