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 Storage in Deep Saline Aquifers: Non-Recoverable Cushion Gas after Storage
EnergiesUnderground 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
ProcessesA 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 ...

A review on underground gas storage systems: Natural gas, hydrogen and carbon sequestration
Energy Reports, 2023 The concept of underground gas storage is based on the natural capacity of geological formations such as aquifers, depleted oil and gas reservoirs, and salt caverns to store gases.

Liquid–solid impacts with compressible gas cushioning [PDF]
Journal of Fluid Mechanics, 2013 AbstractThe role played by gas compressibility in gas-cushioned liquid–solid impacts is investigated within a viscous gas and inviscid liquid regime. A full analysis of the energy conservation in the gas is conducted for the first time, which indicates that both thermal diffusion across the gas film and viscous dissipation play an important role in gas

Carbon Dioxide as Cushion Gas for Natural Gas Storage [PDF]
Energy & Fuels, 2002 Natural gas storage is used to smooth the natural gas supply to meet high peak demand. In natural gas storage, the working gas (methane) is injected and produced seasonally while a cushion gas that is not extracted is used to provide pressure support.
