Cushion Gas Consideration for Underground Hydrogen Storage

Encyclopedia
Due to the increasing world population and environmental considerations, there has been a tremendous interest in alternative energy sources. Hydrogen plays a major role as an energy carrier due to its environmentally benign nature.

Recovery Factor of Pure Helium Injection in Depleted Gas Reservoirs and Its Influencing Factors

Energy Science &Engineering, Volume 14, Issue 8, Page 3922-3934, August 2026.
This study employs compositional numerical simulation to systematically investigate the effects of injection rate, production rate, storage duration, and injection‐production scheme on pure helium recovery in depleted gas reservoirs. Low injection rates reduce viscous fingering while high production rates maximize near‐wellbore helium extraction ...

Hydrogen‐Based Long‐Duration Energy Storage: Technologies, System Integration, and Techno‐Economic Performance

Global Challenges, Volume 10, Issue 8, August 2026.
Hydrogen‐based long‐duration energy storage (LDES) converts surplus renewable electricity into hydrogen through electrolysis, stores it using suitable storage technologies, and reconverts it into electricity, heat, or transport fuels. AI‐driven optimization, digital twins, and techno‐economic, environmental, and reliability assessments enable efficient,

Tides of the Midland: From Groundwater Into the River

Hydrological Processes, Volume 40, Issue 8, August 2026.
Tides in a river that is NOT influenced by the ocean, is not in the coastal area and is more than 300 m above sea level are caused by groundwater tides. As the phases of the Moon change, the amplitudes of the streamwater oscillations vary synchronously with those of gravitational acceleration.

Decoding the allosteric grammar of protein kinases: A dual‐stream framework integrating protein language models and energy landscape frustration analysis

Protein Science, Volume 35, Issue 8, August 2026.
Abstract The spatial and energetic encoding of allosteric regulatory sites remains a major challenge in structural biology, frequently representing a “blind spot” for sequence‐based artificial intelligence (AI) models. We present a protein language model (PLM)‐guided approach complemented by the energy landscape frustration analysis as a dual‐stream ...

Stress-sensitive porosity and permeability in carbonate rocks for underground hydrogen storage: A digital rock simulation study

International Journal of Coal Science & Technology
Hydrogen, a genuinely clean energy, is a promising alternative to fossil fuels. Inspired by underground gas storage of methane, establishing underground hydrogen storage (UHS) in depleted oil and gas reservoirs has emerged as a significant research focus.

Hydrogen Storage in Porous Rocks: A Bibliometric Analysis of Research Trends

Energies
Currently, there is an increasing number of research studies on underground storage of hydrogen in porous rocks (aquifers and depleted hydrocarbon fields). An important aspect of this process is the efficiency of hydrogen storage, which is defined as the

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.
