Large‐Scale Hydrogen Storage: Surface and Subsurface Challenges
This review examines underground hydrogen storage with emphasis on the interaction between surface facilities and subsurface reservoirs. Variable renewable hydrogen requires compression, buffering, and purification before injection, while subsurface processes influence wellhead pressure, temperature, and composition.

Designing for Impact: Engaging Stakeholders With System Dynamics Models
ABSTRACT System dynamics models offer powerful tools for understanding complex systems and informing policy. Yet, their impact often falls short due to limited stakeholder engagement and poor implementation. Here, we explore how system dynamics models can be designed for real‐world impact by integrating analytical rigor, transparent modeling, and ...

Modeling Wind‐Driven Waves on Other Planets: Applications to Mars, Titan, and Exoplanets
Abstract Waves could exist on any planet with sustained winds and stable surface liquids. However, differences in atmospheres, liquids, and gravity confound efforts to extend Earth‐based empirical wave models to other planetary environments. We adapted a physics‐based numerical wave model to study how planetary conditions affect the growth of waves. We

ABSTRACT The COVID‐19 pandemic exposed the cascading and systemic nature of risks, in low‐income, multi‐hazard contexts such as Malawi, where pre‐existing vulnerabilities amplified impacts across health, economic, and social systems. This study draws on qualitative data from stakeholder workshops and key informant interviews, triangulated with national

Temperature and flow measurements on near-freezing aviation fuels in a wing-tank model [PDF]
Freezing behavior, pumpability, and temperature profiles for aviation turbine fuels were measured in a 190-liter tank chilled to simulate internal temperature gradients encountered in commercial airplane wing tanks.
