From Lab to Literature: HyDRA’s Latest Papers Published

The HyDRA project is excited to announce its latest peer-reviewed scientific publications:

“Biogeochemical Interactions and Their Role in European Underground Hydrogen Storage” by Frank E. Viveros Acosta, Dr. Na Liu and Prof. Martin A. Fernø from the University of Bergen (UiB). The article is published in the Special Issue Mineral Dissolution and Precipitation in Geologic Porous Media.

This review explores how hydrogen interacts with reservoir minerals and microorganisms such as sulfate-reducing bacteria, methanogens, acetogens, and iron-reducing bacteria. These microbial processes can impact storage efficiency by consuming hydrogen, producing byproducts (H₂S, CH₄, acetate, Fe²⁺), and altering reservoir properties through biofilm formation and mineral reactions.

“Gas spreading and mixing in heterogeneous porous media for underground hydrogen storage” by Dr. Alejandro F. Visentini, Dr. Juan J. Hidalgo and Prof. Marco Dentz from Institute of Environmental Assessment and Water Research (IDAEA-CSIC) and Assoc. Prof. Luis Cueto-Felgueroso from Technical University of Madrid (UPM). The article is published in the International Journal of Hydrogen Energy.

Underground hydrogen storage efficiency depends on how gases spread and mix in porous rock. This study shows that greater reservoir heterogeneity leads to faster mixing but lower injection efficiency. Complex flow behaviors like gravity override and gas compression further affect performance, highlighting the need for tailored strategies in hydrogen storage design.
