6 FAQs about [Media hydrogen energy storage]

Is hydrogen storage in porous media safe and efficient?

Expectations for energy storage are high but large-scale underground hydrogen storage in porous media (UHSP) remains largely untested. This article identifies and discusses the scientific challenges of hydrogen storage in porous media for safe and efficient large-scale energy storage to enable a global hydro Energy Frontiers: Hydrogen

Is subsurface porous media hydrogen storage a viable option?

Subsurface porous media hydrogen storage could be a viable option to mitigate shortages in energy supply from renewable sources. In this work, a scenario for such a storage is developed and the operation is simulated using a numerical model. A hypothetical storage site is developed, based on an actual geological structure.

Is underground hydrogen storage in porous media underdeveloped?

The field of underground hydrogen storage in porous media is in many ways still underdeveloped, where knowledge gaps center on multiphase flow, mixing, and biogeochemical effects in porous reservoirs exposed to elevated H 2 concentrations and periodic injection-withdrawal cycles.

Is under-ground hydrogen storage a driver of the energy transition?

This perspective paper highlights a range of scientific issues that need to be addressed in order to enable large-scale under-ground hydrogen storage in porous media as a driver of the energy transition.

Can porous media hydrogen storage reduce a week-long gap in energy production?

5. Conclusion In this work, a basic scenario for porous media hydrogen storage was developed and the associated processes were simulated numerically using a realistic setting in Northern Germany. The investigated scenario resembles a case in which a week-long gap in energy production must be mitigated using energy storage.

Where can hydrogen be stored?

While hydrogen has already been stored successfully in salt caverns for industrial use in Texas, USA and Tesside, UK , experiences with subsurface porous media hydrogen storage are relatively scarce. So far only hydrogen-rich town gas has been stored in an aquifer near Baynes, France [1,2].
