Geologic Storage of Hydrogen – Fundamentals, Processing, and Projects

Hydrogen production, storage, utilisation and environmental impacts: a review

“…In the context of the USHS system, the cyclic injection of hydrogen into (and possible retrieval from) a brine-filled permeable formation is part of multi-phase flow problems that have been studied extensively (Hashemi et al 2021;Liebscher et al 2016). In this case, a two-phase hydrogen-brine system is immiscible-the fluids are separated by a capillary interface.…”

Relative Permeability of Hydrogen and Aqueous Brines in Sandstones and Carbonates at Reservoir Conditions

“…When energy demand is lower than the amount of energy produced, the system operation can direct excess electrical energy to produce H 2 , which has a high energy density (Hassanpouryouzband et al, 2020). In order to establish regional or national hydrogen networks and to support the large-scale use of hydrogen, geological hydrogen storage can be a key enabler, providing the much-needed energy storage solutions at TWh scales (Liebscher et al, 2016). Geological subsurface formations not only have enormous storage capacity, but are also globally abundant, making geological storage of H 2 in porous rocks a cost-effective and efficient procedure.…”

Selection of Underground Hydrogen Storage Risk Assessment Techniques

“…We have less experience with underground hydrogen storage in porous geological formations. Practical applications are limited to storing town gas in aquifers (25-60% H 2 , 10-33% CH 4 , 12-20% CO and CO 2 and <30% N 2 ), e.g., in Beynes (France) or Lobodice (Czech Republic) [14,15]. The hydrogen-containing gas storage facilities are also located in depleted natural gas fields in Argentina (pilot project for hydrogen storage in the Diadema field) [16] and Austria (project "Underground Sun Storage" for storing gas containing 10% hydrogen) [9,17].…”
