TWENTY20 HYPOS JOINT PROJECTS: H2 UGS

According to current knowledge, salt caverns offer excellent conditions for the long-term storage of green hydrogen – from highly fluctuating processes such as power-to-gas. Building on this, the basic research-oriented joint project H2-UGS developed a standardised and transferable methodology for the future construction and conversion of salt caverns for hydrogen storage. These findings were summarised in a scientific based guideline for the site-independent assessment of caverns. This included issues on technical storage integrity and permitting.

UGS contributed to the research project by developing an overall technical concept for underground hydrogen storage, which incorporated the results of investigations in the fields of materials technology, geomechanics, and thermodynamics. This sub-project focused on designing underground components, setting testing and acceptance criteria, and developing evaluation methods to ensure a safe hydrogen storage. In four work packages, the defined well design standard for the key components of the entire process chain was developed specifically for underground hydrogen storage.
