Idrogeno verde
Advancements in electrolyzer tecnologie and renewable energy integration are key to sustainable green hydrogen production.

La produzione di idrogeno verde si basa sull'elettrolisi dell'acqua, alimentata da fonti energetiche rinnovabili come il sole e l'eolico, consentendo la generazione di idrogeno a zero emissioni di carbonio. Le tecnologie degli elettrolizzatori, tra cui i sistemi a membrana a scambio protonico (PEM) e alcalini, si concentrano sul miglioramento dell'efficienza, della durata e della scalabilità. Aspetti correlati includono lo stoccaggio, la compressione, la purificazione dell'idrogeno e l'integrazione nelle infrastrutture energetiche esistenti per applicazioni in celle a combustibile, sistemi power-to-gas e sintesi di combustibili sintetici. Questo archivio raccoglie pubblicazioni e brevetti recenti che descrivono in dettaglio i progressi nella progettazione degli elettrolizzatori, nell'accoppiamento delle energie rinnovabili, nel trasporto dell'idrogeno, nei protocolli di sicurezza e nello sviluppo del mercato, essenziali per la creazione di un'economia dell'idrogeno sostenibile.

Price and procurement optimization in hybrid competitive power supply chain under different bidding strategies

Published on 2026-05-20 by @OXFORD

Abstract: AbstractPower retailers procure electricity from generators and sell it at government-guided prices. Renewable energy electricity and fossil-fueled electricity compete in the market, with the government providing subsidies for renewable energy consumption. The price and procurement optimization of the hybrid competitive power supply chain under different bidding strategies contributes to the sustainable development of the power industry. The main findings of this study show that the total profit[...]


Our summary: This study analyzes price and procurement optimization in a hybrid competitive power supply chain with varying bidding strategies. It finds that simultaneous bidding maximizes retailer profits and aligns closely with centralized supply chain profits. Increased government subsidies for renewable energy lead to lower wholesale prices and altered procurement behaviors among retailers and generators.

Experimental analysis of soil thermal diffusivity for optimizing surface geothermal energy systems in arid environments

Published on 2026-05-12 by @OXFORD

Abstract: AbstractIn this research, the thermal behavior of shallow subsoil in Ghardaïa, Algeria, is experimentally investigated, with a focus on surface geothermal energy systems. From March 2020 to November 2023, air, surface, and subsurface temperatures (0–5 m) and other parameters such as solar radiation, humidity, wind speed, precipitation, and air pressure have been monitored. It was found that soil thermal diffusivity is a decreasing function of depth, with values of 7.31 × 10−7 m2/s and 5.[...]


Our summary: This research investigates soil thermal diffusivity in Ghardaïa, Algeria, focusing on surface geothermal energy systems. Measurements from March 2020 to November 2023 reveal that thermal diffusivity decreases with depth and stabilizes at 24°C below 4 meters. A predictive model shows high accuracy, suggesting future studies on deeper subsoil and renewable energy integration.
