Techno‐Economic Assessment of a Hydrogen‐Assisted Hybrid Renewable Microgrid with Fuel Cells for Off‐Grid Electrification

Global Challenges, Volume 10, Issue 6, June 2026.
This study presents a hydrogen‐assisted hybrid renewable microgrid optimized using HOMER Pro for off‐grid electrification in coastal Bangladesh. Integrating solar PV, wind, BESS, electrolyzer, hydrogen storage, and fuel cells, the system achieves a low cost of energy ($0.139/kWh), high reliability, and near‐zero emissions, offering a sustainable and ...

Oases of endemism: Regional aquifer desert springs serve as biodiversity hotspots preserving vulnerable endemic taxa in the Great Basin and Mojave Desert regions

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Spring ecosystems in arid regions often serve as crucial biodiversity hotspots by providing some of the only reliable sources of surface water. However, anthropogenic activities and climate change have severely degraded spring ecosystems worldwide, emphasizing the need for large‐scale multidisciplinary studies informing conservation efforts ...

Conditions leading to exceptionally high temperatures in shallow tropical lakes

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Factors leading to exceptionally high temperatures in shallow tropical waters are examined with high‐resolution measurements and application of a 3‐dimensional hydrodynamic model in an Amazon floodplain lake. Highest near‐surface (0.05 m) temperatures in open water ranged from 31.0 to 37.5°C. Within mats of floating plants maximum temperatures

Enhanced geothermal systems (EGS): A review

Renewable and Sustainable Energy Reviews, 2016
Abstract Geothermal energy is a renewable energy source that can be found in abundance on our planet. Only a small fraction of it is currently converted to electrical power, though in recent years installed geothermal capacity has increased considerably all over the world.

Adaptive Hierarchical Fracture Model for Enhanced Geothermal Systems

Multiscale Modeling & Simulation, 2016
Summary: In enhanced geothermal systems, cold working fluid (usually water) is injected into a fractured reservoir to enhance the efficiency of the power plant by increasing the conductivity of existing fractures and by creating new ones. For the modeling of single phase flow and transport in such dynamically changing fractured reservoirs, a new ...
