TL;DR: In this article, the safety and economic impacts triggered by poorly understood key processes are identified, such as the formation of corrosive hydrogen sulfide gas, hydrogen loss due to the activity of microbes or permeability changes due to geochemical interactions impacting on the predictability of hydrogen flow through porous media.

TL;DR: In this paper, the authors review the controls on the three major hydrogen consuming processes in the subsurface, methanogenesis, homoacetogenesis, and sulfate reduction, as a basis to estimate the risk for microbial growth in geological hydrogen storage.

TL;DR: In this article, the authors investigated the role of cushion gas, one of the main cost uncertainties of hydrogen storage in porous media, and concluded that a thorough investigation into the cushion gas requirement, taking into account cushion gas costs as well as the cost-benefit of having cushion gas in place, should be an integral part of a hydrogen storage development plan in saline aquifers.

TL;DR: In this paper, a hydrogen storage site selection tool for depleted gas or oil fields (DOGF) is proposed. But, the authors focus on the three major hydrogen consuming processes in the subsurface, methanogenesis, homoacetogenesis, and sulfate reduction, and only three fields can sustain all of these processes, due to either temperature, salinity or pressure constraints.
