Key challenges for underground hydrogen storage – pv magazine International
An international research team has presented challenges and knowledge gaps in the implementation of large scale underground storage of hydrogen. The main issues associated with this technology relate to the fluid flow behavior of hydrogen in subsurface reservoirs, geochemical reactions caused by hydrogen injection, biotic reactions caused by excess hydrogen, and the geomechanical response of the subsurface to hydrogen storage.
