Cushion gas replacement on underground gas storage in a naturally fracture aquifer: Cushion gas strategies for matrix-independent storage

Results in Engineering
Energy supply has become a critical global concern. Due to its low cost and high heating value (HV), natural gas is a leading energy source. However, its consumption fluctuates throughout the year due to varying heating demands in different weather ...

Utilization of CO₂ as Cushion Gas for Depleted Gas Reservoir Transformed Gas Storage Reservoir [PDF]

Energies, 2020
Underground gas storage reservoirs (UGSRs) are used to keep the natural gas supply smooth. Native natural gas is commonly used as cushion gas to maintain the reservoir pressure and cannot be extracted in the depleted gas reservoir transformed UGSR, which

Hydrogen and Cushion Gas Adsorption-Desorption Dynamics on Clay Minerals. [PDF]

ACS Appl Mater Interfaces
Transitioning toward a hydrogen (H2)-centric energy paradigm necessitates understanding the adsorption properties of clay minerals, essential constituents of reservoirs and caprocks, for efficient geological H2 storage. This study examines the adsorption characteristics of H2 on various clay minerals (montmorillonite, illite, chlorite, kaolinite, and ...

Hydrogen Storage in Deep Saline Aquifers: Non-Recoverable Cushion Gas after Storage

Energies
Underground hydrogen storage facilities require cushion gas to operate, which is an expensive one-time investment. Only some of this gas is recoverable after the end of UHS operation.

Hydrogen storage in saline aquifers: The role of cushion gas for injection and production

International Journal of Hydrogen Energy, 2021
Abstract Hydrogen stored on a large scale in porous rocks helps alleviate the main drawbacks of intermittent renewable energy generation and will play a significant role as a fuel substitute to limit global warming. This study discusses the injection, storage and production of hydrogen in an open saline aquifer anticline using industry standard ...

A Review of the Utilization of CO2 as a Cushion Gas in Underground Natural Gas Storage

Processes
A cushion gas is an indispensable and the most expensive part of underground natural gas storage. Using CO2 injection to provide a cushion gas, not only can the investment in natural gas storage construction be reduced but the greenhouse effect can also be reduced.

Cushion Gas in Hydrogen Storage—A Costly CAPEX or a Valuable Resource for Energy Crises?

Hydrogen, 2022
The geological storage of hydrogen is a seasonal energy storage solution, and the storage capacity of saline aquifers is most appropriately defined by quantifying the amount of hydrogen that can be injected and reproduced over a relevant time period ...
