Summary: This study integrates energy storage and low-carbon technologies under stability requirements and different climate conditions to analyze their role in decarbonizing the power system. The results show that batteries and hydrogen fuel cells have low penetration and negligible emission reduction. Compressed air storage has limited effectiveness in the short term but improves in the long term. Flexible generation technologies based on hydrogen turbines and long-duration storage provide the greatest decarbonization potential, covering 11-14% of demand in the short and long term. Decarbonizing the electricity system and achieving Paris targets is possible without significant cost increase.

Summary: In this paper, a hybrid energy system based on a combination of hydrogen fueled compressed air energy storage system and water electrolysis hydrogen generator is proposed to improve the utilization efficiency of renewable energy power generation. The system stores excess renewable energy by compressing air and/or producing hydrogen through water electrolysis, and introduces a hydrogen combustor to increase the air temperature during the discharging process. A thermodynamic model is built and energy and exergy analysis show that the proposed system can achieve a round trip efficiency of 65.11%, an exergy efficiency of 79.23%, and an energy storage density of 5.85 kWh/m3. The water electrolysis hydrogen generator and hydrogen combustor have the highest exergy losses among all components, and sensitivity analysis identifies the outlet temperature of the hydrogen combustor and specific energy consumption of the water electrolysis hydrogen generator as crucial factors influencing system performance.

Summary: The Mg90Ce5Y5 alloy was prepared by vacuum induction melting, and Mo, MoO2, and MoO3 were added to it through mechanical ball milling. The microstructure, phase evolution, hydrogen storage thermodynamics, and kinetics were studied using XRD, SEM, TEM, PCT, and DSC methods. The results showed that the internal phases of the Mo catalyzed alloy transformed into MgH2, CeH2.73, YH3, and Mo phases upon hydrogen absorption, while the hydrogenated alloy consisted of MgH2, CeO2, YH3, MgO, and Mo phases for the MoO2 catalyzed alloy, and MgH2, MgO, CeO2, Y2O3, and Mo phases for the MoO3 catalyzed alloy. REDOX reactions occurred between MoO2, MoO3, and the inner phase of the alloy. Compared to the others, the Mo catalyzed alloy exhibited a higher hydrogen absorption saturation ratio, and the MoO2 catalyzed alloy required less time to release H2 compared to the Mo and MoO3 catalyzed alloys. The dehydrogenation activation energy (Edes) of the samples showed an increasing trend in the order of MoO2 catalyzed alloy (110.18 kJ/mol).

Summary: Biological invasions, especially by Spartina alterniflora, are significantly impacting the structure and functions of coastal ecosystems in China. Urgent efforts to control the spread of this invasive species are hindered by the lack of time-series data. By using satellite images, this study successfully generated annual maps of Spartina saltmarshes from 1985 to 2020, revealing a continuous expansion of Spartina along the coast. The invasion history and frequency of changes were found to be influenced by latitude, with low latitudes experiencing longer and more frequent invasions. Human interventions have contributed to the decline in certain areas, but natural spread remains the primary driver of its extensive invasion.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
