Study identifies the main scientific challenges of undergound hydrogen storage in porous media

Large-scale storage of hydrogen remains largely untested but is essential if hydrogen is to realize its potential to make a significant contribution to achieving net-zero emissions. A new perspectives paper sets out the key scientific challenges and knowledge gaps in large scale hydrogen storage in porous geological environments. These underground hydrogen reservoirs could be used as energy storages to face high demand periods. The article, authored by Niklas Heinemann and co-authored by GEO3BCN-CSIC researchers Juan Alcalde and Ramon Carbonell, has been recently published in the journal Energy and Environmental Science.
