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.The underground storage of hydrogen has been pointed out by recent research as a feasible solution to contribute to the creation of a hydrogen economy in several world regions. ...Den vollständigen Artikel lesen ...
