The Hydrogen Stream: Chile selects electrolyzer companies for local assembly
Chile’s economic development agency Corfo has selected three companies – two Chinese and one Spanish – to build electrolyzer production facilities in the country. The projects, set to begin operations by mid-2026, will assemble alkaline and proton exchange membrane (PEM) electrolyzers ranging from 50 kW to 5 MW.
PV-driven absorption cooling system for arid regions
Scientists in Saudi Arabia have simulated a solar-powered single-effect absorption cooling system that uses water-lithium bromide as a working fluid, under the environmental conditions of Riyadh. Exergy and exergy rates are calculated for each level of the system, with optimal generator performance being found to peak at 80 C.
Dual-component controller for three-phase solar inverters can reduce overshoot to less than 0.33%
An international research team has conceived a dual-component controller for three-phase inverters that can reportedly achieve faster settling times, reduced overshoot and more stable current tracking compared to conventional controllers.
Key takeaways from Sunrise Arabia 2025
A recent joint event by Solarabic and pv magazine in Riyadh highlighted Saudi Arabia’s rapid push for clean energy and localization, with new factories and large storage projects taking shape.
Perovskite-silicon tandem solar cell based on hole selective monolayers achieves 29.8% efficiency
Researchers from Fraunhofer ISE and KAUST built a perovskite-silicon tandem solar cell that reportedly offers improved reproducibility. The device relies on self-assembled monolayers that result in low parasitic absorption and rapid charge extraction.
ACWA Power building hydrogen bridge between Europe and Middle East, North Africa
