“…6). For example, the signicant presence of methanogens 44,131 and homoactogens, which consume free H 2 as an energy source, is essential in identifying potential storage formations and sites, which naturally harbor H 2 . On the other hand, the production techniques utilized for articially stored H 2 will probably be the same as natural H 2 .…”

“…The results show that the hydrogen-containing islanded microgrid can operate stably and optimally. Hydrogen storage technology and methods are constantly improving, and hydrogen energy can be stored underground [18] , such as in the usage of shale oil mines for hydrogen storage in the United States [19] . The seasonal energy storage of hydrogen energy supports a long time, large scale and wide spatial range energy transmission characteristics are the key technology to cope with the long time break of energy supply of high percentage renewable energy system [20] .…”

“…While controlling hydrogen cycling through injection rate can also change the subsurface multiphase fluid flow behavior, viscous fingering, fine migration, the mixing of store hydrogen with cushion gas, etc., they are more related to the storage performance rather than storage integrity. Therefore, the influence of hydrogen cycling on these aspects will not be discussed in this paper but are well summarized in other works [5,16,21,167].…”

The transition of energy from fossil fuels to renewable energy particularly hydrogen is becoming the centre of decarbonization and roadmap to achieve net-zero carbon emission. To meet the requirement of large-scale hydrogen storage as a key part of hydrogen supply chain, underground hydrogen storage can be the ultimate solution to economically store hydrogen thus meet global energy demand. Compared to other types of subsurface storage sites such as salt caverns and aquifers which are limited to geographical locations, depleted gas reservoirs have been raising more interest because of the wider distribution and higher storage capacity. However, safely storing and cycling of hydrogen in depleted gas reservoirs requires caprock, reservoir and wellbore to remain high stability and integrity. Nevertheless, current research on storage integrity during underground hydrogen in depleted gas reservoirs is still scarce and non-systemic. We therefore reviewed the major challenges on storage integrity associated with geochemical reactions, microbial activities, faults and fractures and hydrogen cycling perspectives. The processes and impacts of abiotic and biotic mineral dissolution/precipitation, faults and fracture reactivation and propagation in caprock and host-rock, wellbore instability due to cement degradation and casing corrosion, stress change during hydrogen cycling, etc. on storage integrity were comprehensive reviewed and analysed. Furthermore, a technical screening tool with consideration of controlling variables, risks and consequences on storage integrity was developed to identify the potential risks associated with storage integrity. Lastly, knowledge gaps together with feasible methods and pathways have been identified to mitigate the risks and thus enables large-scale underground hydrogen storage.
