Cost Analysis and Optimization of Green Hydrogen Production via Concentrating Solar Technologies and PEM Electrolyzer

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
The burgeoning demand for power across the globe and the disastrous effect of climate change that results from power generation through depleting unclean fuel sources have necessitated the use of renewable and clean fuels. Hydrogen is a good alternative but only when produced from low‐carbon energy resources.

Design and Validation of a Passive Solar Tracking Sensor Based on Gnomon Shadow Analysis

open access: yesInternational Journal of Photoenergy, Volume 2026, Issue 1, 2026.
Solar tracking is essential for efficiency, yet current market solutions present a trade‐off: Active systems are precise but expensive and computationally demanding, while low‐cost passive systems (e.g., LDRs) often lack accuracy. To address this gap, this work presents the design and validation of a passive solar tracking sensor based on gnomon shadow
