Article Abstract
As the utilization of renewable energy sources continues to expand, energy storage systems assume a crucial role in enabling the effective integration and utilization of renewable energy. This underscores their fundamental significance in mitigating the inherent intermittency and variability associated with renewable energy sources. This study focuses on the involvement of photovoltaic (PV) plants in medium and long-term transactions. It also explores the participation of battery energy storage system (BESS) in electricity trading and frequency regulation ancillary services. The objective is to establish a strategic research model for maximizing the benefits of PV plant and the BESS in the energy arbitrage and frequency regulation markets. Sensitivity analysis was conducted to assess the impact of variations in both the rated power and maximum continuous energy storage duration of the BESS. Base on the NSGA-II algorithm and TOPSIS algorithm, an optimization model for energy storage capacity configuration is developed. The optimal capacity configuration and maximum continuous energy storage duration are determined through computational analysis, yielding values of 30.8 MW and 4.521 h, respectively. At this configuration, the daily average revenue is 2.362 × 10 yuan, the initial investment cost is 1.45 × 10 yuan, and the payback period is 4.562 years.

A series of Ni-MOF materials were synthesized by a one-step solvothermal method under different reaction conditions, including metal source, organic ligand, reaction time and reaction temperature. The results demonstrated that the Ni-MOFs synthesized with Ni(NO3)2•6H2O as the metal source had higher crystallinity and a more uniform crystalline structure than those with NiCl2•6H2O. Different organic ligands led to the formation of Ni-MOFs in various morphologies.

This review describes new strategies in the use of multifunctional organic alkalizers (OA) for the fabrication of advanced functional materials. OA facilitate solubilization and delivery of poorly solubilized drugs through the formation of drug-OA complexes and supramolecular gels. OA are applied for the synthesis of materials for biomedical, energy storage, catalytic, photovoltaic, sensor, and electronic applications.

This study presents a renewable electricity-driven microbial electrosynthesis (MES) system integrated with biological nitrogen removal (BNR) to achieve carbon-negative wastewater treatment. The MES system converts CO₂ into acetate, which is directly utilized as an internal carbon source for denitrification. Incorporation of biochar-derived conductive materials enhanced electron transfer, increasing acetate productivity to 1.

Hard carbon has emerged as the most widely studied and commercialized anode material for sodium-ion batteries (SIBs). However, improving the charge transfer kinetics within the plateau potential range of the hard carbon anode is crucial for the development of fast-charging SIBs. In this study, we prepared a novel composite material, ZAPA-1300, by uniformly mixing starch, asphalt, and zinc oxide (ZnO), followed by a two-step treatment process.
