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,

Remote Sensing During the 2025 Los Angeles Wildfires

AGU Advances, Volume 7, Issue 5, August 2026.
Abstract The January 2025 Los Angeles County wildfires burned more than 50,000 acres, destroyed more than 16,000 structures, and caused 31 deaths. This Commentary examines how NASA's Disasters Program coordinated with response organizations to deliver 22 satellite and airborne products during the fires, even as the Eaton Fire forced the Jet Propulsion ...

Savanna soil carbon accrual occurs through particulate organic matter from grass rather than tree biomass, regardless of atmospheric CO2 levels

Functional Ecology, Volume 40, Issue 8, Page 2532-2547, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Afforestation schemes in savannas are increasingly promoted as a carbon storage strategy despite threats to biodiversity. We also lack a clear understanding of how trees and grasses differentially contribute to the major carbon store in savannas, that is, soil organic ...
